Abstract

Unreliability of measured meteorological and oceanographic (metocean) data happens due to missing data as a result of faulty measuring equipment during the measuring process. Therefore, SEAFINE hindcast model data is introduced as an alternative to measured data. SEAFINE is readily available, parametrically reliable and is able to provide long periods of historical metocean data. Therefore, SEAFINE becomes a common tool to assess metocean information at any locations especially in the South China Sea. However, SEAFINE is found to be not as accurate as measured data. The accuracy of the SEAFINE is improved and correction factors are recommended for three (3) operating regions located in Malaysian waters which are Peninsular Malaysian Operation, Serawak operation and Sabah Operation. The findings presented herein found that wind speeds determined from the SEAFINE are generally higher than measured ones. Wave height data obtained from the SEAFINE is found to agree well with that of measured data. The correction factors for both SEAFINE wind and wave data are recommended. The adjustment factor reflecting the 95% confidence intervals are adopted to interpret SEAFINE wind and wave data.
