Experimental low frequency mooring analysis of a floating offshore wind turbine

Previous research into floating offshore wind turbines consistently shows some manner of discrepancy between numerical and experimental simulations when it comes to low frequency forces and motions. A part of solving this issue is the generation of accurate data for the calibration and validation of the numerical models, needed because of the...

The Effect of Multiple Storms on the Stability of Near-Bed Structures

Pipeline covers on the seabed are called near-bed structures which are generally made of rip rap. The crest height of a near-bed structure is such that waves do not break over it. Near-bed structures are used to protect pipelines against fishing equipment, ship anchors, dropped objects and preventing destabilizing of the pipeline. There are two...

Damage on rock slopes under wave attack

The aim of this study is the particularisation of the accuracy margins for the determination of the damage level in the experimental plan proposed by Remon Kik at his thesis for the study of Notional Permeability of breakwaters “The experimental research of the permeability factor P”. The evaluation of the proposed technique took place by means...

Large scale stability tests on the Barcelona breakwater

For the planned expansion of the port of Barcelona, the existing breakwater needs to be extended with 1000 m. The design of the new section has to be optimized and for this purpose experiments were performed in the CIEM flume at the LIM/UPC in Barcelona. The design of the existing breakwater is used as an initial design. An other part of this...

Modelproeven op klei in de centrifuge

De Dienst Weg- en Waterbouw van Ri jk.swaterstaat en de Sectie Geotechniek. van de Technische universiteit Delft zijn gezamenlijk een onderzoek gestart naar de stabiliteit en het deformatiegedrag van weg- en di jklichamen. Daar veldonderzoek kostbaar en zeer tijdrovend zou zijn, is besloten om modelonderzoek te doen in de geotechnische...
