Challenge
Prepare a major LNG terminal for expansion with geotechnical construction and ground improvement services
Our client’s goals included expanding an LNG terminal for three LNG trains, a common gas pre-treatment unit, and a dock. Before construction could begin, the ground needed improvement to support the complete turnkey natural gas liquefaction facility.
ENTACT’s ground improvement expertise meant a successful solution for our client, and a project that was completed under budget and ahead of schedule.
ENTACT Solution
Prior to stabilizing, we cleared and grubbed the site, constructed board access roads, and performed stabilization pilot tests to confirm correct soil solutions. Our in-house soil geotechnical and stabilization expertise enabled us to be nimble in finding the right solution and helping maintain project timelines.
Having our company-owned equipment ready to work for our client was key for reaching productivity objectives. In addition, our experienced crew met every challenge, including constructing a pneumatic system and custom-made conveyance boxes to deliver cement for ground improvement activities.
