New Ship Noise, Vibration Guidelines from ClassNK

(Press Release)
Friday, July 29, 2011

ClassNK released its new Noise and Vibration Guideline for measuring and evaluating the noise and vibration on ships. The new 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.
“This new Guideline,” says ClassNK Development Department General Manager Toshiyuki Shigemi, “incorporates the results of the latest research on noise and vibration aboard ships, along with the latest developments in international rules and regulations, and we believe that this guideline will be an important tool for shipowners, operators, and shipbuilders in their efforts to more accurately measure and more rationally evaluate the noise and vibration on these vessels.”
The new guideline is divided into two parts: Part A, which covers noise and vibration measurement criteria for accommodation spaces in line with IMO Resolution A.468 (XII), ISO 2923:1996 and ISO 6954:2000; and Part B, which covers vibration measurement criteria for rotating machinery and reciprocating machinery in line with ISO 10816. In order to recognize compliance with the new requirements, ClassNK has established new notations for “Noise and Vibration Comfort” (NVC) and “Mechanical Vibration Awareness” (MVA) which will be affixed to the ship classification characters of vessels that comply with Part A and Part B respectively.
Alongside the release of this new guideline, ClassNK is finalizing amendments to related requirements in its class rules, and plans to begin offering the new notations to vessels beginning this fall.
