Shore Power

Shore power, also known as Onshore Power Supply (OPS) or Alternative Marine Power (AMP), is becoming standard in newbuilds and offers a cost-effective retrofit solution for existing vessels. By connecting to the onshore electrical grid while in port, vessels can reduce fuel consumption, emissions, and noise. Instead of running auxiliary engines, onboard loads and energy storage systems can be powered directly from the grid. WE Tech continues to develop advanced OPS solutions that support efficient and reliable port operations.

Technologies Used

  • WE Drive™
  • DC-bus power distribution
  • Electric transformer
  • Shore connection

Customer Benefits

  • Reduced fuel consumption, emissions, and noise by connecting to onshore electricity while in port
  • Instead of running auxiliary engines, ships can use clean shore power to supply onboard loads and charge energy storage systems

Solutions Leading Marine Electrification

WE equip your ship for success.

Our solutions build on widely proven technologies and are applicable for most ship types and propulsion machinery (e.g. low speed direct driven propeller with 2-stroke Main Engine, or medium speed reduction gear driven propeller with 4-stroke Main Engine). 

WE Tech solutions utilise variable frequency drive technology (WE Drive™), permanent magnet generator technology, DC-bus power distribution and Energy Management System(EMS).

With our domain expertise, you can get a ship with an energy system built the way it should.

WE Drive® 

Read more

Variable frequency drive technology for generator/motor applications is a compact and robust modular design.

Variable Speed Generator

Read more

The variable speed permanent magnet generator is lightweight, and compact-sized with the highest efficiency over the full speed and power range. It is virtually maintenance-free. We also offer solutions based on synchronous and asynchronous generator technology.

Energy Storage Solutions

Read more

We use the latest lithium-ion technology from the Energy Storage System (ESS) suppliers. With a DC-DC converter, we integrate the ESS into our solution.

Energy Management System

Read more

With the Energy Management System(EMS), we control various operation modes of the ship as well as start/stop sequences, etc. The EMS also interfaces with other control systems on board a ship.

Shore Power Solution

Read more

Shore power is conditioned for the vessels’ electrical system via the WE Drive™. Vessels become unaffected by the variations in voltages and frequencies of the national power grids worldwide – shore power is always matching.

Fuel Cell Solution

Read more

Fuel Cell Integration via DC/DC conversion to the ship energy efficient power distribution system. Seamless operations utilising Fuel Cells and ESS combinations for zero emission power.

Reference cases

Solutions applied on over 300 vessels worldwide

We have been focusing on lowering emissions for years by providing cost-effective and sustainable lifetime solutions to the shipping industry. Our benchmarking solutions have already been applied to more than 300 vessels worldwide.
