Advanced Method to Predict Wave Induced Loads for High Speed Craft

Objective



Objectives and content Hull structural damage sustained by modern high-speed ships in severe seas indicates a need to improve methods of safe structural design. One critical factor is the lack of a practical and, at the same time, sufficiently accurate method to predict wave induced load effects for modern high-speed ships. Classification societies provide formulas for safe design loads, however, these formulas mostly reflect service experience based on existing ships. Future designs should include larger ships for which not enough service experience is available to serve as a basis for establishing adequate design methods and rule improvements. In addition, hull structures for economically competitive high-speed ships are optimised against least weight.

Therefore shipyards should use design methods that incorporate numerical techniques for optimised sage structural hull design and classification societies have to establish guidelines for rule improvement. WAVELOADS addresses this important aspect by it responding with the development of such a method. The research will include strength analyses of representative hull structural configurations of high-speed ships and the development of a sufficiently accurate practical numerical technique to predict wave induced design loads. This technique will be validated by systematic model tests in a towing basin and by comparative computations with an advanced non-linear two-dimensional (strip theory) method. The research will conclude with the establishment of guidelines and recommendations for hull structural improvements and rule develop BE97-4406.
