OSC Marine Group carries out a range of salvage and pollution removal for the offshore industry.

The majority of pipeline-related incidents occur due to metal loss, which can be caused by corrosion, cracking and incorrect pipe grade or poor joints.

OSC Marine Group collaborated with LIN SCAN to offer the capability to inspect and maintain liquid and gas pipelines in adverse environments.

Maintenance and repair activities should have minimal surface preparation and shutdown time for optimal cost-effectiveness. Our certification and training programmes for application technicians can be made according to client requirements, including pipeline integrity, pipeline subsea leak detection and emergency pipeline response.

Commercial diving and hyperbaric welding

OSC Marine Group offers specialist hyperbaric welding services for steel and high-density polyethylene (HDPE) pipelines.

Our engineering team has more than 25 years of hyperbaric design and operational experience.

Offshore topside inspection services

OSC Marine Group’s topside inspection services are part of the technical corrosion inspection offering for offshore environments.

Upstream and midstream oil and gas installations experience some of the most adverse working conditions. Our risk management systems ensure that we can work in these environments using compliant equipment and expert personnel.

Ranging from inspecting oil storage tanks at heights of more than 100m on stacks, jack-up rigs and flare towers, access to critical offshore components are made difficult and costly due to high safety standards within the industry.

We can assemble and mobilise personnel for the oil and gas sector, making it a viable solution to safe maintenance at high and difficult to access positions.

Remote operated vehicles and pilot training for offshore operations

As a recognised underwater specialist, we have provided services for multiple offshore applications. This includes remotely operated vehicle (ROV) supply, skilled pilots with engineering backgrounds, repairs, maintenance, and bespoke ROV pilot training.

Seaeye Falcon and Falcon DR is our powerful, portable and versatile ROV solution. It is designed for coastal and inshore operations, as well as flyaway operations offshore.

Seaeye Tiger and Lynx are widely regarded as leading observation and inspection vehicles within the oil and gas industry while the Seaeye Cougar XT is a compact, powerful electric ROV with working depths of 2,000m.

This system is designed to accommodate heavy-duty tooling with a system of quick-change tool skids that make it ideal for survey work, drill support, light construction and salvage support.

All of our ROVs are available with a variety of optional tools and accessories.

Commercial diving for the oil and gas industry

OSC Marine Group offers a range of commercial diving services, including IRM, construction support, decommissioning support and specialised repair services.
