The first installation of an automated kite system for
wind-assisted propulsion on a commercial vessel was recently completed and will
begin trials early in the new year. The project, which is being undertaken by
Airseas, a company developed by the aviation industry’s Airbus, will see a
half-size demonstration version of the “Seawing” wind sail operating on
transatlantic voyages.
Airseas, which was founded in 2015 as a spin-off from
Airbus, looks to leverage the aeronautical experience and technology in developing
its sail kite to provide wind propulsion assistance for large commercial
vessels. The concept calls for the full-size version of the Seawing, a 1000m2
parafoil, to fly at altitudes of nearly 1,000 feet capturing the stable higher
altitude winds to assist vessel propulsion.
According to Airseas, over approximately 500 feet above sea
level the winds are more stable and stronger in strength. Their previous
research shows that the Seawing would have a pulling power of up to 100 tons
meaning it can contribute to propulsion for a ship of over 200,000 tons and
over 1,000 feet in length. They project fuel savings on average of 20 percent
by deploying the kite sail.
“A decade ago, we embarked on the ambitious project of
channeling our unique aviation expertise towards creating a cleaner and more
sustainable shipping industry,” said Vincent Bernatets, CEO and Co-Founder of
Airseas. “Today, I am beyond proud to see that vision becoming reality, with
our first Seawing ready. This first installation marks a significant milestone
not only for Airseas but also for wind and other renewable propulsion
technologies.”
The installation of the automated wind propulsion system was
completed aboard the 5,200 dwt Ro-Ro Ville de Bordeaux following collaboration
and testing with Bureau Veritas. The vessel, which is chartered by Airbus and
operated by Louis Dreyfus Armateurs transports major aircraft components
between France and the United States, was outfitted with a 500 m2 demonstration
version of the sail. Beginning in January 2022, they will commence six months
of trials during the vessel’s monthly transatlantic crossings.
“This important milestone follows three years of close and
fruitful collaboration on the development and early trials of the Seawing,
supporting Airseas’ safety-first approach and validating the reliability of the
system,” said Laurent Leblanc, Senior Vice President Technical & Operations
at Bureau Veritas Marine & Offshore.
This round of testing follows a month of testing on a
smaller scale 250 m2 version of the Seawing in April 2021. The company deployed
the sail on a barge in the south of France to gain critical operational data as
a step toward proving the concept. Longer-term, Airseas objective is to
equipment up to 15 percent of the world’s commercial fleet with the technology,
which they believe could result in an annual reduction of more than 40 million
tons of CO2 emissions.
