Nowadays, more and more nearshore LNG terminals are beingbuilt as it offers easy access to vessels coming from deep waterand mitigates the risk by isolating regasification units from thecities. However, designing these terminals can be challengingin shallow water, as it is exposed to low-frequency waves whichcan excite the moored vessels at their natural periods. By lackof knowledge and adequate numerical simulation techniques,the effect of these low-frequency waves on the motions ofmoored vessels are unfortunately often ignored in the design.This is likely to result in an underestimation of the vesselmotions and terminal downtime. In this paper, a methodologyfor the design of terminals in a nearshore wave climate ispresented. The methodology consists of six steps which guidethe engineer from the definition of the deep-water sea states tothe calculation of the vessel motions and terminal downtime. Inan initial stage, computational efficient tools are used, with thelimitation that several approximations need to be made. In alater stage, more detailed but expensive methods are applied.The objective of this paper is to show how the developedmethodology can give insight in the expected downtime due tothe low-frequency waves in any nearshore moo
