Retrofit for 2 stroke application

Retrofit solution eliminates the need for traditional auxiliary engines during sea operations, reducing energy waste and improving overall vessel efficiency. Installing an in-line shaft generator directly on the propeller shaft line enables vessels to harness the main engine’s mechanical power to generate electricity. By generating electricity with the main propulsion engine instead of auxiliary generators, the retrofit system reduces total fuel consumption significantly.

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®

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

Variable Speed Generator

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

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

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

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

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.
