Landmark: First subsea development in Congo's continental shelf

The project embraces two structures – Bilondo and Mobim. Both are an oil discovery. The development concept is based upon a subsea production system connected via a riser system to the floating production unit with facilities for process and accommodation. FMC Technologies is delivering 14 subsea trees and two template structures with manifolds. The agreement also includes production control systems, well jumpers and workover systems for well interventions. A full set of ROV tools is also part of the delivery.

The Mobim and Bilondo structures will be developed with two seabed templates, tied back to a Total-operated FPU. A 19 miles (30 km) export line will carry the oil to Djéno, Emerauda. The projects’ main technological challenge is the thermal performance. The SPS flow assurance issues are low production temperatures, high WAT of 86 F (30 C), potential for hydrate formation and cold gas injected into manifold and tubing hanger.

Moho Bilondo was due to come onstream in April 2008.
