Schottel reports that, at the request of the Damen Group, the Maritime Research Institute Netherlands (MARIN) has carried out extensive research to demonstrate the added value of the Schottel RudderPropeller Dynamic (SRP-D) for offshore wind commissioning service operation vessels (CSOVs). An earlier study had already demonstrated a reduced DP footprint and fuel savings, and this latest research focused particularly on propulsion efficiency during thruster interactions.

The results obtained, says Schottel, show a significant increase in thrust yield as well as reduced forbidden zones with the SRP-D compared to conventional rudder propellers.
