The Sur de Texas – Tuxpan Pipeline Project is an offshore/onshore natural gas transport system from an interconnection point with the Nueces – Brownsville pipeline near Texas, USA, to delivery locations near Altamira, Tamaulipas (“Altamira”), and Tuxpan, Veracruz (“Tuxpan”) on the Gulf Coast of Mexico. The offshore section is the longest part of the project with ~690 km (~90% of the total length) of pipeline laid on the seabed. The remaining part has been executed onshore with a total length of ~80 km.
Beside the landfall, which has been executed using trenchless drilling technologies, additional HDD crossings have been performed onshore. In fact, one of the key goals of the project is to minimize impact on environmentally sensitive areas like mangroves and coral reefs.
