Startup 'OutSail Shipping' to develop 'sail' that reduces fuel consumption of ships by up to 20%
Developed a new sail ' Mirage ' that maximizes the use of 'sails' that have been removed from modern ships powered by engines, is attached to ships with engines, and reduces fuel consumption by up to 20% It has been.

OutSail Shipping, a startup led by CEO Alpan Lau and CTO Joseph Orebeek, is exploring ways to attach sails the size of a Boeing 747 to large container ships. If you watch the video introducing the sail 'Mirage' developed by Mr. Orebeek and others, you can understand its size.

'Mirage' is a major feature that it is 'retractable', and if it is rolled up small, it can be accommodated in the container.
It can be rolled up even after it is installed on the ship, so it can be folded when not in use and stretched only when the wind blows. If it is made smaller, it will be about 3 meters, and if it is made larger, it will be up to 60 meters.
Even if there is a bridge girder, it can be avoided.
Mr. Orebeek explains directly how to wind up.

Mirage is basically stored small with the same mechanism as a tape measure, and can be expanded as needed.
Although it looks flimsy, it is said that it will be reinforced with sheet metal when actually manufacturing.
The basic usage of Mirage is the same as sailing, with a slightly tilted sail receiving the wind from the surroundings and propelling it forward.
Örebeek said the International Maritime Organization has introduced new regulations to grade ships using a metric called Carbon Intensity (CII), so ships with lower ratings will have to slow down or use alternative, cleaner fuels. It is said that it has become impossible.
Therefore, Mr. Orebeek appeals that Mirage is useful. Mirage says it can reduce fuel consumption by up to 20% and can be easily removed and stowed without interfering with cargo loading and unloading operations.
The design is incomplete and Orebeek is asking for feedback.
