Schottel reports that its after sales team has carried out a modernisation exercise on two double-ended ferries operated by FinFerries.

Both vessels, capable of holding either 14 cars or up to 60 tons 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.

Schottel has installed its SRP 150 Rudderpropellers in each of the two ships. In one, the Hanhivirta, the Rudderpropeller was able to be installed in the existing well. Sister ship Mossala wad a signifivanty larger well, so required an adapter ring. 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.

The advantage of this retrofit is a higher degree of standardisation in its fleet – which reduces costs of spare parts and increases availability. FinFerries ordered an additional SRP 150 unit as a spare. This allows for quick replacement in case of an outage and ensures 24/7 service.

The standardisation exeaercise is continuing, with a third ferry, Kuparovirta, a sister vessel of Hanhivirta, scheduled to be retrofitted with the Schottel Rudderpropellers by the end of 2019.

Schottel says that vessels like those employed by FinFerries can have a lifetime 50 years or longer, which can present problems when replacement parts are needed quickly. Schottel’s warehouse in Spa can ship spare parts to customers worldwide within 24 hours of order placement. As an OEM, Schottel can guarantee availability of spare parts for the coming decades.
