The topics reviewed in this volume explore the role of "Computations, Model Tests and Reality" in design, engineering and operation of ships and offshore platforms. Divided into four different sections the subject areas cover: Advanced Vessels; Station Keeping; Propulsor Hull Interactions; and Nautical Simulators. The present work contains 79 workshop papers and summaries as well as keynote addresses on the above topics. The contributions will prove indispensable for all those interested in the latest technologies involved in arriving at cost effective, acceptable, efficient, safe ships and offshore structures.
