Onomichi MTTC

Test and Evaluation Center for Shipping, Marine and Offshore TechnologiesEnergySail Demonstration Unit at Onomichi MMTC

The Onomichi Marine Tech Test Center or Onomichi MTTC is located at the Teramoto Iron Works Chojahara Workshop in Hiroshima Prefecture, Japan. Onomichi is a major center of ship building and ship repair industries.

The centre includes a large outdoor evaluation area which is used to develop, test, evaluate and demonstrate new technologies or provide support for products in service. Equipment installed at the center includes a jack-up rig for offshore wind power facilities, marine solar power panels, marine-grade frames for ship photovoltaic (PV) systems and an EnergySail test unit.

A key focus at the Onomichi MTTC is renewable energy related technologies for shipping, marine and offshore applications. The aim is to help develop solutions that will assist with the transition of shipping to a zero emissions future.

The Onomichi MTTC is also being used as a test and R&D centre for Eco Mainre Power's patented EnergySail and Aquarius MRE technologies.

JAMDA Rigid Sail at Teramoto Iron Works in the 1980'sTeramoto Iron Works (established in 1934) has a long history of product innovation and was involved in the production of rigid sails for ships in Japan around four decades ago.

These rigid sails were known as "JAMDA"  (Japan Marine Machinery Development Association) sails and the fuel savings on ships that used them ranged between approximately 10% - 30%. Trials using these sails also showed that they were capable of moving the ship at low speed without the use of the main engines.

Variations of these rigid sails could be folded when not in use and they proved the viability of using rigid sails as a means of auxillary propulsio to reduce fuel consumption on powered vessels.

The JAMDA rigid sail experience makes the Onomichi MTTC the ideal location for the ongoing development of the EnergySail and other renewable energy solutions for shipping including marine solar power. In addition other solutions for shipping, marine and offshore applications are also developed and tested at the center.

Unmanned Surface Vessel (USV) Powered by Renewable Energy (Under Development)

The Aquarius USV™ is being developed as a cost-effective Unmanned Surface Vessel (USV) or Autonomous Surface Vehicle (ASV) that will incorporate a number of technologies from Eco Marine Power & its strategic partners. These technologies include the patented Aquarius MRE and  EnergySail plus high performance marine batteries & lightweight flexible marine solar panels.

Aquarius USV by Eco Marine PowerThe Aquarius USV will be powered by a solar-electric hybrid marine power (HMP) solution which will also feature a solar panel array designed by EMP. On-board batteries will be re-charged via the solar-panel array or via ship or shore power using rapid battery re-charging technology.

The vessel will be fitted with compact low power marine computer systems which will utilise the KEI 3240 platform - this flexible marine computer system architecture has proven itself to be reliable on hundreds of vessels ranging from tugboats to ocean going bulk ore carriers and tankers.

The vessel will also be fitted with a sensor pack including several unique sensors developed by EMP. These sensors will be able to collect data from above and below the waterline and this data can either be stored on-board the vessel and/or transmitted back to a ship or shore office. Data transmission will be possible via Wi-Fi, mobile phone or satellite connections.

The Aquarius USV's shallow draft and low height will allow it to operate on urban waterways, rivers, bays and lakes in addition to being suitable for coastal waters and missions at sea. If needed, the masts can also be lowered (optional) to give the vessel a stealth capability.

Typical missions for the Aquarius USV could include monitoring harbour pollution, oceanographic surveys, maritime park surveillance, port security, coastal border patrols, marine data collection and anti-submarine warfare (ASW).

A variation of the Aquarius USV will include a stand-alone version of EMP's unique EnergySail technology in order to extend the vessel's range and allow for additional sensors to be fitted.

EMP is also studying the possibility of developing a robotic version of the Aquarius USV.

Zero Emission Ship Design Concept with Rigid Sails & Solar Power

Pathway to Zero Emission Shipping

The Aquarius Eco Ship is a green shipping concept design and ongoing comprehensive study project focused on optimizing the design of ocean-going ships such as a bulk carriers, tankers, RoRo vessels and cruise ships, to harness the power of the wind & sun plus incorporate other emissions reduction and energy efficient technologies and future propulsion systems including hydrogen fuel cells.

The Aquarius Eco Ship study project was started by Eco Marine Power Co. Ltd (EMP) in May 2011 and has attracted world-wide interest. So far it has led to the development of several patented design concepts and the trial and commercialization of a ship-based solar power system: Aquarius Marine Solar Power.

Sail Assisted Shipping with Solar Power 

The centre piece of the Aquarius Eco Ship is Aquarius MRE (Marine Renewable Energy) - an innovative and patented fuel saving and emission reduction system that incorporates a variety of elements including marine-grade solar panels, energy storage modules, computer control systems and an advanced rigid sail design.

Aquarius Eco Ship by Eco Marine Power

Aquarius MRE is a zero emission & wind assisted (or sail assisted propulsion) solution which has been designed to be highly flexible and configurable so that the concept can be applied to most ship sizes and types.

Applications for the system include bulkers, oil tankers, general cargo ships, survey ships, passenger ferries, cruise ships, Ro-Ro ships, car carriers & even unmanned surface vessels.

In addition to Aquarius MRE, a future Aquarius Eco Ship would be fitted with other fuel saving measures such as an advanced electrical propulsion system, low power LED lighting, air lubrication, an optimised hull design and waste heat recovery technologies. Fuel cell technology could also be incorporated into the design.

This combination of technologies could lead to fuel savings of 40% or more when applied to existing ship designs and also dramatically reduce the emission of noxious gases such as Sulphur Oxides (SOx), Nitrogen Oxides (NOx) and particulate matter (PM). In addition the use of renewable energy and energy saving measures would reduce the vessels carbon (CO2) footprint.

An Aquarius Eco Ship could include up to 1 MWp of solar power and enough energy storage modules so that the ship would not need to use auxiliary diesel generators whilst in port. This could also enable the ship to operate emissions free when Aquarius Eco Ship CFD Analysisalongside or an anchor.

Both the Aquarius Eco Ship and Aquarius MRE have been designed to take into account the reality of operating rigid sails on ocean going ships and include a range of software and hardware related safety features. The rigid sails for example, can be lowered and stored when not in use or during extreme weather or emergencies. The automated control system will also lower or position the rigid sails to avoid injury to the crew or damage to the ship or sails.

EnergySail Technology - Wind Power & Solar Power for Ships

The rigid sails used by the Aquarius Eco Ship form part of Eco Marine Power's patented EnergySail technology. This renewable energy sail platform allows for a variety of energy sources to be used and managed via the same system. Solar panels & wind power devices can be mounted on the rigid sails or elsewhere on the ship in a variety of configurations.

Aquarius MRE technology will enable ships of all types and sizes to safely use renewable energy in order to reduce fuel consumption and lower harmful emissions in a cost effective way. The Aquarius Eco Ship is an example of how this system could be integrated into a new ship design although it is also suitable for existing ship designs and could be retro-fitted to vessels already in service.
