Submerged Tether-Moored Point Absorber |
|
This device concept was inspired by a device known as CETO5 (Carnegie Clean Energy, 2017), which is a bottom-referenced point absorber design. It consists of a cylindrical buoy which is submerged a couple of metres below the still water line. The device is tethered to a hydraulic pump-based power take-off mechanism which is located on the seabed.

This particular device was chosen as an illustrative concept, but Flexcom Wave is naturally capable of simulating other similar wave energy converters. Other similar devices include SeaBased and CETO6 (where the relative positions of the tether and power take-off mechanism are reversed).
If you have a specific device concept which is not currently accommodated by Flexcom Wave, you can always Migrate to Flexcom itself.

Power Rating |
The maximum power rating of this device. |
Power-Take Off: |
The power take-off component. You can select the relevant Power Take-Off from the list of components which you have already created in the Device Parts folder. |
(a)The electrical power matrix is capped at the maximum power rating of the device, which helps to limit the size and cost of the electrical generator.
(b)The Power Take-Off component is modelled using a combination of spring, damper and rigid elements. In the case of a Submerged Tether-Moored Point Absorber, the power take-off mechanism is inserted between the seabed and the lower end of the tether. You should ensure that the physical separation of these points in space (as governed by the Floater CoG below SWL, Tether Length and Seabed X inputs) is consistent with the Geometry of the power take-off mechanism. Specifically, the separation must not be less than the Contracted Length and not greater than the Extended Length (which is equal to the sum of the Contracted Length and the Maximum Stroke-Out).

Floater: |
You can select the relevant Floater from the list of components which you have already created in the Device Parts folder. |
Floater CoG below SWL: |
The vertical distance between the Centre of Gravity of the floater and the still water line. A positive value indicates submergence. |

Tether: |
The supporting tether which connects the floating body to the power take-off component. |
