Ships operating in ice-covered waters may experience structural damage due to ice-induced loads. This can occur even though the ship structure is designed according to rules considering ice loading. The basis of these design rules can be empirical, e.g. measured loads from full-scale trials and observed damages or energy based, which is known as the Popov Method. The rules propose to apply the design ice load as a uniformly loaded rectangular pressure patch. This simplification is, however, not in line with spatial variations of local ice loads and does not account for high pressure zones directly. Therefore, this paper proposes a method for identifying a representative ice load distribution under consideration of local pressure maxima based on a spatial and temporal varying ice load sequence. This identified load is applied to an example structure and the response is compared to the response using a current rule-based patch load.
