Indian Register of Shipping (IRS) has successfully completed noise and vibration measurement and analysis for five offshore patrol vessels built at Goa Shipyard Ltd (GSL) for the Indian Coast Guard. IRS’ Marine Technical Services (MTS) are recognised for accurate data acquisition and in-depth analysis. GSL has appreciated IRS for continuous support and timely completion of the project despite challenges caused by the global pandemic.

Noise and vibration measurement are carried out to ascertain compliance with crew and passenger comfort requirements. These requirements are verified as per MLC Code – Regulation 4.3 & Para B.4.3.2, which deals with preventing the risk of exposure to hazardous levels of noise and vibration on board ships, and to provide an acceptable occupational and onboard living environment for seafarers.

Established in-house procedures are followed for noise measurement and analysis as per SOLAS II-1/3-12, and for vibration measurement and analysis as per standard ISO 20283-5 and customer specifications.

IRS has performed Noise and Vibration analysis for more than 200 vessels including: Indian Coast Guard vessels, Passenger vessels, Cement Carriers, Oceanographic vessels, Diving Support Vessel and variety of support vessels.

Mr Dileep Gupta, Head of Marine Technical Services at IRS, said: “In addition to noise and vibration measurement and analysis, IRS provides technical assistance to resolve this potential problem. IRS has also developed special software tools to predict noise and vibration levels, for newbuild ships at design stage itself.”
