Offshore Maritime Services (OMS) is a South African marine logistics and support vessel operator, primarily recognized for its role in the Off Port Limits (OPL) sector. Based in Cape Town with operations extending to Gqeberha (formerly Port Elizabeth), the company serves the high volume of international shipping traffic passing the Cape of Good Hope. Rather than requiring vessels to enter the harbor—a process that incurs significant port dues and time delays—OMS facilitates the transfer of personnel and supplies while ships remain at sea, maintaining the momentum of global trade routes.
Established with a focus on maritime logistics, the organization has operated in South African waters for over two decades. Its core mandate involves providing a lifeline to passing merchant vessels, tankers, and offshore installations. The company coordinates complex logistics that bridge land and sea, managing the transportation of crew members, surveyors, and technicians from airports or hotels directly to vessels waiting offshore. Beyond personnel transfers, the company handles the delivery of essential ship stores, spare parts, and provisions, as well as the removal of waste and equipment for repair.
To execute these operations, Offshore Maritime Services utilizes a fleet of purpose-built launch vessels designed to withstand the often turbulent sea conditions characteristic of the South African coastline. These vessels are engineered for speed and stability, allowing for safe transfer operations even in adverse weather. The fleet includes custom-designed craft capable of carrying substantial deck cargo, supporting not only standard resupply missions but also more demanding maritime projects such as diving support, towage assistance, and salvage operations.
The company also plays a role in the broader energy and offshore support sectors. While its primary volume comes from transient commercial shipping, OMS has historically provided support to oil and gas rigs and other offshore infrastructure. By maintaining 24-hour readiness and a dedicated launch base, the company acts as a critical service node in the Southern African maritime corridor, ensuring that vessels traversing this strategic choke point receive necessary logistical support without deviating from their voyages.
