| Summary: | A key design element in coastal structure is the environmental load which consists of wind speed, wave height, and current. In order to avoid platforms from being subjected to extreme loadings, the design should be above the extreme conditions, which is usually composed of tides and storm surges but could also include tsunami, el Niño, and other climate and geological effects. The extreme loads may be determined with the annual maxima and joint density distribution. Based on the study conducted, it is proposed that for a wind mean return interval of 100 years, the associated wave design is 10 years for all 6 platforms that are currently under study. These studies were conducted through all Malaysian water including Peninsular Malaysia Operation, Sabah Operation and Sarawak Operation. This paper help to provide the correlation of wind and wave as wave and current. In addition, the benchmark can be set up for the operational region of the operation. The interim guidelines will be useful to expect the joint densities in this area and it will benefits operation on optimization of current design cost and time completion with lighter platform design |
