What is BS IEC 61892-2 - System design of electrical installations about?
BS IEC 61892-2 is the second part of the IEC 61892 series that discusses mobile and fixed offshore units.
BS IEC 61892-2 is applicable to 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.
BS IEC 61892-2 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.
Note: BS IEC 61892-2:2019 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
Who is BS IEC 61892-2 - System design of electrical installations for?
BS IEC 61892-2 on system designs for electrical installations for mobile and fixed offshore units are useful for:
- Offshore unit owners
- Offshore unit designers
- Offshore unit installers
Why should you use BS IEC 61892-2 - System design of electrical installations?
BS IEC 61892-2 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
- 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
BS IEC 61892-2 gives information and guidance on topics such as:
- Applicable examples of HVDC VSC technology
- Guidelines for illumination level
These guidelines of BS IEC 61892-2 help you set up a system of electrical installations for offshore units that function as intended and maximize the safety of operations within the offshore units.
What’s changed since the last update?
BS IEC 61892-2:2019 supersedes BS IEC 61892‑2:2012, which is withdrawn. BS IEC 61892-2:2019 includes the following significant technical changes concerning BS IEC 61892‑2:2012:
- 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
- The requirement in relation to dead start has been added
- The requirement for emergency stop for motor-driven fuel-oil transfer and fuel-oil pressure pumps has been added.
