Summary on Grant Application Form |
|
Velocities and accelerations will be measured under extreme waves combined with currents using PIV and the results compared to high order wave theories. Hydrodynamic forces will also be measured on a model TLP. Velocity patterns will also be measured around the complete TLP model in high waves and currents, and extreme three dimensional sea states. This project is a collaboration between Glasgow and Edinburgh Universities. The dynamic response of TLPs to extreme waves in combination with shear currents will be investigated. Velocity and acceleration dsitributions under breaking, or near breaking, waves will be collected. Further tests will be carried out at Edinburgh on breaking waves combined with currents, utilising the particle image velocimetry flow mapping technique and existing velocity data will be further analysed to estimate accelerations. Tests will also be carried out in the towing/wave tank at Glasgow to evaluate damping coefficients in extreme waves. Velocities and acclerations measured by experiment will be compared to the high order wave theories of Dean and Chaplin and also to Peregrine's boundary integral time stepping technique. Techniques for adding shear currents will also be examined. The kinematics and damping coefficients will be used as input to time domain computer programs to be developed at Glasgow which will be used to predict the dynamic response of a test structure, specified by the steering committee. Sensitivity studies will be carried out to assess the importance of the different loading parameters.
