Abstract
A general methodology for the assessment of the inherent manoeuvring characteristics of ships, is presented. The methodology, which takes into account the non-linear nature of manoeuvring motion, is built on a specific set of manoeuvring requirements, translated into suitable criteria and measures of performance. These are later integrated in a hierarchical procedure which allows for combining effectively conflicting characteristics and producing a picture of overall manoeuvring capability. The problem is established as a typical decision problem in the presence of multiple objectives and conflict, with the first part of the paper devoted to the theoretical foundation of the general assessment model. Application is undertaken for the case of ferries, with consideration of a wide range of design parameters. As a result of this, areas of good or poor manoeuvring performance are identified. A clear distinction is made between the need to turn in limited space and the need to respond quickly to rudder commands. The methodology can be used in early ship design as well as in developing/optimising vessel type-specific manoeuvrability standards.
