... ABSTRACT Free decay tests are less onerous to carry out compared to experiments that include waves. These tests can also shed light on hydrodynamic characteristics of a device, such as added mass, stiffness and damping. This knowledge can then inform numerical models set up for the device...

... load cases, moored decay tests, and a pair of focused wave cases in both operational and extreme sea state conditions, the dynamic responses of this semi-submersible platform are evaluated. Furthermore, the reliability and accuracy of the adopted hybrid model are validated against the experimental...

.... Decay tests and focused waves are simulated in the numerical models, and these are compared to experimental results, using a 1:70 scale model of the system. Comparisons between the numerical models and physical experiments are made. Results of surge motion response and line tension are presented...

... Laboratory Ocean Basin at the University of Plymouth, UK. The test cases under consideration are (i) static equilibrium load cases, (ii) free decay tests and (iii) two focused wave cases with different wave steepness. The FOWT is modelled using a two-phase Navier-Stokes solver inside the OpenFOAM-v2006...

Roll decay tests were undertaken to obtain the roll period of two models (Container ship and Bulk carrier), with different CB, in calm water condition with zero forward speed. From the experiment, it was shown clearly that the roll period was affected...
