The work supported project developer Cook Inlet LNG LLC, collecting subsurface soil data to inform anchor selection. The study covered different locations within their project site with a scope of 16 CPTs in water depths ranging from 10 to 25 meters. Operations were conducted from the R/V Poseidon, a third-party vessel working in the region, demonstrating TDI-Brooks’ ability to deploy specialized geotechnical equipment aboard locally available vessels.

The Neptune N5K is part of TDI-Brooks’ range of portable toolkits available for deployment worldwide. These systems allow clients to pair regional vessel resources with TDI-Brooks’ equipment and technical expertise, providing flexible support for offshore site investigations and infrastructure projects.
