Equinor picks DeepOcean for multi-field subsea projects on NCS
What happened
Equinor awarded DeepOcean a multi-field subsea package covering Visund, Snorre A (option) and Johan Castberg, including SIMOPRO riser replacements and installations using chartered subsea vessels. Operations are scheduled for 2027–2028 and will be executed in 300–400m water depths, making vessel charter and uptime coordination operationally material now. Watch supplier mobilisation windows, charter commitments and safety plans for live‑production riser work
Buyer takeaway
Treat award as a concrete vessel and uptime dependency that should drive early charter checks and mobilisation gating
Cost / money
Expect directional premium pressure on specialist vessel dayrates and mobilisation fees if availability tightens
Supplier / commercial
Suppliers with chartered fleets gain leverage; buyers should demand firm availability commitments and penalties for schedule deviation
Safety / operations
SIMOPRO riser replacements while on production raise coordination and safety planning needs that must be contractually enforced
What to watch
Watch for shortened quote validity and bilateral resource claims as suppliers book vessels across projects
Key facts
- Scope covers Visund, Snorre A (option) and Johan Castberg
- Works include riser replacements and template/umbilical installations
