Shell contracts long-length steel pipes for offshore T&T gas tieback project

Shell subsidiary BG International has contracted Corinth Pipeworks to supply steel pipes for the block 22 and NCMA-4 (Colibri) gas field development offshore Trinidad and Tobago.

Corinth will manufacture 93 km (58 miles) of 16-inch HFW and LSAW coated linepipe for the pipeline which will export gas from the facilities to the Shell-operated Poinsettia platform in Trinidad’s North Coast Marine Area (NCMA).

Trinidad and Tobago state-owned Heritage Petroleum Company is the other partner.

This will be Corinth’s first offshore project involving supply of pipes in 24-metre (80-foot) lengths. This should lead to a reduction of almost 50% in the number of offshore pipe to pipe welds, the company said, resulting in capex savings and an associated reduction in offshore vessel installation time.

Pipe manufacture and coating will start in Greece later this year, followed by offshore pipelay in 2021.
