(May 31st Certification Ceremony)

Mitsui O.S.K. Lines, announced that Propeller Boss Cap Fins , an energy-saving device attached to the propeller cap of a vessel, sold by MOL Group company MOL Techno-Trade, has been recognized for its pioneering role in technologies that contribute to the decarbonization of the shipping industry, in the past and the future. PBCF earned certification under “Marine Engineering’s Wake – Achievements of Predecessors for the Future” from the Japan Institute of Marine Engineering, one of the nation’s three major ship- and ocean-related societies

PBCF, co-developed by MOL, West Japan Fluid Engineering Laboratory Co., Ltd., and Nakashima Propeller Co., Ltd.(called Mikado Propeller Co., Ltd. at the time) in 1986, is an energy-saving device that reduces a vessel’s fuel consumption by an average of 3-5%. PBCF improves propulsion efficiency by eliminating the hub vortex generated behind the propeller. The device also reduces CO2 emissions by more than 9,000 tons annually when installed on a large containership. In December 2021, PBCF was certified Guinness World RecordsTM as the “Best-selling Energy-Saving Ship Appendage Brand (Cumulative),” by , and as of May 31, 2024, the number of PBCF-equipped vessels reached 4,178. It is calculated that PBCF has contributed to a cumulative reduction of about 67 million tons of CO2 emissions to date. Even now, 37 years after its development and commercialization, PBCF use continues to grow as its value is reaffirmed with the rise in environmental awareness.

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. This release is in line with the strategy to achieve this target, “introduction of further energy- saving technologies.” The MOL Group will achieve sustainable net zero GHG emissions and contribute to the realization of a low-carbon, decarbonized society, with concerted effort throughout the group.
