Navy Vessels

What we offer for Navy Vessels

Solution Five Hybrid Electric Propulsion system: ship-wide DC-bus power distribution with variable speed shaft and auxiliary generators, is commonly used for Navy vessels. With a Generator connected via Inverter Unit to DC-link power distribution the speed/frequency of the generator is independent of any synchronous speed restrictions.

  • Compliance with environment regulations IMO’s EEDI and EEXI.

WE Tech's Solution for Navy Vessels

Solution Five Hybrid Electric Propulsion

DC Power from the frequency drives for the shaft generator can be distributed to inverter units for powering heavy consumers, such as a bow thruster and a cargo handling system. The use of frequency inverter units over normal AC frequency converters will greatly reduce THD on main switchboard.

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.

Peak-shaving

The Peak-shaving mode can be used for supporting auxiliary engines by taking on fast load changes and keeping electrical load as seen for auxiliary engines constant.

Spinning reserve

Spinning reserve functionality provides an energy reserve for power generation, allowing for single generator operation.

Black-out prevention

In case a generator is unexpectedly shut down, the ESS keeps the electrical network energized until a Stand-by Auxiliary Generator comes on-line.

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.
