Norsepower Rotor Sails
has been issued the first-ever design type approval for onboard wind propulsion
. The rotor sails
aid considerably to the propulsion
of the motoring of the ship thereby reducing the amount of fuel
consumed by up to 20%.
With the International Maritime Organization's strategic [IMO]s vision to reduce maritime greenhouse gas (GHG) emissions as soon as possible and to phase out GHG emissions completely by the end of this century, one will see a lot more wind-assisted powered vessels, and carbon neutral fueled propulsion systems. The aim is to reduce total emissions from shipping
by 50% in 2050, and to reduce the average carbon intensity by 40% in 2030 and 70% in 2050, compared to 2008.

The next time you see a large cargo ship on Starboard tack with large rotating cylinders be prepared to determine if you need to give way because it may be a sailing vessel, a very large sailing vessel, but likely it will be motor
sailing. One will need to look for day shapes [a black, pointy-end-down cone] to determine if they are motor
sailing; if they are NOT displaying an inverted black cone then one should presume they are just sailing, [not a power vessel], and at night one will be looking for red over green lights to indicate they are a sailing machine.
We be calling merchant marines, sailors again.
Someone is going to paint
those rotor sails with red and white spirals so as to make them look like a barbershop sign.
Hmmm, so I wonder if Maersk will become a corporate member
to yacht clubs.
