Designing the Quiet Vessel: Attention Noise and Vibration on Day One
Owning and operating a quiet boat offers many benefits, from crew comfort and retention to efficient, safe operations. While the benefits are clear, itâs generally not the first line of design and concern for most vessel owners.Noise is a funny thing in the marine world: itâs invisible, it sneaks up on you, and itâs usually not the headline item on a newbuild spec sheet, until youâre standing in the pilothouseâŠ
The Problem with Reducing Underwater Radiated Noise
If the global commercial fleet reduced its speed by 10%, it would reduce underwater radiated noise by 40%, but nothingâs ever that simple.The main thing holding the shipping industry back from reducing its underwater radiated noise (URN) is not a lack of appropriate technology. Itâs argued that many of the technologies being implemented today to reduce fuel consumption also reduce noise. So, the noise reductions could essentially come at no net cost to the shipownerâŠ
ENGINEERING: Inter-Compartment Sound Transmission Regulations and Testing
Complying with International Maritime Organization Resolution MSC.337(91) Noise Level CodeOne of the best things a marine operator can do for its crew or passengers is prioritize their comfort by reducing shipboard noise. Commercial and military marine vessels can be subject to very high noise levels produced by everything from onboard activities to aircraft. At worst, this noise can be hazardousâdisruptively noisy environments can lead to discomfortâŠ
