EFFECT OF WINDSPEED TO WAVE HEIGHT ON CONTINENTAL SHELF MALAYSIA

Correlation between wind speed and wave height need to take into consideration when
designing offshore platform in order to optimize the usage of the platform material and
optimize the operational period. In this study, the wave characteristic effected by wind
generation is determined by using descriptive statistics analysis. The result of the
correlation were then being analysis to know the sea development state in Continental
Shelf Malaysia by comparing ratio of significant wave height with respect to the
corresponding wind speed with each calculated significant wave height from P-M
Spectrum Model, JONSWAP Spectrum and NALL Spectrum. The MetOcean Data
recorded at three (3) operating regions located in Malaysian waters which are
Peninsular Malaysian Operation, Sarawak operation and Sabah Operation were used
in order to make a realistic descriptive correlation between wind speed and wave
height. The finding were also compared between seasonal monsoons and non-seasonal
monsoon to make a comparable analysis of the different between the monsoons on the
Continental Shelf Malaysia. From the analyzes results, calculated significant wave
height form NALL Spectrum Model and JONSWAP Spectrum Model shows lowest
ratio with respect to the ratio of SEAFINE MetOcean data.
