13.1 Incorporation of noise recovery areas may
be used as an alternative design approach for the construction of
ships under 1,600 GT or ice-breaking vessels. Noise recovery areas
may also be considered for incorporation in ship-specific applications
where noisy operations (examples are extended air/helicopter operations
or heavy weather operation of dynamic positioning equipment) are undertaken
for time periods over and above those of normal, routine seagoing
practices. The use of these spaces should be integrated into ship
safe operations policies under the ISM Code.
13.2 Noise recovery areas should be provided if
no other technical or organizational solutions are feasible to reduce
excessive noise from sound sources.
