Analysis of SWATH Ship Structures
Keyword(s):
Three methods of analysis of the primary structure of SWATH ships are examined. The quasistatic, rigid-dynamic and hydroelastic approaches are applied to analyze the structure of a detailed SWATH design. Deflections and stresses are calculated after each method and compared. The convergence of the hydroelastic approach with respect to the number of modes is also investigated. Although a relatively small ship is considered in this comparative study, hydroelastic effects are shown to be significant in areas of greater flexibility.
