Malaysia’s national upstream company Petronas Carigali is edging nearer to production start-up at the next phase of its Bayan redevelopment project offshore Sarawak.

The project’s mobile offshore production unit (MOPU) is scheduled to start its tow this week from Labuan Shipyard & Engineering for installation on Bayan field sub-block 4Q-21.

The tow and installation, which is expected to take around 12 days to complete, is being supported by four vessels — the Malaysia-flagged Executive Pride and Bridgewater 132 plus the Singapore-flagged Bridgewater 130 and the MP Prowess.

First gas

Upon first gas, Malaysian contractor T7 Global will lease the TSeven Elise MOPU to Petronas Carigali for 10 years through to the end of 2032.

T7 subsidiary Tanjung Offshore Services will also provide the operation and maintenance services to the MOPU for the Bayan project.

China’s Richtech International Engineering built the topsides for the MOPU while compatriot Qingdao Haixi Heavy-Duty Machinery Company built the hull under subcontracts from T7.

The Bayan project is located about 30 kilometres south of the West Acis field on the Balingian production sharing contract.

It comprises the MOPU, which will be bridge-linked to the existing BYR-A riser platform, and a 12.7-kilometre pipeline between the existing BYDP-C and BYR-A facilities.

Four new wells will be drilled from the BYDP-C platform as part of the new project, and modifications and upgrading will be carried out on the existing brownfield infrastructure.
