Subsea7, OneSubsea take on multimillion-dollar job at ExxonMobil’s Angolan oil project
What happened
Subsea7 and SLB OneSubsea (Subsea Integration Alliance) won a substantial EPCI contract for ExxonMobil’s Block 15 Likembe redevelopment in Angola. The award covers integrated engineering, procurement, construction and installation, and includes umbilical scope executed by OneSubsea from Norway, showing an end-to-end supplier delivery model. Watch whether integrated alliances push for longer bid-validity, mobilisation SLAs or single-point commercial terms in other regions, including APAC
Buyer takeaway
Treat integrated EPCI offers as a real change in commercial posture: single suppliers may demand bundled pricing, conditional mobilisation SLAs and limited bid validity
Cost / money
Directional upward pressure on mobilisation and coordination costs when suppliers bundle scopes, because buyers lose ability to split vessel and subsea-tooling spend across vendors
Supplier / commercial
Expect suppliers to propose single-point liability and integrated warranties, which reduces buyer negotiation levers on specific scope pricing and pass-throughs
Safety / operations
Integrated delivery can simplify HSE alignment but also compress handover points; buyers should demand clear demarcation of safety responsibilities across the integrated chain
What to watch
Watch for suppliers to condition lower headline prices on restrictive bid validity, mobilisation penalties, or integrated SLAs that lock buyers into a single delivery path
