FIRST HYBRID PROPELLED BY SCHOTTEL THRUSTERS

Tuesday, October 8, 2019 

CCN’s 31m motor yacht 'Vanadis' is the first hybrid vessel of its type propelled by Schottel azimuth thrusters.

Its propulsion system consists of diesel engines with in-line electric motors. The vessel was built by the Italian shipyard CCN and has already been handed over to its European owner. It will be deployed in Italian waters.

"Electric power is also making its way into the yacht sector," said Diege Michele Deprati, CEO of CCN. "An increasing number of customers wish to practice their passion for yachting quietly and emission-free. To achieve this, we have equipped the Vanadis with a propulsion solution from SCHOTTEL and a DC bus system from Siemens. We chose Schottel because of its high level of expertise and decades of experience in this field."

Vanadis is powered by two Cat C9.3 engines which drive the two 260kW Schottel Twin Propellers. These achieve a maximum speed of 12.5 knots, which drops to 8 knots when cruising in electric mode. Beyond a lower fuel consumption and a limited environmental impact, it enhances on-board comfort thanks to reduced noise and vibrations.

The craft is fitted with a set of lithium-ion batteries (175 kWh) which supply most of the on-board utilities. The vessel can thus remain at anchor at zero emissions for up to 17 consecutive hours and cruise at limited speed for up to 120 minutes, depending on the power load.

Each Schottel Twin Propeller is equipped with two propellers rotating in the same direction. This feature allows the power to be distributed over two propellers and thus reduces the load acting on each individual propeller. The result is an increase in efficiency and comfort when compared with systems incorporating just one propeller. The STP is thus suited as a propulsion unit for all vessels with design-related higher propeller loads.

Named after a goddess of Norse mythology, the all-aluminium vessel features a master cabin and two guest cabins to accommodate a total of six guests. There is a second pilot station located on the flybridge.
