For more than 20 years, Indian Register of Shipping (IRS) has offered services for noise and vibration measurement and analysis. This year, Colombo Dockyard PLC in Sri Lanka gave it the contract for the noise and vibration measurement and analysis for six bulk ships.
For the comfort of seafarers, the bulk carriers are being built for a Norwegian owner in accordance with the most recent IMO and ISO specifications. The ships have a four-stroke diesel engine that is supplemented with an electric hybrid system that uses a battery system to provide additional power. The ships are environmentally benign since they emit far fewer emissions than conventional bulk carriers of the same size.
The first in a series of six vessels was delivered on September 21, 2022, and the remaining vessels will be delivered at intervals of four months. These vessels are designed to be environmentally benign, producing fewer emissions per tonne than a typical cargo carrier of the same size.
The IRS has previously worked with Colombo Dockyard on a number of projects, and the yard has expressed appreciation for the excellent work and on-time completion of those projects.
Measurements of noise and vibration are made for the comfort of the crew and passengers. IRS performs vibration measurement and analysis in accordance with standard ISO 6954:2000 and class requirements and noise measurement and analysis in accordance with IMO Resolution MSC.337(91) and class criteria.
Additionally, IRS offers support for minimising excessive vibration and noise. Before building begins, noise and vibration levels for newbuild ships are predicted in order to make any necessary adjustments then.
Mr. DK Gupta, Head of Marine Technical Services said ‘A dedicated team of IRS professionals is regularly engaged in provision of Noise & Vibration Measurement and Analysis for shipyards and shipowners in India and abroad. Seafarer well-being is an important element of consideration for owners and managers and through such services we aim to assist owners to improve seafarer well-being.”
