Noise Level Survey on Board Ships and Adverse Effect

ABNORMAL NOISE LEVELS ON BOARD SHIPS AND ADVERSE EFFECT ON SEAFARERS HEALTH & SAFETY

We, Constellation Marine Services LLC as independent ship and marine surveyors do attend nominations from various clients to carry out the Noise Level survey. Recently we got a nomination from one of our clients to carry out the Noise level survey onboard an Anchor Handling Tug. Our Naval Architect/Marine Surveyor upon receipt of the instruction, arranged to attend an inspection onboard the subject vessel.

BACKGROUND
The purpose of noise level survey onboard ships is to provide a safe working condition by taking into consideration the need for verbal communication and to attend to audible alarms. Also to provide an environment where decisions on clear-heard instructions could be made at control stations, navigation bridges, radio room, and manned machinery spaces (Ex. Engine Control Room).
