Japan-based Eco Marine Power Co. Ltd. (EMP) unveiled a concept ship design incorporating its Aquarius Marine Renewable Energy (MRE) System. This concept design is called the Aquarius Eco Ship and is part of Eco Marine Power’s ongoing development efforts aimed at moving shipping towards a more sustainable future.
The Aquarius Eco Ship is the result of a comprehensive study project which focused on optimizing the design of a large ocean going ship such as a bulk carrier or oil tanker to harness the power of the wind & sun by using the Aquarius MRE System.
The Aquarius MRE System incorporates a variety of elements including solar panels, energy storage modules, a computer control system and an advanced rigid sail design.
This green shipping focused solution has been designed to be highly flexible and configurable so that it can installed on variety of ship sizes and types. Applications for the system include bulk carriers, oil tankers, survey ships, passenger ferries and even unmanned surface vessels.
In addition to the Aquarius MRE System, a future Aquarius Eco Ship would also be fitted with other fuel saving measures such as an advanced electrical propulsion system, an optimized hull design and waste heat recovery technologies.
This combination of technologies could lead to fuel savings of 40% or more and also reduce the emission of sulphur oxides and nitrogen oxides.
An Aquarius Eco Ship could include enough solar panels for 1MW solar system or larger and enough energy storage modules so that the ship would not need to use auxiliary diesel generators while in port. These energy storage modules could be charged via the solar panels or by the ship’s main generators.
The Aquarius Eco Ship and Aquarius MRE System have been designed to take into account the reality of operating rigid sails on ocean going ships and include a range specially developed safety features.
Eco Marine Power is now seeking to work with a shipyard or shipping company in order to further develop the Aquarius Eco Ship concept. It is anticipated that this work will lead to the development of several new design concepts and possibly additional patent applications.
The company will also begin test activities related to the Aquarius MRE System this year and is seeking to co-operate with additional development partners and strategic investors in order to produce a commercial version of the system.
