is a natural gas boom coming? it is clear these days that all countries with an abundance of natu- gas reserves are pushing into the european market. high investments are being made for the construction of pipelines and lng plants. • russia will pump up to 86.5 billion cubic meters annually to europe via two new pipelines (nord stream 2 and turkstream), starting in 2020. • after an initial period of expansion, ten billion cubic meters will be pumped into europe via the southern gas corridor as well. • in addition, higher deliveries of lng from north africa, norway/scotland, and the middle east and north america (surpluses from fracking) are under discussion. the investment required is immense - but obviously will not be spared, because ad- ditional needs will arise - such as system-relevant gas-fired power plants, which are necessary to ensure the stability of the electricity networks during further expansion to incorporate renewable energy. lower rates of produc- tion within europe, the upcoming l-h gas conversion, and the circumven- tion of the ukraine cannot alone explain this development. pipeline technology journal 3 editorial ral dr. klaus ritter editor in chief in the meantime, the transport networks in europe are consolidated - german transmission system operators alone are investing over €4 billion according to grid development plans for the period 2016-2026. the best available material and equipment has to be used in the construction processes — as well as the operation and maintenance — of these new installations and existing pipelines, and they will have to be operated economically and reliably for many years to come because of the high levels of investment involved. this means seeking an ex- change of experience at a high international level in these international projects, in order to meet this need. the “pipeline technology conference” (ptc) and accompanying exhibition have been providing top-level exchange ex- perience for 12 years. this is the largest relevant event in europe. this year’s event took place from may 2 – 4 in berlin. it included immersive seminars and a scientific poster show, at which 12 research institutes presented their works. over 400 participants from more than 50 countries attend the 12th ptc. they had access to 20 innovative sessions, 80 innovative lectures, and two discussion sessions with 10 policy-makers providing an overview of the state of pipeline science and technology. session 1.1 was compiled by the dvgw. in the accompanying exhibition, 60 leading pipeline companies from all over the world were on hand for in-depth discussions. the event provided a comprehensive discussion platform for representatives from the oil, gas, water, and product pipeline industries. it had coverd technical topics regarding onshore and offshore issues, materials, planning, con- struction, automation, and integrity management. an iploca (international pipeline & offshore contractors associa- tion) regional meeting was also included in this year’s ptc. a 42-member advisory committee, which includes members from 13 nations, provided valuable support for this comprehensive program. the committee, previously led by dr. klaus ritter of the eitep institute together with mr. uwe ringel of ontras, is now led by mr. heinz watzka, former managing director of open grid europe and mr. dirk strack, technical director tal - transalpine pipeline. we are working constantly to uphold the continuous exchange within the international pipeline community. you are welcome to make use of the extensive opportunities we created. kindly find additional information on our websites or contact us directly via mail: email@example.com • • www.pipeline-journal.net • www.pipeline-conference.com yours, > dr. klaus ritter, president eitep institute

introduction many onshore pipeline projects traverse mountainous terrain, characterized by steep slopes, narrow ridges and limited right- of-way accesses. in these cases the knowledge of earth quan- tity to be relocated “in situ” or to be moved along the right of way, is essential to validate an economically viable construc- tion strategy. being aware of this aspect can avoid to reach a deadlock, which can increase significantly the construction schedule and the costs associated to project execution. the standard approach, commonly adopted in onshore pipeline projects, derives from civil road engineering works, where there is a massive use of cad softwares like autocad civil 3d®, civil design® or roadeng civil®. it can be noted that these applications are not developed, specifically, for on- shore pipeline projects. they typically demonstrate very long processing times, especially for elaboration of huge spatial databases associated to several hundreds of linear kilome- ters of topographic data and require constant inputs from the user for the entire workflow. since 2014 saipem felt the need to provide itself with a tool, able to perform quicker and more flexible estimation of earth movement due to grading of the right-of-way. objectives this paper aims at highlighting the process usually adopted in saipem to face the estimation of earthwork at the early stage of a pipeline project. while a bid study required short times in the evaluation of the quantities shown in the client’s documents, a feasibility study is characterized by quick changes in the fea- tures of the project due to the continuous flow of data. hence the need for a flexible, quick and easy application. all the phases of the process are ruled by a gis application, developed in python methodology the calculation algorithm used in seeve, like all the cad tools, is based on cross sections method, a development of the torricelli formula, which allows to calculate the volume of a prismoid between two areas: where: f1 and f2 are the areas at the both sides (spaced at a distance d) and fm is the area of the section at a distance of d/2 from the side sections. the formula above can be made simpler with the assumption that fm = (f1 + f2)/2 and the torricelli formula becomes: research / development / technology pipeline technology journal 7 the sections (also known as transects) are perpendicular to the pipeline centerline and have all the same length. below a sketch (figure 1) showing the hypothesis data used by seeve algorithm: figure 1: schematic view showing seeve hypothesis data. a set of sections are equally spaced along pipeline alignment. each section is divided in unit elements (di) and each of them is linked with its analogous in the next section through the cross section method figure 2: schematic view showing the ground elevations at sample points the inputs required by seeve include: • • • • a geometry, describing pipeline alignment, a digital terrain model (dtm), a table, describing the slope angles distribution along the right-of-way, a table, describing the distribution of direct and reverse lay along the pipeline route.
