Validity of a Strip Theory -Linear Superposition Approach to Predicting Probabilities of Deck Wetness for a Fishing Vessel.

摘要

The motions and ship-to-wave relative motions of a fishing vessel in head, regular waves are determined from a model experiment and from strip theory computations. The experimental results indicate that linear superposition is not universally applicable to the fishing vessel investigated. Correlation between the experimental and strip theory results is never excellent, and becomes extremely poor at the higher speed considered. The invalidity of linear superposition and strip theory found for the fishing vessel is shown to produce gross errors in predicted deck wetness probabilities. (Author)
