The company, formerly Volda Mekaniske Verksted, was established in 1913 in Volda, Norway, and was taken over by the Scana group in 1998. Today Scana Volda is a recognised supplier of propeller systems to the international market.
The latest in the company’s product development and cooperation is a contra rotating propulsion system. This system is controlled independently in a dual shaft line by two high efficient permanent magnet motors. Contra rotating propellers are in their nature more efficient than similar single propellers. Motors directly connected to the propellers gives fewer components, and improved energy conversion make the solution more efficient and safer compared to the benchmark in the marine industry.
Orders
Scana Propulsion recently delivered the first out of three twin screw propulsion systems for Aker Seafoods’ advanced stern trawlers. The new diesel electric trawler design with twin screw solution is designed with high focus on fuel efficiency, low noise emission and environmental performance. The selected twin screw arrangement ensures excellent fuel efficiency performance during trawling compared to a single screw arrangement. The first vessel, Gadus Poseidon, will be the first fishing vessel in the world with the new Silent–F notation from DNV. Scana Propulsion has specially designed the propellers for low noise emission to achieve this class notation.
Scana Propulsion has also signed a contract with MAN Diesel & Turbo SE for a ACG 1080 2-speed gearbox incorporated with a MAN diesel engine for a fishing vessel to Norwegian owned Birger H. Dahl AS.
The 2-speed reduction gearbox offers great flexibility and considerable cost savings to the owner. The system satisfies the requirements to safety in emergency situations and redundancy in propulsion. In a situation where the main engine has to be stopped as a consequence of main engine breakdown or maintenance, the PTI function could be used in ‘take me home’ mode, by disengaging the main engine and running the ship via the shaft generator as electric motor. With this configuration the system can also run in a hybrid solution, engaging the main engine and electrical boost at the same time, giving maximum power to the propeller.
The vessel will be built at Karstensens Shipyard, Denmark.
