WAVE INTERACTION WITH A SUBMERGED OPEN-BOTTOM STRUCTURE

The interaction of sinusoidal waves with a large open bottom structure near the ocean floor is investigated. The wave diffraction problem is formulated within the framework of linearized potential theory and solved numerically on a digital computer. The analysis is confirmed by the results of wave tank tests on a hemispherical shell and underwater storage tank models. It is found that both the horizontal and vertical forces acting on an open structure are lower than those on the corresponding sealed structure, the vertical force, in particular, being an order of magnitude smaller over the practical range of wave periods. The inside pressure on the structure when slightly open correlates very well with the mean bottom pressure on the structure when sealed, so that the results for the slightly open case can be obtained from the results for the sealed case.
