Mitsui O.S.K. Lines, Ltd. announced that its Propeller Boss Cap Fins (PBCF), sold by its group company MOL Techno-Trade, Ltd. was certified as the “Best-selling Energy-Saving Ship Appendage Brand (Cumulative)”, by Guinness World Records, and received the official certificate on December 23, 2021.This award is based on the cumulative 3,748 PBCFs sold (the sales record with 3,516 vessels including twin-screw vessels equipped with PBCF) as of the end of December 2020.PBCF was co-developed by MOL, West Japan Fluid Engineering Laboratory Co., Ltd., and Nakashima Propeller Co., Ltd.

Mitsui O.S.K. Lines (MOL) announced that its jointly developed Propeller Boss Cap Fins (PBCF) received the 2017 Nikkei Global Environmental Technology Award, which is presented by Nikkei Inc. The PBCF, which is a device that improves propeller efficiency by breaking up the hub vortex generated behind the rotating propeller and offers an energy savings of around 3-5% compared to similar vessels not equipped with the PBCF, was co-developed by MOL, West Japan Fluid Engineering Laboratory Co., Ltd., and Nakashima Propeller Co., Ltd. (called Mikado Propeller Co., Ltd. at the time), and is being sold by MOL Techno-Trade, Ltd. The PBCF has been sold for more than 3,200 vessels all over the world since 1987, when it started sales of the conventional PBCF.

Mitsui O.S.K. Lines, Ltd. today announced that Propeller Boss Cap Fins (PBCF) was selected as a vessel quieting technology by the EcoAction Program implemented by Port of Vancouver, Canada. PBCF was jointly developed by MOL, West Japan Fluid Engineering Laboratory Co., Ltd. and Nakashima Propeller Co., Ltd. (Note 1), and is being sold by MOL Techno-Trade, Ltd. The Vancouver Fraser Port Authority’s EcoAction Program offers discounted harbour due rate to vessels that have implemented voluntary emission reduction measures and other environmental practices. As of January 1, 2017, vessels equipped with PBCF and transiting to the Port of Vancouver will be eligible for bronze level recognition and a 23% discount in harbour dues.

Expanded premises for the World Maritime University (WMU) were inaugurated on Monday, May 19, 2015 in Malmö, Sweden, by IMO Secretary-General and WMU Chancellor Koji Sekimizu. WMU is an international educational institute for the maritime community, operating under the auspices of IMO. At close to 6,000m2, WMU’s new facility is nearly double the size of the previous Malmö campus. It provides a new auditorium, multiple research laboratories, seminar rooms and video-conferencing capabilities for hosting international conferences.

Michigan Wheel Marine and Nakashima Propeller Co. Ltd. have announced a new strategic partnership that is designed to combine their respective business strengths and promote cooperation in developing and expanding their global marine propulsion businesses. Negotiations have been ongoing for several months during which time business operations of both organizations have continued to expand, and it is on the foundation of this strength that the deal was signed. As part of the agreement Nakashima has acquired a 30% stock holding in Michigan Wheel Marine. It is the latest of several strategic moves that Michigan have made in recent years.

Propeller Boss Cap Fins (PBCF) is a propeller enhancing device, which is designed to cut fuel consumption and exhaust gases by up to five percent while incurring no additional maintenance cost once installed. The unit, according to H. Yumoto Manager of PBCF Div. Mitsui O.S.K. Techno Trade, Ltd., is now operational on 720 ship worldwide. The PBCF rectifies the propeller hub vortex and recovers rotational energy otherwise lost in the propeller slip stream. Increasing propeller thrust by over one percent and reducing propeller torque by over three percent, the PBCF reportedly results in fuel savings of up to five percent or compared to vessels operating at equivalent speeds but without the PBCF, alternatively, a 1.5 percent increase in speed at the same engine output.
