Vital machinery and equipment are those that are essential to the
safety of the MODU and all personnel on board. They include, but are not
limited to, fire pumps, emergency sources of power, dynamic positioning
systems, remote blowout preventer activation controls, and other operational or
safety systems the sudden failure of which may result in hazardous situations.
This does not include spaces (e.g. the driller's cabin) located on the drill
floor.
