Control of wave energy converters (WECs) has been very often limited to hydrodynamic
control to absorb the maximum energy possible from ocean waves. This generally ignores or …

Ocean wave energy is one of the most abundant energy sources in the world. There is a
wide variety of wave energy conversion systems that have been designed and developed …

The Wavestar Wave Energy Converter (WEC) is a multiple absorber concept, consisting of
20 hemisphere shaped floats attached to a single platform. The heart of the Wavestar WEC …

A 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 …

Wave Star has produced and installed a test and demonstration Wave Energy Converter
(WEC) by Roshage pier near Hanstholm at the west coast of Denmark. The test unit is a …

The world's oceans, covering approximately 71% of the Earth's surface, harbor vast wave
energy resources, offering a potential solution to the pressing energy crisis and …

This paper analyses the current state of the art in linear actuation with digital hydraulics.
Based on the differences in their aims the paper partitions the area into four actuation …

In this paper, a special type of multi-chamber cylinders along with secondary controlled
hydraulic motors are key components in the design of a highly efficient hydraulic series …

The variable displacement oil-hydraulic pumps for the Power Take-Off (PTO) of wave energy
converters must work above 80% of maximum displacement in order to have an overall …

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 …
