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.
