Japanese shipping company Mitsui OSK Lines, Ltd. (MOL) on Wednesday announced plans to fit a second bulk carrier with the Wind Challenger hard sail system, which harnesses the power of the wind to propel the vessel, improving efficiency and reducing fuel consumption and emissions. .

MOL Group company MOL Drybulk Ltd. will operate the vessel, which will transport wood pellets for sustainable wood bioenergy producer Enviva Inc. and has signed a construction contract for the new vessel with Oshima Shipbuilding Co., Ltd. .

The vessel, scheduled for delivery in 2024, will be the second Wind Challenger-equipped vessel in the MOL Group’s fleet, after the one expected to enter service in October this year.

The Wind Challenger is a telescopic rigid sail that converts wind energy into propulsive force. Installing a Wind Challenger sail on merchant ships has the potential to significantly reduce fuel consumption, reducing greenhouse gas (GHG) emissions by approximately 5-8%. A bulk carrier for Tohoku Electric Power Co., Inc., the first vessel equipped with the Wind Challenger, is scheduled for delivery in October 2022.

MOL noted that it is also examining the feasibility of adopting Rotor Sails, an auxiliary wind propulsion system developed by Anemoi Marine Technologies Ltd, of the United Kingdom. The combined use of the Wind Challenger and Rotor Sails is expected to reduce GHG emissions by an average of 20%. , MOL said.
