DISTRIBUTION OF WAVE FORCES ON STRUCTURAL PARTS OF OCEAN STRUCTURES

The wave excited force on a structural part of an ocean structure can be approximated by three components which are discussed in this paper: the undisturbed pressure force which is the force that arises from the pressure over the structural part in a wave that is not disturbed by that part (Froude-Krilov force); the inertia force which is the force that arises from the acceleration of the added mass of the structural part in a wave that is not disturbed by that part; and the damping force which is the force that arises from the damping, due to the structural part, of the velocity of water particles in a wave that is not disturbed by that part. The influence of each component on the total force will depend on the wave frequency and the form of the body. Also the influences of interaction effects between several structural parts of the body have to be considered.
