Eco Marine Power (EMP) of Japan has commenced a feasibility study regarding the installation of its Aquarius Marine Renewable Energy (Aquarius MRE) solution onto a LR2 Tanker.

The study is being undertaken in co-operation with the ship owner, which has not yet been named. It is described as a major step towards commercialisation of the system, and will investigate the influence of the various technologies on fuel consumption and emissions. Also involved in the study are Teramoto Iron Works, Furukawa Battery Company, KEI System, and Fuji Trading.

The scope of the feasibility study includes:


  • investigating installation locations for marine-grade solar panel and frames,
  • an energy-storage system,
  • an automated alarm and monitoring system, and
  • the fitting of EnergySails to the ship.


The LR2 Tanker selected for the study is about 240m in length and is the largest ship of this type investigated in detail by EMP for the installation of a complete Aquarius MRE system. Aquarius MRE is a zero emissions power and propulsion system that incorporates an array of automated rigid sails, marine-grade solar panels, energy storage modules, charging equipment and computer systems. Aquarius MRE enables ships to tap into renewable energy by harnessing the power provided by the wind and sun. The array of rigid sails are automatically positioned by a computer system to best suit the prevailing weather conditions and can be lowered and stored when not in use or in bad weather.

The rigid sails are based on EMP's patented EnergySail technology and these renewable energy devices can be used when a ship is at anchor or in harbour. Each EnergySail can be configured with a mix of sensors, photovoltaic panels or other power generating devices.

The study will include modelling of the expected fuel consumption and emission reductions that could be achieved via the use of Aquarius MRE, plus CFD modelling of airflow around the ship. EMP is investigating the most suitable marine-grade solar panels for the project and the feasibility of adding further equipment including low power LED lighting and other power saving devices.

Preparation for the feasibility study commenced in 2019 when a vessel survey was conducted and it is expected that the feasibility study phase will be completed in early 2021. Some equipment for an initial system trial may be installed on the ship within 2020.
