DS/IEC 61892-4:2007

Mobile and fixed offshore units - Electrical installations - Part 4: Cables

This part of IEC 61892 specifies requirements for the choice and installation of electrical*cables intended for fixed electrical systems in mobile and fixed offshore units, including*pumping or pigging” stations, compressor stations and exposed location single buoy*moorings, used in the offshore petroleum industry for drilling, production, processing and for*storage purposes.*The reference to fixed electrical systems includes those that are subjected to vibration due to*the movement of the unit, e.g. cables installed on a drag chain, and not those that are*intended for repeated flexing. Cables suitable for repeated flexing use are detailed in other*IEC specifications, e.g. IEC 60227 and IEC 60245, and their uses on board offshore units are*restricted to those situations which do not directly involve exposure to a marine environment,*e.g. portable tools, domestic appliances, etc.*The following types and applications of cables are not included:*• optical fibre cables;*• sub-sea and umbilical cables;*• cables supplying downhole pumps;*• data, telecommunication and radio frequency cables.
