Mitsui O.S.K. Lines, Ltd. and its group company MOL Drybulk Ltd. today announced their intent to install wind propulsion systems including Wind Challenger(Note 1)on a total of seven newbuilding bulk carriers and multi-purpose vessels, which will be operated by MOL Drybulk.MOL has measured the performance of the Wind Challengeron a vesselShofu Marucontinuously on actual voyages andconfirmed that the Wind Challenger sail reduced daily fuel consumption by up to 17%*.

*The fuel saving and GHG reduction effect of the Wind Challenger depends on various conditions such as the type of vesseland the shipping route.

MOL Group will have a total of 9Wind Challenger-equipped vessels, bringing the total number of vessels equipped with wind propulsion systems to 11.

Among the 7 vessels to be equipped with wind propulsion systems, 6new bulk carriers will each be equipped with 1Wind Challenger Construction contracts have already been signed with Oshima Shipbuilding Co., Ltd. for 3of the 6 vessels, and preparations are under way for construction contracts for the remaining three vessels.

In addition, MOL Drybulk has decided to install 2Ventfoils, a foldable and autonomous unit for wind-assisted ship propulsion,manufactured by EconoWindB.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.
