Where do they put all the ships they take there? There do not appear to be barrier islands in that part of the coast, such as there along most of the US Gulf and Atlantic coasts. It's more like the pacific coast, with many fewer natural bays.
It isn’t much, is it? Not even a breakwater. I would guess they anchor them out but I don’t really know. Now, a tanker this size isn’t really designed to spend any time swinging off an anchor chain(s) so the problem, as you point out, might not be all that easily addressed. Their only real option might be a threat to sink her.
