Design tradeoffs of an oil-hydraulic power take-off for wave energy converters
Renewable Energy, 2018Abstract This paper presents the main design tradeoffs that should be handled when developing oil-hydraulic Power Take-Off devices aiming at the maximization of energy extraction from waves with a point absorber wave energy converter. These tradeoffs were identified in a case study of a new Power Take-Off concept.

Power take-off concept for wave energy converters based on oil-hydraulic transformer units
Renewable Energy, 2016A generic oil-hydraulic based power take-off concept applicable to different Wave Energy Converters is presented. This power take-off is developed to have well-adapted characteristics to larger power and low frequency waves and to minimize spring, oscillatory and transient effects of the oil caused by the operation of valves which lead to the damage of

Bond graph modelling of a wave energy conversion system with hydraulic power take-off
Renewable Energy, 2012A system viewpoint is essential in the study of wave energy converters, since several different energy domains are involved in such devices. In this regard, bond graph, a graphical, port-based approach to modelling engineering systems, serves as a useful tool.

Low-Pressure Circuit Design for Hydraulic Power Take-Offs in Wave-Powered Reverse Osmosis
Approaches to powering reverse osmosis (RO) desalination using wave energy include 1) a direct conversion to hydraulic power in the form of pressurized seawater (feed water) and 2) generation of electrical power using wave energy and using the electrical power to drive a conventional RO system.Simmons, Jeremy, Van de Ven, James

Model Experiment on an OWC-Type Wave-Energy Converter With Hydraulic Power Take-Off
21st International Conference on Offshore Mechanics and Arctic Engineering, Volume 4, 2002A wave-energy converter of the OWC type is described, in which the absorbed wave energy is converted to useful energy by means of a hydraulic power take-off. Means are provided to enable the float to be latched for phase control. The float is connected to a piston pump, which pumps water from the level of the water in the wave channel to a higher level,

Comparison of Hydraulic Power Take-Offs With and Without Continuous Control Force Capabilities
Energy in ocean waves can provide us with clean, predictable energy when and where we need it most. The levelized cost of the energy (LCOE) produced by wave energy converters is still too high for widespread deployment of wave energy despite other advantages. Wave energy must be made more economical by increasing the electrical output while keeping theWills, Jackson, Li, Perry
