Abstract
The paper discusses methods for assessing the characteristics of the anchor equipment used by classification societies and standards for small and high-speed craft. It is noted that most of the existing rules are based on the choice of elements of the anchor arrangement through the "equipment number", which does not allow taking into account the features of non-standard types of ships. A method of direct calculation of the anchor mass based on the effect of storm conditions on the ship, considering the given geometry of the hull and superstructure, wind speed and current has been proposed, which allows for more reliable consideration of the features of ships of different types. Using the methods of a number of classification societies and the above mentioned method of direct calculation, comparative calculations of the masses of anchors for a series of single-hull ships have been performed. The specifics of the requirements for multihull ships have been touched upon. Conclusions have been drawn about the primary factors affecting the parameters of the equipment and ways to improve the Rules.
Keywords: anchor equipment, small craft, high-speed craft.
