(offshore-energy.biz) Allseas has completed its offshore pipelay commitments for a 700-kilometer-long natural gas pipeline in Mexico ahead of schedule, for its client TC Energy.
The Southeast Gateway 36-inch natural gas pipeline runs south along the coast from Tuxpan through the Gulf of Mexico to Coatzacoalcos and Dos Bocas.
Allseas delivered the pipeline in 11 months, which included the complex nearshore scope and pre-commissioning of the entire system, under a contract secured in 2022.
Solitaire laid most of the pipeline, with Lorealay and Tog Mor providing first-class support. Pioneering Spirit installed the outstanding nearshore section at Coatzacoalcos, without a stinger. Instead, the hanging stinger transition frame served as a mini stinger, a solution tailored to the shallow water depth, Allseas reported.
Furthermore, the company deployed its automated ultrasonic testing system Dolphin for the work, inspecting more than 57,000 welds.
