Client: Bechtel (owner Petronas)
Location: Pacific Northwest LNG site, Prince Rupert, British Columbia
Drill Rigs Committed: 2
Geotech participated with partner, Gregg Drilling and Testing Canada, on a near and off shore geotechnical investigation drill program for the Pacific Northwest LNG project off Lelu Island in Prince Rupert, British Columbia.
Extreme wind, off shore winter weather, and protestors presented challenges throughout this program. The turbulent water caused challenges while drilling when there is a need for precision and accuracy while drilling for geotechnical purposes. Although weather frequently resulted in standby, the drill crews were able to approximately double their anticipated production rate while actively drilling, assisting with monitoring program timelines.
Ongoing protestor activity attempting to provoke our crews to react for media attention. Throughout these attempts the drill crew remained professional, while completing their duties responsible and effectively.
Geotech completed multiple mud rotary near shore boreholes, ranging from 30 meters to 140 meters in water depths of up to 30 meters. This program involved a Fraste MDXL drill rig, seacans, anchor winches and ancillary equipment on a 50 m by 15m barge which required significant specialized revisions to satisfy the requirements of the project.
