ASSESSMENT OF WAVE ENERGY RESOURCES IN THE VICINITY OF NATUNA ISLANDS

The objective of this work is to study the wave energy resources and selection of conversion technologies options in the vicinity of the Natuna Islands. This study involves analyzing the wave characteristics of the area and the theoretical wave energy resources currently available and estimating the electricity production of three types of wave energy converters (attenuator, terminator, and point absorber). The 59-year wave data were obtained from the SEAMOS-South Fine Grid Hindcast (SEAFINE) and statistical analysis was performed to obtain probability of occurence of the wave height and wave period, which describe the sea states. The seasonal variations of the wave characteristics were identified. The wave statistical analysis and estimation of energy production were analyzed on a monthly basis. The performance characteristics are provided for selected wave energy converter types, where the performance is a function of the sea state conditions. The incorporation of the probability of occurrence of sea states and performance of the wave energy converter show the highest estimation of electricity production occur during North East Monsoon season, and the lowest one during South West Monsoon season.
