Woodside Energy said its Trion development—described as Mexico’s first deepwater oil project—reached the 50 per cent completion mark at year end, as major infrastructure continued to take shape across multiple fabrication hubs.
In shipyards in Korea and China, two floating facilities are being built for the offshore field in Mexico. Equipment and components are being assembled into large steel blocks for lifting, integration and testing, with the company pointing to ongoing progress across the supply chain.
Trion VP Stephane Drouaud recently visited key construction and fabrication locations and highlighted the commitment of Woodside Energy teams and contractors to safe delivery and quality.
At HD Hyundai Heavy Industries in South Korea, construction of the floating production unit advanced, including the successful float-out of the hull following 14 months of block construction and assembly. During the visit, teams completed the safe installation of the first of three major modules, each weighing close to 6,000 tonnes. The company described the lift-and-mating activity as requiring meticulous planning and close coordination across multiple teams.
The visit also marked a safety milestone of three million working hours without a lost-time injury, achieved during a busy phase of construction.
In China, the COSCO yard is fabricating the floating storage and offloading vessel and the Disconnectable Turret Mooring system. The mooring system is planned to be installed in 2,300 metres of water. The storage unit is designed to hold up to 950,000 barrels of crude oil and operate on station over a 27-year design life.
In Johor Bahru, Malaysia, teams at the OneSubsea manufacturing facility completed the first Xmas tree. The company described the equipment as comprising 49,000 components used to control hydrocarbon flow from subsea wells.
Next for the development is the drilling campaign, with drillship Deepwater Thalassa scheduled to arrive in the field in early March to commence a 24-well drilling and completion program. Trion is a joint venture between Woodside Energy (60%, operator) and Mexican state-owned PEMEX (40%), and is targeting first oil in 2028.
