Oscillations of cylinders in waves and currents

This thesis contains the results of two research investigations conducted by the author, the first an exploratory investigation into wave induced vibrations, conducted at the British Hydrodynamics Research Association (BHRA), and the second a comprehensive investigation into the forces on cylinders oscillated in still water and inline with various currents, conducted at the River and Harbour Laboratory (VHL), Trondheim, Norway. Questions posed by the results of the first investigation were used in the formulation of the second, and results from the second led to a better understanding of the first.
