Why we watch it
A ~US$5 bn subsea tieback — 16 wells, new risers, flowlines and umbilicals, FPSO modifications — in execution from 2025 towards first oil around 2030.
Who builds it as stated by the sources
Operator / developerShell Nigeria Exploration and Production Company (SNEPCo)
- Shell (SNEPCo)operator 65% of OML 118; partners Esso E&P Nigeria 20% and Nigerian Agip Exploration 15% (after TotalEnergies' exit, completed November 2025)
- Saipemleader of consortium (with KOA Oil & Gas and AVEON Offshore) for EPCI of risers, flowlines, subsea umbilicals and associated subsea structures; ~US$1 bn total, Saipem share ~US$900 m (Dec 2024)
- TechnipFMCSubsea 2.0 production systems — design and manufacture of subsea trees, manifolds, jumpers, controls and services; 'substantial' award (US$250–500 m), Dec 2024
Key dates as stated by the sources
