Thanks for your comment Red, I was thinking that would be the case. But could it ‘hole’ a container ship and cause it to sink?
What about a tanker, or small warship?
Hi Ray, overall I don't think (and am not aware of) containers causing such damage to larger ships. Been a long time since I was on container vessels but the steel on containers is only 3mm thick (if I remember rightly. Only the 4 corner posts are structural/load bearing and of heavier gauge. An empty container is only about 3t weight.
So most larger ships would probably suffer paint scuffing at worst - the hull plating of the ships I was on was about 10mm thick, coupled with the structural framing so fairly strong. But smaller warships (such as those involved with mine clearance) can be of glass fibre construction and I would strongly suspect that a container could likely cause serious damage to such vessels.
The biggest risk is to sailing/power recreational vessels. Whilst never proved to be the cause, a partially submerged container was believed to be the cause of the flooding and sinking of the Irish tall ship sail training vessel "Asgard II" about 10 years ago in the Bay of Biscay, thankfully with no loss of life. Asgard II was a timber hulled vessel.
