Ocean services provider DeepOcean has been selected to support the decommissioning of subsea infrastructure at oil and gas fields offshore Western Australia, expanding its presence in the Asia-Pacific region.
The 2026 offshore campaign will involve the suspension of subsea trees, removal of flowlines, risers and dynamic umbilicals, and the disconnection and recovery of a turret-mooring buoy (DTM). The project, located in water depths of 300–400 m, will be executed from one of DeepOcean’s regional vessels and managed from its Perth office, reinforcing the company’s operational base in Australia.
“We are honoured that DeepOcean has been entrusted with the delivery of this significant project,” said Colin McGinnis, managing director of DeepOcean’s Asia-Pacific operations. “It builds on our extensive regional and international experience in decommissioning and reinforces our long-term commitment to supporting the energy sector in Australia.”
The contract marks DeepOcean’s first major decommissioning award in Australia since its acquisition of Shelf Subsea earlier this year. That acquisition strengthened DeepOcean’s subsea capabilities across the Asia-Pacific and Middle East, combining Shelf Subsea’s local expertise with DeepOcean’s established track record in mature basins such as the North Sea.
“DeepOcean is already one of the market leaders within subsea decommissioning in the North Sea region,” McGinnis added. “This project demonstrates that we are successfully integrating Shelf Subsea’s regional knowledge with our decommissioning competence—the end beneficiary being our clients in the region.”
The value of the contract has not been disclosed, but the award underscores DeepOcean’s growing role in global subsea energy transition work, particularly in end-of-life field management and infrastructure removal.