8 pipeline technology journal research / development / technology “seeve: a gis tool to early estimate earthworks in onshore pipeline projects “ matteo alesi from the pipeline alignment, seeve firstly creates the set of sections. then elevation values are extrapolated from the dtm points uniformly spaced along each section (figure 2). in the third and last step, it calculates the cut and fill volumes starting from the elevation values, previously obtained. seeve calculates the grade elevation through a fully or partially automated process based on user’s set of rules which can take into consideration both constructability criteria and/or optimi- zation of the mass haul balance (cumulative difference between cut and fill volumes). as indicated above, seeve is an application developed in arcgis desktop, using arcobjects and python as scripting language. seeve process can be schematized by the flow diagram below: figure 3 is a screen capture of the application, which is an arctoolbox. each arctool performes one of process phase, shown above. figure 3: seeve tools set figure 4: example of a final table of a bid study

pipeline open data standard (pods) next generation peter veenstra trc/pods association the pipeline open data standard (pods) association  develops and advances global pipeline data standards and best practices supporting data management and reporting for the oil and gas industry. this presentation pro- vides an overview of the pods association and a detailed overview of the transformed pods pipeline data model resulting from the pods next generation initiative. the pods association’s next generation, or next gen, initiative is focused on a complete re-design and mod- ernization of the pods pipeline data model. the re-design of the pods pipeline data model is driven by pods association strategy objectives as defined in its 2016-2019 strategic plan and reflects nearly 20 years of pods pipeline data model implementation experience and lessons learned. the next gen data model is designed to be the system of record for pipeline centerlines and pressurized contain- ment assets for the safe transport of product, allowing pipeline operators to: • • • • • achieve greater agility to build and extend the data model, respond to new business requirements, inter-operate through standard data models and consistent application interface, share data within and between organizations using well defined data exchange specifications, optimize performance for management of bulk loading, reroute, inspection data and history. the presentation will introduce the next gen data model design principles, conceptual and logical structures with a focus on transformation-al changes from prior versions of the model. support for multiple platforms including but not limited to esri arcgis, open source gis and relational database management systems will be described. alignment with esri’s arcgis platform and arcgis for pipeline referencing (apr) will be a main topic of discus- sion.
research / development / technology pipeline technology journal 13 the pods association is offering the pods lite data model free of charge to anyone wishing to evaluate and understand how the pods pipeline data model can support their needs. peter veenstra pods association overview since 1998, the pods association has been focused on providing comprehensive, open, vendor-neutral, scalable, and proven standards and an enterprise database archi- tecture focused on increasing the safe- ty and integrity of pipelines worldwide. pods association membership leverages a broad knowledge-base built on a global network of over 170 pipeline operators and service providers to access and share a wealth of technical knowledge and experi- ence. association members work collabo- ratively to develop, refine and benefit from use of the pods pipeline data model. figure 2 – pods association strategic goals the pods association supports the growing and chang- ing needs of the pipeline industry through ongoing development and maintenance of its pipeline data model and standards. this work aligns with goals set forth in the pods strategic plan as defined by the pods board of directors and technical committee on governance. pods standards are developed using a consensus-based approach with contributions from association members and partner organizations. development and stewardship of pods standards is guided by a well-defined gover- nance structure as illustrated in figure 1. pods association activities and investments are performed in alignment with goals and objectives defined in the associ- ation’s 2016-2019 strategic plan . the following strategic goals guide pods association activities: • goal 1 – establish an industry-recognized core logical data model and vendor-neutral physical data model with implementation resources, • • • • • goal 2 – steward open-interchange specifications for data sharing, goal 3 – provide advocacy services for member organizations, goal 4 – offer clear and robust standards implementa- tion guidance and pods foundational train- ing services, goal 5 – strengthen and optimize pods governance, goal 6 – grow membership based upon solid value proposition to member organizations. through execution of the strategic plan and governance approaches the pods association provides the following bene- fits to its member organizations: • pods lowers the risk, cost, and time required to implement a pipeline data management system. maintaining a single pipeline data repository includ- ing geospatial/locational information enables pipeline operators to improve the quality, quantity and timeliness of pipeline information managed. pods is an open standard allowing members to choose implementation platforms and software applications based on features, cost and usability. multiple vendors may develop software products that interact with the pods database. by using the pods data model, pipeline operators are not tied to a vendor’s proprietary data model. • figure 1 – pods association governance structure
