This megaproject, in partnership with Pemex, is heading towards its first production in 2028, with 35% accumulated progress at the end of the first half of 2025.
Progress in the Trion oil field
During the first six months of 2025, the development of the floating production unit (FPU) recorded key technical milestones. Detailed design was completed, hull blocks were moved to drydock, and construction of three deck modules and accommodations progressed. In addition, fabrication of critical turbomachinery machinery was completed.
In parallel, the floating floating storage and offloading (FSO) facility (FSO) continues with its advanced engineering and will start fabrication in the second half of the year. Work is also actively underway on the anchoring system and fabrication of the disconnectable turret mooring, along with the anchor piles for FPU and FSO.
Subsea equipment and contracts awarded
The design, procurement and fabrication of subsea systems subsea systems and and gathering lines are in full swing. All subsea trees, control systems and associated equipment have been ordered and are in fabrication.
Woodside awarded all strategic contracts required for the current phase, including drilling and completion services, subsea pipeline installationFSO operations and maintenance, and marine support logistics.
