(P&GJ) — A Boskalis–Allseas consortium has secured a $1.3 billion contract from CPC Corporation Taiwan to construct the second offshore natural gas pipeline connecting Yongan to Tongxiao (YT2). The project is aimed at bolstering natural gas supply to northern Taiwan and supporting the nation’s energy transition.
The 36-inch pipeline will span approximately 232 kilometers (144 miles), running parallel to the existing YT1 pipeline between the Yongan LNG terminal in the southwest and the Tongxiao transfer station in the northwest. The scope includes trenching, installation across 34 infrastructure crossings, backfilling, and two landfalls.
Boskalis will handle landfalls, microtunneling, trenching, backfilling, and rock installation for the crossings, deploying large hopper dredgers, a backhoe dredger, and a subsea rock installation vessel. Allseas will manage pipelaying and pre-commissioning, including concrete mattress installation, using two advanced pipelay vessels.
“This landmark energy project is intended to support the acceleration of energy transition in Taiwan and improve the gas supply capacity in northern Taiwan,” the companies said in a joint statement.
Construction is expected to begin in 2026 and finish in 2028.
