UPI provided FEED, detailed engineering and design, subsea support, project management, and survey services for the 167-mile mainline gas pipeline project, which included both onshore and offshore scopes of work.

The onshore scope consisted of 153 miles of 42 and 48-inch pipeline from a compressor station near Agua Dulce, Texas, south to a compressor station near Brownsville, Texas

The offshore scope consisted of 14 miles of 42-inch pipeline from Brownsville, Texas to an offshore hub in the Gulf of Mexico.
This pipeline connects in the Gulf of Mexico with Mexico-owned Sur de Texas-Tuxpan Pipeline, creating the biggest gas pipeline in existence between the two countries.
