TC Energy awards Southeast Gateway pipelay to Allseas

TC Energy Corp. last week awarded Allseas Group SA a contract to build the 715-km, 36-in. OD subsea Southeast Gateway natural gas pipeline offshore southeast Mexico. The pipeline will deliver 1.3 bcfd of gas from Tuxpan to Coatzacoalcos and Dos Bocas.

The companies expect pipelay to begin end-2023 to meet a mid-2025 in-service date.

Southeast Gateway is being built as part of an alliance between TC Energy and Mexico’s state electricity utility Comisión Federal de Electricidad (OGJ Online, Aug. 8, 2022).

Allseas also installed TC Energy’s 2.6-bcfd Sur de Texas-Tuxpan offshore pipeline delivering gas produced in Texas to Mexico. Sur de Texas-Tuxpan began operations in 2019.
