Designing Ships to the Natural Environment
Abstract
Until recently, the natural environment has played a very minor role in ship design. The consideration of ship performance in the prevailing environment was focused primarily on optimization of calm water resistance and other factors related to the ship's propulsion system. During the 1970's, the Navy recognized the need to 'design in' better ship performance and initiated the R&D efforts necessary to establish a technology base for doing so. This paper outlines the state-of-the-art for environmental (primarily wave) modelling in the emerging seakeeping performance oriented design procedures. The sensitivity of the ship system to the environment is briefly examined. A standard procedure for specifying wave and wind conditions for ship design is recommended. Revision of U.S. Navy applied Sea State numeral definitions is discussed. A standard for specifying Sea State occurrences is offered as a new design tool. (Author)
