Abstract

A deployment device and system for a hydrokinetic energy converter such as a hydrokinetic turbine that can be coupled to a generator to produce electricity. The deployment device can include a floatable platform including a central aperture sized to allow a hydrokinetic turbine to be lowered therethrough into water. A pair of deployment swing members are rotatably attached to the platform and located adjacent to the central aperture. Each deployment swing member has a support for connection to an end of a hydrokinetic turbine. Each deployment swing member is rotatably supported for rotating the swing members from a first position in which the swing member and any attached turbine are raised at least partially out of the water, through the central aperture, and to a second position in which the swing member and any attached turbine are lowered beneath the platform at least partially in the water.

wherein each deployment swing member is rotatably supported for rotating the swing members from a first position in which the swing member and any attached turbine are raised at least partially out of the water, through the central aperture, and to a second position in which the swing member and any attached turbine are lowered beneath the platform at least partially in the water, and

wherein each deployment swing member comprises two arms, and wherein the support for connection to the hydrokinetic turbine is connected between the two arms.

2. The deployment device according to claim 1, wherein the floatable platform includes an inflatable buoyancy structure.

3. The deployment device according to claim 1, wherein the floatable platform includes a removable buoyancy structure.

4. The deployment device according to claim 1, wherein the floatable platform is attachable to or provided as part of a boat.

5. The deployment device according to claim 1, wherein each deployment swing member is rotatable independent of the other deployment swing member.

6. The deployment device according to claim 1, further comprising processing means and at least one motor or hydraulic to rotate the deployment swing members, wherein the processing means include at least one program for moving first one deployment swing member from the first position, through the central aperture to the second position, and then the other deployment swing member fully from the first position, through the central aperture to the second position.

7. The deployment device according to claim 1, wherein the support for connection to the hydrokinetic turbine comprises a first beam connected to one of said arms, and a second beam connected to the other of said arms, such that a gap is provided between the first and second beams, wherein a nose cone of a hydrokinetic turbine is positionable at least partially in the gap between the first and second beams, and wherein at least a portion of the nose cone is attachable to the first beam and at least a portion of the nose cone is attachable to the second beam.

8. The deployment device according to claim 1, wherein at least one of the arms of at least one of the deployment swing members includes a conduit for receiving a pipe or cable capable of connecting the hydrokinetic turbine to a hydrokinetic generator.

9. The deployment device according to claim 1, further comprising a hydrokinetic generator provided on the floatable platform and connectable to the hydrokinetic turbine.

10. The deployment device according to claim 1, wherein the deployment swing members are rigid.

11. The deployment device according to claim 1, further including support brackets attached to the floatable platform for rotatably supporting the deployment swing arms.

12. The deployment device according to claim 11, wherein the support brackets include stops to prevent outward rotation of the deployment swing arms beyond the first and second positions.

13. The deployment device according to claim 11, wherein the support brackets support axles therebetween for rotatably supporting the deployment swing arms.

14. A method of deploying a hydrokinetic energy converter comprising the steps of:
