LNG Canada : A major milestone in our LNG Tank journey: cool-down has begun!
LNG Canada : A major milestone in our LNG Tank journey: cool-down has begun!
⚙️ A high-precision concrete slab
Designed to support the entire tank, the reinforced concrete slab is a key component of the containment system. Its construction required:
• Millimetric planarity to preserve the integrity of the LNG storage
• Phased execution adapted to the site’s complex harsh climatic conditions
• Strict quality control to meet the highest concrete standards
⚙️ A structural concrete wall with a critical dual function
Surrounding the slab, a 46-meter-high post-tensioned reinforced concrete wall (entirely in-house engineered) was progressively built. This massive structure ensures:
✅ Structural support for the dome during and after installation
✅ The containment barrier system imposed by codes and regulations
✅ Resistance to external hazard such as fire or blast,
✅ The post-tensioning works were carried out by Freyssinet, also part of VINCI Construction, whose advanced structural anchoring systems contributed to ensuring the long-term performance and durability of the infrastructure.
⚙️ A reinforced concrete roof (after erection of the steel cupola) to ensure :
✅ support for the top platform and tank accessories
✅ resistance to external hazard such as fire or blast,
Together, the slab, wall and roof form the safety monolithic envelope of a “full containment” tank, built in accordance with the world’s most stringent LNG storage standards.
🗓️ Seamless execution, mastered timelines
This pivotal phase mobilised multiple teams across quality, construction, and scheduling. It was delivered:
• On top of foundations built to millimetric tolerances
• With effective collaboration between trades, ensuring seamless coordination and execution
• Just ahead of the successful dome air-lifting operation
This civil engineering achievement demonstrates Entrepose Contracting’s ability to deliver technically demanding infrastructure that meets the highest standards in safety, sustainability, and performance.
📢 Next up: the spectacular air raising of a 1,540-tonne steel dome, spanning 92 meters. Stay tuned to discover how precision engineering meets innovation in the next stage of the LNG Canada journey

LNG Canada Uzo Ojimadu, MBA, Jordan Keim Eric Priore @freyssinet
Nguyen Trinh leads and involves all the business lines to guarantee performance in terms of quality, health, safety and the environment by uniting the teams, from the field to management, around a strong objective: to anticipate, prevent and protect. The role is above all collective.
“Being a construction director means turning technical challenges into collective achievements.”
On the LNG Canada project, Eric Priore led his teams through extraordinary conditions: extreme cold, snowstorms, complex interfaces, and strict HSE requirements.
