چکیده

Container ships should only make very small horizontal movements at the berth for efficient (off) loading of containers. This is especially a concern in ports directly facing the open ocean, where high swells at sea can cause harbor oscillations and low-frequency surge motions of the ship. A Developed mooring unit, the MoorMaster™, which replaces conventional mooring lines is addressed here. The hydraulics of the system have a strong deducting effects on the motions of the moored ship. Measurements at a container terminal port have shown that the surge motion of container ships was reduced from an amplitude of 1 meter to an amplitude in the order of 5 centimeters, while using MoorMaster™ units. However before MoorMaster™ units can be installed with confidence in other (new) terminals and comparisons can be made with other mooring systems, the characteristics of MoorMaster™ units should be included in numerical models for motions of moored ships. This paper addresses the operation mechanism of MoorMaster™ units. MoorMaster™ units act in two different states that in this paper both of them are explained and the results are given in a series of figures.
