Abstract
The structural designs of high speed craft are typically based on classification society rules to attest to the owner, designer, crew, passengers, and the public that a minimum level of safety is provided. As the speed and size of the vessels increase, extrapolation of the class rules may not satisfy the designers’ need to fully quantify the safety margin in their new design. Application of the first-principles-based analysis of motions, loads and structural responses will aid in the evaluation of safety and raise the level of confidence in the vessel’s overall mission. This paper discusses the methodology of a multi-level approach to the assessment of motions and structural loads on a high-speed catamaran, which is designed to operate at 40 knots through sea state 4. This approach includes linear frequency-domain seakeeping analysis, non-linear time-domain simulations and comparisons with rule-based assessments. The added values of the direct analysis approach over the conventional rule-based design is discussed.
