Mitsui O.S.K. Lines, Ltd. and its group company MOL Drybulk Ltd. announced their intent to install wind propulsion systems including Wind Challenger on a total of seven new building bulk carriers and multi-purpose vessels, which will be operated by MOL Drybulk.
Wind Propulsion System
Among the 7 vessels to be equipped with wind propulsion systems, 6 new bulk carriers will each be equipped with 1 Wind Challenger Construction contracts have already been signed with Oshima Shipbuilding Co., Ltd. for 3 of the 6 vessels, and preparations are underway for construction contracts for the remaining three vessels.
In addition, MOL Drybulk has decided to install 2 Ventfoils, a foldable and autonomous unit for wind-assisted ship propulsion, manufactured by EconoWind B.V. (headquartered in the Netherlands), on one of its new multipurpose vessels (Note 5) slated for delivery 2025 and operation under a time charter.
MOL has established the “MOL Group Environmental Vision 2.2” and has set the target of achieving net zero greenhouse gas (GHG) emissions by 2050. One of the key strategies to achieve this target includes the “introduction of clean energy, further energy-saving technologies,” and the group plans to launch 25 vessels equipped with the Wind Challenger by 2030 and 80 vessels by 2035.
MOL Group will contribute not only to the reduction of GHG emissions from its own group but also to the reduction and decarbonization of society as a whole through the safe management and efficient operation of its environmentally friendly fleet that combines wind propulsion technology, such as the Wind Challenger.
