BS IEC 61892-1:2019

What is BS IEC 61892-1 - Electrical installations about?

BS IEC 61892-1 is the first part of the IEC 61892 series that discusses mobile and fixed offshore units.

BS IEC 61892-1 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 61892-1 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 61892-1 does not apply to:

• Fixed equipment for medical purposes
• Electrical installations of tankers
• Control of ignition sources other than those created by electrical equipment

Who is BS IEC 61892-1 - Electrical installations for?

BS IEC 61892-1 on requirements and conditions for electrical installations for mobile and fixed offshore units is useful for:

• Offshore unit owners
• Offshore unit designers
• Offshore unit installers

Why should you use BS IEC 61892-1 - Electrical installations?

BS IEC 61892-1 specifies requirements such as those concerning:

• Environmental conditions
• Power supply characteristics
• Location of electrical equipment in units
• Protection against external influences
• Protection against electrical shock
• Ignition source control

BS IEC 61892-1 standardises these general requirements and conditions for electronic installations in mobile and fixed offshore units.

Overall, these general requirements provided by BS IEC 61892-1 enable you to produce electronic installations that can withstand field conditions of offshore units.

What’s changed since the last update?

BS IEC 61892-1:2019 supersedes BS IEC 61892-1:2015, which is withdrawn. This edition includes the following significant technical changes with respect to the previous edition:

• Voltage limitations have been removed
• Definitions for fixed offshore units and mobile offshore units have been included
• Tables for ambient air temperature and relative humidity have been removed, as this information will normally be given in owner's/operator's documentation for specific projects.
