PBCF & Wind Propulsion
With our long-established expertise in high energy-efficient technology and wind power technology, we contribute to reducing environmental impact through CO2 reduction and to marine conservation by reducing underwater noise.
PBCF（Propeller Boss Cap Fins）
PBCF improves propeller efficiency by weakening the hub vortex generated behind the rotating propeller and reduces fuel consumption by about 5%. On a large containership, for example, that adds up to a 9,000-ton reduction in annual CO2 emissions.
Another benefit of PBCF is the reduction of underwater noise in a specific frequency range by 3 to 6 decibels, as confirmed by water tank testing. This let to its selection as a vessel noise reduction technology in the “EcoAction Program” implemented by the Port of Vancouver, Canada.
Norsepower Rotor Sail
The Rotor Sail is an auxiliary wind propulsion system based on the Flettner rotor, which uses wind power, and was developed into a modern, sophisticated system by Norsepower.
It can reduce fuel consumption by an average of 5% ~20% with a corresponding reduction in CO2 emissions annually. The Rotor Sail is a product that can be installed on both newbuild and existing vessels, contributing to global environmental conservation.
Maritime Energy Efficiency Consultant
As a strategic subsidiary responsible for technology research and development within the Mitsui O.S.K. Lines (MOL) Group, we have been dedicated to research and development efforts related to emission reduction in shipping with a focus on mitigating global warming.
Our initiatives extend beyond underwater solutions, as we also focus on harnessing offshore wind power. We have independently developed the “ISHIN ship design” *1, which utilizes lift generated by the airflow around the ship’s hull to provide propulsion, reducing wind resistance around the vessel. Additionally, we have undertaken the development of a similar technology called “bow wind deflector” *2 specifically designed for container ships.
Furthermore, we are currently collaborating with the Mitsui O.S.K. Lines, Ltd. on their “FOCUS” project, which leverages operational big data. This collaboration aims to evolve into data-driven energy-saving solution development, further reducing emissions from vessels.
*1 Adopted on 4 vessels of the Mitsui O.S.K. Lines’ next-generation car carrier series ‘FLEXIE’ and 2 state-of-the-art LNG-powered ferries
*2 Bow Wind Deflector installed on the bow of the container ship ONE MARVEL to reduce wind resistance
