From initial system definition to final technical records

Offshore electrical installations rely on coordinated engineering information and correctly selected equipment. Drawings, cable data, load calculations, protection devices and area-classified hardware all need to work together as part of the same electrical system.

01
Electrical Engineering

Design deliverables for offshore electrical installations

Core drawings and calculations used to define electrical architecture, cable routing, connected loads and installation interfaces.

Hazardous Area Systems

Electrical distribution for Zone 1 & Zone 2

Area-classified offshore installations require electrical equipment selected for the applicable hazardous zone, environment and project specification.

Industrial offshore processing environment
Zone 1

Zone 1 Distribution Boxes

Electrical distribution equipment intended for Zone 1 hazardous locations, subject to applicable equipment protection and certification requirements.

Zone 2

Zone 2 Distribution Boxes

Distribution equipment selected for Zone 2 environments with suitable enclosure, protection and certification characteristics.

Interfaces

Cable Entry & Termination

Glands, junction boxes and termination accessories compatible with cable construction and the hazardous-area classification.

Technical Documentation

From system drawings to as-built records

The document set becomes the technical record of the offshore electrical system and supports installation, inspection and future maintenance.

01

System Definition

Block diagrams and single-line diagrams.

02

Detailed Design

Wiring, terminations and cable schedules.

03

Design Calculations

Load, breaker and lux calculations.

04

Final Records

Compiled documentation and as-built drawings.

Technical note

Individual design, supply, certification or execution capabilities should be confirmed for the relevant ZURIC entity before publication as contractual commitments.
