Electrical Engineering

System level electrical design—schematics, load calculations, COTS component selection, and detailed BOMs—integrated across mechanical, control, and hydraulic disciplines and documented for rapid stakeholder review.

Power, protection, and integration—done right

Our electrical engineers design complete equipment power and distribution architectures that align with your operational needs and regulatory expectations. We produce system level schematics, load calculations, and specify commercial offtheshelf (COTS) electrical components that shorten lead time and simplify maintenance.

What we deliver

Deliverables include detailed BOMs and the supporting technical documentation you need for HAZID/HAZOPS/FMECA workflows. All designs are coordinated with mechanical, control, and hydraulic teams to deliver integrated, buildable solutions.

System schematics & singleline diagrams

Power distribution, protection, earthing/bonding, and cable schedules.

Electrical load calculations

Source sizing, feeders, voltage drop, diversity factors, starting currents, and fault levels.

COTS component selection

Breakers, contactors, drives, power supplies, junction boxes, enclosures, and connectors—specified to duty and environment.

Detailed BOMs

Part numbers, materials, ratings, and vendor references tied to drawings and revision control.

Code & standard alignment

Mapping designs to applicable standards and site procedures (e.g., IEC/BS, Machinery/UKCA)

Interface control

I/O lists, wiring tables, connector pinouts, and interlock matrices that align with control/hydraulic systems.

Focussed on delivery

Subco delivers high-quality engineering work, on demand. We help companies deliver critical packages of work—without the delays, overhead, or commitment of hiring. Whether it’s a capacity or capability gap, we provide defined, fixed-price solutions that keep projects moving.
