This winter we tackled the intrusive problem of too much noise throughout the ships accommodation when she was under power.
To achieve this, we did two things. We replaced the original engine fire containment box, with a brand new one, that was designed and fabricated from scratch, and we substantially improved the engine room bulkhead structure, including a new door in a different position. Modern, high tech sound absorbing materials were incorporated into both projects.

Work in progress
Happily, as the ship left her winter berth, it was immediately apparent that all the hard work had been very successful!
It is now possible to hold a sensible conversation in the Mess Deck and the Deck House without shouting, when the ship is under power, and for the Cook to concentrate fully on the task without wearing ear defenders.
For the “Teckkies”, we reduced the measured sound level by 7dB (decibels) in the Mess Deck, and 9dB in the Deck House. It doesn’t sound much until you realise that, as far as your ears are concerned, a 3dB reduction, halves the noise.
Now, can we all stop shouting please!
