WIND DIRECTIONALITY FACTOR ON OFFSHORE PLATFORM IN MALAYSIA WATER

In designing offshore structure, wind load are being considered as one of the load that are acting on the topside platform. The ASCE 7-10 equations specifies on how to calculate the wind pressure based on some factor, where wind directionality is one of them. This research is focusing on the suitable factor to be used based on the conditions of Malaysian water, which is the South China Sea.
Measured wind data collected at three different locations across the Malaysian water is taken into consideration in this research. These data will give the pattern of the wind that blows across Malaysia, which will be influenced by the monsoon season in Malaysia, namely the southwest monsoon and the northeast monsoon. These monsoons will influence the direction of the wind that will be acting on the platform.
