Physical Experiments
In this project, two new series of wave tank tests have been conducted at the Kelvin Hydrodynamics Laboratory at the University of Strathclyde in Glasgow, UK, and at the State Key Laboratory of Coastal and Offshore Engineering at Dalian University of Technology in Dalian, China. Additionally, some previously gathered experimental data has been reanalysed to complement these studies.
Kelvin Hydrodynamics Laboratory Tests
We perform a new set of experiments in the large flume (76 m long, 4.6 m wide with a constant water depth of 1.8 m) at Kelvin Hydrodynamics Laboratory, the University of Strathclyde. A single fixed surface-piercing vertical cylinder with a radius (R) of 0.2 m was placed 35.3 m away from the wavemaker. Focused wave groups and random waves are generated following the JONSWAP spectrum (γ = 3.3).

State Key Laboratory of Coastal and Offshore Engineering Tests
This experiment was carried out in the multi-functional tank of the State key Laboratory of Coastal and Offshore Engineering of Dalian University of Technology. The tank is 54m long, 34m wide and 1.3m deep. The effective area is 45m long and 28m wide, and the maximum effective water depth is 0.7m. At one end of the pool is equipped with a multi-directional irregular wave maker developed by the laboratory. The wave maker is composed of 70 wave plates with a width of 0.4 m and a height of 1.0 m.
A single fixed surface-piercing vertical cylinder with a radius (R) of 0.125 m was placed 10 m away from the wavemaker. Focused wave groups and random waves are generated following the JONSWAP spectrum (γ = 3.3). In this experiments, various wave spreading conditions are investigated. In addition to uni-directional waves, the study also explores bi-directional waves, which are characterised by two crossing wave groups with identical wave amplitude and peak wave period intersecting at the focus point. Furthermore, the multi-directional waves in the experiments are generated using the Mitsuyasu-type spreading function.

Previous Experiments
Previous experiments were conducted at the Danish Hydraulic Institute in Denmark. A portion of this data has been shared and is available for reference on the CCP-WSI website.
