01 — About onesubsea.cd

We make deepwater simple, safe & profitable

OneSubsea CD is the Congolese hub for subsea production excellence. We combine global SPS engineering with local fabrication, vessels and talent in Pointe-Noire and Muanda. Our mission: unlock Congo Basin reserves with the lowest carbon per barrel in Africa.

From concept to first oil in record time

We own the full stack: front-end engineering, trees, manifolds, jumpers, umbilicals, installation vessels, commissioning and 25-year IMR. No handovers, no gaps.

✓Local content 62%. Yard in Pointe-Noire, spoolbase, testing pit, hyperbaric chamber and Congolese ROV pilots.
✓Standardized SPS. 10k vertical trees, 4-slot manifolds, all-electric actuators – interchangeable across fields.
✓Energy transition ready. Subsea compression, all-electric, CCS-ready templates and methane monitoring.
✓Safety first. 4.2M man-hours LTI-free, API Q1, ISO 14001 & 45001 certified operations.
