Wave energy damper

A system of the active coast’s protection, coastal and hydropower facilities protecting from the storm impact, that creates the interference
of incident and reflected waves and converts destructive wave energy into the useful work. System can be placed on the existing and the
newly created coastal facilities. With its help it is possible to protect the coast line from the storm impact without capital hydropower
structures.
Unite two technologies : technology of creating the protective structures and
technology of converting destructive wave energy into the useful work
(electricity).

Has the unique automatic management system that calculates the wave impact's
power, operatively changes physical parameters of working elements, increases
or reduces damping and also redistributes electrical load. This system equally
works with different wave parameters.

All the developments are protected by the portfolio with 4 patents for
the invention of the Russian Federation, 2 patents for the useful
model, 2 international applications of PCT were submitted and
realized.


The main advantages of the wave energy damper in
comparison with analogues
None of the known prototypes is not a fully protective complex, while the wave
energy damper unites two technologies: technology of creating the protective
structures and technology of converting destructive wave energy into the useful
work.
- Wave energy station that consists of the group of dampers allows reducing the
building cost of the protective structures in 6 – 10 times and also converting
about 45 % of the initial wave energy into the useful work; the total wave energy
can be reduce in 7-10 times. Thus the wave energy almost completely looses its
destructive potential.
- The energy damping device has an automatic management system and
depending on the wave impact’s power and angle of approach of waves to the
shoreline , operatively changes physical parameters : displacement, mass; and
also distributes the load on the generator that allows working on the waves of
different heights and frequencies of the period reliably and with high efficiency
- The wave energy damper is much more reliable than analogues and allows
emergency and maintenance works in storm conditions because it has the system
of the radical reduction of the wave loads above the estimated.
- The working device has no hard connection with the ramp; in contrast to the
known analogues has no limits of moving therefore it works equally with the
different heights of waves and changes of the water level in case the ebb – and-
float.

Economic parameters and the field of utilization of the wave
energy damper.

1. The newly created hydro power facilities by the technology of the supporting waffle-crete log booms.
Creation of the bank protection structures using the wave energy damper and technology of the supporting waffle-crete log booms allows reduction of the
building cost in 8 – 10 times. Using the traditional building methods 1 running meter of facilities with depth 7-10 meters and waves height 7.5 meters
costs about 300 000$. To build with our technology you will need 36 000$. At the same time 45 % of the initial wave energy converts into the useful
work. Preliminary calculations show that it’s possible to get about 6 -10 millions kW/h of electricity per 1 year from the Black Sea coast.
2. Protection of existing hydraulic structures.
Using the wave power damper on existing hydraulic structures( (wave breakwaters, enclosing dams) allows you to continue the lifetime of such structures, to
reduce the cost of repair and reconstruction is 1.5-2 times, and also to sell produced “green” energy on the local market, getting 1-2 millions of dollars per
year from 1 km of the coastal structures.
3.Protection of the coastline without capital hydraulic structures.
The wave energy station, situated along the coast line not so far from the bank, without any capital hydraulic structures with its own support allows reduction
the wave energy in 6-10 times and at the same time converting about 40 % of the initial wave energy into the useful work. The scheme allows to limit the
adverse impact of storms on the coastline, thereby minimizing the shore protection works that are expensive and not good from an environmental point
of view.
If compare the protection and repairing works on the beaches after storms and the placement of the wave energy damper you will see almost no difference.
But money, invested into it, are irrevocable; while the protective lines that consist of wave energy dampers make a profit by selling "clean" energy.
The cost value of electricity produced by the wave power station can be less than 0.01$.

Competitive advantages of the project

- Dual-use technology: protection from the wave impact and power generation;
- The energy damping device has an automatic management system and depending on the wave impact’s power and angle of approach of waves to the
shoreline , operatively changes physical parameters : displacement, mass; and also distributes the load on the generator that allows working on the waves of
different heights and frequencies of the period reliably and with high efficiency
- The working device has no hard connection with the ramp;
- Reduces the wave impact’s energy by 70-80%;
- Possibility of application in areas with the ice cover in winter
- Has the system of the radical reduction of the wave loads over the calculated that increases reliability of the system, allows emergency and maintenance
works in storm conditions because it has the system of the radical reduction of the wave loads above the estimated.
- The project meets the high environmental standards. All three technologies of the placement and mounting of the complex and the wave energy damper
are not capital building relative to the bottom of the coastal shelf. Protective dams formed by this technology provide flowage of the breaking water space,
pass season’s streams and do not cause silting of artificial newly created harbors, ensure migration of coastal bio resources.
-Do not have limitation on the storm’s power. (competitors goes into emergency mode.
- The combined energy conversion scheme with an independent energy balance;
-A building system with different mounting conditions;
- Allows to create protected energy-independent areas for recreational and economic activities.

Structural features of the wave damper and the control system alow to build a special algorithm of damping of the wave’s impact not only for each working
element of the station but across the width of the wavefront along the line of the Wave power station’s placement. That allows to exclude the deformation
of the wave beam when waves are aproaching the coastline; to avoid the concentration of the wave uplift on separate bank’s parts, coastal and protected
constructions; to prevent forming of explosive and alluvial streams and harbor oscillations in areas where Wave pover stations are situated.


Multifunctional marine complex

- Predesign works, calculation of the energy potential of renewable energy sources and the preliminary TEO are conducted
relatively to the real coastal areas under the contract with the company which is interested in a practical project realization.
- The conception and architectural and planning solution of all parts of the project are developed.
The coastal Hydro power station with protective functions of the shore is a key segment of the project it doesn’t only
protect it also allows to provide the energy and communications to the projected complex without using the engineering
networks situated on the shore.
