New-generation sail maker Norsepower has struck a deal with French ship operator Socatra to retrofit a second tanker.

Norsepower will fit two 35-metre rotor sails on the 50,000-dwt MR tanker Alcyone (built 2022) in a move that is projected to cut emissions by 8%.

The Finnish company previously installed the rotor sails on the 110,000-dwt Maersk Pelican (built 2008) in August 2018 and a year-long trial found that it led to similar emissions savings.
