Rocking Revisited 1: Rocking of a Singe Cube on a Breakwater Slope

Prototype single layer armour units on a breakwater slope are observed to break. To predict when breakage occurs, the objective of this research project is to obtain knowledge on, and measurements of the rocking behaviour and failure mode of single layer armour units. A single cube on a breakwater slope is subjected to investigations. An...

A combination of SWASH and Harberth to compute wave forces on moored ships

Moored vessels are subject to wave forces and moments at different frequencies, which induce motions of the body and can be transferred to the mooring lines and fenders. Under extreme forcing and vessel motions, dangerous line breaking accidents can occur or the ship movements can be simply too large to continue the on/off-loading process,...

Criteria for (un)-loading Container ships

Time matters in the world of container shipping. Every shipping company focuses on maximizing the use of its ships. This means maximizing the sailing hours and thus reducing the hours spent in ports For this reason shipping companies demand a turnover time of less than twenty four hours from the transhipment company. During these twenty four...

Computer simulation of the behaviour of an LNG carrier moored to an open jetty

In the design of oil and gas terminals Six Degree of Freedom (SDF) models are used to calculate the motions of the moored ship as well as forces in mooring lines. TERMSIM II (LNG) is one of those SDF-models, developed by MARIN under a Joint Industry Program with Shell as one of the main sponsors and users. Although the simulation programs have...

Klaipeda North Port: Feasibility study - Computer modelling

This report presents a study on an extension of the port of Klaipeda, Lithuania. The Klaipeda State Seaport Authority (KSSA) is in charge of the management and the provision of efficient hinterland connections. It considers increasing the depth to - 18 m CD at the quays necessary for attracting more cargo. This maximum depth is governed by the...
