| Breakwaters are
structures used to attenuate or eliminate waves.
They help create sheltered region to prevent damage
to shorelines, harbors and other natural or man-made
marine structure.
Floating Breakwaters has
been developed relatively recently. Some of the
advantages are:
- Floating
Breakwaters are less expensive than fixed
structures in deeper water i.e. > 10 ft. (Hales
1981).
- Floating
Breakwaters can effectively attenuate moderate
wave heights i.e. < 6.5 ft (Tsinker 1995).
- Poor soil
conditions may make Floating Breakwaters more
feasible to use than heavy rubble fixed
breakwaters (McCartney 1985).
- Floating
Breakwaters produce minimal interference on
Water circulation, sediment transport and fish
migration (Kelly 1999).
- Floating
Breakwaters can be easily moved and rearranged
in different layouts or transported to another
site (Hales 1981).
- If ice formation
a problem, Floating Breakwaters can be removed
from the site (McCartney 1985).
- Floating
Breakwaters are not as obtrusive as fixed
breakwaters and can be more aesthetically
pleasing (McCartney 1985).
Some of the
disadvantages are:
- Floating
Breakwaters are less effective in reducing wave
height for slow waves than fixed structures are;
a practical upper limit for the design wave
period in the range of 4 to 6 seconds (Tsinker
1995).
- Floating
Breakwaters are susceptible to structural
failure during catastrophic storms (Tsinker
1995).
- If the structure
fails and is detached from its mooring, the hard
structure
breakwater may become a hazard (Kelly, 1999).
- Relative to
fixed breakwaters, Floating Breakwaters
require a higher amount of maintenance
(Tsinker, 1995).

Application of Floating Breakwater |
|
|
Floating breakwaters are gaining in importance for the protection from severe waves nowadays simply because the are multi-functional structures. Floating breakwaters have many potential applications for boat basin protection and boat ramp protection. Presently, most floating breakwaters provide a degree of protection from short-period wind waves or boat wake at semi-sheltered sites in estuaries, reservoirs, marinas, lakes and rivers. A safe sheltered zone can be established at the lee side of the floating structure in order to meet both the environmental or commercial need at coastal areas.
Currently, the interest in floating breakwaters mainly comes from the military for construction deployable ports, from the pleasure boat market, and from expanding commercial harbours. Most of these sites will need some form of perimeter protection. Even a sheltered site will likely require some separation between the berthing area and the river or outlet to reduce short period waves and boat wash and keep out floating debris. Floating breakwater is the best solution to the problems. It can provide a versatile means of protecting any marina or dockage area as well as providing the best protection both from wind waves as well as wave created by boat traffic.
Besides, floating breakwaters also provide a certain extent of shoreline erosion control. They can reduce or prevent the costly consequences of lakeshore or seashore erosion. Floating breakwaters can also provide a protected area of water such as near beaches, and around constructed projects at nearshore or offshore from severe waves. Some of the floating breakwaters are found suitable to be applied as docks for mooring boats in non-storm condition, e.g. floating pontoon. For some practical uses, they can act as a swim area barrier, debris boom, etc. They can be useful even in the most unusual applications such as sewage ponds, etc., by simply helping to moderate the wave or providing accesses from one place to another |
