Seaway Load Prediction Algorithms for High Speed Hull Forms Available to Purchase

This paper documents the generation of several seaway load prediction algorithms for catamarans, trimarans, and surface effect ships based on available model and full-scale test data. Froude scaling laws are used for geometrically different ships for each ship and load type using first principles and empirically derived studies. Simple seaway load prediction algorithms are then developed and expressed as functions of ship displacement and various key ship particulars. These global load algorithms are quickly computed, making them suitable for preliminary or concept design studies. In some cases, algorithms were developed from a minimum amount of data, and it is anticipated that as more data is gathered in the future, these algorithms will be further refined. As the ship design progresses, more accurate but time consuming computational analyses and model tests are appropriate.
