WE Tech's Solution for Container Vessels

WE Tech Solution One is a shaft generator solution based on variable frequency drive and permanent magnet generator technology.

With Solution One the electrical power generation efficiency for the vessel reaches the highest possible level. The main engine produces both propulsion and electrical power for the vessel. This limits the running hours of auxiliary engines and thus reduces both fuel consumption and emissions.

Thanks to WE Tech’s modular integration platform, Solution One can be extended with various options to further improve the energy efficiency of the vessel.

Why WE Tech Solutions

WE Tech Solutions is a company specialised in developing energy solutions for ships and the market leader for permanent magnet shaft generator solutions. The company has long experience in developing the most energy efficiency solution for any ship type.

Key Benefits

  • Reduced fuel consumption and emissions due to the difference in SFOC between the main engine and auxiliary engines
  • Increased flexibility on auxiliary engine selection
  • Reduced installed power in the vessel
  • A permanent magnet shaft generator is virtually maintenance-free, offering the highest efficiency and highest power density.

WE Tech's Solution for Container Vessels

Solution One Power Take Out

Taking advantage of the already existing variable frequency drives the vessel can allow shore frequencies of both 50Hz and 60Hz to be connected to the vessel. This will further enhance the environmental footprint when auxiliary engines can remain shut off during cargo operations in port.

As an option the shaft generator can have two separate windings, each winding feeding the main switchboard via its own frequency drives. This will eliminate a blackout in case of a failure in any of the two feeders as the other remain intact.

Solutions towards Zero Emission Shipping

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-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.
