Canaport LNG Multi-Purpose Pier Structural Survey
Managing an above- and below-water survey of a pier built for the world's largest LNG carriers.
Commercial divers, structural engineers, winter weather and Bay of Fundy currents, managed to an acceptable impact on budget and schedule.
The deep-water multi-purpose pier at the Canaport LNG regasification terminal, now operated as Saint John LNG, receives Q-Max vessels, the largest liquefied natural gas carriers in the world. Mooring dolphins, berthing dolphins, catwalks and a main platform sit on concrete decks supported by steel-framed metal jackets connected to piles in the seabed.
A five-year check-up
An above-water and underwater survey must be completed every five years to confirm the pier is structurally safe. We managed the survey, subcontracting and coordinating a crew of commercial divers, dive support personnel and structural engineers.
Working with the Bay
The underwater work faced inclement winter weather and the Bay of Fundy’s strong tidal currents, which limited the time available each day. Overall, the project was delivered with an acceptable level of impact on budget and schedule.
