ClassNK issues a new Noise and Vibration Guideline
For measuring and evaluating the noise and vibration on vessels ClassNK has issued a new Noise and Vibration Guideline for measuring and evaluating the noise and vibration on vessels.The guideline address the growing demand for new standards for noise and vibration on commercial vessels and provides detailed requirements for measuring and evaluating noise and vibrations in crew accommodations and machinery rooms, as well as establishes new notations for ships that comply with the new requirements.As efforts to improve the working conditions of seafarers have come to the forefront over the past several years, vibration and noise in accommodation areas have become an increasingly important topic.At the same time, as awareness of the detrimental effect that vibration can have on the reliability and safety of vessels' machinery and equipment has grown, research is increasingly focused on developing new countermeasures for machinery vibration.With the results of many such research projects just now being released, ClassNK felt the time was ripe to release a new set of standards for the maritime industry."This new Guideline," said ClassNK development department general manager Toshiyuki Shigemi, "incorporates the results of the latest research on noise and vibration on board ships, along with the latest developments in international ...
