PURPOSE: Safety of cargo transfers on boardships in terminals can be ensured by fastening free movements of the ships asmuch as possible. A mooring arrangement, consisting of mooring ropes, isgenerally used for the fastening process. Purpose of the mooring arrangementsis to keep ships at acceptable freedom of movement values against forces thatoccur under various environmental conditions. Due to these environmentalconditions, forces occur on the rigid bodies of the ships. Analysis of effectsof these forces on the ship mooring arrangement is called as mooring analysis.METHOD: In this study, the development andaccepted principles of the mooring analysis at the ship-port interface will beexplained based on the literature.FINDINGS: Mooring analysis can be static,quasi-static and dynamic. The related forces in the mooring analysis aresignificantly created by waves, winds, and currents. Secondly cause conditionsare 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 togetherand act as a resultant force and moment vector on the ship rigid body. Theresultant 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 analysiswill enable a safe mooring arrangement to be selected for ships held indifferent environmental conditions. New effects of changing environmentalconditions on the existing mooring arrangement can also be foreseen.Keywords:Port-Ship Interface,Environmental Factors, Mooring Analysis |
