LIGHTSHIP WEIGHT ESTIMATION OF WIND FARM SUPPORT VESSELS AT THE INITIAL DESIGN STAGE

Abstract

The issue of the determination of lightship weight estimates of wind farm support vessels (WFSV) is considered. The algorithm of determination of components of the lightship weight is suggested. The hull weight of the ships suggested to be calculated through the surface area of the principal structural elements using the parametrical model. The formula for calculation of weight and volume of the superstructures was obtained by making the 3D model of the superstructures of the most widespread projects of WFSV. Using the statistical data processing the dependences were obtained for the determination of engine, gearbox and waterjet weights, which are used in WFSV. The results of the comparative analysis of the lightship weight of WFSV are given.
