WE Tech Hybrid Propulsion for Wasaline

The  provider of energy-efficient solutions for shipbuilding, WE Tech Solutions has been awarded the contract for delivery of an avant-garde Hybrid Electric Propulsion solution to Rauma Marine Construction (RMC).

The solution includes Propulsion drives, Energy Storage System (battery banks and DCDC converters), Main Propulsion Switchboards, Shore connection switchgears, Energy Management System and the Propulsion Control System.

WE Tech and RMC will together bring Wasaline’s new RoPax ferry to the next level of sustainable shipping. The new ferry is being built by RMC in Rauma Finland and is scheduled for delivery in May 2021.

The Ice Class 1A Super ferry, with a freight capacity of 1,500 lane-metres for trucks on two cargo decks and capacity for 800 passengers, will be operating daily in the Gulf of Bothnia between the city of Vaasa in Finland and city of Umeå in Sweden.

The Hybrid Electric Propulsion ferry will be equipped with four generators that supply energy for propulsion and electrical power demand in normal sailing mode.

A Zero Emission Sailing Mode utilises battery banks only for vessel’s propulsion and electrical power demand and is initiated in harbour manoeuvring mode. While stationary in the harbour, the vessel’s electrical system and re-charging of the energy storage system will be supplied by the high-power shore connection.
