I hadn't seen the news this morning. Now I have and I can't say I'm surprised. Large container ship loses propulsion power near bridge which means you have no control. Huge number of boxes on deck so a lot of windage. To steer at all this kind of ship needs to go relatively fast so when they lose power theyve got no control at all. Slide into a bridge support which had no protective barriers and that's going to be it. At close to 100,000 tonnes and travelling even as slow as 5 knots that's an awful lot of kinetic energy getting instantly transferred to the bridge structure.
I'm a bit twitchy at the moment as we have 2 bridges to negotiate where the clearance is barely a metre. Hoping our calculations are correct!
