Marine Masters has completed the offshore phase of Malaysia’s largest offshore decommissioning and rig-to-reef initiative, dismantling the South Angsi Alpha (SAA) platform operated by Hibiscus Oil & Gas Malaysia Ltd.
Located 130 km off Terengganu, the 4,000-mt four-legged Mobile Offshore Application Barge (MOAB) served as a production platform for over 15 years. Following cessation of operations, the platform’s structure was partially repurposed into an artificial reef, aligning with Malaysia’s sustainability goals.
The complex decommissioning was led by Marine Masters, using a reversed installation method to remove the MOAB and related infrastructure. The jacket was cut at -55 meters LAT and separated for placement on the seabed, forming new marine habitats. Marine Masters also recovered 13 conductors, four support legs, and the Wellhead Access Platform.
To avoid costly heavy lift vessels, the team employed custom lifting systems and developed specialized techniques, including remotely operated underwater cutting (ROV-assisted), diver-operated PVL hand cutting, and streamlined personnel transfer methods. These innovations contributed to a safe, cost-efficient campaign.
The MOAB topside was skidded ashore at Labuan Shipyard, where final dismantling is underway. The ENA WB400 accommodation barge has been demobilized, and transport vessels are returning to port.
“This has been a highly successful campaign with minimal delays and outstanding teamwork,” said Danny Spaans, Founder & Director of Marine Masters. “We thank Hibiscus for their trust and collaboration. Our blend of Oil & Gas and salvage expertise proved essential in delivering this fast-track project.”
The SAA project sets a benchmark for offshore decommissioning in Malaysia. It supports Hibiscus Petroleum’s sustainability vision, transforming retired infrastructure into reef habitats that benefit biodiversity, marine ecosystems, and ecotourism.
