A significant gas field development in the waters off Brunei Darussalam, led by Petronas, is being advanced to secure long-term regional gas supply, supporting both domestic demand and liquefied natural gas (LNG) exports.

As part of this programme, Petronas has awarded McDermott an EPCIC contract that covers subsea facilities and a gas export line for the development. The award combines engineering and procurement activities with offshore construction, installation, and commissioning responsibilities.

Under the subsea portion of the scope, McDermott will deliver a new production system with associated infrastructure. The work includes control umbilicals, along with riser and flowline systems, designed to tie in six wells to a floating production unit that will process natural gas from the field.

The EPCIC contract also encompasses a gas export pipeline that will route gas from the floating production facilities to Brunei’s LNG infrastructure, providing feed gas to the country’s liquefied natural gas sector.

This latest phase builds on earlier involvement by McDermott on the same project, where the company previously completed front-end engineering design (FEED), optimisation studies, and planning for execution readiness.

Project delivery will be managed from McDermott’s engineering hub in Kuala Lumpur, Malaysia, with further support from teams based in other offices and at project locations.

Mahesh Swaminathan, Senior Vice President, Subsea and Floating Facilities at McDermott, said the transition from FEED work into a full EPCIC award underlines the company’s subsea engineering capabilities in the region and its track record on complex projects. He highlighted the collaborative approach taken with customers to maximise engineering value. He noted that McDermott intends to work closely with PETRONAS Carigali Brunei and its partners to execute the development safely and efficiently.
