Interesting. Informative links here; if the terminal was in Hayes Dock as per first link it could work. If it was on the eastern side of Molineaux Point as per first link surely the swells frequently coming in through the heads would knock the vessels about like corks and make the safe use of the terminal not viable.

Not to mention, if it is built to the east of the point it would surely require dredging, probably not so good for the existing wall.
