McDermott has secured a significant offshore subsea contract from PTTEP Sabah Oil Limited (PTTEP) for the Block H gas field expansion project offshore Sabah, East Malaysia, covering the Alum, Bemban, and Permai deepwater fields.
The scope includes engineering, procurement, construction, and installation (EPCI) of a carbon steel pipeline, along with the transportation and installation of subsea umbilicals, risers, and flowlines (SURF) components. This new infrastructure will enhance the supply of feed gas to the Petronas Floating Liquefied Natural Gas Dua (PFLNG DUA) facility, which has been operating from Block H’s Rotan and Buluh fields since 2021.
“This award reflects PTTEP’s confidence in McDermott’s ability to deliver complex subsea infrastructure,” said Mahesh Swaminathan, McDermott’s Senior Vice President, Subsea and Floating Facilities. “By leveraging our established subsea engineering expertise and versatile marine construction fleet, we are building on a strong track record with PTTEP. The Block H expansion is a critical step in Malaysia’s energy future, and it further strengthens McDermott’s strategic presence anchored by our Kuala Lumpur hub for global deepwater project delivery.”
Engineering and project management will be led by McDermott’s Subsea and Floating Facilities team in Kuala Lumpur, with offshore installation supported by its marine construction fleet.
Operated by PTTEP alongside partners Petronas Carigali and PT Pertamina Malaysia Exploration Production, the Block H expansion is a key element of Malaysia’s deepwater gas strategy, expected to boost domestic gas supply and support long-term energy security and economic growth.
