Generic Design of V-Shape and Vane-Type Breakwaters to Reduce Green Water Load Effects on Deck Structures and Containers of Ships: Case Study

Abstract

Using computational fluid dynamics as the key tool for analysis, this paper looks into the generic designs of two popular types of breakwater, i.e., V-shape breakwater and vane-type breakwater. These are common practices to prevent the intrusion of green water deep into the deck and to protect deck structures and containers from direct impact loading. A hydrodynamic model to present green water flow on deck is also summarized together with brief validation for its appropriateness. The geometrical parameters of these two breakwaters are systematically varied and the effects on their performance against green water are evaluated. The effectiveness of coping with green water loading of each type of breakwater is also analyzed and compared.
