FinFerries boosts standardisation with propeller refit

Two FinFerries’ vessels have had propellors retrofitted

Both double-ended ferries, capable of holding either 14 cars or up to 60 tonnes of payload, were originally equipped with various propeller systems manufactured in different years. For the retrofit, the state-owned operator requested a tailor-made concept to allow the same propeller assembly to be used. At the same time, the solution had to be quick and easy to install.

In each ferry, two Schottel Rudderpropellers SRP150’s have been installed. Schottel said in a statement that in the Hanhivirta ferry, it was possible to install the Rudderpropeller in the existing well, but or the Mossala sister vessel, an adapter ring had to be incorporated as its well was considerably larger. To prepare for the installation at the FinFerries site, a team of engineers from the company attended a one-week training session at the Schottel Academy in Spay, Germany.

Schottel said “The advantage of this retrofit is a higher degree of standardisation in its fleet – which reduces costs for spare parts and increases availability. In addition to the two SRP150’s, FinFerries also ordered a separate unit as a spare. This allows for quick replacement in case of an outage and ensures 24/7 service.”

FinFerries will retrofit the same propellers on a third FinFerries vessel (Kuparovirta), by the end of the year.
