Tidal Flow Separation at the Sand Motor

This study investigates the existence and character of tidal flow separation at the Sand Motor, a mega-scale sand nourishment at the Delfland coast. Tidal flow contracts at the tip of the Sand Motor, downstream the tip the flow diverges and flow separation could occur. In case of flow separation the diverging streamlines cannot follow the...

Manado: A Developing Coast

Manado, the capital city of North Sulawesi in Indonesia, is rapidly developing. The last years Manado has been extending into the sea, which changed the hydraulics and morphology of Manado Bay. This had negative effects on the currents, inducing erosion along the coast. Also Manado has problems with the presence of garbage in the rivers and...

The use of Elastocoast in breakwater research

In this report will be explained how breakwaters can be made with the use of Elastocoast, a sort of glue. This makes it possible to fix the individual rocks, and allows repetitive tests possible with exactly the same layer properties. We made six samples of breakwater rock layers, made with Elastocoast and stones, which can be placed and tested...

Schematization of Hydrodynamic Forces Acting on Jack-up Legs and Morison Coefficients for Jack-up Legs

The first report is about: A jack-up rig is a mobile offshore platform. Basically, it is a self-elevating pontoon, which can be supported by retractable legs resting on the sea bed. Recently, it is proposed to use these platforms for production of marginal fields, what implies a longer term use. Furthermore, there are plans to use such platforms...