line data model implementation experience and lessons learned. a primary driver was the need to create a more stream-lined and efficient data model. secondary drivers were to isolate the seeming focus on north american regulatory drivers and a lack of standards or documenta- tion describing what constituted a valid implementation of the pods database (including data structure and content). lesser drivers were the need to move away from solely describing geographic location by linear referencing and as on-line events. 14 pipeline technology journal research / development / technology • pods promotes best practice and optimized business processes and workflow. members will experience simplified data transfer between software applications and multiple databases; clear, concise definitions; and the ability to clearly delineate data ownership. pods next generation transformation the pods association is committed to continual modern- ization and transformation of pipeline standards and related implementation services. the pods association is redesigning and modernizing its standard and implemen- tation guidance to be more agile, transpar- ent, easy to use and to support interoper- ability – next generation, or “next gen”. pods next gen will include a new core set of tables, modules to extend the core, a new data exchange specification, more robust documentation to guide implemen- tation and guidance for migrating data to the new standard. the new pods standard will support use of esri technology includ- ing the new apr solution as well as other relational database (rdbms) and map- ping/geographic information system (gis) technologies. the pods association start- ed development of its next gen standard in 2016 and plans to fully complete the effort in 2018, with incremental deployment to facilitate early adoption. figure 3 – drivers for standards transformation transformation scope and outcomes – pods pipeline data model 7.0 pipeline operators, services providers and regulatory agencies will all benefit from enhancements to pods standard. next gen will result in a simplified data mod- el with enhanced capabilities resulting in cost savings and enabling increased effectiveness in pipeline data management and reporting activities. pods association members will achieve greater agility to build and extend the core data model to better respond to new business requirements, realize improved ability to share data within and between organizations using a well-defined data exchange specification, optimize performance for man- agement of bulk loading, analysis, re-route, inspection and history data, efficiently satisfy regulatory reporting re- quirements and better ensure consistent implementation of pipeline standards for enhanced interoperability. the pods association has chartered a dedicated working group, comprised of individuals from pods association governance bodies as well as association members (op- erators and service providers), to guide next gen design and development activities. the next gen working group initially established the drivers for standards transforma- tion, as shown in figure 3. the next gen initiative will result in a new data model – pods pipeline data model version 7.0 – as well as an xml-based data exchange specification (des) and new documentation providing clear and concise implementa- tion guidance and instructions. the pods association will provide guidance on configuring and extending the core pods pipeline data model to meet organization-specific requirements and objectives. figure 4 illustrates the full scope of transformation activ- ities. items shaded in blue represent existing pods data model elements and implementation resources that are be- ing transformed. items shaded in red are new to the pods scope and include support for open source database and gis platforms, support for big data analysis, a business in- telligence/presentation layer and application programming interface (api) and a new data exchange specification. more information on the next gen initiative and outcomes can be found on the pods web site . first release of transformed standards – pods lite the re-design of the pods pipeline data model is driven by pods association strategy objectives as defined in its 2016-2019 strategic plan and twenty years of pods pipe- a first incremental release of the transformed pods pipeline data model was provided in early 2017. this first release, referred to as pods lite, includes a subset of
research / development / technology pipeline technology journal 15 • support location and spatial representa- tion – the data model will provide flexibility to include or exclude spatial representation of assets and events either by coordinates, linear referencing or inclusion in a station or facility. • support interoperability – the data model will support data exchanges between systems and figure 4 – transformation scope the new pods pipeline data model version 7.0 core and includes the minimum set of tables required to identify the location of and safely manage the operation of a pipeline. • work streams within an organization as well as data exchanges between organizations. ease of use and understanding – the data model will be easy to understand, implement, extend and use. pods lite, while a preview of the full data model, is de- signed as a stand-alone product and is free for download and use by all interested parties, including pipeline oper- ators and service providers that are not currently pods association members. the first release of pods lite is being made available in the esri geodatabase format. this version, referred to as pods lite for apr, will work with esri’s arcgis for pipeline referencing, or apr, extension. this is possible because esri’s apr solution will work with any data model that meets certain requirements; the pods pipeline data mod- el version 7.0 and pods lite meet these requirements. the pods association and esri have worked collabora- tively on the development of pods lite for apr. pods lite, though, is not specific to esri or the esri apr extension to the arcgis platform. pods lite will be released for open source gis, oracle and sql server rdbms platforms in spring 2017. transformation design principles the following design principles are guiding transformation of the pods pipeline data model: • design for the future – the next pods pipeline data • • • model will be transformational not an incremental update to the existing standard. solid core coupled with agility and flexibility – the data model will allow for independent extension of the model in a flexible fashion yet in alignment with core modeling and design principles. single logical data model – a single data model will be used to support all possible physical data imple- mentations (esri geodatabase, rdbms schema, native spatial data types etc.). support time and history – the data model will support time-based events and track asset lifecycle history. pods data exchange specification (des) a key new component to the pods standard is the inclu- sion of a data exchange specification (des) to facilitate data translations between the pods pipeline data model versions 7.0 and earlier as well as other data models. the des also enable system integration via service-oriented architecture (soa) approaches. the des will standardize