Ksi Lisims LNG
SECTOR: Marine Nearshore – LNG Export Facility
LOCATION: british columbia, canada
DATE: 2024
EQUIPMENT: long stroke sonic drill rig, multidrill rotary rig, in-situ testing tools, marine barge platform
ConeTec conducted a site investigation for the Ksi Lisims LNG project, a proposed floating LNG export facility on Nisga’a Nation land near Gingolx, British Columbia. Using a custom CPT deployment system, ConeTec efficiently profiled soft sediments at deepwater locations, overcoming challenges such as 7-meter tidal swings, remote boat access, and water depths over 100 meters to deliver essential data for the project’s development.
