WAVE ENERGY CONVERTERS 

Assumptions of the example:

​​

• Mass ratio of StruFlex Self-reacting inverted pendulum Wave Energy Converters (regenerative mass dampers): 0,5%

• Rolling angle: 8 degrees                                                (converted wave energy increases quadratically with the rol- ling angle)

• Inherent damping ratio of ship: 5%

• Adjacent graph:  wave-induced steady state ship oscillations with & without Struflex WECs (dampers)

2. Corresponding reduction in the amplitude of ship oscillations: 40%

• Minimize amplitude of oscillations:

1. Reduction in the amplitude of ship oscillations: 80% 

2. Corresponding peak converted wave energy: 480kW
