Noisy machinery operating overnight

[davecttr]

On former Celebrity Century class ships, now with Marella, passengers have noticed that on deck 4 port side outside cabins about half way between the forward and midship staircases machinery is switched on overnight that causes a lot of noise and vibration. I have experienced this myself and it is a grinding noise that transmits through the hull. It starts at about 2am and may go on for an hour or more.

 

What machinery that would only be switched on overnight that could cause this, could it be connected with processing food waste etc. Maybe grinding up all those bones from the galley?

Have you complained to passenger services?

Of course, I was moved and got compensation although I did not ask for it. This was on a transatlantic repositioning so there were spare cabins. however in the main season there are few spare cabins and it would be good to warn potential cruisers of the poorer cabin locations with the correct reason for the disturbance.
