Subsea Production System & SURF
13-Well System · SURF · SLB OneSubsea · SaipemSubsea Production System
SLB OneSubsea was awarded the contract for a 13-well Subsea Production System (SPS) for the Kaminho project, including associated equipment and services. The system is designed for two-phase development: Phase 1 targeting the Cameia field and Phase 2 targeting the Golfinho field.
During Phase 1, SLB OneSubsea will deploy a highly configurable subsea production platform with standardized vertical monobore subsea trees, wellheads, and controls systems. This standardized approach reduces complexity, improves reliability, and enables faster installation. The system operates in 1,700 meters of water depth on Block 20/11 in the Kwanza Basin.
SURF Package
The Subsea Umbilicals, Risers and Flowlines (SURF) package is contracted to Saipem as part of a $3.7 billion multi-contract award. The SURF scope includes approximately 30 km of 8-inch and 10-inch subsea flowlines, flexible risers, and umbilicals connecting the seafloor wells to the FPSO Kaminho.
For the offshore installation campaign, Saipem will deploy its FDS (Field Development Ship) vessel, utilizing J-lay pipe installation methodology. The local supply chain provides logistics and fabrication support. Associated subsea structures — including 12 vertical suction anchors (each 170 tonnes, 24 meters tall) and an 80-meter flowline protector — are being fabricated at Saipem's Ambriz yard in Angola.
Gas Reinjection System
A critical subsea design feature is the gas management system. All associated gas produced from the pre-salt reservoirs is fully reinjected into the reservoirs through dedicated injection wells — achieving zero routine flaring. This requires a robust subsea gas handling and injection architecture integrated with the SPS and SURF systems.
Mads Hjelmeland, CEO of SLB OneSubsea, stated: "We are excited for this opportunity to unlock the large potential of the Kaminho project together with TotalEnergies." For the full contract architecture, installation timeline, and production capacity analysis, see our dedicated pages.
