港湾における錨地配置設計に関する研究

Abstract

When the configuration of anchorages in harbour is designed, the shiphandling difficulty which is imposed on a ship navigating between the anchored ships should be considered. However, no research work has been done about the method to fix quantitatively the design elements of the configuration of anchorages under the condition that the shiphandling difficulty comes to an allowable level. The relationship betweeen the configuration of anchorages and the shiphandling difficulty was analyzed by applying the Environmental Stress Model as introduced in the previous paper. In the present paper, an algorithm to design the configuration of anchorages in harbour under the condition that the shiphandling difficulty comes to an allowable level was investigated. And a computer aided supporting system to design the configuration of anchorages was developed taking into consideration the userfriendly interface through graphical information on CRT display. It is avairable by using this system to select an alternative of the configuration of anchorages that the condition of the sizes of anchored ships and the shape and area of anchorage can be taken into consideration.
