Objectives The objective of this project is to deliver an optimised, reliable, highly efficient hydraulic motor through the use of Digital DisplacementTM technology, to drive electrical generators at the downstream end of the power take-off system in a marine renewable-energy device.
Abstract Artemis Intelligent Power was spun out from the University of Edinburgh after the first Digital DisplacementTM pumps/ motors had been built. These were designed to be highly controllable hydraulic machines, which maintain a high efficiency over the whole displacement range. The Digital DisplacementTM technology is able to improve significantly the overall performance of a marine renewable-energy device. This project will look at integrating the Digital DisplacementTM technology into project partner Ocean Power Delivery s wave energy device, Pelamis, to confirm its efficiency, controllability and reliability. The project will be divided into the following phases: specification and outline design study of the Digital DisplacementTM motor to understand fully the demand for hydraulic transmissions in the marine renewable-energy market; detailed 3D design of all motor components with all hardware, electronic control system and electronic components specified; manufacturing planningand component ordering; assembly and commissioning of the different components of the Digital DisplacementTM motor; testing the Digital DisplacementTM motor on the existing full-scale power module test rig of Ocean Power Delivery Ltd to analyse fully Digital DisplacementTM performance against current hydraulic motors. Results from the test work will be recorded and analysed to confirm efficiency, controllability and reliability. These will then be used in discussions with potential manufacturers and clients
