PREDICTIONS OF MOTIONS, LOADS AND STRUCTURAL RESPONSES INDUCED BY WAVES

The prediction of wave-induced motions and loads is essential in the design and structural analysis of ships and other floating structures. The fact that ocean waves are irregular and wave conditions ever-changing, calls for a statistical (probabilistic) description of the waves and the wave-induced motions and loads. The fundamental idea of probabilistic description of linear systems is now widely accepted as the rational basis for design. Det Norske Veritas research into such methods has led to the development of a set of computer programs designed to handle different categories of structures, basically following the same three steps:-- Response to regular waves. Determination of motions and loads in regular waves of various lengths and unit magnitude, presented in the form of transfer functions. These give the same information as can be obtained from model tests in regular waves. Response in given sea state in irregular waves. Combination of transfer functions and sea-state information to obtain the response characteristics. Prediction of long-term response. A diagram of wave-load and related programs for marine structures is included. Order from BSRA as No. 49,223.
