EMP Outline EnergySail Array for Naval & Coast Guard Ships

EMP say the technology can extended patrol ranges for the vessels

Japan's Eco Marine Power Co. Ltd. (EMP) today outlined details of the modified version of its Aquarius MRE System for use on naval and coast guard ships, saying its EnergySail technology will be used to form an array of devices able to harness renewable energy on the ships.

The technology can lower fuel consumption and emissions, as well as extended patrol ranges for vessels, it said.

"We view this latest development of our marine renewable energy technologies as a major step forward in terms of bringing safe, practical and cost effective wind & solar power systems to world shipping," commented EMP's Director of R&D Greg Atkinson.

EMP say the basic elements of the system remain identical, which simplifies parts management and maintenance when deployed across a fleet.

"A naval frigate could have up to four EnergySail's incorporated into its design whilst smaller patrol vessels and coastguard ships may be fitted with just two of the devices," it said.

EMP says each EnergySail is capable of performing as a rigid sail to provide propulsion, and could also be fitted with a range of solar and wind power technologies so that even with the ship at anchor, it would still be able to generate power through available wind and solar resources.

The Aquarius MRE System uses an integrated system of EnergySails, solar panels, and energy storage modules, and last month EMP said it plans to test a complete prototype within the year.

A control system which is currently being tested in co-operation with KEI System Ltd., will automatically raise, lower, and position each EnergySail to best suit the prevailing weather conditions.
