6. Super Watt Wave Catcher Barges© Allow Many Types Of PTOs To Be Used Inside A Safe Helicopter Accessible Above Water Enclosed Work Environments

PTO Option 1- Radial Hydraulic Pumps:  One or more radial hydraulic pumps can be mounted to the barge in some way and turned by the drive belts. This illustration shows how two radial hydraulic pumps can be mounted to the barge and share the use of a common unidirectional drive pulley. Different size radial pumps are available which can meet most wave energy converter needs. Larger pumps can be en

Radial Hydraulic Pumps deliver high pressure hydraulic fluid to accumulators which is used to drive hydraulic motors which turn electric generators. These hydraulic pumps can be left in the open on the barge deck or inside an enclosure. Pumps up to 1 megawatt in power are currently available and larger pumps can be engineered.

PTO Option 2 -Long stroke hydraulic jacks: can be used to deliver high pressure hydraulic fluid to banks of hydraulic accumulators and to adjust line lengths for wide ranges in tidal variations. The size of hydraulic jacks can be increased to match the power production potential of these barges.

PTO Option 3 - Linear Generators: 

• can be oriented in the vertical or horizontal in a similar manner to the hydraulic jacks. 
• can generate power directly but the power needs to be converted be used by the grid. 
• power conversion can be done on the barges, on a local offshore power hub or somewhere onshore. 
• sizes can be increased to match the maximum power production capabilities of the barges.
