Swell and wave-groups at Saldanha bay

Mooring problems are one of the most important issues in port construction and port operation when harbours are facing the open sea. Operational standards usually define that cargo handling for large vessels is possible when significant wave height is below some level, i.e., 0.5 [m]. However, several ports have reported mooring problems when the...

The analysis of prototype measurements concerning the behaviour of moored ships in long waves

In the past decades several numerical models were developed to predict the behaviour of moored ships in waves. They are referred to as Six Degrees of Freedom models. These models need quite detailed input data. For the planning phase of a port or an offshore facility, a need has grown for a model which estimates the ship's behaviour and possible...
