Особливості розрахунку економічних показників високошвидкісних лоцманських катерів на етапі концептуального проектування

Abstract

During the last decades a vast amount of research has been focused on the issues of design, operations, and development of more optimized structures of high-speed craft. The right choice of the criterion function is crucial. Fundamentally, efficiency can be increased with the reduction of production costs, operational costs, and environmental impact, while maintaining or improving craft performance, reliability, and safety. The estimation of economic performances of pilot boats in conceptual design phase should account for many features, such as, different building materials, development of the hull design, choice of the propeller, conditions of operations, and others. The majority of estimation techniques are developed specifically for large ships and, therefore, do not take into account the essential features of design and function of small high-speed craft, namely, pilot boats. Іn this paper we present formulas for estimation of building cost of the conventional pilot boat (a monohull). The author recommends the set of formulas for estimation, which form the mathematical model. These equations can be used in the optimization task.
