Article says crankcase explosion on one of six main engines.
BS one engine out of six and they could not even keep beer cold
Obviously you have NO idea what you are talking about.
A crankcase explosion - usually caused by a hot main bearing igniting the oil mist inside the crankcase -can be a huge explosion - causing a fire, which can then destroyed the engine room where all the wiring, switchboards, and motor controllers are.
One does have to ask if the oil mist detectors were working or not.
I wonder what type of engines they have.
Just my experience of 20 years sailing as a Chief Engineer.