and modernize data management and reporting across the pipeline industry. the des will be implemented using extensible markup language (xml) . the new pods data exchange specification can be used for the following purposes: • schema definition – the des can be used to define the schema of a pods data model implementation. the schema is defined as tables, attributes in those tables, relationships between tables, attribute data types, cardi- nality and the domains (or valid value lists) for those at- tributes. the objective of defining the schema is to allow data to be defined, described and validated before it is loaded into and committed to a gis or database system. • data validation – the des can be used for data vali- dation. once a pods database schema is described using the des (in xml format), data can be loaded to the schema and validated for compliance with schema definitions and rules. • data transfer – the des will allow transfer between different databases and software systems. the pods des is similar to the esri xml workspace document  used for the same purposes except that the pods des will include metadata describing these data and structures based on pipeline terminology. service orientation – web services can be established to enable production and consumption of data be- tween systems using soa approaches. web services can utilize the pods des as the means for packaging and structuring data exchanged between systems. •
16 pipeline technology journal research / development / technology the xml specification of the des is currently under devel- opment by the pods next gen team and will be available for evaluation in 2017. even at the final release of the des, users will be responsible for developing the automation routines, software or services to read/write to the data exchange specification. the pods association anticipates software tools will be developed by service providers that will enable use of the des. one logical model, multiple platform implementations a key design principle for next gen is to manage a single logical data model supporting implementation on differ- ent gis and database platforms. in prior versions of the pods data model, each implementation “pattern” has its own logical data model (i.e., one logical model for oracle relational, another for pods esri spatial geodatabase, etc.). this single logical data model must support multi- ple rdbms technologies as well as geographic feature storage technologies. and iso/ts 19103 (geographic information - conceptual schema language) . the application schema also con- forms to iso 19136:2007 geographic information - geog- raphy markup language (gml)  annex e, section 2.1.1 of 19136:2007, which defines a valid input to a standard set of uml to gml encoding rules also defined in annex e of the gml standard. the transformed pods logical data model model is man- aged using sparx systems enterprise architect  soft- ware. using enterprise architect, the pods logical data model is profiled, flattened and generated as a physical data model for implementation in gis and rdbms. figure 5 illustrates the physical data model (“implementation patterns”) supported by this approach. sparx systems enterprise architect and additional supporting software tools including shapechange and oxygenxml are used to generate either an esri xml workspace document or a data definition language in standard query language (sql) format. this procedure is summarized in figure 6. to meet this need, the transformed pods logical model utilizes geographic markup language (gml) to model the concep- tual and logical portions of the model including abstract data type and abstract class definitions. the pods logical model is a unified modeling language (uml) application schema conforming to inter- national standards organization (iso) 19109:2005 (geographic information - rules for application schema)  figure 5 – supported implementation patterns figure 6 – developing physical database templates from a common logical data model
this logical modeling approach is being implemented with pods pipeline data model version 7.0 (and pods lite) and allows for the transformation of the application sche- ma into other models (such as a model conforming to uml profiles for arcgis) and physical representations such as xml schema or sql data definition language (ddl). “the pods next generation effort is driving transfor- mational change resulting in realization of a data model framework and data exchange mechanism positioned to serve the needs of the global pipeline industry.” peter veenstra additional design details the transformed pods logical data model and physical implementation patterns, as introduced directly above, also adopt and employ the following design approaches: • shape or geometry columns – are included in any table representing a geographic feature (in the typical geodatabase “shape” column is used). this allows users of the pods model to capture the geographic and locational properties of pipeline assets and events. • linear referencing system architecture – the transformed pods logical model adopts and utilizes the esri arcgis for pipeline referencing (apr) core tables as a basis for managing linear referencing systems (lrs), including for non-esri deployments as well. these tables form the basis of the apr soft- ware but also allow for the storage and management of nearly every conceivable method for storing and managing linear referenced networks and features. [ through adoption of the esri lrs, pipeline oper- ators may use the esri apr software solution to manage data organized using the pods pipeline data model version 7.0. [ the pods lite model adds some additional fields to these tables but they are, in essence, unchanged from the core tables of the apr lrs model. [ the lrs tables included in pods lite can be • instantiated for use in other non-esri implementa- tion patterns. the apr lrs tables provide enough flexibility to manage any linear referencing mode or implementation scenario. • use of different location methods in a single database – the pipelinefeature abstract class in the trans- formed pods logical data model is designed to support features located by coordinate position and research / development / technology pipeline technology journal 17 linear referencing or to support the implementation of a null geometry. this allows the new logical model to be used to manage a list of pipeline assets, conditions and activities without storing geometry. [ a benefit of this approach is it provides flexibili- ty for storing (or not storing) the geometry of an entity at the row level, i.e., for individual features or records in the