Background:
Norce Offshore operate several ships specializing in subsea engineering.
They recently signed a seven year contract to supply engineering services to
Woodside.
Norce recently took delivery of their latest vessel, the Nor Australis.
It is a DPS2 vessel with ROV and Diving capabilities and will be used to serve
the Australia Pacific region.

At this level the noise is particularly
annoying, creates fatigue and makes communication (face to face and over
