LONDON — Sarawak Shell and partner PETRONAS Carigali have taken a final investment decision on the Rosmari-Marjoram gas project offshore/onshore Sarawak, Malaysia.
The deepwater sour gas Rosmari-Marjoram fields were discovered in 2014, 220 km offshore Bintulu. The planned development will include a subsea tieback and an unmanned, remotely operated wellhead platform, powered by 240 solar panels.
Produced gas will be exported to an onshore plant at Bintulu via one of the world’s longest sour wet gas offshore pipelines, extending 207 km. The onshore plant will be connected to the Sarawak grid system, supplied mainly from hydroelectric plants, with diesel generators and batteries used as backup.
This will be Sarawak’s largest onshore construction project since the Bintulu Crude Oil Terminal and Bintulu Integrated Facility in the late 1970s.
Shell expects Rosmari-Marjoram to deliver 800 MMcf/d, with first gas in 2026.
