SkySails propulsion is currently at pre-series stage. There are less than 10 ships fitted with this propulsion sys-tem worldwide.
The components of the SkySails-System can be divided into two categories: on-board components (launch & recovery system, steering system) which are installed on the ship and the so-called „airborne system“ (Towing kite, control pod, towing rope) which performs controlled, dynamic flight maneuvers in the air in front of the ship and thus generates propulsion power.
In routine operations the towing rope of the 160m2 towing kite of the SKS C 160 is let out to a length of approx. 280 meters. The towing kite is performing its standard flight maneuvers in the form of a “horizontal figure-eight” at an altitude of 150 to 200 meters off the vessel’s leeward side.
A flight pattern such as this normally covers a width of 250 meters and a height of 50 meters.
SkySails-Systems operate outside the 12-mile limit, i.e. beyond the limits of national jurisdiction under the Uni-ted Nations Convention on the Law of the Sea (UNCLOS). It is here that the SkySails operate in Class G air-space below 2500 feet (800 m). This is recognized as uncontrolled airspace where visual flight rules (VFR) apply. The SkySails-System is easily recognizable during daylight because of its size and has lighting when flown at night. The system operates within the ship’s safety zone, which low-flying aircraft – including military aircraft – must avoid pursuant to regulations.
As a preventive measure, information is provided to the aviation authorities of the states being passed to ensure that all pilots are informed using what is called NOTAM (Notice to Airmen). SkySails will continue to recommend to its customers that they adhere to this internationally recognized and proven practice.
Furthermore, SkySails actively conducts consultations with national and international agencies and associations in order to achieve a set of binding and internationally coordinated rules. SkySails will report regularly on this matter
