Subsea7, OneSubsea take on multimillion-dollar job at ExxonMobil’s Angolan oil project
What happened
Subsea7 and SLB OneSubsea’s Subsea Integration Alliance won a substantial EPCI scope at ExxonMobil’s Block 15 Likembe project. The award concentrates engineering, procurement, construction and installation responsibilities across integrated teams operating from multiple regional centres, making mobilisation and long‑lead coordination operationally real. Watch whether follow‑on sequencing and supplier slotting lead to short mobilisation windows or tightened availability commitments
Buyer takeaway
Treat this award as a real concentration of demand: mobilisation and long‑lead items are now likely controlled by a small number of integrated suppliers, reducing buyer flexibility
Cost / money
Directional upward pressure on mobilisation and scheduling premiums is likely because integrated suppliers can internalise more scope and reduce spot‑market requirements
Supplier / commercial
Suppliers with control of umbilicals, installation vessels and specialised crews gain pricing and timing leverage; availability commitments become a key negotiation point
Safety / operations
Integrated offshore installation demands harmonised HSE across geographies and verified lift and handling plans to avoid cross‑contract stop work situations
What to watch
Watch for suppliers shortening quote validity and inserting mobilisation triggers or demurrage pass‑through clauses as they manage their fleet slots
Key facts
- Integrated EPCI award for Block 15 Likembe project
- Execution split across Subsea7 offices and SLB OneSubsea centres
- Integrated delivery model centralises umbilical and installation scopes
