How to use it
- Enter significant wave height and period.
- Review or adjust seawater density.
- Calculate power per meter of crest.
Wave Energy Calculator
Estimate deep-water wave power per meter of wave crest using a simplified approximation.
Important: This calculator is an educational estimate only. It is not marine navigation, voyage planning, vessel, diving, rescue, flood, storm, coastal, offshore, pressure-vessel, engineering, legal, or safety advice.
About the Wave Energy Calculator
Use a standard simplified deep-water expression as an educational power indicator.
Approximation
Power per crest width is density times gravity squared times wave height squared times period, divided by 64 pi.
Example
A 2 m wave height and 8-second period at 1,025 kg/m³ gives an indicator near 15.7 kW/m.
Notes
Real spectra, direction, depth, losses and device performance require coastal or offshore engineering analysis.
