Sail EnergySail runs on the energy of wind and sun
The conceptual system developed by the Japanese company Eco Marine Power, based on the use of rigid sails, combined with solar panels.
Installed on individual hard mast sail EnergySail automatically "catches the wind", turning in the right direction to provide the ship motion. At the same time set the sail solar cells electricity Board to the consumers, which reduces the load and fuel consumption of electric generators. During a storm or when a vessel in port, the sails can be folded.
Electricity produced by the solar panels can be stored in batteries and used for Parking. In addition, the panels can operate during Parking. A modified version of the EnergySail allow their use even in a horizontal position.
According to the company, hard sails are designed with minimal maintenance and operation in difficult weather conditions. They will be able to withstand strong wind and high humidity.
Based on its previous concept of the Aquarius Eco Ship – project cargo vessel with an array of 14 hard sails, Eco Marine Power has recently introduced a modification of the system, intended for installation on smaller vessels, such as military frigates or coast guard ships.
The project for the naval frigate involves the installation of four sails, patrol boats and patrol vessels to be equipped with two. Individual ships can be equipped with one sail EnergySails. According to reports, the company is working to develop projects in very small vessels such as fishing boats.
Eco Marine calculations show that annual savings of hydrocarbon fuels during their use of the invention can be up to 20%. Specific savings depend on the type of fuel and method of its use. For example, the electric vessels, ships equipped with electric engines, fuel consumption can be reduced by 40%. Given the huge figures of fuel consumption in Maritime vessels, such savings could lead to a significant reduction of emissions of greenhouse gases in the atmosphere.
In addition, the company's claim that EnergySails provide accurate control at low speeds, which is important in ports and bays.
Currently, Eco Marine Power is testing the control system of sails, which will have the function of automatic alignment, ascent and descent EnergySail. The company hopes to be able to start sea trials in 2013.
