DeepOcean Secures IMR Agreements to Service Woodside's Sangomar Field

Ocean services provider DeepOcean has been awarded frame agreements by Woodside Energy (Senegal) B.V. to provide subsea inspection, maintenance, and repair (IMR) services at the Sangomar field located offshore Senegal, West Africa.

The Sangomar deepwater oil field is located 62.1 miles (100 kilometers) south of Dakar, Senegal. It began production earlier this month, making it the first offshore petroleum development to go onstream in Senegal. The field is estimated to hold proven and probable reserves of 230 million barrels of oil. The first phase of development involves production of up to 100,000 barrels a day through the Léopold Sédar Senghor floating production, storage and offloading vessel (FPSO).

The scope of work includes project management, engineering, and execution of subsea services such as inspection, survey, intervention, and maintenance, as well as additional services such as underwater inspection of the FPSO and standalone remote operated vehicle (ROV) operations, DeepOcean said in a news release.

The frame agreements were awarded to DeepOcean's subsidiary, Searov Offshore SAS, which will work jointly with its office in Séte, France. DeepOcean said that its local partner, Teranga Oil and Gas Services SARL, will play a vital role in delivering the scope of work. As a local Senegalese service company, Teranga Oil and Gas “shares DeepOcean’s vision of delivering innovative and quality services while maintaining the strictest compliance with local laws and regulations,” it said.

“We have extensive experience from similar IMR operations offshore West Africa, but this is our first project offshore Senegal and with Woodside. We look forward to being Woodside’s subsea IMR supplier here over the coming years and to demonstrate our competence and extensive pool of specialist subsea tools and underwater assets,” DeepOcean CEO Øyvind Mikaelsen said.

The Sangomar field features a permanently moored FPSO along with 24 subsea wells and associated subsea systems. The subsea system comprises wellheads and subsea trees, in-line tees, manifolds, flowlines and risers, flowline-end terminals, and subsea umbilicals.

“Sangomar is a large and impressive field development, with extensive subsea infrastructure. Our aim is always to inspect and maintain it as effectively as possible, thereby keeping costs and operational disturbances to a minimum for Woodside,” Mikaelsen added.

State-owned Petrosen holds an 18 percent participating stake in the Sangomar field, while Woodside owns the remaining 82 percent as the asset operator. Woodside’s net share of production is 60 million barrels. The project is being implemented by Woodside-Petrosen joint venture Rufisque Offshore, Sangomar Offshore and Sangomar Deep Offshore (RSSD).
