The Sonam field development project is located in shelf concession OML 91, Escravos Area, offshore Nigeria, in water depths ranging from 7 m around Okan to 66 m at Sonam. The scope of work encompassed:

  • Transportation and Installation of the Okan PRP jacket, piles, deck and bridge.
  • Survey of pipeline route and the installation of the 32 km x 20 in. pipeline between Sonam NWP and Okan PRP.
  • Fabrication, load-out and installation of risers and subsea spools for Sonam NWP and Okan PRP.
  • Pre-commissioning and commissioning of the pipeline (hydro-test, dewatering, drying and nitrogen purging).

The contract was signed on 12 June 2015. Installation engineering activities and the preparations of project management documentation commenced immediately while field installation started with the pre-lay survey in November 2015.

The group utilised two of its DP3 Pipelay Construction vessels, Jascon 30, for the pipelay operations and Jascon 25, for the installation of the jacket, deck and bridge. Installation of subsea equipment as well as pre-commissioning activities were carried out by Jascon 8, one of the group's construction barges. Also a number of the group's tugs and barges supported the offshore campaign. The offshore work was completed in June 2016.

Jacques J. Roomans, STG/WAV President and CEO said: "I am delighted that the entire campaign was an overall success; it was delivered within our client's budget and technical specification. I am proud that the project team of West African Ventures was commended by Chevron for strongly aligning with their commitment to an Incident and Injury free campaign.”
