ON SEAKEEPING OF CONVENTIONAL AND HIGH-SPEED VESSELS

The focus is on numerical and theoretical seakeeping problems for conv entional and high-speed vessels. Wave-induced motions, accelerations a nd added resistance in waves of nonplaning high-speed monohulls and ca tamarans are discussed. Emphasis is on the interaction with the steady flow and transom stern effects. The ''cobblestone'' effect and the sp eed loss of a surface-effect ship (SES) in a seaway are discussed. The importance and possibility of predicting the influence of flow separa tion on the vertical motions of conventional ships are studied. Numeri cal methods that accurately describe slamming on hull sections are dis cussed. Correlations with published model test data for bow flare slam ming are presented.
