Maritime shipping technology firm leading innovative solutions to reduce fuel consumption and emissions for today's global shipping fleet

Magnuss is a maritime technology firm that produces a suite of fuel efficiency technologies to reduce the energy consumption and emissions of today’s global shipping fleet. Chief among them is the Magnuss VOSS ™, or Vertically-variable Ocean Sail System, a retractable auxiliary wind propulsion system earning critical acclaim for its innovative design and fuel savings potential. The VOSS is a modernized version of the Flettner rotor—a spinning cylinder that harnesses wind power to propel a ship. 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, and the VOSS™ design is scalable and applicable to over 50,000 vessels worldwide. Virtually all existing cargo vessels and new builds can be retrofitted or outfitted with the Magnuss VOSS™. Magnuss aims to make the highly polluting shipping industry economically efficient and environmentally-friendly.
