Submerged Floating Breakwaters

Journal of Offshore Mechanics and Arctic Engineering, 1991
In 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 ...

Tethered Float Breakwater

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-

Development of the Ihi Floating Breakwater

Coastal Engineering in Japan, 1979
ABSTRACTWith the advent of the era of 200-mile economic sea zones, the efficient utilization of coastal waters has increasingly been required. Accordingly, many various facilities for cultivating marine products as well as port and harbor facilities, which used to be installed usually in shallow water of a bay, are obliged to be hereafter installed ...

Port of Brownsville Floating Breakwater

Ports '01, 2001
The 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.

Dual pontoon floating breakwater

Ocean Engineering, 1997
The 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.

Wave interactions with a floating breakwater

2012 IEEE Colloquium on Humanities, Science and Engineering (CHUSER), 2012
The present paper describes the hydraulic performance of a newly developed floating breakwater in regular waves. Laboratory tests were conducted with the aim of determining the wave transmission, reflection and energy dissipation characteristics of the breakwater model under various wave conditions.

Assessment of floating breakwaters

Marine Behaviour and Physiology, 1992
Structures for wave attenuation, i.e. floating breakwaters, exist mainly as theoretical concepts. Research into floating breakwaters has a long way to go before a practical floating breakwater is developed. However, the demand for development of such structures has always been strong in the field of offshore engineering.

Dual floating breakwaters

Ocean Engineering, 1993
Abstract A numerical model is developed to investigate the behavior of a pair of flexible, floating breakwaters consisting of complaint, beam-like structures anchored to the sea bed. Each structure is kept under tension by a small buoyancy chamber at the tip, additional stiffness in each case is provided by mooring lines attached to the buoyancy ...

Dynamics of Cage Floating Breakwater

Journal of Offshore Mechanics and Arctic Engineering, 2005
Floating 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 ...

Floating Membrane Breakwater

Journal of Offshore Mechanics and Arctic Engineering, 1996
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.
