FAQ
Wind power is free, unlimited, and represents a form of substantial propulsive energy.
We feel that wind energy has a role to play in the shipping industry of the future.
Here are some answers to the most frequently-asked questions:
On which types of cargo ships can sails be installed?
Can sails be installed on existing ships?
Yes and it’s an essential part of ensuring a successful energy transition in the shipping sector; to date, there are
around fifty thousand cargo ships in the world and their lifetime is around 30 years.
Can sails be installed on all types of cargo ships?
No, some types of ships are not at all suitable, starting with those which perform offshore work or ships operated at speeds above 17 knots (RoRo ships, passenger vessels, large container ships).
Can sails be used even on the largest cargo vessels?
Yes, no problem.
However, their tonnage (cargo capacity, displacement) increases tremendously with their length.
It is not possible to increase the size of the sails in the same proportions.
What about sailing times?
Is this type of transport slower?
No, the sail ships that we are developing have hybrid solutions using sails and engines.
The speed of the ship remains constant and we guarantee the same sailing speeds as a “conventional” engine-powered ship, with the added benefit of reducing the consumption of fossil-derived fuels.
If the winds are not favourable, will the ship be late?
No, if wind conditions change, the ratio of operation of the sails and engine will vary, but sailing schedules will be respected regardless of the weather conditions.
What are the savings?
Does it cost more?
No, we are able to offer the same transport prices as “conventional” ships.
Building a ship with sails costs more than a conventional mechanical engine-driven ship, but the fuel savings made offset the additional manufacturing costs.
How do you calculate the CO2 savings made?
These savings vary between 20% and 50% depending on the operating region and the type of ship.
Based on ship performance forecasts calculated by our design office and weather statistics from previous years, we can evaluate the average achievable savings for each region and season.
