Cargo Ship Completes Maiden Voyage Using Towing Kite
March 19, 2008
The two-month maiden voyage of the Beluga SkySails cargo ship was
successfully completed in mid-March, providing proof that its kite towing
system can cut fuel use by up to 20%. The first voyage focused on
perfecting the automated kite deployment system, so the kite was
deployed for as little as a few minutes and for as long as eight
hours. When deployed in strong winds, the kite pulled the ship with a
force equal to 20% of the engine power. The system is undergoing a
12-month pilot phase, and in the second half of that test period, the
kite will be deployed for longer periods of time. Once the pilot phase
is over, the 191-square-yard kite will be replaced with one twice its
size, which is expected to save about 5 tons of fuel per day, for a
daily operating savings of about $2,000. The owner of the ship, Beluga
Shipping GmbH, is currently building two larger cargo ships that it
plans to outfit with kites as large as 717 square yards. See the
SkySails press release.