database. [ using this approach an entire pipeline system could be managed using coordinates only (akin to a geometric network found in gathering and distribution systems) or the pipeline could be managed exclusively with linear referencing (commonly found in transmission pipeline sys- tems) or most importantly, as a combination of both methods. [ the pods data model supports this flexibility for geospatial data management. this is a significant departure from the stationing only design of pre- vious pods data models. • simplified class and attribute names – class and attribute names were simplified and reduced to the most salient and commonly found descriptors found based on the experiences of the pods next gen working group. classes sharing identical schema have been merged together. the layermetadata class can be utilized to define the editing and validation behaviors for merged sche- mas using definition queries or filters to specify par- ticular data types within a merged table. camelcase format is used to describe these in the logical mod- el, however, tools used by pods to create physical database schemas and templates for specific imple- mentation patterns will support an implementation option of using upper case letters and “_” underbars in table and attribute names within the physical implementation of the model, when required. code lists to store valid values – code lists are maintained in the pods logical mod- el. when creating physical database schemas and templates for specific implementation patterns, these code lists are instantiated using approaches unique to that pattern. for example, when creating pods lite for apr templates (i.e., an esri geoda- tabase), the code lists are mapped to esri geoda- tabase domains. the pods logical data model will support domains (for geodatabase implemen- tations), code lookup tables (for sql ddl imple- mentations), and code lists (for the xml schema data exchange specification). code list values and descriptions are (typically) synonymous. standard definitions for character based domains are 50 characters for the code values, and 255 characters
18 pipeline technology journal research / development / technology for the descriptions. all attempts were made to keep codes and descriptions in sync and to remove magic numbers or abbreviated code values. • pods lite for apr and esri relationship classes – the geodatabase implementation of pods lite does not contain explicit relationship classes. since this release of pods lite is an esri geodatabase and the accepted standard for geodatabases is the removal of relationship classes, this version of pods lite will adhere to that policy. subsequent rdbms releases of pods lite will enforce relation- ships and referential integrity. • database platforms – when instantiating the pods logical data model to different implementation patterns, the following approaches are applied: ◦ rdbms – relational database management system – the software that creates, stores and manages the underlying database. • oracle  – with sde (sdo_geometry/st_geometry) or without using native spatial type (st_geometry) • editing paradigm – the underlying spatial data and attribute informa- tion in a pods database can be loaded, edited and accessed at a tabular/root level using the following tools and approaches: ◦ arcobjects\arcpy  – assumes geodatabase, versioning, and/or spatial views – all or part of the edit process occurs using esri technology ◦ other gis library – application programming interface (api) compo- nents for editing spatial and attribute information ◦ sql – all geometry and attribute data are updated against native spatial types and columns us- ing sql to access underlying rdbms spatial libraries (sql) ◦ combination – combination of any of the above. using these rdbms, spatial data type and editing paradigm parameters many different physical implemen- tations of the pods database can be supported. these parameters reflect the underlying rdbms and gis tech- nology (in particular esri), and allow for existing imple- mentations to be supported. • ms sql server  – with sde (sde binary or geometry) or without using native spatial type (sde binary) • postgis  – with sde (st_geometry) or without using native spatial type (st_geometry) “pods lowers the risk, cost, and time required to im- plement a pipeline gis. maintaining a single pipeline data repository helps pipeline operators to improve the quality, quantity and timeliness of pipeline information managed.” peter veenstra • spatial data storage types – spatial data are stored using native data types unique to a given rdbms platform, or alternately using the geodatabase or ogc well-known text (wkt) linestring type. spatial types are used to store the shape (geometry) of the feature: ◦ sde_binary  – native sde binary data type ◦ st_geometry  – native rdbms spatial data type (oracle, postgis) ◦ geometry  – native rdbms spatial data type (ms sql) ◦ sdo_geometry  – native rdbms spatial data type (oracle) ◦ ogc wkt linestring  – open geospatial consortium well-known- text linestring next generation transformation road map the pods association is currently working to complete the release of the pods 7.0 model utilizing the design principals and approaches summarized above. the pods lite model supporting esri arcgis for pipeline referenc- ing (apr) has been released in early 2017 and support for oracle, ms sql server, postgis relational versions is planned for mid-2017. work defining the core tables of the pods 7.0 release, defining offline storage of inspection data, defining how tables are added to the core model (via modules), and defining how history will be managed are in the planning stages and will begin in 2017 with completion and release of the full pods pipeline data model version 7.0 core planned for early 2018. additional capabilities including support for big data, business intelligence presentation layer, etc. will follow shortly thereafter.

engineering tool for automatic selection and performance calculation of turbo compressors and drivers manuel bollgrün ilf beratende ingenieure gmbh abstract selection of compressor type, compressor configuration and driver type is one of the principal issues during early design phases of compressor stations or pipeline systems. as soon as potential locations and oper- ating requirements of new compressor stations or compressor units in natural gas transport systems are defined initial compressor selection begins. to support decision making and system design of compressor stations or complete pipeline systems a comput- er tool has been developed, allowing quick and profound compressor selection and performance calculation.
