Eco Marine Power (EMP) has confirmed that, in cooperation with various technology partners and shipping companies, it has begun a detailed study focused on the practical applications of its patented EnergySail and Aquarius MRE technologies.

The study is to cover the engineering aspects of installing an EnergySail- or Aquarius MRE-based solution on a variety of ships and the expected fuel oil consumption (FOC) and CO2 savings that can be achieved in an operational environment. Energy storage options are to also be studied - including the possible use of fuel cells.

Technology partners currently involved in the study with EMP include Japanese firms Teramoto Iron Works Co., Ltd., KEI System Co., Ltd. and The Furukawa Battery Co., Ltd. The names of the shipping companies involved in the study were not named "for confidentiality reasons".

More than a dozen ships are to be included in the study - ranging in size from coastal chemical tankers to large ro-ro ships, bulk cargo carriers and LNG tankers.

For each ship involved in the study, a preliminary engineering design will be prepared along with an analysis of the ships operational profile. The engineering phase will include ship surveys, on-board data collection, analysis using computational fluid dynamics (CFD) software and virtual wind tunnel simulations. Computer modelling of ships fitted with EMP's EnergySail and Aquarius MRE technologies will be also be performed.

Additional tests and simulations are to be carried out using a prototype version of the EnergySail connected to a computer system and sensors in a test lab in Osaka. The aim of the tests and simulations will be to assist in fine-tuning FOC and CO2 emission savings models.

EMP's EnergySail is a rigid sail based device that can be fitted with a range of renewable energy technologies such as solar panels or wind power devices. Aquarius MRE is an integrated renewable energy system for ships that incorporates EnergySail technology along with other elements such as marine solar power, energy storage and a computer system to monitor ship performance.

Last year, the first factory-produced version of an EnergySail was manufactured by Teramoto Iron Works, and an EnergySail Test Station has also now been established.

Commenting on this latest development, Greg Atkinson, Chief Technology Officer at Eco Marine Power, remarked: "It's very encouraging that we now have a number of ship owners actively looking at how our technologies can be fitted either to ships in their existing fleet or incorporated into new ship building projects."

EMP says it is also working with partners on a project to produce class-approved EnergySail units for possible inclusion into a new ship building project in 2017.
