TDI-Brooks Completes 16 Seabed Geotechnical Investigations for Cook Inlet LNG Project in the U.S.

en.Wedoany.com Reported - On October 20, U.S. marine survey company TDI-Brooks announced that it had completed seabed geotechnical investigation work for the Cook Inlet LNG import project in Alaska. The investigation was commissioned by project developer Cook Inlet LNG LLC and used the Neptune N5K cone penetration test system to complete 16 in-situ seabed tests in water depths of 10 to 25 meters. The subsurface soil data obtained will be used to select the mooring and anchoring system for the floating storage and regasification unit.

The investigation was carried out using the local third-party vessel R/V Poseidon, with TDI-Brooks deploying portable cone penetration testing equipment aboard the vessel to conduct the tests. The investigation covered different locations of the proposed mooring facilities, focusing on collecting in-situ mechanical data of the soil beneath the seabed. The project developer will use these data to determine the anchoring design conditions for the floating storage and regasification unit.

The Cook Inlet LNG project plans to import liquefied natural gas through a floating storage and regasification unit and moor it near existing offshore oil and gas infrastructure. The project intends to use the Osprey offshore platform and its existing gas export pipeline to connect to the south-central Alaska natural gas pipeline network, with new construction mainly involving vessel mooring facilities and some connecting pipelines.

The project was accepted into the pre-filing review process of the U.S. Federal Energy Regulatory Commission on June 17, 2026. The project developer plans to begin supplying natural gas in mid-2029 and has submitted multiple environmental and engineering resource reports to regulators in October.
