The Solitaire vessel laid most of the pipeline, supported by Lorelay and Tog Mor. The Pioneering Spirit vessel installed the remaining nearshore section at Coatzacoalcos. Instead of a stinger, the vessel’s hanging stinger transition frame served as a "mini' stinger to suit laying in the shallow-water depth.
TC Energy helped Allseas progress validation of its automated ultrasonic testing system Dolphin, which was used to inspect more than 57,000 welds. According to Allseas, Dolphin provides fast and reliable inspection cycles for high-production pipeline construction girth weld inspection.
Southeast Gateway is a strategic collaboration between TC Energy and Mexican state utility CFE, supplying gas to the country’s southeast region. In 2017, Allseas installed the Sur de Texas-Tuxpan pipeline, also in the Gulf of Mexico.
In a separate development, the company has entered a partnership with the recently established Nuclear Energy Maritime Organization (NEMO), which is working to advance the use of nuclear technology in the maritime sector as a cleaner alternative to fossil fuels.
Allseas is investing in R&D to examine the use of nuclear power as a sustainable propulsion solution for offshore vessels.
One concept under review is small modular reactors designed to be inherently "walk-away safe."
