FinFerries chooses Schottel EcoPellers for hybrid-electric ferry
The latest addition to FinFerries’ fleet, the recently launched ferry Altera, features high-efficiency azimuth thrusters from Schottel

FinFerries has chosen to install its battery-powered vessel Altera with high-efficiency azimuth thrusters from Schottel.

The electrically powered hybrid ferry, which is scheduled to enter operation in 2023, is currently under construction at the Polish shipyard Crist. Altera will be able to sail solely on 2×0.6 MWh batteries, charging the batteries with renewable electricity on shore while loading and unloading. Diesel generator sets will serve as a backup source of power.

The propulsion system of the ferry consists of two electrically driven Schottel EcoPellers type SRE 430 (950 kW each). The SRE features a propeller diameter of 2.35 m. The azimuth thrusters are ice-strengthened according to Finnish-Swedish Ice Class 1B. Thanks to this, the ferry can be deployed in the icy waters of Southwest Finland at any time of the year.

The hydrodynamically optimised design of the EcoPeller enables it to generate maximum steering force to achieve maximum efficiency and course stability. This reduces fuel consumption and ensures both lower operating costs and emissions.

Mats Rosin, CEO of 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.”
