Pelagian’s consultants have worked in the offshore oil and gas sector for over 25 years.

Our consultants started their careers in offshore oil and gas. We have followed the recent trends in platform connectivity using fibre optic and power cables. We have provided expertise from cable risk assessment and planning to cable protection and burial in close proximity to fixed seabed structures.

Case Study: Iraq ICOEEP Cable Burial Risk Assessment

Pelagian was contracted to provide expert personnel and consultancy services for the installation and remedial works for the Iraq Crude Oil Export Expansion Project (ICOEEP), located off the Shatt-al-Arab in the Persian Gulf.
Project work included provision of offshore client representatives to oversee the works and subsequent analysis of cable burial. As part of the analysis of the cable installation works, Pelagian conducted a detailed cable burial risk assessment.
The risk assessment considered the external threat to the installed cables from external factors such as shipping and fishing and formulated a remedial burial plan for the cables. The project highlighted challenging burial conditions close to existing pipelines and considered the long term operation of the cables in a busy and complex oil & gas shipping zone.

Case Study: Sakhalin Island Kirinskoye Umbilical Cables

Pelagian were contracted to provide route engineering services to the installers for umbilical cables, subsea distribution units and subsea manifolds as part of the Kirinskoye Gas Project located 30km east of Sakhalin Island in the Russian Pacific.
Pelagian’s work scope comprised the detailed route engineering of the umbilical cables to be laid into pre- cut dredged trenches This project presented a number of technical challenges including the translation of documentation from Russian, geospatial data management of dredging data and seabed infrastructure and engineering cables to withstand life in harsh environmental conditions, where ice and earthquake activity is commonplace.
The umbilicals were successfully installed in 2012 in water depths up to 90 metres. This project marked the first time that gas was extracted by a subsea production facility on the Russian shelf
