The experimental set-up allows for the comparison of two different ballast options of a floating cylinder in a wave tank. Four different internal water drafts are tested as well as an equivalent solid ballast option. The model is excited by regular waves which are characterised with five wave gauges in front of the floating cylinder and two behind. Additionally, the time series of the six-degree of freedom response of the floating structure is made available. Regular waves with an initial amplitude of 0.05 m and frequencies over the range 0.3 to 1.1 Hz are investigated. This results in a wide range of different responses of the floating structure as well as very big rotations of up to 20 degrees. This data-set allows for identification of the influence caused by the sloshing of the interior water volume and can be used to validate numerical models of fluid-structure-fluid interaction. This research was carried out at the FloWave Ocean Energy Research Facility of the Institute for Energy Systems, University of Edinburgh.
