PURPOSE: Safety of cargo transfers on board ships in terminals can be ensured by fastening free movements of the ships as much as possible. A mooring arrangement, consisting of mooring ropes, is generally used for the fastening process. Purpose of the mooring arrangements is to keep ships at acceptable freedom of movement values against forces that occur under various environmental conditions. Due to these environmental conditions, forces occur on the rigid bodies of the ships. Analysis of effects of these forces on the ship mooring arrangement is called as mooring analysis.
METHOD: In this study, the development and accepted principles of the mooring analysis at the ship-port interface will be explained based on the literature.
FINDINGS: Mooring analysis can be static, quasi-static and dynamic. The related forces in the mooring analysis are significantly created by waves, winds, and currents. Secondly cause conditions are most likely case-port specific, and can be listed as passing ship effect, tide effect, gust effect and port-based events. All these forces work together and act as a resultant force and moment vector on the ship rigid body. The resultant force vector is covered by the mooring lines at different rates, depending on physical and angular properties of the selected line.
CONCLUSION: A properly done mooring analysis will enable a safe mooring arrangement to be selected for ships held in different environmental conditions. New effects of changing environmental conditions on the existing mooring arrangement can also be foreseen.
