Sep 29, 2020

  • Nexans will supply 46 kilometers of umbilicals as well as accessories and testing services to Subsea 7, the contractor responsible for the integrated subsea production systems serving the Sangomar Field Development project.
  • Nexans’ Halden facility will provide both static and dynamic umbilicals for each phase of the project, with deliveries commencing in 2022.
  • The Sangomar field, containing both oil and gas, is located 100 kilometers south of Dakar and will be Senegal’s first offshore oil development.

Paris, September 29, 2020 – Nexans has signed a contract with Subsea 7 to design and manufacture 46km of umbilicals for the Sangomar field, offshore Senegal. The umbilicals, produced by Nexans’ specialized facility in Halden, Norway, will provide vital hydraulic, control and instrumentation services for a stand-alone floating production storage and offloading (FPSO) facility and associated subsea infrastructure.

Nexans will deliver 13,471m of dynamic umbilicals which will be installed from north to south. Nexans will also provide 9.503m of main static umbilicals, 8,719m of production infield umbilicals, and 14,650m of injection infield umbilicals in the subsequent four phases of development.

Ragnvald Graff, Sales Director Oil&Gas says: "We are delighted to be designing and manufacturing the umbilicals for Senegal’s first offshore oil development. Nexans continues to lead the industry on umbilical technology, and we are excited to contribute our expertise and world-class products to this promising endeavor. Offshore oil development in West Africa has immense potential, and we’re thrilled to be a part of this important journey."

The Sangomar Field Development was discovered in 2014. Located 2km below the seabed floor, the field is spread over 400km², in water depths of 700 to 1,400 meters. The phased development includes the installation of a stand-alone floating production storage and offloading (FPSO) facility and subsea infrastructure that will be designed to facilitate subsequent development phases. These options include potential gas export to Senegal and future subsea tie-backs to other fields.
