IEC 61892-2:2019 is applicable to system design of electrical installations and equipment in mobile and fixed offshore units including pipeline, pumping or "pigging" stations, compressor stations and single buoy moorings, used in the offshore petroleum industry for drilling, production, accommodation, processing, storage and offloading purposes.
\nIt 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.
\nThis document specifies requirements such as those concerning
\n\u2013 sources of electrical power for manned and unmanned units,
\n\u2013 system earthing, both for low-voltage and high-voltage installations,
\n\u2013 interface for electric transmission systems with power supplied from shore, between interconnected offshore units, and with power supplied by offshore units to subsea installations,
\n\u2013 distribution systems,
\n\u2013 cables and wiring systems,
\n\u2013 system studies and calculations,
\n\u2013 protection against electrical faults,
\n\u2013 lighting,
\n\u2013 energy control, monitoring and alarm systems, and
\n\u2013 turret\/swivel.
\nThis document gives information and guidance on topics such as
\n\u2013 applicable examples of HVDC VSC technology, and
\n\u2013 guidelines for illumination level.
\nThis document does not apply to
\n\u2013 fixed equipment for medical purposes,
\n\u2013 electrical installations of tankers, and
\n\u2013 control of ignition sources other than those created by electrical equipment.
\nThis third edition cancels and replaces the second edition published in 2012. This edition constitutes a technical revision.
\nThis edition includes the following significant technical changes with respect to the previous edition:
\na) 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;
\nb) the requirement in relation to dead start has been added;
\nc) the requirement for emergency stop for motor-driven fuel-oil transfer and fuel-oil pressure pumps has been added;
\nd) general requirements regarding cables and wiring systems have been added;
\ne) the description of unit interfaces to electrical transmission systems has been included;
\nf) requirements in relation to energy control, monitoring and alarm system have been rewritten;
\ng) new clauses regarding swivel\/turret and unmanned facilities have been added;
\nh) informative annexes regarding the following have been added:
\n\u2013 essential source of electrical power;
\n\u2013 emergency source of electrical power;
\n\u2013 applicable examples of HVDC VSC technologies;
\n\u2013 swivel\/turret;
\n\u2013 power sources for unmanned units, with separate or combined main and emergency switchboard;
\n\u2013 alternative power sources of electrical power \u2013 general requirements;
\n\u2013 illumination level;
\n\u2013 enhanced software simulation;
\n\u2013 architecture for energy control, monitoring and alarm system.<\/p>\n","protected":false},"excerpt":{"rendered":"
