Mitsui OSK Lines Techno-Trade’s (MOL Tech) propeller boss cap fins (PBCF) device has won an award for environmental impact-reducing technology
PBCF, an energy-saving device attached to the propeller of a vessel, breaks up the hub vortex generated behind the rotating propeller. MOL said this can result in energy savings of 3% to 5% compared to an identical vessel not equipped with the device. Higher fuel efficiency in turn reduces greenhouse gases emissions reducing the shipping industry’s environmental impact.
PBCF was co-developed by MOL, West Japan Fluid Engineering Laboratory and Mikado Propeller (now Nakashima Propeller). The boss cap fin is no new entrant into the market, having been introduced in 1987, and has been installed on over 3,400 vessels, including vessels owned by MOL and its group companies.
In 2017, MOL Tech, MOL, and Akishima Laboratories (Mitsui Zosen) jointly developed a new type of PBCF, featuring a refined fin shape and height to further enhance its energy-saving effect.
PBCF was also highlighted by the Canadian port of Vancouver’s Eco Action Program for its reduction of underwater noise, which has been shown to have a detrimental impact on sea life.
MOL Group said it will continue to expand its “environmental and emissions-free businesses” to support environmental conservation at sea and in ports all over the world, and will step up its efforts through the company’s Ishin Next smart ship project.
