Sea Trucks has announced the conclusion of a pipe laying and construction campaign for Chevron’s Sonam field development project in Nigeria.

It also carried out survey of pipeline route and the installation of the 32 km pipeline between Sonam NWP and Okan PRP as well as the fabrication, load-out, and installation of risers and subsea spools for Sonam NWP and Okan PRP.

Located in the OML 91, Escravos Area, offshore Nigeria, the Sonam field is in water depths from 7 meters around Okan to 66 meters at Sonam.

Sea Trucks used two of its DP3 Pipelay Construction vessels, Jascon 30, for the pipelay operations and the Jascon 25, for the installation of the jacket, deck and bridge.

The Installation of subsea equipment, as well as the pre-commissioning activities, were performed using the Jascon 8, one of the group’s construction barges. The offshore work was completed in June 2016, Offshore Energy Today reports.
