Abstract

When the water surface elevation exceeds the deck elevation and inundates the deck of fixed
offshore structures, the resulting loads which are known as wave-in-deck loading leads to a
step change in the loads acting on the structure. Given its importance, for predicting WID, a
number of approaches exist, such as the well-known drag formulation and Kaplan’s model.
However, an important shortcoming of these models is the large number of empirical
coefficients that ought to be obtained experimentally. A recently proposed model, known as
Lagrangian Momentum Absorption (LMA) scheme overcomes these limitations by basing it
upon the momentum dissipation that occurs during WID loading, removing the need for a large
number of empirically tuned coefficients. This model can incorporate the details of the
structure including its’ porosity.
