Tag: noise code

Noise on board ships can cause temporary or permanent hearing loss. It is usually gradual because of prolonged exposure to noise, such as working in an engine room without wearing hearing protection. However, hearing loss is not the only problem; seafarers may develop distressing conditions such as ringing, whistling, buzzing or humming in the ears, which can lead to disturbed sleep.

As ship-owners must ensure their vessels meet strict noise regulations, Tokai University initiated two projects intended to help engineers reduce and control noise on board during operation.

Based on R&D outcomes from a project carried out through ClassNK’s Joint R&D for Industry Program, ClassNK now treats bulkheads and decks including steel plates of a thickness of ≥6mm as having a weighted sound reduction index (Rw) of 35dB, the level required between cabin to cabin by the Code, which will streamline the design and construction process.

Effective from 1st July 2014 The Noise Code 2012 willenters into force on 1 July, 2014, under new SOLAS regulation II-1/3-12.The Hong Kong flag administration has issued Merchant Shipping Information Note regarding requirements for protection against noise for Hong Kong registered ships. The Note contains additional requirements for ships constructed on or after 1 January, 2009, for which the Noise Code 2012 is not mandatory.The additional requirements apply to all Hong Kong registered vessels of 1,600gt and above which fall within the scope of SOLAS Regulation II-1/3-12.2, namely all vessels which are delivered before 1 July, 2018, that:are contracted for construction before 1 July 2014, with the keel laid on or after 1 January 2009; orIn the absence of a building contract, have their keel laid on or after 1 January, 2009, but before 1 January, 2015;and that have not previously had noise measurements taken and do not have a noise survey report on board.These ships are required to:carry out a noise survey, covering at least the requirements in paragraphs 2.8.3, 4.2.1, 4.3 and the model format in Appendix 1 of the Noise Code 1981' as adopted by IMO Resolution.

Code on Noise Levels On Board Ships enters into force on July 1st, 2014 On 1 July 2014, the International Convention for the Safety of Life at Sea (SOLAS) will be amended to make the 'Code on Noise Levels On Board Ships' (the Noise Code) mandatory for new vessels.The MSC 91, from 26 to 30 November 2012, adopted a new SOLAS regulation II-1/3-12 to require new ships to be constructed to reduce on-board noise and to protect personnel from noise, in accordance with the revisedCode on noise levels on board ships, also adopted, which sets out mandatory maximum noise level limits for machinery spaces, control rooms, workshops, accommodation and other spaces on board ships. The Code supersedes the previous non-mandatory Code, adopted in 1981 by resolution A.468(XII).The Code's purpose is to provide standards on preventing noise levels hazardous to human health and reduce seafarers' exposure to such noise levels.It gives consideration to the need for communication and the ability to hear audible alarms, the importance of protecting the seafarer from noise-induced hearing loss,and the provision of an acceptable degreeof comfort during rest hours. Introduction of the Noise Code will lead to changes in SOLAS, with Chapter II-1 Regulation 36 being ...
