Another major drawback of such prior art systems is the need to be close to shore where the energy loss for 5 shoreline waves is high due to frictional losses, thus missing out on the majority of the wave energy present in ‘deep’ water. As the chamber 112 is open to the ambient ocean its buoyancy will vary with hydrostatic pressure variations due to wave motion. The counterbalancing means 53 comprises a mass having an adjustable buoyancy tank provided in connection therewith, as illustrated in 5 Figure 9. The counterbalancing means 53 of this embodiment is in the form of a hollow vessel 55 having a solid base 56 of a predetermined mass to act as a counterweight for the submerged member 46. The remaining volume of the vessel 55 can be filled with compressed air via an air hose 57 to adjust the 10 buoyancy of the vessel 55. A valve 58 may be provided in a wall of the vessel 55 to expel air to the ambient ocean.

Extraction of the vertical energy in a wave may be implemented in a Wave Energy Converter (WEC) using a single heaving body or two heaving bodies. With the frequency tuning ability of the apparatus 10, it is possible to extract energy from the predefined frequencies only, while simply letting the destructive high energy density waves pass without attenuation. The tension mooring system 120 still operates as an oscillating system which can be tuned to the frequency of the waves in the ocean to extract maximum energy 30 from the heave response of the canister 122. Now that several embodiments of the wave energy converting apparatus and tension mooring system have been described in detail, it will be apparent that – 23 the described embodiments of the apparatus provide a number of advantages compared with the prior art, including the following: (i) The wave energy converter is robust in design, being able to withstand most weather conditions with minimal likelihood of 5 damage.
In storm conditions the wave energy can be massive, causing the destruction of many of the prior art land- or shore-based systems. The tension mooring system enables the wave energy converting apparatus to be tuned to the prevailing ocean conditions to maintain maximum efficiency. The opposing motion of the two bodies ensures the maximum amount of differential motion and hence the maximum amount of energy extracted from the wave.
A single heaving body uses a buoyant mass on top of the surface of the water 5 to extract the vertical energy of a wave. The preferred embodiments of the WEC of the present invention typically employ a surging and heaving body design, which uses multiple degrees of 15 freedom to extract energy from the travelling waves of the ocean. Dolor de espalda baja y caderas . A -7 surging body is capable of extracting half of the wave energy, namely the horizontal energy component of a wave. Such a novel use of heave increases the survivability of the WEC without sacrificing the efficiency of the energy extraction. The downward force applied to the PBSM 14 will be opposed by the damping provided by the linear electric generator 20. The result of the upward force applied to the float member 18 via its hydroplanes 30 and buoyancy is an upward movement of the translator 24 of the linear electric generator 20. Through the interaction of these buoyant and hydrodynamic 10 forces it is possible to maximise the differential motion between the float member 18 and the support structure 12 in order to optimise the energy extracted from the wave by the apparatus 10. To counteract the upward buoyant force on the PBSM 14 a novel tension mooring system has been invented, of which a preferred embodiment, in the 15 form of mooring means 60, is illustrated in Figures 4 and 5. The mooring system 60 comprises a ballast 62 for anchoring the device, and a counterbalancing means 64 for counteracting the excessive buoyancy of the PBSM 14. The ballast 62 and the counterbalancing means 64 are connected via a chain or cable 66, which passes through a pulley mechanism 68 located 20 at the bottom of the PBSM 14 (see Figure 5). A dampening means in the form of a mechanical braking system 70 is provided in connection with the pulley mechanism 68, though some other dampening means such as an electrical or hydraulic or pneumatic dampener can be used.

Preferably the buoyancy of the counterbalancing means can be 5 adjusted by pumping air into the buoyancy vessel via an air hose. Electrical power generated by the linear electric generator 20 is tapped off via an electrical power terminal 15 26 provided at the top end of the stator 22, and may be carried to shore via a suitable underwater cable (not shown) or by wireless (microwave) transmission. In the present invention heave response may also be used to ‘tune’ the operational 25 frequencies, such that frequencies below its tuned frequency will experience minimal attenuation. As the motion of the stator 22 and the translator 24 are subjective, the locations of the copper wire, magnets, and magnetic permeable material can also be 15 located on either the stator or the translator.

It will therefore be referred to in this embodiment as a positively buoyant submerged member (PBSM) 14. The buoyancy of the PBSM 14 extends 30 beyond the mean water level such that if the water level were to rise the associated buoyancy force would also increase. Once the switch is opened the shunt to the solenoid will be opened, thus allowing the PBSM 25 14 to rise in altitude and relieve the upward stress provided by the float member 18. This altitude adjustment will continue until such time as equilibrium is achieved. The mooring means 60 is designed to be a fully automatic adjustment system, which will keep the mean water level of the apparatus 10 at a 30 consistent level. The second configuration uses a structure fixed to the ocean floor, this structure is located either below or above the mean water level and will have a buoy attached to it; this buoy will then oscillate with the waves on the surface of the water producing differential motion against the fixed reference frame.
