The field, which is producing an initial rate of 200 million cubic feet per day of gas, has targeted gas sales of 545 MMcfd. Kasawari will supply feedstock for the Petronas LNG Complex in Bintulu and for the domestic market.
Discovered 2011 about 200 kilometres off the Sarawak coast, the field contains about 10 trillion cubic feet of gas. This main phase of the Kasawari project involves a central processing platform (CPP), and a flare platform and wellhead platform that are both bridge-linked to the CPP.
Gas from the Kasawari field is exported via an 81-kilometre pipeline to a new riser platform at the existing E11 production hub for onward transportation to Bintulu, Sarawak.
Malaysia Marine and Heavy Engineering (MMHE) fabricated the 53,893-tonne Kasawari CPP, Malaysia’s heaviest-ever offshore structure, at its Pasir Gudang yard in Johor, southern Malaysia. Other structures for the project were built by OceanMight in Kuching, Sarawak.
“Kasawari is a testament to our local capabilities in executing large-scale projects,” commented Petronas Malaysia Petroleum Management senior vice president, Bacho Pilong.
“This accomplishment, involving more than 450 local subcontractors and vendors, was achieved within 26.6 million manhours.”
MMHE also secured the engineering, procurement, construction, installation and commissioning contract for the Kasawari carbon capture and storage (CCS) project — Kasawari phase two.
Kasawari phase two centres on a fixed CCS platform — with a 15,000-tonne eight-leg jacket and topsides weighing 14,000 tonnes — that will be installed in a water depth of 108 metres.
This structure will be bridge-linked to the CPP, with a new 138-kilometre, 16-inch subsea pipeline delivering the compressed CO2 for injection at a depleted reservoir at the M1 field.
US contractor McDermott International won the key installation and subsea pipelaying contract for the Kasawari CCS project, which is now targeting first injection in 2026.
Petronas Carigali has a 90% operated interest in the Block SK 316 production sharing contract and its sole partner is Exploration and Production Malaysia Venture (EPMV).
