Analysis of extreme wind wave based on weibull and fisher tippett I (gumbel) distribution

Abstract Extreme waves are an important factor in coastal structures both offshore and onshore structure design. However, due to the difficulty of measuring ocean waves, many areas still do not have measured wave height data. Data processing is required transform wind data into wind-wave value order solve this issue. This study aims analyze extreme based on from BMKG Panjang Radin Inten II stations. For analysis determination can be done by using Fisher Tippet Type I (Gumbel) Weibull methods. The result show that method gives higher than Gumbel method, with maximum percentage 43.04% at 2-year return period.
