SHELL’s Malaysian business has awarded the engineering, procurement, and construction (EPC) contract for the offshore platform of its Rosmari-Marjoram gas project to Malaysia Marine and Heavy Engineering (MMHE), an energy industry and marine solutions provider.
Once completed, the platform will be installed at 140 km water depth within the SK318 block, 220 km off the coast of Bintulu, Sarawak, Malaysia. SK318 is operated by Sarawak Shell (SSB), a subsidiary of Shell. The unmanned, offshore platform will be powered using 240 solar panels.
During its 20-year design life, the platform will cater to 800m scf/d of gas, which will be supplied to the Petronas LNG complex in Bintulu. Petronas Carigali (20%) and SSB (80%, operator) are jointly developing the Rosmari-Marjoram gas project and expect gas production to start in 2026. The companies announced they had taken a final investment decision on the project early last month.
The Rosmari and Marjoram deepwater sour gas fields were discovered in 2014. The Rosmari-Marjoram development project will consist of a subsea tie-back, an unmanned well-head platform, a 207 km pipeline leading to shore, and an onshore gas plant at Bintulu.
The gas project will be primarily powered by renewable energy, with the onshore plant to be connected to the Sarawak grid system, which is supplied mainly from hydroelectric panels. Diesel generators and batteries will be used as backup.
