SkySails

SkySails is a trademarked name referring to a type of auxiliary propulsion system for ships. The system utilizes a large, computer-controlled kite to harness wind energy and reduce the load on the ship's main engines. This, in turn, lowers fuel consumption and emissions.

The SkySails system typically consists of a large kite (often referred to as a traction kite), a towing rope connecting the kite to the ship, and an automated launch and recovery system integrated into the ship's structure. The kite is deployed to altitudes where stronger and more consistent winds are available. Sophisticated control algorithms optimize the kite's flight path to maximize the traction force generated. This traction force is then transferred to the ship, assisting its propulsion.

The technology is primarily aimed at reducing the environmental impact of shipping by offering a supplemental source of power. Potential benefits include decreased greenhouse gas emissions, lower fuel costs, and reduced reliance on fossil fuels. However, factors such as wind availability, kite size, and ship type affect the actual fuel savings achievable.

The SkySails system is primarily intended for use on large cargo ships, tankers, and other commercial vessels. The technology has been tested and implemented on various types of ships, and is actively being developed to improve its efficiency and reliability.
