Economics of scale act as driving force for the construction of Ultra Large Container Vessels (ULCV). The biggest advantage of container vessels is fast loading and unloading of containers. Large motions of the moored vessel along the quay hamper this process and even cause safety issues. This paper focusses on modelling the behaviour of moored vessels under ship passages, using a two-step approach. The forces acting on the moored vessel are modelled using RoPES (PMH), the behaviour of the moored vessel is modelled using the Ghent University in-house time domain software Vlugmoor. In a first part, four validation cases are presented, based on GPS measurements performed at the North Sea Terminal in the port of Antwerp, where the moored vessel is a Neo-Panamax container vessel. In a second part, the mooring plan of the vessel is discussed in detail. Both on the level of the individual lines, as well as for the mooring plan, efficiency parameters are defined. These parameters express the capability of a mooring plan to deal with longitudinal and transversal forces, based on line angles and line lengths.
