A Study of Breakwater Layout on the Basis of Marine Traffic Flow

Abstract

A mariner feels the shiphandling difficulty when the vessel onboard passes through breakwater. Until now, the shiphandling difficulty of the mariner has not been taken into account in the layout of a pair of breakwater. This paper reproduced such a situation that shiphandling is difficult enough by using marine traffic flow simulation, it is assessed by using ES Model which is a quantitative model for evaluating the difficulty of shiphandling arising from maneuvering a ship in the restricted or congested waters. The results are as follows. (1) The change in the layout of a pair of breakwaters has little influence on the shiphandling difficulty. (2) If the width between breakwaters is the same, the speed of a ship affects the shiphandling difficulty. (3) The increase of the width decreases the shiphandling difficulty.
