This chapter is devoted to ocean wave mechanics and wave forces acting on offshore structures. It contains eleven sections. The first section gives general information on ocean waves. The second section summarizes wave theories with emphasis on Stokes and other nonlinear wave theories. In the third section, the Airy wave theory is explained in more details and the formulation for deep water conditions is presented. The fourth section describes stochastic ocean waves, transfer functions, commonly used spectral functions of sea states and the directional wave spectrum. The fifth section presents the wave–current interaction phenomenon and the sixth section is devoted to probabilistic description of sea states in the long term. The seventh section presents formulation of wave forces on structural members. The eighth and ninth sections present linearization of wave forces under wave–current and wave–structure interactions. The tenth section, gives formulations of consistent member wave forces, member added mass, and hydrodynamic damping ratios. The eleventh section presents illustrative examples.

Water Wave Theories and Wave Loads

Optimization techniques are widely applied to determine the optimum solution of structural design problems. This chapter introduces first the mathematical formulation of optimization problems and then gives summary of the techniques available in obtaining their solution. There are several algorithms, some require the gradient information of the objective function and constraints and some other use heuristics to search the design space for the optimum solution. Among these algorithms, sequential programming technique and differential evolution algorithm are briefly explained. This chapter demonstrates second the mathematical formulation of optimization problems including the uncertainties associated with the loads, resistances, and structural responses and then offers summary of the techniques available to obtain the solution. The chapter ends with the application examples and exercises.
