0 Offshore Support Vessel (OSV) Seafarer Jobs

Offshore Support Vessels (OSVs) are critical assets in the offshore oil, gas, and renewable energy industries. These vessels perform a wide range of support tasks, including the transportation of personnel, equipment, fuel, water, and chemicals; platform resupply; anchor handling; towing; and emergency response. OSVs are often equipped with Dynamic Positioning (DP), specialized cargo systems, cranes, and deck space to carry modular equipment. Operating in demanding environments, OSVs require a capable, safety-oriented crew experienced in marine and offshore logistics.
