For design of plants and equipment for manned underwater operations on vessels, see Section 1. Guidance Notes are not binding. The drilling fluid system area should be designed to avoid harmful exposure for personnel and the environment. New operators shall, oss, evaluate whether it is prudent to operate with the exemptions granted, and whether changed conditions exist that make it necessary to apply for a new exemption, see Section 70 of the Framework Regulations.
Radiation as mentioned in the first subsection, means ionising and non-ionising radiation. There should also be specific lighting if the general lighting is not adequate for readings, service and maintenance. In order to fulfil the requirement relating to helicopter decks as mentioned in the first subsection, the NORSOK C standard, with exception of Chapter 14 on the minimum size of helicopter decks, may be used as an addition to the requirements in the regulations of the Civil Aviation Authority.
Re Section 65 Facilities and equipment for manned underwater operations To fulfil the requirement for compensator and disconnection systems as mentioned in the first and second subsections, the NORSOK D standard Chapters 5 and 6 should be used, with the following additions: Re Section 71 Marking of facilities Re Section 73 Lifts In order to fulfil the requirement regarding materials and material protection as mentioned in literas a, b and c, the following standards should be used in the area of health, working environment and safety: For general requirements related to design, see Sections 5 and It is important to identify differences between these at an early stage and assess these.
Particular consideration ox be given to the installation’s potential earth fault currents and leakage currents.
