The Evaluation of Merchant Ship Operability,
Abstract
In this study the concept of ship operability is defined and analyzed within the broader domain of ship seakeepability. The objective of the proposed methodology is to develop an approach for the analysis of candidate ships for a specific mission that takes account of the effect of environmental conditions of moderate severity. The current status on ocean wave spectra is reviewed. The application of linear system techniques to the ship motion problem is next discussed, and this is followed by a study of the propulsive performance of ships in regular and irregular waves. No attempt is made to rigorously formulate and interpret the latter problem in terms of nonlinear statistical theory but the need for such work is cited, especially in regard to wave-induced resistance, power plant and propellar performance and their interaction effects in random seas.
