Latest developments and news from the pipeline industry

EDITORIAL Welcome Message from the Middle East Oil and gas production companies operate onshore and/or offshore pipelines that may extend for hundreds of kilometers for transportation of hydrocarbons. Hence, pipelines represent a major asset that raises a number of challenges: • How to manage the design and construction of a new pipeline system? • How to manage the integrity of a pipeline system during operation? • How to abandon a pipeline i.e. take the pipeline system or part of it permanently out of operation? During the design and construction phases of the pipeline lifecycle, it is essential for the operator to ensure compliance of all elements of the design and construction activities to relevant statuary regulations and design standards. It entails various aspects including proper selection of competent consultants / contractors, third party verification and certification, safety / design audits and reviews etc. Several comprehensive design standards exist in the pipeline industry such as API, ASME, DNV, all of which cover the main aspects of pipeline design and construction. During the operation phase, the main challenge becomes ensuring the operation of the pipeline is conducted with due regard to public safety, environment and properties. This requires the development and management of a rigorous Integrity Management System (IMS). The integrity management is a continuous process covering the following main steps: • Risk assessment and integrity management planning • Inspection, monitoring and testing • Integrity assessment • Mitigation, intervention and repair At the end of the service life of a pipeline system, pipeline abandonment needs to be planned and executed with due regard of relevant national regulations, HSE issues and interference with third parties. Depending on the legis- lation, this may require physical cover or removal. Abandoned parts of a pipeline system may also continue being managed by the integrity management system e.g. they may remain covered by inspection plans. Each of the above issues represents a major challenge to the pipeline operator. As the trend of the oil and gas in- dustry continues towards more challenging environments, the challenges associated with the operation and integ- rity management of pipelines will become greater and more complex. Hence, collective effort is required from the industry for the continuous development of pipeline technology and best engineering practices through various channels such as internal R&D programs, joint industry projects (JIPs), partnership with research institutions etc. > Mahmoud Abdel Hakim, Subsea Pipeline Engineering Team Leader at ADMA-OPCO Mahmoud Abdel Hakim PIPELINE TECHNOLOGY JOURNAL 3
