Maersk put Flettner rotor sails back on tankers to cut bunker fuel
Maersk Tankers fitted two 30m rotor sails on a product tanker, expecting 7-10% lower fuel and emissions via the Magnus effect.

那一手
Decades of engine development left wind propulsion in the past, but rising fuel and carbon costs changed the economics of the kind of free energy a ship already sails through.
Maersk Tankers installed two 30m rotor sails on the product tanker Maersk Pelican in Rotterdam, built by Norsepower and based on the Magnus effect, expecting 7-10% lower fuel use and emissions.
The sails were already on three commercial vessels; the project measured long-term financial and technical viability, with partners including Shell Shipping and Maritime and the Energy Technologies Institute.
为什么管用
- Sails supply free propulsion from the wind the ship already meets.
- A 7-10% fuel cut is a straight cost and emissions saving.
- Retrofitting an existing ship avoids building a new one.
可以搬走什么
A century-old mechanism someone wrote off can be the cheapest innovation available, if the cost that made it obsolete has changed.
后来呢
The project was called a first for the product-tanker industry. Maersk Tankers later placed orders for more wind-assisted propulsion for several tankers, and the wider dry-bulk and tanker sector is retesting an idea that has been around since the 1920s.
