The worldwide patented SkySails Power system consists of five main components: a free flying kite with rope, a launch and recovery system, an automated control system, a generator for producing electrical power and a support platform.

During launch the towing kite, which is folded like an accordion, lifts itself out of its stowage. It is then lifted to take-off height at the launch and recovery mast. At sufficient height the towing kite unfurls to its full size and is launched. A winch releases the towing rope until operating altitude is reached. The SkySails Power system is operated at altitudes of between 200 and 800 meters.

Energy is generated as the wind pulls the rope from a winch drum that is connected to an electric power generator. This is the power phase in which electrical power is produced. The return phase begins once the rope has been extended to its maximum length. The kite is then automatically flown into a position where its pulling force is very low. This is when the generator acts as a motor and reels in the rope until its extended length is short enough for the next energy-generation phase to begin. This process consumes only a fraction of the power generated during the power phase. The residual excess energy is fed into the electrical power grid.

The recovery process is performed in reverse order: the winch retracts the towing rope and the towing kite is docked to the launch and recovery mast. Then the towing kite is reefed and lowered into the stowage..

The SkySails Power system can be utilized onshore as mobile or fixed units as well as offshore, installed on both conventional offshore foundations and on floating platforms. That way the SkySails Power system can also be secured quickly and easily at water depths of down to 700 meters using traditional anchoring technologies and readily available offshore support vessels.

SkySails Power technology is based on the acclaimed and worldwide patented SkySails propulsion system for ships. This system has been proven and tested in the tough day-to-day use on board seagoing vessels. In good wind conditions, it can replace up to 2 megawatts of power from the main engine with the use of fully automated towing kites of 400 m2 in size.
