Theory and Design of Floating Wave Attenuators

Marina Design Pre-Conference Workshop (Registration Add-On):
January 14, 2020 from 9:30 AM - 12:30 PM

Join this three-hour session dedicated to the protection of marinas from storm waves and boat wakes. This is a constant and chronic need. However for a myriad of reasons — whether cost, environmental impact, or simply aesthetics — fixed breakwater structures are often not the preferred solution to the problem. Floating wave attenuators offer an alternative to these fixed structures but are not equivalent in all respects. Floating wave attenuators have very specific capabilities but, more importantly, have physical limitations in the range of site conditions in which they can be effective. While there are many examples of installations of floating attenuators throughout the world, there has been no reliable or generally accepted means to properly estimate the expected performance. Worse, there is very little documentation of the true performance.

This class, targeted largely to planners, designers and vendors of such systems, is intended to present the evolution of floating wave attenuators over the past half century, introduce the theory of wave attenuation, and present tools to estimate honest expectations for performance of such a system. These methods are the result of the merging of various theories that have been developed over time, and which did provide apparently reasonable estimates of true performance. They now appear and are published as the recommended methodology for evaluating floating wave attenuators. The course will then extend for the performance theory discussion to examine how to estimate forces on the floating pontoons. The class will be instructed how to design a simple but proper mooring system, whether it be pile restrained, catenary moored, or uses another technique.
