is to determine at the design stage the
noise levels to be expected in all relevant
areas. If excessive noise levels are
predicted, decisions can be made on the
necessary noise reducing measures.
In the noise
prediction, a calculation model is prepared
comprising main noise sources, noise
transmission in the ship hull, and noise
radiation in the receiving spaces. Air-borne
as well as structure-borne noise is
ship noise sources are introduced in the
calculation model - propellers, gearboxes,
engines, exhaust systems, fans etc.
reducing measures such as resilient
mountings, floating floors, sound insulation
etc. can be simulated in order to evaluate
the dB(A) noise reduction for various
consideration behind our noise prediction
services is that noise problems may be
solved effectively with small or moderate
cost implications during the design stage.
Problems found on the sea trials may be much
more difficult to rectify.
to noise onboard, also external noise
(radiated e.g. into harbour areas) can be
predicted and reduced if necessary. This is
increasingly important for a number of
owners and operators.
