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.
