MATHEMATICAL ANALYSIS OF SHIP MOORING SYSTEMS AND COMPARISONS WITH HYDRAULIC SCALE MODEL INVESTIGATIONS

This paper illustrates the use of a computerized simulation model which has been developed to calculate wave induced ship motions and mooring forces for vessels moored in exposed locations. Ship mooring facilities at one existing and one proposed oil terminal installation on the eastern seaboard of Canada have been analyzed with this computer model. The results of these studies have been compared with those of hydraulic scale model investigations previously completed by other agencies. The results of the comparative mathematical and hydraulic model studies presented in this paper include a summary of simulation tests for alternative mooring arrangements, mooring line types, line pretension loads and varied sea state conditions. The maximum vessel motions and mooring forces resulting from regular waves and from slow drift oscillations generated by wave group formation in irregular sea states are evaluated and discussed.
