Subsea Inspection, Repair & Maintenance / ROV

Integrated subsea inspection, maintenance and repair (IMR) that protects asset integrity, reduces downtime, and keeps offshore operations moving.

Subsea IMR is a critical element of any asset integrity management programme, helping operators de-risk operations, optimise performance, and extend the service life of offshore infrastructure.

We bring strategy, planning and execution together, delivering end-to-end subsea IMR project management supported by work-class ROV operations and fit-for-purpose subsea tooling.

We provide both planned and reactive inspection and intervention services, helping reduce the likelihood of failures and ensuring long-term integrity across subsea systems.

Subsea assets operate in complex, high-consequence environments where teams must manage:

• Integrity threats such as corrosion, fatigue and mechanical damage
• Access constraints in hard-to-reach areas including the splash zone and congested subsea layouts
• External interactions from seabed mobility, fishing activity and vessel contact
• Unplanned failures where rapid mobilisation is essential to restore integrity and reduce downtime
• The need to balance cost, safety and schedule while maintaining production continuity.

Our subsea inspection, maintenance and repair (IMR) solutions

We deliver integrated subsea IMR solutions tailored to your asset and operating context, bringing together offshore delivery discipline and the experienced marine team added through Ross Offshore joining AGR, alongside carefully selected equipment selected for each scope.

Inspection services

• Pipeline inspection
• Hull and mooring inspections
• Cathodic protection inspection and monitoring
• ROV-enabled monitoring and evaluation of subsea asset health

Maintenance and repair solutions

• Planned and reactive maintenance to reduce failure likelihood
• ROV-enabled interventions, corrosion monitoring and structural repairs
• Stabilisation solutions to mitigate risk from seabed movement and third-party interaction

Offshore execution capability

Work-class ROVs equipped with specialised tools provide critical access to subsea infrastructure—even in hard-to-reach areas—enabling efficient inspection and intervention with strong operational control.

In the event of unexpected failures, our rapid-response teams can mobilise quickly to restore operational integrity and minimise downtime. Clients benefit from a single point of contact, access to fit-for-purpose assets and tailored equipment, and a team with deep operational experience.

We deploy the DP vessel M/V Ross Eagle to support demanding subsea IMR operations, including ROV-enabled inspection and intervention. This provides an execution-ready offshore platform that helps keep IMR delivery safe, efficient, and controlled.

Turnkey asset integrity management support

Our IMR capability is further strengthened through our sister companies at ABL Group. ABL supports asset integrity through capabilities including process safety management, inventory and data optimisation, personnel competency and training, and software solutions. Longitude supports owners and operators in optimising asset service life and enhancing operational performance from the outset.
