Fabrication starts on deepwater GoM Trion platform

The HD Hyundai Heavy Industries (HHI) yard in Ulsan, South Korea, has cut first steel for Woodside Energy’s Trion semisubmersible floating production unit (FPU). 

This will be the first deepwater oil production platform to operate offshore Mexico, and it is in 2,500 m water depth and 180 km from the coast.

Woodside awarded HHI the engineering, procurement and construction contract in June 2023. Currently, the Trion development (a joint venture with Pemex - 40%) is more than 15% complete, with first oil targeted in 2008.

HHI says it will build the entire Trion FPU, including the topside and hull, and plans to set sail for Mexico in the first half of 2027.

The Trion development is a joint venture between Woodside (60%) and Pemex (40%).
