For free-ships, this nonlinear part is responsible for the well-known drifting force. For a free ship, one could say that the sway, surge and yaw have zero frequency or infinite period.

The One Degree of Freedom and Continuous Beam Modelse, a uniform, horizontal cross beam on a fixed ocean structure is assumed to vibrate in all modes under random forces. In each case, the statistical vibration analysis follows a definite pattern. Since the steps are rather lengthy, it is often easy to lose sight of the design goals of such an analysis. These steps to be followed are summarized:

Cervical-Spine

Wind and Wind Loadingser wave and current excitation, it is useful to review many of the salient features of wind loadings for two reasons. First, there may be some structures for which the wind loadings dominate the loading pattern and second, many of the wind effects are also present in the case of surface water waves

Currents and Current Loadingsis occurs when the currents and surface gravity water waves have components which coincide directionally. Thus, since the drag force is usually taken to be proportional to the square (rather than the first power) of the fluid particle velocity, the resulting force, due in part to the coupling (cross
