Abstract Prediction of maximum wave height and the relative period as the fundamental parameters for assessment and design of offshore structures are forced with uncertainties. This paper proposes two algorithms for calculation of the probable extreme wave height in the Persian Gulf with respect to existing statics data in the South Pars region. A long-term joint distribution model of the corresponding wave height and wave period is needed in first manner and in the second model, a joint density function is defined in terms of a marginal distribution and a series of conditional density functions. Furthermore a relation is proposed for calculating of the period based on monthly and yearly data of the region. Finally some curves will be derived which may be used for estimating annual exceedance probability of maximum wave height for life time of offshore structures.
Keywords: significant wave height, maximum wave height, zero-up crossing, period, lifetime, Persian Gulf
