Full title and description

St IEC 61892-1-2019 — Mobile and fixed offshore units — Electrical installations — Part 1: General requirements and conditions. This part of IEC 61892 provides general requirements and conditions for electrical installations and equipment on mobile and fixed offshore units used in the offshore petroleum industry (drilling, production, accommodation, processing, storage and offloading) and on associated installations such as pipeline/pumping stations, compressor stations and single buoy moorings. It is applicable to permanent, temporary and transportable installations and to AC and DC systems without a voltage-level limitation.

Abstract

IEC 61892-1:2019 (Edition 4) specifies environmental, electrical-supply and siting requirements, protections against external influences and electrical shock, and rules for ignition-source control for offshore electrical installations. The edition includes guidance on cold-climate protection and surface treatment/painting systems and consolidates certain protection and ignition-source requirements previously placed in other parts of the series. It cancels and replaces the 2015 edition.

Scope

This document is applicable to electrical installations and equipment in mobile and fixed offshore units and associated installations in the offshore petroleum industry. It applies to installations whether permanent, temporary or transportable, and to AC and DC installations without an internal voltage limitation (referenced product standards may impose limits). The standard excludes fixed medical equipment, the electrical installations of tankers and control of non-electrical ignition sources; specific exceptions and cross-references to other maritime and product standards are noted within the text.

Key topics and requirements

• Environmental classification and conditions for offshore electrical equipment (temperature, humidity, corrosivity considerations and cold-climate guidance).
• Power supply characteristics and system voltage/quality requirements; removal of fixed voltage limitations in this edition.
• Location, siting and mounting rules for electrical equipment on units (minimum degrees of protection, positioning relative to hazards).
• Protection against external influences (corrosion, mechanical damage, splash/exposure) and guidance on surface treatment and protective painting systems.
• Protection against electric shock and requirements for earthing/grounding arrangements (see related parts for system-design specifics).
• Ignition-source control requirements (moved into Part 1 from Part 7 in this edition) and hazardous-area considerations (cross-referenced to the series where appropriate).
• Informative guidance (examples) on selection, installation and maintenance practices for offshore electrical equipment.

Typical use and users

Primary users are electrical engineers, system designers, project engineers, equipment manufacturers, offshore operators, installation contractors, class societies and certification bodies involved in design, procurement, installation and inspection of electrical systems on mobile and fixed offshore units. The document is used to define minimum general requirements to ensure safety, compatibility and environmental robustness of offshore electrical installations.

Related standards

IEC 61892‑1 is Part 1 of the IEC 61892 series. Other parts of the series address system design (Part 2), equipment (Part 3), selection and installation for specific unit types (Parts 4–6) and hazardous-area requirements (Part 7). Users commonly consult the other IEC 61892 parts in combination with product standards (for motors, switchgear, cables, etc.), IMO MODU Code and relevant ISO standards for non-electrical equipment and hazardous-area standards where applicable.
