Abstract:
This paper presents wave measurement and wave climate prediction within
Peninsular Malaysia. Rayleigh and Weibull density functions were used to predict wave
heights. The total wave energy density was found to be 17.69 MWh/m within an average
year, whereas average wave power density varied from 0.15 to 6.49 kW/m. Furthermore,
more than 60% of the annual wave energy was caused by wave heights between 0.2 to 1.2
m. Waves with peak periods between 2 and 8 s accounted for more than 70% of the total
wave energy. The extreme significant wave heights were predicted, using Gumbel,
Weibull and Generalised Pareto distributions, as having return periods of 10 to 200
years for the same locations. The extreme significant wave heights varied from 2.6 to 3.4
m for the aforementioned return periods. The results of the present study will contribute
greatly to the design of ocean engineering projects.
