Techint completes Southeast Gateway Pipeline Veracruz Norte in Mexico
Techint Engineering & Construction successfully completed the Southeast Gateway Pipeline Veracruz Norte (SGP VZN) project for TC Energy. The project included a 94,000 HP gas compression station, a 12.4-mile (20 km) 36-inch pipeline, and a record-breaking landfall connection in Tuxpan, Veracruz.
Techint E&C installed a landfall for the first time in its history by inserting 1,915 metres (1.19 miles) of 36-inch pipeline into a 56-inch casing tunnel. The drilling was performed using Direct Pipe® technology over a length of 1,374 metres (0.85 miles). This tunnel is considered one of the longest in the world executed with this technology and diameter, surpassing the previous record of 1,100 metres for a 56-inch pipe. At its peak, the project required over 1,500 people to work simultaneously and in coordination across the three main work fronts, including direct and subcontracted personnel. This represented over 3 million construction hours and 150,000 hours of detailed engineering.
The project enables natural gas to flow from the Monte Grande Metering and Regulation Station through an onshore pipeline and compression station to an offshore section. This supplies gas to southeastern Mexico and supports the region’s industrial activity.
