Abstract
Defence Research Establishment Atlantic has hydordynamic research interests for SWATH (Small Waterplane Area Twin Hull) vessels, which offer enhanced seakeeping capability and operational effectiveness with respect to monohulls of comparable displacement. Rough water trials were undertaken on the U.S. Navy T-AGOS 19 SWATH vessel, Victorious, between November 1992 and January 1993 as part of shakedown trails for the new vessel. In a cooperative venture the US provided DREA with slamming pressure data from the trials and, in exchange, DREA provided several large pressure transducers for use in the trials and agreed to analyze the data collected. The pressure peak data were colletd and grouped according to seastae, ship heading, and ship speed and Weibull distributions were developed. The resulting distributions, in general, showed slopes with values close to 1.0 indicating that the data follow an exponential distribution, as expected for slamming pressure data.
