1. Shim, Sangyun. Coupled dynamic analysis of floating offshore wind farms.

Degree: 2009, Texas A&M University

During the past decade, the demand for clean renewable energy continues to rise drastically in Europe, the US, and other countries. Wind energy in the ocean can possibly be one of those future renewable clean energy sources as long it is economically feasible and technologically manageable. So far, most of the offshore wind farm research has been limited to fixed platforms in shallow-water areas. In the water depth deeper than 30m, however, floating-type wind farms tend to be more feasible. Then, the overall design and engineering becomes more complicated than fixed platforms including the coupled dynamics of platforms, mooring lines, and blades. In the present study, a numerical time-domain model has been developed for the fully coupled dynamic analysis of an offshore floating wind turbine system including blade-rotor dynamics and platform motions. As a test case, the TLP-type floater system with 3 blades of 70-m diameter designed by the National Renewable Energy Laboratory (NREL) is selected to analyze the dynamic coupling effects among floating system, mooring lines, and wind turbine. The performance of the selected system in a typical wind-wave-current condition has been simulated and analyzed. A similar study for the floater and rotor coupled dynamic analysis was conducted by MIT and NREL. However, in the present case, the dynamic coupling between platform and mooring lines are also considered in addition to the rotor-floater dynamic coupling. It is seen that the rotor-floater coupling effects increase with wind velocity and blade size. The increased coupling effects tend to increase the dynamic tension of TLP tethers. The developed technology and numerical tool are applicable to the new offshore floating wind farms planned in the future. Advisors/Committee Members: Kim, M. H (advisor), Randall, Robert (committee member), St?l, Achim (committee member).

2. Kuriakose, Vinu P. Floating LNG terminal and LNG carrier interaction analysis for side-by-side offloading operation.

Degree: 2005, Texas A&M University

Floating LNG terminals are a relatively new concept with the first such terminal in the world installed this year. The hydrodynamic interaction effects between the terminal and a LNG carrier in a side-by-side offloading arrangement is investigated. The side-byside arrangement is compared with each body floating alone to identify the interaction effects. The hydrodynamic coefficients are obtained using the Constant Panel Method and the analysis of body motions, mooring line tensions are done in time domain. The relative motion between the two bodies is analyzed using WAMIT in frequency domain and WINPOST in time domain to ascertain the offloading operability of the terminal under 1 year storm condition. Advisors/Committee Members: Kim, M. H. (advisor), Randall, Robert (committee member), Stoessel, Achim (committee member).

3. Adil, Adam Mohamed. Simulation of ship motion and deck-wetting due to steep random seas.

Degree: 2005, Texas A&M University

The extreme motion and load of ships have been assessed using a linear frequency domain method or a linear energy spectral method and RAOs, which may be too approximate to be used for estimation of ship motion in severest seas. The new technology uses simulation in the time domain to deal with the non-linear responses to the random seas. However, the current simulation technique has been successful only up to the sea state of 7 (?high seas?), defined by the significant wave height of 9 meters. The above cannot provide the extreme wave loads and motions for seas higher than the sea state 7. The ultimate goal of this work would be to develop a new technique that can simulate responses to the seas of states 8 and 9. The objective of the present study is to simulate the vertical relative motion and wave topping of a moored ship in the time domain by varying the significant wave heights. The analysis was able to predict with a fair accuracy the relative motion characteristics of a freely floating body in the head and beam sea conditions. The resonance aspects and its significance in the overall response are also analyzed. Advisors/Committee Members: Kim, C. H. (advisor), Stoessel, Achim (committee member), Kim, M. H. (committee member).
