The World’s Largest Rotor Rule will Make the Oil Tanker Tougher
Maersk Pelikan has got two 30 meter high rotoregels – the largest in the world. Together they will give the oil tanker a fuel saving of up to ten percent.
Rotoregel is based on the Magnus effect, which causes a rotating body to accelerate perpendicular to the direction of movement – such as a screwed soccer ball. On the one hand, a densification of the air molecules occurs, while on the other hand they are sparse or even diluted. Because the pressure on the pages is different, a force occurs. The rotor shaft is rotating cylinders that utilize the physical phenomenon to provide the ship with an additional push with the help of the wind. An example is the Vikingline M / S cruise color Viking Grace, equipped with a 25 meter high rotor rail.
Now, Maersk Tankers is in charge of technology. Their oil tanker Maersk Pelikan has got two rotor gels 30 meters high and five meters in diameter. The dimensions make them the largest in the world. Together, the sail will provide a fuel saving of 7-10 percent for a typical ship route. Every year, the Danish company spends about three billion dollars on ship fuel – and ten percent of that sum would correspond to a saving of 2.7 billion kronor a year.
The technology has undergone rigorous tests on land and in short, the first trip will be conducted where the sail can really be farest at sea. On board, representatives from Lloyd’s Register shall ensure that the measurements are carried out in a blameless way.
– This project breaks ground in the product tanker industry. Although technology development has been strong for decades, propulsion with winds on a product tanker can change the entire game plan. The new technology has the potential to help the industry offer a more competitive price to move customers’ goods around the world, and reduce environmental impact, “said Tommy Thomassen, Technology Manager at Marsk Tankers in a press release.
Ship transport accounts for 2.2 percent of global carbon dioxide emissions. Earlier this year, the industry agreed to halve the common emissions by 2050 by the International Maritime Organization. The rotor rule is provided by Norsepower. In the project, Maersk Tankers has also collaborated with the Energy Technologies Institute (ETI) and Shell Shipping & Maritime.
