DC Electric Propulsion Solution uses all the energy efficient features of a Hybrid Propulsion Machinery plus a ship-wide DC-link power distribution system. With the DC-link distributing electrical power to all consumers, energy efficiency is increased by up to 35%. The Hybrid DC Machinery concept includes variable speed Auxiliary Generators and Permanent Magnet technologies for the rotating machines. With the ship-wide DC-link power distribution fault currents are kept to a minimum thanks to the precise controls of the dedicated inverter units per consumer. The need for large switchboards and bulky transformers are therefore minimised, which means greater savings in space and weight as well as far better total efficiency.

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-link 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.
Variable frequency drive technology for generator/motor applications is a compact and robust modular design.
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.
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.
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 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 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.
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 150 vessels worldwide.
