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.
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.
