State of the Art

Smaller rudders e.g. for leisure boats are occasionally made of fibre-reinforced plastic (FRP), while large rudders for container ships and tankers with a size of up to 100 m2 are nowadays exclusively made of steel, resulting in high weights of hinges, shafts and supports, and correspondingly high loads and energy demands. Increased freedom of design of a composite rudder flap can improve hydrodynamic performance, lifetime and reduce maintenance cost. High loads and a lack of experience in production processes currently inhibit the use of advanced materials.


A high performance, multi-material rudder with a lightweight flap will be demonstrated, including its multi-material components, manufacturing, joints and joining technique. The solution will provide improved hydrodynamic design up to potentially adaptive flap shapes at equal production and reduced maintenance cost. The demonstration campaign will comprise real-life operational validation on board and maintenance/repair tests


Wide variety of rudders for different types of ships, including those not produced in Europe. Market potential for EU equipment suppliers, many of them small and medium-sized enterprises. 
Positive experiences will trigger applications of FRP e.g. for propulsion improvement devices and adaptive hull structures. Potential synergies to offshore, e.g. renewable energy devices.
