PHYSICAL MODELLING AND DESIGN ASPECTS FOR A NEW MEGA-YACHT MARINA

Abstract


Extensive preliminary studies and a large-scale 3D physical model study were conducted to support the design of a proposed mega-yacht marina project at Bridgetown, Barbados. A faithful reproduction of the marina, the surrounding bathymetry, and the adjacent shoreline was constructed and used to gauge the performance of the marina in a range of operational and extreme seastates, and to enhance and verify the preliminary designs. The physical model was used to investigate many key issues including: wave agitation within the marina, wave overtopping, wave impact forces, the stability of revetments and scour protection stone, and the behaviour of moored yachts. Notable outcomes of the study included the optimal length and crest elevation along the curved breakwater, the strategic positioning of two piers and a revetment within the marina basin, and the determination of suitable design loads for various breakwater components.
