Prioritize Remote Inspection and Subsea Options to Reduce Decom Costs

What happened

Advanced subsea inspection technologies and digital twins are being used to produce high-quality, repeatable datasets that let operators detect change and reduce vessel time. Petrobras and others have used diverless/remote inspection campaigns to cut offshore personnel and speed execution, making the approach operationally real for P&A planning. Watch whether these workflows become standard acceptance criteria in tenders and whether onshore data-processing capacity becomes a procurement bottleneck

Why the category manager should care

Prioritise suppliers that can deliver repeatable, high-quality subsea datasets because these reduce vessel time and on-site personnel needs

Key facts

• Millimetric-resolution 3D point clouds from subsea LiDAR cited as repeatable inspection deliv
• Petrobras demonstrated a fully remote inspection campaign with zero offshore personnel

What happened

Subsea processing (boosting, compression, water injection) is moving from niche to practical use, helping operators increase recovery and avoid costly topside modifications. In at least one example a subsea boosting system enabled the decommissioning of one host facility while rerouting production, showing this can directly reduce immediate removal scope. Watch how many operators adopt this as a deliberate strategy to defer decom liabilities

Why the category manager should care

Treat subsea processing as a valid commercial alternative to immediate removal where it meaningfully reduces net decom scope or cost

Key facts

• Over 150 subsea boosting pumps and compressors installed worldwide
• Subsea boosting example cited that offset production equivalent to up to two new wells at peak

What happened

Regional operational updates show vessel redeployments, FLNG movements, and pipeline/asset activity across multiple basins, indicating shifting fleet demand and localized scheduling pressure. Items such as FLNG departures for upgrades and ship redeployments make vessel availability for heavy-lift and removal campaigns more variable in the near term. Watch specific vessel and shipyard bookings that intersect planned P&A windows

Why the category manager should care

Map vessel and yard movements against decom schedules to avoid paying premiums for last-minute rebookings

Key facts

• FLNG vessel departures for upgrade work and redeployment noted across regions
• Multiple operators awarding survey, drilling support and pipeline contracts indicating fleet

What happened

and mooring systems are progressing in maturity with some technology (mooring/power interface) reaching higher technology readiness levels after trials. This makes certain floating-asset removal approaches more feasible, but these technologies still need operational validation in full decom campaigns. Watch for verified TRL evidence and recent trial reports before assuming readiness for large-scale removals

Why the category manager should care

Award preference should go to suppliers with recent, documented trials at relevant TRL levels for floating-asset decom activities

Key facts

• Full-scale inshore trials reported for a mooring/power interface system reaching TRL 7/8
• Technology validation occurred following inshore testing in Scotland
