The latest addition to FinFerries’ fleet, the hybrid electrically-powered 'Altera', scheduled to begin operation in 2023, will feature high-efficiency azimuth thrusters from Schottel.

The vessel is currently under construction at the Polish shipyard Crist. Altera will be able to sail solely on battery power, charging its batteries with renewable electricity.

Mats Rosin, CEO Suomen Lauttaliikenne Group said: “Altera means proud, excellent, which is well suited as we are proud of this technology and are thrilled to welcome another eco-friendly electrically powered ferry to Finland. By supplying efficient and sustainable EcoPellers, Schottel makes a significant contribution on our path towards a greener future.”

The propulsion system of the LMG design ferry consists of two electrically driven 950kW Schottel SRE 430 EcoPellers with propeller diameter of 2.35m. The azimuth thrusters are ice-strengthened according to Finnish-Swedish Ice Class 1B, allowing the ferry to be deployed in the icy waters of Southwest Finland at any time of the year.

Equipped with two batteries, each of 600kWh, Altera will service its route using only its own batteries which are charged directly from shore while loading and unloading. Diesel generator sets will serve as a backup source of power.

Thanks to the combination of propeller thrust and a course-stabilising fin, the hydrodynamically optimised design allows the EcoPeller to generate maximum steering forces and high overall efficiency and course stability. This reduces fuel consumption and ensures both lower operating costs and emissions.

Altera measures 100m in length and 17m in width, with space for up to 90 cars and a maximum of 375 passengers.

FinFerries and Schottel are linked by a long-standing partnership in the modernisation and new building business. In total, more than five ferries have already been equipped with Schottel propulsion systems, leading to greater standardisation within the fleet.

Suomen Lauttaliikenne Group, which operates under the name FinFerries, is a state-owned operator of both commuter ferries and road ferries, servicing 42 routes across Finland.
