McDermott wins Malaysia subsea EPCI contract from PTTEP

SABAH, September 9, 2025 – McDermott has secured a large subsea engineering, procurement, construction and installation contract from PTTEP for the Block H gasfield expansion offshore Sabah, Malaysia, the company said on Tuesday.

The contract includes a carbon steel pipeline and installation of subsea umbilicals, risers and flowlines for the Alum, Bemban and Permai deepwater fields to supply additional gas to the PFLNG DUA facility.
