I was Night Boss during this incident. I was in the Cinema prior to commencing work and felt a slight jolt ... barely perceptible. But it's strange how you pick up on any change to normal ship sounds, vibration and general rhythm. I left the Cinema and contacted the switchboard who advised me of the flood in the crew accommodation aft. I immediately headed there and recall that the Crew Accommodation Officer (Paul Stevens??) was dashing around with several Glory Hole Stewards trying to stem the flow of water cascading down the stairwells and the alleyways - using blankets, towels, pillows and anything they could lay their hands on (the water was gushing out of the severed pipes, not seawater - though, unfortunately some of it was raw sewage). Eventually the Engineers isolated the damaged pipes and then the clean up started; using members of the Day Gang and, after 2100, the Night Gang.
