skysails

SkySails is a German company specializing in the development and application of automated auxiliary sail systems for commercial ships. Founded in 2002 by Stefan Seefeld and Stefan Breuer, the company is headquartered in Hamburg. Its technology aims to improve the efficiency and sustainability of maritime transport by reducing fuel consumption and emissions through wind-assisted propulsion.

The core innovation of SkySails is the use of high-performance, lightweight kites that can be deployed from a ship’s deck. These kites, typically made of durable materials like polyester or nylon, are connected to the vessel via a tether system. By harnessing wind power, the kites generate additional thrust, allowing ships to travel faster with less engine power or cover the same distance using significantly less fuel. The system can be adjusted dynamically to optimize performance based on wind conditions, ship speed, and cargo load.

SkySails has conducted numerous trials and demonstrations with various shipping companies, including the German shipping group Hapag-Lloyd and the Norwegian company Wallenius Wilhelmsen. These collaborations have shown promising results, with fuel savings of up to 20% reported in certain conditions. The technology is particularly beneficial for container ships, bulk carriers, and other large vessels operating in open waters where wind resources are abundant.

Beyond fuel efficiency, SkySails contributes to environmental sustainability by reducing greenhouse gas emissions, a critical concern in the global shipping industry. The system is designed to be modular and compatible with existing ship designs, making it a practical solution for retrofitting older vessels. However, challenges such as weather dependency, regulatory approvals, and operational integration remain areas of ongoing development.

SkySails operates under the principle of sustainable maritime transport, advocating for the integration of renewable energy sources into traditional shipping practices. The company continues to refine its technology and expand its partnerships to promote wider adoption of wind-assisted propulsion in the global fleet.
