Caution
Please note well..
There is a set of circumstances where a marine turbine can run to overspeed. If there is a leaking source of methane or propane in the engine room the machine cannot be shut down if the engine is ingesting the gas.
The liquid fuel can be stopped but it will run to destruction. This could be said of any engine that burns hydrocarbons, and I guess ships have ducted air intakes from the decks. However...this scenario has happened recently.
So if you have any liquified gas anywhere on the ship make absolutely certain it is secure. It is heavier than air and will collect into the lowest part of the ship.
Wait one..."gas detection" Yes Yes this is the danger..I see they are well on top. The BP rig was not so lucky. The machines could not be shutdown.
