Quantitative Pipeline Risk Assessment (QPiRATM) Fire and Dispersion Analysis of a Subsea Gas Pipeline Leak Using Empirical Consequence Modelling
A subsea pipeline transporting gas in Malaysia has a smal l leak at its subsea flange at 70m water depth, located 140m away from the processing platform. The flange has undergone three rectification works; however, the repair works were unsuccessful to achieve zero leak. A Quant itative Pipeline Risk Assessment (QPiRATM) fire and dispersion...

Mittelplate is the largest oil field in Germany, located in the environmental ly sensitive Wadden Sea of the German State Schleswig-Holstein. An artificial Drilling and Production Island, named “Mitt elplate A” (MPA), was build early 1980`s on a tidal shoal and is operated by Wintershall Dea. In 2005, a 10 km, 10” stainless steel (1.4462 Duplex) p...

Safety is a crucial issue in operational activities. When performing a hot work operation on a live pipeline, it is very important to isolate the pipeline to prevent any dangerous event. In this paper, a newly and innovatively designed approach has been presented which has been used to isolate a 32” and an 18” offshore and infield pipelines from...

Total Exploration & Production & 3P Services
The paper describes development of In-Line Inspection (ILI) tools and equipment for deployment in 500+m water depth offshore oil production pipelines. Various design challenges were posed by the operational conditions and the pipeline operator. A joint development project is described in which 3P Services and Total E&P define the necessary tool...
