Full title and description

IEC 61892-6:2019 — Mobile and fixed offshore units — Electrical installations — Part 6: Installation. This international standard gives specific requirements and guidance for the installation of electrical equipment on mobile and fixed offshore units used in the petroleum and offshore industries, covering permanent, temporary and transportable installations for AC and DC systems (no intrinsic voltage limit).

Abstract

IEC 61892-6:2019 (4th edition) specifies installation requirements for electrical equipment on mobile and fixed offshore units — including drilling, production, accommodation, processing, storage and offloading units, pipeline/pumping stations, compressor stations and single-buoy moorings. Topics include protection during storage and installation, location and installation of generators, motors, transformers, switchgear, converters and batteries, cable and wiring practices, earthing and bonding, lightning protection, testing and documentation. The edition updates and replaces the previous 2013 edition.

Scope

The standard applies to the installation of electrical equipment in mobile and fixed offshore units used in the offshore petroleum industry, whether installations are permanent, temporary, transportable or hand-held and for both AC and DC systems. It establishes installation requirements and precautions for equipment storage and handling, placement and securing of generators, motors and transformers, assembly and installation of switchgear and controlgear, semiconductor converters, UPS, batteries, luminaires, heating appliances, trace and surface heating, cable routing and supports, earthing/ bonding arrangements and lightning protection; it also covers testing of completed installations and required documentation. The document does not apply to fixed medical equipment, electrical installations of tankers or to the control of ignition sources beyond those created by electrical equipment.

Key topics and requirements

• Protection of equipment during storage and the installation period (mechanical, environmental, welding/painting damage prevention).
• Installation practices for generators and large motors with regard to motion, noise, vibration and accessibility.
• Transformer siting and installation requirements (safety, ventilation, protection).
• Requirements for installation of switchgear, controlgear assemblies, semiconductor converters and UPS systems.
• Installation, charging and ventilation requirements for secondary cells and batteries.
• Guidance on luminaires, heating/cooking appliances, trace and surface heating installations.
• Cable management: selection, routing, supports, segregation of power/control/communication circuits and high-voltage considerations.
• Earthing arrangements and protective bonding tailored to offshore structures and floating units.
• Lightning protection principles applicable to offshore units.
• Testing, inspection and documentation requirements for completed electrical installations.

Typical use and users

Used by offshore electrical designers and engineers, installation contractors, naval architects, platform and floating unit operators, classification societies, safety and compliance personnel, procurement teams specifying electrical installation requirements, and regulators or consultants responsible for offshore electrical safety and certification.
