The company’s commercial diving and engineering services are designed for applications in oil and gas installation, repair and maintenance (IRM), emergency pipeline repair solutions (EPRS), hyperbaric welding, rig and ship husbandry, and salvage and pollution control among others.
We operate throughout southern, east and west Africa, with operational bases in Cape Town and Durban in South Africa, as well as Tema in Ghana, Angola, Mozambique and Mauritius.
Commercial diving for pipeline inspection in the offshore industry
OSC Marine Group is a recognised subsea engineering and services provider, serving its clients since 1962. Our pipeline inspection services are an expansion of our technical corrosion inspection services for offshore and topside environments.
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.
Our ROV and diving intervention can be used for subsea cutting technologies. With a variety of sizes and capabilities, ROVs can be used to undertake an array of observation and decommissioning tasks.
