Don't forget the whole reason the heavy lift ship was being used was because of badly designed bearings on this cruise ship's azimuth thrusters combined with the local drydock being out of commission because of two cranes collapsing on another cruise ship undergoing repairs at the time. So in just this story we have a maintenance failure (bearings) and two critical failure (cranes) in physical engineering.
