The E-Flex concept is described as a new generation of Ropax vessels focusing on energy efficiency and flexibility. This goal can be easily achieved via introducing the energy efficient solutions innovated by WE Tech Solutions. 

The compact and robust modular designed WE Drive (Variable Frequency Drive) enables efficient, flexible and economical power distribution. In Power Take Out (PTO) mode, the propulsion machinery operates in combinator/variable speed mode via WE Drive, while the shaft generator provides the vessel’s electric network with considerable electrical power that results in variable speed and optimized efficiency of the main engine. 

The Efficient Power Distribution solution utilizes the common DC-link to distribute power in energy efficient and economical ways. Large electrical consumers such as thruster or large compressors can have their dedicated Inverter Units (INU) connected directly to the common DC-LINK. The solution also enables efficient power distribution and controlled short circuit currents, which allows lighter switchboards in marine installations.
