DESIGN ALGORITHMS FOR PRIMARY AND SECONDARY LOADS ON SWATH SHIPS

The scantling of SWATH ships must be designed to withstand the primary and secondary loadings imposed by the seaway. These loadings are not as well known for SWATH ships as they are for conventional monohull ships. Previous studies used Froude scaled response characteristics from model tests to predict the maximum lifetime primary loads. Design algorithms were developed from these studies for ships in the 3,000 to 30,000 ton range. Lacing comparable guidance for smaller ships, these algorithms have frequently been misapplied to smaller vessels. This paper extends the previous method and develops primary load algorithms for ships as small as 50 tons. Also presented are algorithms for predicting the slam impact pressures for SWATHs in the 50 to 30,000 ton size range.
