Recent Research on Wind Loading [and Discussion]

The paper reviews some of the research carried out over the past ten years into the effect of wind on vessel rolling and capsize. Two main techniques are discussed: the so-called discrete gust, where a vessel at its extreme windward roll angle is acted upon by a sudden increase in windspeed, and the stochastic approach, where the steady-state response to a random sequence of wind pulses is calculated. Some model experiments in a wind-wave tank are also described and compared.