research / development / technology pipeline technology journal 21 “the ilf tool cosito automatically searches for a com- pressor map with minimum shaft power requirement of the defined operating points.” manuel bollgrün in some cases, selection of the optimum compressor con- figuration and driver type is very obvious, in other cases a multitude of variables can make the selection difficult and a profound compressor study is necessary. with a multi- tude of compressor configurations to be compared and for short-term performance calculations, it is beneficial if the designer of a compressor station can rely on his own tools for compressor selection and performance calculations, in addition to the technical support by manufacturers. the tool which is presented in this article facilitates the selection of compressors and compressor configura- tions and has proven its applicability over the past 10 years. based on the project specific ambient conditions, gas properties and operating points, the ilf tool cosito automatically searches for the optimum compressor map concerning shaft power requirement and calculates shaft power requirements for each individual operating point, based on its location in the compressor map. with the shaft power requirements, power consumption of either electric drives or gas turbine drives will be the result of the automatic calculation. the ilf tool cosito automatically searches for a com- pressor map with minimum shaft power requirement of the defined operating points, also taking into account relative operating times of the individual operating points. the functionality of the automatic compressor selection and performance calculation is described in the following. the complete calculation routine which is schematically shown in figure 1 is carried out by the tool within a few seconds at the touch of a button. the tool is programmed in visual basic for applications (vba) and has been steadily developed and extended over the past 10 years. required input parameters for the program to start cal- culations are gas mixture (components and molecular weights) and operating points (suction and discharge pressure, suction temperature, throughput and relative operating times). in case of gas turbine compressor drives, also site ambient conditions (elevation and ambi- ent temperature) are required. the selection starts with a compressor designed for max- imum head and maximum flow of the defined operating points and iteratively searches for the optimum compres- sor map with the lowest shaft power requirements. figure 1: flow chart of cosito calculation routing the estimation of compressor characteristic values (rated compressor speed and rated efficiency) is implemented as follows. in case of gas turbine driven turbo compres- sors, the rotational speed is typically predefined by the power turbine speed. this practice has been implement- ed in the tool. with an averaged curve through rated speeds and power ratings of gas turbine drives available on the market, the turbo compressor rated speed is esti- mated. alternatively the user of the tool can also define the rated speed himself. the impeller diameter and the number of compressor stages are estimated using the head coefficient ψis in the range of 0.95. rated poly- tropic compressor efficiency of the turbo compressor is estimated based on a function of mean volume flow coefficient φm and impeller tip diameter. the way how the compressor performance map and with that compressor speed and efficiency for each individual operating point are estimated is described as follows. simulation of the compressor map is based on the fan law approximation, meaning proportionalities between rotational speed, volumetric flow and head. these pro- portionalities say that in centrifugal compressors the volumetric flow is proportional to compressor rotational speed (q ~ n) and compression head is proportional to the square of compressor rotational speed (h~n²). these relationships are most accurate for single-stage compressors and ideal gases. for multi-stage compressors
22 pipeline technology journal research / development / technology with gas that deviates from the ideal gas laws, the accuracy of the fan laws is reduced but still good for this application. based on these proportionalities, quadratic equations are used defining the relations between compressor head, flow and polytropic efficiency. the parameters of these quadratic equations, basically expressing the steepness of the constant speed and efficiency curves, were defined using a list of different compressor maps from various manufacturers. also the compressor operating range limitations surge and choke were defined based on this collection of actual compressor maps. summarizing, with a certain compressor design point selected by the tool in the previous program step, the ilf compressor tool cosi- to simulates a compressor map which represents the av- erage capabilities of the recognized manufactures. with quadratic equations, the constant speed and constant efficiency curves of a compressor map can be drawn and the speed and efficiency of a given operating point can be automatically calculated. after definition of a compressor performance map, the next program step is calculation of performance values of the operating points. at first for each operating point its location in the compressor map is determined. if the oper- ating point is outside of the compressor operating range it will be determined if either the operating point can be made with recycling or throttling or if it is not possible to operate the operating point (if requirements exceed the compressor’s maximum head, flow or speed). based on estimated compressor rated efficiency and the location of each operating point in the compressor map, for each operating point gas parameters and thermody- namic properties are calculated, such as specific heat capacity (based on aly-lee-equation), polytropic expo- nent, discharge temperature, real gas factor zavg (based on soave-redlich-kwong-equation) and polytropic head. with these values required shaft power can be calculated for each operating point. the above described approach represents calculation for pow- er requirements of one potential com- pressor. this is au- tomatically repeated multiple times after variation of the compressor design point to optimize the compressor selec- tion and find the ideal compressor with minimum shaft power requirements. an exemplary com- parison of the pre- dicted compressor operating range by ilf compressor tool cosito (in red) and the actual compres- sor map as provided by the supplier is shown in figure 2. it can be seen that the predictions and compressor perfor- mance estimations were very realistic which proves the usability of this pre- sented tool. figure 2: comparison of compressor maps by cosito and supplier

internal coating –a must in gas pipelines amrinder singh indian oil corporation limited northern region pipelines abstract pipelines have become an essential part of the system to transport and supply of petroleum gases. conventional- ly, gas pipelines are coated externally for anticorrosive properties. the inclusion of condensates, sour gases and other corrosive substance in traces cannot be ruled out during pipeline operation over a period of its intended usage. the external coatings are not able to provide resistance to corrosive substances and cannot be cleaned using pigs. the corrosion of pipelines through condensates, accumulated corrosive substances has caused severe damages to pipelines, mankind and economics worldwide. this article reviews the benefits of considering an internal lining for gas transmission pipelines and the re- lationship between the internal surface roughness, the pressure drop across the pipeline and the maximum flow rate of gas through the pipeline.
