Anotation

IEC 61892-5:2019 specifies additional characteristics for electrical installations in mobile units. It applies to installations that depend on buoyancy, such as column-stabilized units (semi­submersible units), ship- or barge-type units as well as self-elevating units. It specifies 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 concerning – 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, and – anchoring systems. For electric propulsion, reference is made to IEC 60092-501. For dynamic positioning systems, reference is made to relevant IMO requirements. 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 fourth edition cancels and replaces the third edition published in 2014. This edition constitutes a technical revision. This edition includes the following significant technical change with respect to the previous edition: a) the technical requirements as to electric propulsion have been replaced with a reference to IEC 60092-501:2013; b) the requirement for handrails on main and emergency switchboards has been added; c) requirements as to control systems and indicators for watertight doors and hatch covers have been made more specific; d) requirements concerning the holding capacity for jacking systems have been rewritten; e) requirements as to thruster-assisted mooring system have been rewritten; f) the annex regarding enhanced system verification (HIL test) for dynamic positioned mobile units has been relocated to IEC 61892-2:2019. LIEC 61892-5:2019 specifie des caracteristiques supplementaires pour les installations electriques dans les unites mobiles. Elle sapplique aux installations pour lesquelles la flottabilite est essentielle, comme les unites stabilisees de type colonnes (unites semi-submersibles), les unites de type navire ou barge, ainsi que les unites autoelevatrices. Elle specifie les caracteristiques supplementaires pour ce type dunites, utilisees lors du transfert dun lieu a un autre et pour le forage, la production, les lieux dhabitation, le traitement, le stockage et le dechargement. Elle sapplique a toutes les installations, quelles soient permanentes ou provisoires, transportables ou portatives, aux installations en courant alternatif et aux installations en courant continu sans limitation du niveau de tension. Les normes des equipements references peuvent fournir des limites de niveau de tension. Le present document specifie des exigences pour – les conditions denvironnement, – les limites dinclinaison de lunite sur laquelle lequipement doit fonctionner, – les pompes de cale, – les feux de navigation et dobstacle, – lappareil a gouverner, – le systeme de ballast, – les systemes de levage, et – les systemes dancrage. Pour la propulsion electrique, il est fait reference a lIEC 60092-501. Pour le systeme de positionnement dynamique, il est fait reference aux exigences correspondantes de lOMI. Le present document ne sapplique pas – aux equipements fixes destines aux applications medicales, – aux installations electriques des navires-citernes, et – au controle des sources dincendie autres que celles generees par lequipement electrique. Cette quatrieme edition annule et remplace la troisieme edition parue en 2014. Cette edition constitue une revision technique. Cette edition inclut les modifications techniques majeures suivantes par rapport a ledition precedente: a) les exigences techniques relatives a la propulsion electrique ont ete remplacees par une reference a lIEC 60092-501:2013; b) les exigences relatives aux tableaux principaux et aux tableaux durgence ont ete ajoutees; c) les exigences relatives aux systemes de controle et aux indicateurs des portes etanches et des couvercles decoutille ont ete precisees; d) les exigences relatives a la capacite de maintien des systemes de connexion ont ete reecrites; e) les exigences relatives au systeme de mouillage assiste par propulseur ont ete reecrites; f) lannexe relative a lessai de verification de systeme ameliore (essai de materiel incorpore) pour unites mobiles a positionnement dynamique a ete placee dans lIEC 61892-2:2019.
