Actemium has been a pioneer in port electrification for over 15 years.

With more than 30 OPS projects delivered worldwide (France, Sweden, Netherlands, Spain, UAE…), we bring end-to-end expertise and tailor-made solutions to support the global maritime energy transition.

Fossil Fuels Off, Electrical Power On

When ships are docked, their auxiliary diesel engines continue to run—emitting CO₂, nitrogen oxides, noise and vibrations that affect nearby communities and ecosystems. Onshore Power Supply (OPS) enables vessels to connect to the local grid and switch off onboard engines, improving air quality and reducing environmental and noise pollution.

OPS is endorsed by the World Port Climate Initiative and required under upcoming EU regulations such as AFIR and FuelEU Maritime (effective from 2030).

Decarbonising Ports with Reliable, Scalable and Smart OPS Solutions

Our teams handle full project scope: we advise, design, build and maintain.

Actemium provides turnkey OPS systems, combining:

  • High-voltage conversion and smart cable connection
  • Multi-disciplinary teams: electrical, mechanical, automation
  • Modular and scalable architectures
  • Broad expertise like cruise, ferry, and container terminals

We offer reliable industrial solutions with long-term operability to support port decarbonisation objectives. Our offer covers both sides of the shore power equation:

  • Onshore: grid connection, substations, power conversion, CMS
  • Onboard: ship interface engineering, coordination with ship owners

 

Meeting Global Market Challenges

Ports face significant hurdles when implementing OPS:

 

  • Grid Integration

A Full In-House OPS Expertise

Actemium is the only provider to fully manage the entire Onshore Power Supply system — from design to commissioning. We develop and manufacture our own customized Cable Management System (CMS) to ensure optimal performance and integration.

As a manufacturer-independent integrator, Actemium adapts each system to your operational and spatial constraints, with fixed or mobile setup. Three CMS options are available:

  1. Cruise CMS: heavy-duty, mobile unit with articulated crane for large vessels
  2. Ferry CMS: compact, agile, designed for frequent docking
  3. Container CMS: linear chain-on-track system along the quayEach CMS is custom-engineered to ensure ergonomic operation, fast connection and minimal visual impact.
