Project Description
Tilbury LNG facility was Canada’s first historical LNG facility that has been provided Liquefied Natural Gas since 1971. Originally, the facility’s purpose was to store LNG to ensure the provision of energy even during high winter demand.
Now, the facility is producing LNG for transportation including for British Columbia Ferries and Seaspan Ferries. As the demand for LNG as a marine fuel grows, the facility is also working with the Vancouver Fraser Port Authority to develop the first ship-to-ship LNG marine refueling service on the west coast of North America. Tilbury LNG facility is also the first in Canada to produce LNG for export to China.
In 2015, the phase 1 of the expansion of Tilbury LNG facility was launched with the construction of a post-tensioned concrete LNG storage tank. This tank is a 46,000 cubic meter LNG storage capacity.
Phase 2 of the expansion will start in 2023 and will also include a huge storage tank construction.

About Post-Tensioning
Implementation of post-tensioning of the Tilbury Phase 1 Expansion LNG storage tank took place in 2015-2016.
The tank is made of a single-shell post-tensioned concrete containment with 2 geometry types of tendons:
- 360° loop horizontal tendons
- U shaped vertical tendons
The post-tensioning system counts 19 strand and is bonded: bare strands injected with cement grout.
