Schottel will supply propulsion systems for six live fish carriers (LFC) delivered by Turkey’s Sefine shipyard to DESS Aquaculture Shipping
The 84.4m-long and 16m-wide vessels will feature a Schottel diesel-electric propulsion system comprising two rudderpropellers type SRP 360 FP (1,400-kW each) with a propeller diameter of 2.2m and two transverse thrusters type STT 1 CP (400-kW each) and feature Schottel’s proprietary Leacon sealing system.
The sealing system features separate seals on both the seawater and gearbox sides to ensure that, in the event of leakage, any seawater entering the system or any gear oil escaping from the system is collected in an intermediate chamber. This prevents water from entering the gearbox and oil from escaping into the seawater.
Schottel said the combination will ensure that the vessels achieve optimum propulsion efficiency and maximum manoeuvrability.
DESS Aquaculture Shipping’s Project & Development Manager Henrik Andre Larsen said manoeuvrability is a major requirement in the narrow fjords and small passages close to the fish cages that the vessel will operate in. “In order to be environmentally friendly, we also have to ensure that no oil escapes into the seawater. All in all, the systems from Schottel optimally meet our demands.”
In March, Sefine shipyard delivered Aqua Skilsøy, the third of six LFCs to DESS Aquaculture Shipping. All six LFCs have a live fish hold capacity of 3900m³, and will be assigned to long-term contracts for Norwegian seafood company Mowi ASA.
The series is set to be completed by April 2021.
Schottel is also supplying the propulsion for a new state-of-the-art heavy-lift crane vessel to be used in building offshore windfarms.
