The US offshore energy contractor Allseas has announced the completion of its offshore pipelay commitments for the Southeast Gateway natural gas pipeline project in Southeast Mexico. The 700 km-long natural gas pipeline project runs along the coast off the Gulf of Mexico from the Mexican ports of Tuxpan to Coatzacoalcos and Dos Bocas, and it is expected to supply natural gas to Mexico’s central and southeast regions and consolidate the existing Transportadora de Gas Natural de la Huasteca (TGNH) assets including the Tamazunchale (370 km, 825 mcf/d or 8.5 bcm/year between Naranjos and Tamazunchale and 630 mcf/d or 6.5 bcm/year between Tamazunchale and El Sauz), Tula-Villa de Reyes (420 km, 886 mcf/d or 9.2 bcm/year), and Tuxpan-Tula (276 km, 886 mcf/d or 9.2 bcm/year) pipelines.
The project is being developed by the Canadian energy infrastructure group TC Energy in partnership with the Mexican state-owned utility CFE (Comisión Federal de Electricidad) and it should have a 1.3 tcf/d (13.4 bcm/year) capacity once it becomes operational by 2025.
