Preferably, the container is filled with gas to react against the expandable bladder. The bladders receive the hydraulic fluid from the cylinders 400 and expand and contract in response to the pulsed energy input against the pressure of the gas within the container. The secondary chamber 16 is located substantially centrally towards the upper end 22 within the spar buoy 12. The pressure control valve 18 can be selectively opened to enable fluid communication in the direction from the primary chamber 14 to the secondary chamber 16. A check valve may be incorporated to prevent flow in the reverse direction. The pressure in the primary chamber 14 will fluctuate according to the input of pressurised fluid from the air compressors 40 delivered by air supply lines 34. The pressure of the primary chamber 14 is maintained at a higher level than that of the secondary chamber 16. The primary chamber 14 is provided with a bilge (not shown) such that moisture contained in the air will gather in the primary chamber 14 and collect in the bilge as water and this feature has the advantage that only relatively dry air will proceed to the secondary chamber 16. The moisture/water is then removed by a bilge pump (not shown).

Preferably, the pressure of the first chamber is maintained at a higher level than that of the second chamber. The method can include housing the chamber in a body and shaping the body such that it is substantially stable in response to the motion of the waves. The interior of the spar buoy 12 contains a primary chamber 14, valve means in the form of a pressure control valve 18 and a secondary chamber 16. Air supply lines 34 enable fluid communication between the inner end 49 of air chambers 48 and the primary chamber 14. The air supply lines 34 are provided with one way check valves (not shown) to permit flow of air from the air chambers 48 to the primary chamber 14 but prevent flow in the reverse direction and thus prevent backflow of pressurised air.
Also attached to each lever arm 42, 43 and a point on the spar buoy 12 is an air compressor 40. The air compressor 40 comprises a rod 46, a piston (not shown) and an air chamber 48. The piston is located at one end of the rod 46 and is movable axially within the air chamber 48. Leakage of air from the air chamber 48 is prevented by O-ring seals to provide a seal between the outer diameter of the piston and the interior of the air chamber 48. A distal end 47 of each rod 46 is fixed to the corresponding lever arm 42, 43 and one end 49 of each air chamber 48 is attached to the spar buoy 12. Thus lever arms 42, 43, air compressors 40 and a portion of the spar buoy 12 occupy a triangular configuration.
Depending on the pressure within each chamber 14, 16, the pressure control valve 18 selectively allows air to flow from the primary chamber 14 to the secondary chamber 16. The pressure sensing means and pressure control valve 18 allow the interior of the secondary chamber 16 to be accurately pressure controlled. Compressed air from the air compressors 40 is fed by the air supply lines 34 into the primary chamber 14 of the spar buoy 12 to increase the pressure therein. Causas de dolor de hombro derecho . Below the minimum wave height the control system can close the valve means 18, turbine 28, motor 128 and generator 30, 130 with the floats 44, 45 and fluid compressors 40, 400 slowly allowing pressurised fluid to accumulate in the primary chamber 14 or bladder. Movement of the floats 44, 45 compresses hydraulic fluid within the cylinders 400. The pressurised fluid is delivered from the lines 134 to a series of chambers in the form of accumulators 114. Although three accumulators 114 are shown in series in FIG.
This can be achieved by the container and bladder arrangement or the combination of two chambers allowing a constant, more reliable source of pressurised fluid to enter the conversion means. In the storm survival mode the control system can lock the energy transfer mechanism in a pre-determined position and the at least one member can be retracted to avoid damage thereto. Two substantially opposing sides of the body can each be provided with two members coupled thereto.
The or each member can be coupled to an end of an arm and another end of the arm can be pivotally coupled to the body. According to another preferred embodiment shown in FIG. The method can include pivotally coupling one end of an energy transfer mechanism to the arm and another end of the energy transfer mechanism to the body, vertically spaced from the coupling with the body and the arm. The pivotal attachments 82 u, 82 l enable the spar buoy 12 to pivot around the anchor arm 80 and enable the apparatus 100 to be correctly oriented relative the wavefront.

The apparatus 100 is also provided with an anchor arm 80 having an eyelet 81 for attaching an anchor (not shown) thereto. However, the air cylinders 40 have been replaced with cylinders 400 for receiving and compressing a hydraulic fluid as the floats 44, 45 move between wave crests 54 and troughs 56. A hydraulic fluid reservoir 171 is provided within the spar buoy 12 for supplying hydraulic fluid to the cylinders 400 via hydraulic fluid supply lines 134. The lines 134 have check valves 135 fitted thereto to permit flow of the hydraulic fluid in one direction only.
