yep. even a hurricane is going to have a windshear of around 10 or 20 kN on the hollow crane at a rough estimate
a 20000 tonne ship (which is small for a container ship) even at super slow speeds is going to have a point impact of 20000 kN and upwards. hard to design for that unless you've got some magical rubber-like substance.
my uncle was the engineer on ( in the mid 80s) the worlds biggest bulk carrier, they had a fucked autonav system (designed by Decca of record fame) that worked fine at sea but in port piloted them into a collision with the quay a couple of times, to spectacular effect
