Power and signal, installed and verified.
Electrical & Instrumentation, delivered with method.
Electrical and instrumentation installation and support: cable routing and termination, panel and junction box work, instrument installation, calibration support and loop checking.
Electrical and instrumentation work sits at the interface between the physical plant and the control system. Cable schedules, termination drawings and loop diagrams have to be followed precisely — and the installed result has to be verified.
WOL provides E&I crews who work from the drawings, keep records as they go, and hand over a system that is ready for commissioning.

How the work is controlled.
Three principles that shape every scope — so the client can see what will happen, when, and how it will be checked.
Drawing-driven
Cable schedules, termination drawings and loop diagrams are the reference for all work and are red-lined as work progresses.
Segregation & routing
Power and signal cables are routed and segregated per the specification to protect signal integrity.
Verification
Continuity, insulation and loop checks are recorded before energisation or commissioning.
Controls that travel with the crew.
Safety and quality arrangements apply to every scope. Specific certifications and third-party approvals are stated only where confirmed by WOL.
Permit-led execution
Every intervention starts inside the client's permit system.
Electrical isolation and lock-out confirmed before work
Hazardous-area requirements observed where applicable
Test equipment calibration maintained and recorded
Loop-check and termination records provided at handover
From scope to handover.
The same sequence on every engagement, so clients always know which stage the work is at.
Review
Drawings, schedules and area classification reviewed.
Route
Tray, conduit and cable routes installed.
Install
Cables pulled, glanded and instruments mounted.
Terminate
Terminations completed against schedules.
Check
Continuity, insulation and loop checks.
Hand over
Red-lined drawings and records issued.
Common questions about e&i.
Straight answers on how this service is scoped, mobilised and handed over.
Do you work in hazardous (Ex) areas?
Work in classified areas follows the client's specification and applicable requirements. Specific competencies are confirmed at enquiry stage. [To be confirmed]
Can you support commissioning?
Yes — loop checking and pre-commissioning support can be included so that systems are ready for the commissioning team.
Do you supply instruments and cable?
Materials are typically free-issued by the client or procured against approval as part of the scope.