research / development / technology pipeline technology journal 25 introduction a fluid in motion in a pipeline is subjected to various fric- tional resistances. friction occurs between the fluid flow in a pipeline can be either laminar or turbulent. transportation of natural gas in pipelines at high flow rates exhibits turbulent flow and in such conditions a laminar film can be formed at the pipe wall/fluid interface. this will reduce the friction between the fluid and pipe wall with a subsequent reduction in the pressure drop through the pipeline and an increase in flow capacity. the creation of this laminar film is dependent upon the surface roughness at the pipe wall/fluid interface and, to a lesser degree, the extent of the turbulent flow and the fluid velocity. however, the laminar film created at the pipe wall is very thin and the maximum peak height of the profile of the pipe wall surface may be sufficient to protrude through it. this protrusion results in a disruption of the flow pattern of the laminar film, effectively creating a turbulent flow pattern adjacent to the wall and increasing the pressure drop across the pipeline and reducing its flow capacity moreover the gas pipelines are at high risks of internal corrosion which is a major factor contributing to failures and leaks in pipelines. corrosion along the bottom of the pipeline is the primary mechanism leading to failures in uncoated carbon steel pipelines. the corrosion occurs due to presence of any of the following elements in the water o2, co2, h2s, bacteria, chlorides, scale, or suspended solids (figure 1) internal coatings have been used on some gas transmis- sion pipelines to improve product flow by reducing drag and eliminating dust. such coatings can be somewhat ef- fective in controlling internal corrosion, but they are very difficult to apply uniformly, which impacts their effective- ness. in lieu of coatings, some operators have attempted to install plastic or high-density polyethylene liners or inserts in their pipelines. international standards today, two international standards are well recognized when technical requirements for flow efficiency coat- ings are considered: the american petroleum institute’s api 5l2 `recommended practice for internal coating of line pipe for non-corrosive gas transmission service’; and iso 15741`paints and varnishes – friction-reduction coatings for the interior of on and offshore steel pipelines for non-corrosive gases’. the en 10301 standard „steel tubes and fittings for on and offshore pipelines – internal coating for the reduction of friction for conveyance of non- corrosive gas’ is very similar to iso 15741. “internal coating leads to a reduction in the pressure drop in the pipeline and thus to an increase in the flow rate of natural gas through it.” amrinder singh figure 1: corrosion on a steel surface internal coating systems fusion bonded epoxy typically when fusion bonded epoxy (fbe) is referenced, it is assumed to be for the external protection of line pipe but it is little known/practiced that these are also effective as internal coatings. there are wide arrays of fbes, primed and unprimed, that have proven to be successful in the area of corrosion protection, hydraulic improvement and deposit mitigation for the internal of line pipe. fbes are thick film coatings usually with a dry film thickness (dft) of less than 400 microns. advantages of fbe coatings are their adhesive properties, their chemical resistance,
26 pipeline technology journal research / development / technology their high degree of flexibility and good impact resistance. drawbacks of fbe coating systems are the high degree of surface preparation required for their application as well as a curing temperature in excess of 200°c, all of which requires `shop applied´ coating application. polyamide coatings internal coatings based on polyamide chemistry are defined as thermoplastics. unlike thermoset materials, thermo- plastics do not undergo a final curing step at elevated temperatures. instead, these materials are applied at very high temperatures and are then led through a controlled cool down process that will vary depending on the type of polyamide and the desired final properties. due to this, heat resistant polyamide powder coatings are primarily plant-ap- plied coating systems. polyamide coatings have advan- tages over fbe coating materials due to a higher degree of flexibility and less damage experienced from mechanical impact. polyamide coatings generally require a liquid epoxy or phenolic primer in order to ensure good adhesion. flow efficiency coating flow efficiency coatings (fec) are thin film epoxy coatings applied in natural gas pipelines to smooth the internal pipe surface for improved flow. application of fec replac- es the internal rough surface of a steel pipe with a smooth surface finish which reduces friction and turbulence to in- crease flow efficiency. this may allow for use of a smaller diameter pipe or lower compression requirements result- ing in reduced capital and operating costs. after applica- tion of fec, the clean internal surface of the pipe provides corrosion protection prior to installation and allows for easier visual inspection. the cleaner surface reduces the cost and effort of drying the pipe after hydrostatic testing. benefits of internal coating • reduction in the pressure drop in the pipeline and thus an increase in the flow rate of natural gas through it. • a decrease in the pipeline outer diameter in the de- • • • sign phase of the project in order to achieve the same flow capacity. reduction in power consumption for compression of the gas to

pipeline operating valves, as well as clogging instruments and filters, lowering the efficien- cy of compressors, and contaminating the supplied product to customers. this is a world-wide problem that affects most gas pipeline operators. in a study conducted by zamorano (2002) the economic benefits of using internal coating were addressed .the study was based upon internally coated pipe on the argentine side of the gas atacama pipeline system. the argentine section is 530 km of 508 mm od pipe, and was coated with a solvent-based epoxy flow efficiency coating: the chilean section was left bare due to project capex restraints .the economic analysis in the study was based upon the existing capacity of the pipeline and two capacity expansion scenarios. a conclusion of the study was that the economic benefits of using internal flow efficiency coatings were more substantial at higher gas flow rates (see figure 2). based on the operational conditions the effect of the internal coating under three different scenarios was studied: scenario 1: capacity enhancement with existing gas com- pression facilities due to internal coating. scenario 2: next capacity expansion from 4.13 to 5.6 mmscm/d. scenario 3: future capacity expansion up to 8.5 mmscm/d. the main conclusions reached with this study were: the effect on pipeline, capacity of the internal roughness is not relevant in the range of low to medium flows, up to 4 mmscm/d. for flows greater than 4 mmscm/d, it becomes a very import- ant factor on flow efficiency and cost savings. according to john campbell and co. analysis, the pipeline pressure drop increases very rapidly with the roughness factor of pipe internal. for a liquid pipeline, the percentage change of fric- tion pressure drop if 20 percent maximum and for the gas pipeline the maximum change is more than 200percent. a summary of the analysis is shown in figure 3. in a case study, conducted on and 8 inch gas pipeline, it is shown that the internal surface roughness is directly proportional to percentage pressure drop in a pipeline. this study is based on the procedure, by joe honeywell, for calculating pressure drop in liquid pipelines which is further extended in gas lines. in this study it is shown that “how sensitive is friction pressure drop with the wall roughness factor?” and to study the same, the effect of wall roughness factor for two case studies is collated in the first case study, an oil pipeline with a flow rate of 0.313 m3/s (170,000 bbl/day) and in the second case, a natural gas pipeline with a flow rate of 22.913 sm3/s (70 mmscfd).the calculated friction pressure drop as a func- tion of roughness factor is presented in figure 4. as can be seen in figure 4, friction pressure drop increas- es very rapidly with the roughness factor. for the liquid pipeline, the maximum change is 20 % but for the gas pipeline the maximum change is more than 200 %..
