Airseas macaron NSN WFG


Inside Alveole 12

Airseas was founded in 2016 in Toulouse by two Airbus engineers, with the ambition of transferring their aeronautical expertise to develop Seawing, an automated kite system designed to tow ships using the power of the wind. Airseas has received an initial order from Airbus, followed by five orders from Japanese shipowner 'K' Line between 2019 and 2022. The company is based in Nantes since 2021, and Seawing is currently finalising its first tests on a Louis Dreyfus Armateurs ship, chartered by Airbus.

Avel Marine is an association which will launch low-carbon local freight transport, by combining local river-sea exchanges, regardless of the size of the ports considered, and land collection / distribution in the hinterland of ports. A first experiment is planned on the Rance Maritime and another is being prepared on the Breton canals. A first boat, 19m10 long, is being decarbonized: auxiliary sails, electric propulsion, green electricity. Avel Marine is currently targeting non-perishable local products: canned food, drinks, clothing, cleaning products, etc.

Inside Alveole 12

AYRO is a French company which designs and manufactures Oceanwings: a wind-assisted propulsion system. It is an automated wingsail for the hybrid propulsion of ships. It is safe, simple and automated so that it does not require skills traditionally needed to sail. Oceanwings reduce fuel consumption up to 45% and C02 emissions as much, enabling shipowners to improve their cost competitiveness and to comply with the coming environmental legislation. As part of the design of the wingsails and to support its customers on their projects, AYRO carries out engineering studies and is also able to provide its customers with aftersale maintenance and data support via routing system and control software.

Beyond the Sea

Outside & Inside - Alveole 12

Created by Yves Parlier, Beyond the Sea® develops and markets kites, designed to tow all types of vessels (from pleasure boats to the largest maritime transport vessels). Our towing systems use the force of the wind in addition to the engine. Our kites reduce the fossil fuel consumption of ships and their greenhouse gas emissions by an average of 20%. Our SeaKite system is fully automated, from sending to retrieving the kite. It is installed on our laboratory catamaran and demonstrator The SeaKite. It is intended for professional use (fishing, transport...) as well as for pleasure boating. LibertyKite is a self-stable kite intended for recreational and/or safety use as it is a simple to install emergency propulsion system.

Our mission, since 2011, is to act to decarbonize maritime transport by using the power of the wind for a more sober, less dependent on hydrocarbons, and more transparent mode of transport. Sailing, as the main propulsion, is a lever for economic development in trade and allows us to look for a real energy transition to meet the climate and energy challenge. Sailing-cargo ships offer a modern, cost-effective, reliable and optimized logistics solution based on the innovative use of proven technologies. They are naturally a cost-effective and competitive offer. The first generation, the Phenix class, with a capacity of 1000 tons, will be launched in December 2023 (first ship). A sister-ship will arrive in 2024.
