Benefits
WE EQUIP YOUR SHIP FOR SUCCESS
- Less installed power thanks to increased efficiency and flexibility of the electrical system.
- Reduced weight of the electrical system.
- Smaller Main Switch Board footprint and less copper in cabling and bus-bars due to limited fault currents in the DC-link power distribution.
- Lower THD (Total Harmonic Distortion) in the electrical system thanks to Low Harmonic AFE (Active Front End) drive technology.
- Reduced electric power generation costs as the Shaft Generator is driven by the Main Engine in variable (optimal) speed.
- Reduced fuel and maintenance costs with stopped Auxiliary Generators.
- Reduced losses in electrical power distribution.
- Propulsion machinery and/or electrical power generating machinery are always operating at optimal duty point.
- Take Me Home/Take Me Away operating modes.
- Safe return to port with Auxiliary Propulsion Drive.
- Boost modes: Low-load optimisation/Ice-boost mode.
- Black-out prevention with battery packages connected to DC-link power distribution.
- Dual or quad split of electrical power distribution.
- Lowered fuel consumption.
- Reduced emissions (CO2 + NOx + SOx + PM) thanks to improved efficiency of propulsion machinery, electrical power generation and distribution.
- Our smart solutions remove traditional design limitations and ensure that propulsion machinery, cargo handling and electrical power distribution are always operating with maximum efficiency.
- Power-dense permanent magnet technology cuts down machinery size and weight.
- The WE DriveTM generates at least 50 % cheaper shore power compared to electricity generated on-board the vessel.
- Vessels are not dependent on various voltages and frequencies of national power grids worldwide.
- Cost savings and reduced environmental footprint due to stopped Auxiliary Generators at the port.
- Battery packages connected to DC-link power distribution systems.
- Energy reserve for electrical load peak shaving and black-out prevention.
- Stable electrical load. When connected to variable speed Auxiliary Generators, battery packs prevent generator load surging during electrical load steps. This way you can generate sets to stay within your optimal operation window.
- Substantial fuel savings in DP (Dynamic Positioning) operations.
Our Technologies
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™), variable speed generator technology, energy storage system, and our Dedicated Power Management System.
With our help, 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. The WE Drive™ is either air or liquid cooled. Power range is from 0.5 MW to 6 MW in low voltage applications.
Variable Speed Generator
The variable speed permanent magnet generator is lightweight, 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 Solution
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.
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.
Dedicated Power Management System (DPMS)
With the dedicated power management system, we control various operation modes of the ship as well as start/stop sequences, etc. The DPMS also interfaces with other control systems on board a ship.
