Audio installed by DJW throughout the submarine gives all the sounds of the submarine, from the snoring of off-shift submariners, to the loud noise of the engine room – complete with being able to feel the rumble of the engine vibrations.

Around 20 of the actual submarine gauges, firing panels, warning lights, depth indicators, and more have been re-animated so that the indicators move and lights change. This involved going into the original electronics of the submarine equipment, and converting it to AV controlled operation.

These effects are triggered by visitors walking through under standard operation, but when a tour is being run by a submariner, or staff member, they can trigger special situations, and a diving scenario. These triggers are well hidden, or use submarine equipment already present.

Everyone knows that there is little spare space on a submarine and DJW found this to be the case – carefully hiding speakers, triggers and source equipment so that it can’t be seen, was a challenge. Doing it successfully means that the visitor is never taken out of the feeling of the real submarine.
