Performance of a Jacket-Type Breakwater with Water Chambers in Deep Sea

Abstract

In comparatively deep sea, under which soft grounds exist and also comparatively long waves like swells attack, a curtain-walled breakwater has been adopted as a possible structure for simplicity. However, horizontal wave forces on such curtain-walled breakwaters become very large because of deep draft depth. For the economical construction of breakwaters in those deep sea ports, it has been newly proposed that a jacket-type breakwater with water chambers consisting of two vertical walls and one submerged horizontal plate. The effectiveness of a newly proposed breakwater has been examined extensively, especially focusing on the reduction rate of transmitted waves and wave forces.
