A consortium of Boskalis and Allseas has been awarded a contract by CPC Corporation Taiwan for the second offshore gas pipeline from Yongan to Tongxiao.
The total contract value is approximately €1.2bn ($1.39). This project is intended to improve the gas supply capacity in northern Taiwan.
Under the contract, the consortium will design, construct, install, and pre-commission the new 36-inch offshore natural gas pipeline, which will run approximately 232 km parallel to the existing YT1 pipeline, connecting the Yongan LNG terminal in the Southwest with the Tongxiao transfer station in the northwest.
The comprehensive scope of work includes trenching, pipeline installation with 34 crossings over existing and future infrastructure and assets, backfilling, and two landfalls.
Boskalis will be responsible for the landfalls and associated microtunnelling activities, as well as nearshore and offshore trenching, backfilling, and the installation of rocks for the crossings. For these activities, Boskalis will deploy two large hopper dredgers, a large backhoe dredger, and a subsea rock installation vessel.
Allseas will carry out the pipeline installation and pre-commissioning, including the pre-lay installation of concrete mattresses. According to a statement from the companies, Allseas will deploy two of the most advanced pipelay vessels in the industry to this project.
Project execution is scheduled to commence in 2026, with completion anticipated in 2028.
