Are high tides, currents, whirlpools, wind, and fog a concern?
Although the tides are quite high in the area (Eastport has a mean tide variation of 18.4 ft., and a maximum tide variation of 20.9 ft.), they do not present an obstacle for either the transit of the ship or safe dockage. The proposed Irving LNG facility in New Brunswick is in an area of higher tides (St. Johns has mean tide variation of 23.1 ft., and a maximum tide variation of 30 ft.). Transit through Head Harbor passage will be with the tides. Currents are not an issue at the proposed pier site, as they are estimated to be less than 5 knots. Currents in Head Harbor passage are also not an issue in transit for the oceangoing vessels that carry LNG. Wind and fog conditions do not appear to be a major issue at the proposed pier. At times of high wind or significant fog, the transit of Head Harbor passage may be limited, and access to the LNG ship by the pilot could also be limited.
