Rigid spark plugs to reduce fuel consumption

The rigid sail system, similar to the wing of an airplane but installed vertically, uses the (free) wind so that ships consume less fuel. This sail system is compatible, they can be installed in 85% of the world fleet. From fishing boats to tankers. A rigid, orientable, folding, automatic and autonomous sail.

The 85,000 ships in the world today emit as much CO2 as Germany as a whole. The world’s 16 largest ships emit as much sulfur as the world’s fleet of cars. Some data to give you an idea of ​​what we are dealing with and the importance of making maritime mobility more sustainable.

The rigid sail has an internal steel frame, lined with fiberglass. It is adjustable, can be rotated 360 degrees and foldable, at deck level, to avoid trouble in bad weather or in port areas.

The system is fully automated, the position of the sail changes according to the wind, seeking maximum efficiency.

Characteristics Rigid sailboats.

Among its characteristics and advantages we can highlight:

  • Using an asymmetric aerodynamic profile, twice the thrust compared to its competition.
  • Foldable on the boat deck, so as not to obstruct visibility when maneuvering in port.
  • He can turn.
  • The size and / or height limit is structural.
  • Minimal interference and impact on the cargo capacity of the vessel.
  • It is completely autonomous, no crew is necessary to operate it, the system works alone.
  • Hydraulic and mechanical control.
  • Materials commonly used in navigation.
  • Tested and safe in the harshest weather conditions.
  • The installation pays for itself in 4 years, if we are talking about large boats, and in 3 years, if we are talking about smaller boats.
  • Minimum maintenance system.

Fuel savings and reduced emissions.

Also depending on the routes and the type of boat, this system offers fuel savings of over 40% without changing existing routes or transit times.

For the Handysize boat, by keeping the crossing time constant, speed 14 knots, it is possible to achieve a fuel saving of 12.5% ​​per integrated sail. With 3 candles, the savings rate drops to 42%.

Rigid Bound4blue candles

Its first two installations will be on the ship “La Fura del Baus” (cargo ship 70 meters long) and a fishing boat (40 meters) from a Galician shipowner.

Behind this project are the Spanish aeronautical engineers José Miguel Bermúdez, David Ferrer and Cristina Aleixendri. Together they founded Bound4blue, based in Rubí (Barcelona) and Santander (Cantabria).

Bound4blue received the CaixaBank EntrepreneurXXI Award for industrial technologies.
