Marine Electrical Services

From cabling and switchboards to generators, drives, automation and shore power — our engineers install, upgrade and repair the systems that keep your vessel working. In the yard, in port, on board or offshore.

What we do

One electrical plant. Engineers who understand all of it.

Your vessel's electrical plant is one system. Generators feed the main switchboard, the switchboard feeds distribution, and distribution feeds every motor, drive and controller on board — change one part and the rest feel it. That's why we work across the whole plant: new installations, upgrades and fault finding.

Your deadline sets the plan — a docking, a port call, a regulation date. We survey first, plan against that date and finish with testing and commissioning, so you sign off on work that is already proven.

Project proof

OOCL Montreal at Sefine Shipyard

On the 4,402 TEU container ship OOCL Montreal, Orion Marine delivered the AMP shore power and marine-electrical scope during a combined yard period at Sefine Shipyard in 2026 — working to the yard's dock schedule, so the vessel left commissioned.

How a job runs

From survey to handover

Installation, retrofit or repair — every job follows the same disciplined sequence.

  1. 01

    Survey

    Survey and scope

    We look at the installation, the drawings and the operating conditions, and agree a scope that fits the vessel's schedule.

  2. 02

    Engineer

    Engineering and mobilisation

    Design, drawings and equipment are prepared against the deadline, and the team is mobilised to the yard, the port or the vessel.

  3. 03

    Deliver

    Work, testing and handover

    The work is carried out, tested and commissioned, and handed over with the test records.

FAQ

Questions about marine electrical work

What does a marine electrical contractor do?
Installs, upgrades and repairs a vessel's electrical systems — cabling, switchboards and distribution, generators, motors and drives, automation and control — and proves the work through testing and commissioning. Orion Marine covers that scope, with shore power as a specialization.
Can you work on a vessel outside Türkiye?
Yes. Our base is in Istanbul, and the team mobilises internationally when a project requires it — to a shipyard, a port or the vessel itself. Tell us where the vessel will be, and when.
Do you work on vessels in service as well as new installations?
Yes. We install new electrical systems and equipment, and we upgrade, retrofit and repair vessels that are already trading. See installation and outfitting and retrofit and modernization.
What do you need from us to scope a job?
The vessel's name and type, where she will be and when, what the work is, and any drawings or reports you already have. A survey on board usually follows before the scope is fixed.
