🔒 LNG Canada – Tank closed and ready for interting Following the acceptance of the hydrostatic and pneumatic tests, the LNG Canada project reached a key milestone: the closure of the tank and inerting with nitrogen. This sequence marks the end of heavy work on the tank and the transition to the commissioning phase. 🧰 […]

LNG Canada # STEP7 _Hydrostatic and pneumatic tests: reliability confirmed

Aerial view of a circular tank foundation under construction, with cranes, formwork, and materials arranged around the concrete base within an active industrial site.

Before the cryogenic tank could enter service, a critical verification was successfully completed: the hydrostatic and pneumatic tests of the tank. The main purpose to hydrotest a LNG tank is to verify the primary containment’s tightness and confirm the structural integrity of the foundation under full load conditions while the pneumatic test ensures the tank […]

LNG Canada – A monumental civil structure for the largest cryogenic tank in North America

Aerial view of a large circular industrial tank under construction, with reinforcement steel, workers, and two cranes, set within a wide construction site surrounded by roads, equipment, and forested mountains.

Following the installation of the innovative foundation system for the main LNG Canada tank, executed by Soletanche Bachy Canada, expert in foundations and soil technologies and subsidiary of VINCI Construction, the teams at Entrepose Contracting and VINCI Construction Grands Projets began work on a full-containment, in-house engineered, civil concrete monolithic structure to meet the formidable […]

LNG Canada #Stage 6– LNG primary containment : the cryogenic heart of the tank takes shape

Large circular concrete storage tank under construction, surrounded by cranes, scaffolding, and construction equipment, with forested mountains in the background.

Following the successful installation of the suspended deck, the LNG Canada project has reached another major breakthrough with the construction of the inner tank shell, the primary containment system for LNG storage. This shell is fabricated entirely from 9% nickel steel material, a high-performance alloy designed to withstand cryogenic temperatures of -162°C. 📍Engineering excellence in […]

LNG Canada #Stage 5 – Suspended Deck as a Key Component for LNG Tank Insulation Performance : modularisation & quality excellence

After installing the process modules, the LNG Canada project team undertook on a strategically timed phase: the cryogenic insulation of the suspended deck The suspended deck, based on Entrepose Contracting in-house design, features an innovative and modular approach aimed at minimizing site installation hours and reducing aluminum welding hazards. Built with precision and subject to […]

LNG Canada #Stage 4 – Modules in place: ready to power the heart of the tank reservoir
