Analysis of manoeuvrability criteria and standards in view of environmental factors and EEDI impact

A review and analysis of most significant earlier proposals on ship manoeuvring criteria are presented with the emphasis made on comparative significance and interconnection of inherent and environment-dependent criteria. It is demonstrated, mainly by means of plausible reasoning, that, besides possible toughening of the existing IMO standards based on purely inherent criteria for the turning ability and directional stability of ships, the only necessary additional criteria should be associated with the wind action and aerodynamic properties of the above-water part of the hull. A possible rational approach to formulating manoeuvrability criteria accounting for EEDI requirements is presented. A detailed review of former proposals of Authors of papers to proceedings have to type these in a form suitable for direct photographic reproduction by the publisher. In order to ensure uniform style throughout the volume, all the papers have to be prepared strictly according to the instructions set below. A laser printer should be used to print the text. The publisher will reduce the camera-ready copy to 75% and print it in black only. For the convenience of the authors template files for MS Word 6.0 (and higher) are provided.