research / development / technology pipeline technology journal 27 in summary, contrary to liquid pipelines the gas pipelines are very sensitive to wall roughness and using smooth pipe can reduce friction pressure drop consid- erably. this in turn lowers the opex. in 1994-95, a study was carried out on a 48-in gas pipeline, by nova corp which estimated the saving of 2.8 million ca- nadian dollars due to internal coating of pipeline. the study’s objective was to obtain data for realistic pipeline simulations for evaluating the economics of coating used to enhance flow efficiency. the study showed that internal coating is economi- cally justified in larger diameter pipelines with moderate to high flow rates. based on this study 95miles of 48in gas pipeline was internally coated. in addition to cost savings, internal coating is beneficial in mitigation of black powder development in gas pipelines. black powder development black powder can develop within gas pipelines due to the reaction of iron with condensed moisture, containing o2, h2s & co2). black powder could come from the following sources: • mill scale (iron oxides – fe3o4), from the pipe manufacturing process through high temperature oxidation of steel flash rust (fe2o33, feooh) from hydrostatic testing water corrosion; internal pipeline corrosion (microbi- ological influenced corrosion – mic) or h2s reaction with steel; carry-over from gas gathering systems. • • • black powder may be mechanically mixed or chemically combined with any number of contaminants, such as water, liquid hydrocarbons, salts, chlorides, sand, or dirt. chemical analyses of the material have revealed that it consists mainly of a mixture of iron oxides and iron sulphi- des. figure 5 provides an example of the chemical composition of a black powder. figure 2: difference in pressure drop - internally coated versus bare pipe figure 3: summary of the analysis figure 4: impact of roughness factor on % change of frictional pressure drop relative to a smooth pipeline in oil and gas transmission lines
28 pipeline technology journal research / development / technology conclusion internal coatings have demonstrated their applicability as a flow efficiency coating of gas transmission pipelines in terms of operation and maintenance since the 1960s. fur- thermore, the coatings have shown to help solve technical problems, such as the formation of black powder. existing modern coating materials have been designed to cope with the technical requirements, as listed in the api 5l2 and iso15741 international standards and by taking account specific requirements, such as surface profile roughness. author amrinder singh indian oil corporation limited northern region pipelines asst. manager (maintenance) firstname.lastname@example.org figure 5: black powder composition using the xrd technique organic coatings, such as high-solids solvent based epoxy polyamine films, reduce drag but have the added benefit of preventing black powder. typical application measures 2-3 mil (50-80 μm) thick to cover pipe roughness (ry5 = 30 μm). used globally for 55 years in more than 300,000 km of pipelines, they have good ageing properties, show- ing no degradation after 30 years exposure to dry. international standards (api 5 l 2 and iso 15741) cover specifications of internal coating for gas pipelines. internal coatings are a cost-effective means of preventing black powder in new pipelines. they are, however, very difficult to apply and not cost effective in existing pipelines, partic- ularly buried pipelines. steel pipe delivered to the coating yard has a relative roughness of the order of 20 μm. however, once in produc- tion, this relative roughness may exceed 50 μm depending upon the corrosion products formed on the surface. this formation may be due to the period of time and the con- ditions the pipe was stored in prior to installation, due to hydrostatic testing, and the corrosive nature of the fluid being transported. using hydraulic pipe flow software, the pipe roughness versus maximum achievable flow rate can be plotted for a constant discharge and arrival pressure. stay up to date with ptj news, the free bi-weekly newsletter will keep you informed about current world- wide developments and events within the pipeline industrie. don’t miss the op- portunity to get a well summarised composure of the recent main topics regarding this rapid industry combined with featured scien- tific articles out of the giant knowledge- base from the ptj.
