There will be no Violent Closing of the Doors.
It is highly prohibited to slam doors on a submarine due to the lack of rest that the crew receives and the challenges that come with trying to get some shut-eye on board. Slamming doors is strictly prohibited for the obvious reason that it has the potential to wake up others who are sleeping nearby.
In addition to this, there is yet another issue to consider. It is often vital to maintain perfect silence in order to avoid being noticed by hostile warships. This implies that producing any form of loud noise, including slamming doors and any other kind, is strictly prohibited under any and all circumstances.
