Subsea IMR (Inspection, Maintenance, Repair)

Subsea IRM (Inspection, Repair, Maintenance) is a critical service for ensuring the integrity, safety, and operational performance of offshore assets. Our comprehensive subsea integrity management approach combines advanced inspection technologies, diver expertise, and ROV capabilities to deliver reliable solutions for pipelines, risers, manifolds, SPM systems, offshore platforms, subsea structures, mooring chains, and umbilicals.

Inspection Services

Subsea IRM begins with thorough offshore inspections to assess the condition of your subsea assets. This includes:

• Diver inspection for hands-on evaluation of structural conditions

• ROV inspection for hard-to-reach or deepwater areas

• NDT testing to detect flaws, corrosion, or material fatigue

• Pipeline inspection, riser inspection, and SPM maintenance checks

• Corrosion monitoring and structural assessment to detect early signs of degradation

• Seabed surveys and CCTV recording for precise documentation

These inspection campaigns provide a detailed understanding of the asset’s condition and help prioritize maintenance and repair activities while adhering to IMCA standards and HSE compliance.

Repair Services

When defects or damage are identified, we seamlessly transition into subsea repair operations, including:

• Leak repair and clamp installation

• Subsea welding and structural reinforcement

• Hose replacement and anode retrofit

• Coating restoration to protect against environmental wear

Our repair procedures are performed by certified divers and skilled ROV operators, ensuring all corrective actions meet offshore asset integrity requirements and client specifications.

Maintenance & Preventive Services

To maximize asset lifespan, we implement both preventive and corrective maintenance strategies, including:

• Marine growth removal to prevent fouling

• Cathodic protection monitoring and adjustments

• Bolt torqueing and valve operation testing

• Routine subsea integrity management and condition-based maintenance

These measures reduce operational downtime, prevent costly failures, and ensure that offshore assets continue to operate safely and efficiently.
