Rotor Sail Technology

Dealfeng Rotor Sail a modern fully-automatic mechanical Flettner Sail. The product, driven by electrical motor to rotate the cylinder onboard, utilizes the Magnus effect to harness the power of wind to create auxiliary propulsion thrust for propelling the ship forward. It allows the ship lowering main engine power, resulting in fuel saving and GHG emissions reduction.

Rotor Sail System

Dealfeng Rotor Sail is a reliable and easy-to-operate wind-assisted propulsion system that is composed of four parts including Rotor Sail body, foundation & inner tower, multifunctional sensors and central control system. The Rotor Sail is available in different models and foundation types (fixed, tilting and rail), the body is made from lightweight composite material and the inner support is high-tensile steel structure. The optimal size and number of Dealfeng Rotor Sails installed on a ship is determined by the parameters and dimensions of the ship.

Rotor Sail Installation

Dealfeng conduct a case-by-case feasibility study to work out the optimal arrangement scheme by utilizing our technical expertise in shipbuilding and marine industry in combination with the familiar to the fleet, such as general arrangement, sailing schedule and time, navigation route and other necessary information, ensure the installation scheme in accordance with customers' requirements and maximize the reduction of fuel consumption and carbon emission along the route.

Rotor Sail Efficiency

Marine industry is currently facing significant challenges from increasingly stringent environmental regulations. Rotor Sail is a cost-effective, proven technology that can help comply with the targets and regulations of the IMO and the EU for reducing GHG emissions from shipping, also is a more mature technology that currently the most installed on ships when compared to some other wind propulsion technologies and a possible solution to help improve the ship’s energy efficiency and reduce operational carbon intensity.
