It applies to all installations, whether permanent, temporary, transportable or hand-held, to AC installations and DC installations, without any voltage level limitation. Referenced equipment standards may give voltage level limitations. This document specifies requirements such as those concerning – sources of electrical power for manned and unmanned units, – system earthing, both for low-voltage and high-voltage installations, – interface for electric transmission systems with power supplied from shore, between interconnected offshore units, and with power supplied by offshore units to subsea installations, – distribution systems, – cables and wiring systems, – system studies and calculations, – protection against electrical faults, – lighting, – energy control, monitoring and alarm systems, and – turret/swivel. This document gives information and guidance on topics such as – applicable examples of HVDC VSC technology, and – guidelines for illumination level. This document does not apply to – fixed equipment for medical purposes, – electrical installations of tankers, and – control of ignition sources other than those created by electrical equipment. This third edition cancels and replaces the second edition published in 2012. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition: a) the requirement for sources of electrical power has been rewritten. Requirements both for manned and unmanned units are given. Requirements for essential services of electrical power have been added; b) the requirement in relation to dead start has been added; c) the requirement for emergency stop for motor-driven fuel-oil transfer and fuel-oil pressure pumps has been added; d) general requirements regarding cables and wiring systems have been added; e) the description of unit interfaces to electrical transmission systems has been included; f) requirements in relation to energy control, monitoring and alarm system have been rewritten; g) new clauses regarding swivel/turret and unmanned facilities have been added; h) informative annexes regarding the following have been added: – essential source of electrical power; – emergency source of electrical power; – applicable examples of HVDC VSC technologies; – swivel/turret; – power sources for unmanned units, with separate or combined main and emergency switchboard; – alternative power sources of electrical power – general requirements; – illumination level; – enhanced software simulation; – architecture for energy control, monitoring and alarm system.
