Leading innovative solutions to reduce fuel consumption and emissions for today's global shipping fleet.

Magnuss is a maritime technology firm that provides modern auxiliary wind propulsion for global shipping. The Magnuss VOSS or Vertically-variable Ocean Sail System is a proven and reliable fuel saving technology, supporting the de-carbonization of the shipping industry. The VOSS is an improved version of the Flettner rotor (a spinning cylinder that harnesses wind power to propel a ship) and enables significant reduction of both fuel costs and greenhouse gas emissions of ships. The patented VOSS technology can save vessels up to 50% in fuel costs – a line item that often represents more than two-thirds of a ship owner's/operator's annual expenses. Magnuss' customers include leading industrial companies and global shipping organizations. Virtually all existing cargo vessels and new builds can be retrofitted or outfitted with the Magnuss VOSS. This addresses major problems facing the global shipping industry, which is past the tipping point in terms of energy consumption and environmental impact. Magnuss aims to make the highly polluting shipping industry economically efficient and environmentally friendly.
