Abstract
This paper extends and exploits a numerical method of calculation of the development of a wave approaching a fixed or moving body. The theory is strictly two-dimensional which implies that the body length is much greater than its breadth or depth, and that it lies parallel to the wave crests. Many wave energy devices of the terminator type, either mounted upon the sea bed or on rigid or flexible spines, satisfy these requirements and therefore the present method can be used to study their behaviour in extreme waves. This paper considers the general problem of forces and pressures on a circular spine section when exposed to a large wave, and also considers two specific examples, the “Clam” and an Oscillating Water Column (O.W.C.).
