Three-Dimensional Analysis of Hydroelastic Behaviors of an Aircushion Type Large Floating Structure

This paper describes theoretical formulations for a prediction of hydrodynamic forces on the aircushion type large floating structure and shows corresponding results. Therefore, a new program code is developed. The structure is supported by large mono-aircushion. The present theory is based on the three-dimensional singular point distribution method. Effect of the aircushion is considered in this. Then, a processing of a singular integral of the boundary integral method is shown and its validity is confirmed. In conclusion, the draft effect to the pressure within the aircushion is discussed. As a result, when width of the skirt is thin, the draft effect is little. However, in case that the width is large, the draft effect is enlarged.Copyright © 2005 by ASME
