WAVE ENERGY CONVERTERS (FOR WAPS) 

Assumptions of the example:

​​

• Assumed (additional) mass ratio of StruFlex inverted pendulum Wave Energy Converters: 0.5%

• Assumed roll angle: 8 degrees (converted wave energy increases quadratically with the roll angle)

• Assumed inherent damping ratio of ship: 5%

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

​​​​​​​​​​

Ship 1:
