Omsb - Onslow Marine Support Base

Onslow Marine Support Base (OMSB) is redefining offshore logistics in the Pilbara with a dual-port precinct that combines Beadon Creek and the Port of Ashburton into one coordinated hub. Just 17 km apart, these ports deliver over 600 m of combined berth line, handling vessels up to 150 m LOA | 8 m draft at POA and up to 110 m LOA | 6.5 m draft at Beadon Creek. This unique configuration ensures congestion-free operations and scalability for multi-vessel programs, setting a new standard for efficiency and flexibility in marine-to-land logistics. At OMSB, speed and reliability are built into every service. Round-the-clock residential stevedores, dual LCT ramps, heavy-lift crane pad, and HACCP temperature-controlled storage make fast vessel turnarounds the norm. Integrated warehousing and scalable infrastructure support complex offshore campaigns, while ISO 9001/14001/45001 certifications and Climate Active accreditation demonstrate our commitment to safety, sustainability, and compliance. OMSB also holds DG/NORM licences, ensuring safe handling of hazardous materials. Our facilities will shortly include up to 900 kL fuel and 800 kL water capacity, enabling rapid mobilization for offshore projects. Strategically located near the Northern Carnarvon Basin and the Pilbara Regional Waste Management Facility (PRWMF), OMSB streamlines offshore support, decommissioning logistics, and waste management across the region. Whether it’s priority berthing, deep-water capacity, or integrated supply chain solutions, OMSB is the trusted partner for operators seeking operational excellence in one of Australia’s most critical energy corridors. We’re proud to support the Pilbara’s growth with infrastructure that delivers flexibility, safety, and sustainability, 24/7.
