Journal of Waterway, Port, Coastal, and Ocean Engineering, 1985
Floating breakwaters are inventoried. The various types are separated into 4 general categories, which are Box, Pontoon, Mat, and Tethered Float. The Tethered Float was identified as a special category but lacked sufficient prototype experience for detailed analysis. Advantages and disadvantages of the Box, Pontoon and Mat are presented.

Submerged Floating Breakwaters
Journal of Offshore Mechanics and Arctic Engineering, 1991In this paper we show how a submerged body can, if properly tuned to the incoming waves, reflect an appreciable amount of the incident wave energy by creating waves through its own motion which effectively cancel the incident waves passing over it. A general theory for this phenomenon is described which is applied to the cases of a hinged vertical ...

The hydrodynamic properties of a pair of long floating pontoon breakwaters of rectangular section are investigated theoretically. The structures are partially restrained by linear symmetric moorings fore and aft. The fluid motion is idealized as linearized, two-dimensional potential flow.

Journal of Waterway, Port, Coastal, and Ocean Engineering, 1985
An analytical model is developed to examine the response and efficiency of a rigid, hinged floating breakwater. The theoretical model is verified experimentally and is used to develop design curves which may be employed to estimate necessary physical breakwater characteristics to satisfy specified wave attenuation criteria.

Dual pontoon floating breakwater
Ocean Engineering, 1997The hydrodynamic properties of a dual pontoon floating breakwater consisting of a pair of floating cylinders of rectangular section, connected by a rigid deck, is investigated theoretically. The structure is partially restrained by linear symmetric moorings fore and aft.

OCEANS '79, 1979
This paper presents the Tethered Float Breakwater (TFB) which was developed as part of the Navy's Container Offloading and Transfer System (COTS). COTS provides fleet logistic support for sustained operations that include at-sea cargo transfer in unprotected areas having sea-states up through 4. With the TFB, a portable wave attenuation system, the sea-

Abstract The hydrodynamic properties of a flexible floating breakwater consisting of a membrane structure attached to a small float restrained by moorings are investigated theoretically. The tension in the membrane is achieved by hanging a clump weight from its lower end.

Port of Brownsville Floating Breakwater
Ports '01, 2001The technical aspects of a new floating breakwater concept installed at the Port of Brownsville Marina, located in Port Orchard Bay, Washington, are described in this paper. The breakwater incorporates submerged porous treated timber "wave fences" installed on either side of the concrete pontoons to reduce wave transmission.

Performance of Cage Floating Breakwater
Journal of Waterway, Port, Coastal, and Ocean Engineering, 1997Conventional floating breakwaters are examined and the feasibility of developing a cage floating breakwater is explored. Earlier studies on floating breakwaters reveal that, to achieve a transmission coefficient (\iK\i\dt) less than 0.5, the breakwater width to wave length ratio (\IW/L\N) should necessarily be greater than 0.4 for most of the ...

Dynamics of Cage Floating Breakwater
Journal of Offshore Mechanics and Arctic Engineering, 2005Floating breakwaters have potential applications in protecting minor ports and harbors such as fisheries and recreational harbors, where-in stringent tranquillity requirements are not warranted. In field applications of the existing floating breakwaters, limitations are imposed due to their large relative width (ratio between breakwater width and wave ...
