scope:

This part of IEC 61892 specifies additional characteristics for electrical installations in mobile units. It applies to installations that depend on buoyancy, such as column-stabilized units (semi submersible units), ship- or barge-type units as well as jack-up units. It specifies the additional characteristics for such units, used during transfer from one location to another and for drilling, production, accommodation, processing, storage and offloading purposes. It applies to all installations, whether permanent, temporary, transportable or hand-held, to AC installations and DC installations without any limitation on voltage level. Referenced equipment standards may give voltage level limitations. This document specifies requirements such as those of: - environmental conditions; - limits of inclination for the unit where the equipment is required to operate; - bilge pumps; - navigation and obstruction lights; - steering gear; - ballast system; - jacking systems; - anchoring systems. For electric propulsion reference is made to IEC 60092-501 For Dynamic Positioning systems reference is made to relevant IMO requirements
