Integrated subsea IRM services

Our IRM offering covers the full lifecycle of subsea asset care - from initial installation, baseline inspections and structural assessments through to complex repair, recovery, post-repair verification and decommissioning. We work across both shallow and deepwater environments, tailoring each campaign to project and region.

Our in-house equipment and project management expertise allow us to move quickly and deliver consistently - even in challenging locations.

Our core capabilities include:

Inspection

Visual acoustic and ROV-based surveys
NDT (non-destructive testing) and CP readings
Baseline and in-service integrity inspections
Digital inspection planning and reporting

Repair

Diver and ROV-assisted repair work
Structural clamp and tie-in installation and repair
Hose, cable and pipeline repair

Maintenance

Cleaning, de-burial and marine growth removal
Coating and corrosion protection
Mattress re-stabilisation and debris clearance
Long-term maintenance strategy and support

Smart tools. Skilled teams. Reliable delivery.

Every IRM campaign is different. That’s why we build flexibility into our delivery - from the way we design scopes to how we deploy assets and personnel. Our projects are led by experienced IRM oil and gas project managers, supported by in-house subject matter experts and delivered by proven offshore teams.

We deliver projects with our own dedicated personnel and fleet of subsea tooling, diving and ROV spreads across key regions. This means faster mobilisation and fewer delays offshore.

Where possible, we work to reduce repeat site visits and compress timelines - helping customers save cost and reduce asset disruption.
