§ 24 Vibrations

Facilities shall be designed so that vibrations do not harm personnel on the facility, or complicate the personnel's important duties.
Section last changed: 01 January 2013

Regulations laid down by the Ministry of Labour and Social Inclusion 6 December 2011, pursuant to the Working Environment Act, and entering into force 1 January 2013, contain further provisions on protection against mechanical vibrations. Clarification of the scope is directly evident from the individual regulations. In addition, reference is made to the lawmirror (in Norwegian only) of the Norwegian Labour Inspection Authority, in which the requirement of the regulations that are being repealed upon entering into force of the new regulations in pursuance of the Working Environment Act, are included.
In order to fulfil the requirements relating to vibrations, the NORSOK S-002 standard Chapter 6.1, 7,1 7.2, 8.2 and A.5 in Annex A should be used. For mobile facilities, this standard should be used for vibrations in the 5–80 Hz frequency range.
In order to assess the reaction of human beings to low-frequency vibrations, the NS 4931 standard should be used. The Norwegian Shipowners' Association Norm for physical-chemical working environment on mobile facilities built before 1 August 1995 and operating on the Norwegian shelf (in Norwegian only) can be used as an alternative to NORSOK S-002 for the areas covered by the norm.
