In addition to our many other specializations, noise survey and vibration control are the primary and most significant. It has been determined that sustained exposure to the sound levels greater than 90dB (A) can cause deafness and vibration can also have impact on precision of on-board instruments and human health. The noise and vibration control has gained more relevance over time and there has been a rise in the awareness about prevention of permanent damage occurring because of sustained exposure to higher levels of noise and vibration.

Noise Level Surveys

Noise levels are measured in following vessel areas:

  • Control Rooms
  • Workshops
  • Propulsion Machinery
  • Turbocharger
  • Top Propulsion Machinery
  • Reduction Equipment
  • Non-specified Workspaces
  • Accommodation & Other Spaces
  • Mess Room & Cabins
  • Recreation Room
  • Offices & Galleys
  • Navigating Bridge Wings
  • Radar & Chart Room
  • Serveries & Pantries
  • Auxiliary Diesel Engines
  • Turbo Generators

The Code on the limits of noise levels on the board ships intends to provide certain standards as a measure to prevent the occurrence of potentially hazardous noise levels on the board ships. The purpose is also to provide standards for an acceptable environment for seafarers. These standards have been developed to address the well-being of passengers and cargo ships. We at QSafe Instrument Systems Pte Ltd offer full range of sea trial services and diagnostic surveys to resolve the issues relating to on-board noise and vibration. Our main objectives are improvement of passengers’ comfort, enhancement in the performance of the liners and also longevity of the lifetime of the ships.

QSafe Instrument Systems Pte Ltd works in a very systematic and professional way. We first determine the source of noise and vibration which is followed by the detection of the path of transmission. After acquiring all the related information that we require, we apply appropriate methods to reduce noise and vibration. The techniques we use include finite element technique, strain measurement and other techniques depending upon the situation and the requirement.
We provide our expert professional services in Singapore and we have our clientele all over the Asian waters.

IMO Noise Regulations

IMO stands for International Maritime Organization which is an inter-Governmental Maritime Consultative Organization. IMO was established in Geneva in 1984. IMO’s noise regulations are set up to provide guidance to the administration, to guide about the maximum noise exposure limits and to provide international uniformity in relation to these standards. This should be kept in mind that these regulations are for ships in general; the ships differing from the conventional ones might need different consideration and may require more customized solutions. IMO noise regulations also set the compulsory maximum noise level limits for machinery spaces, control rooms, workshops, accommodation and other spaces to be followed on the board ships.
