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
