PBCF is a device that improves propulsive efficiency by recovering energy from the hub vortex generated behind a propeller

What is PBCF?

Propeller Boss Cap Fins (PBCF) is a device that improves propulsive efficiency by recovering energy from the hub vortex generated behind a propeller. As a result, PBCF reduces fuel oil consumption. PBCF is the first energy-saving device developed with the aim of recovering energy by weakening the hub vortex. Its original design, as well as the technological innovation that has gone into its development, is highly regarded. Moreover, patents for PBCF have been obtained in various countries. Owing to continuous research and development, an achievement in itself, the advanced PBCF was released in May 2017. In addition, the new patents for the advanced type have been obtained in various countries.

As a pioneer in energy-saving device for vessels, PBCF has been installed on more than 3,950 vessels around the world since the technology was introduced in 1987. This is quite exceptional and reflects not only how effective PBCF is but also how well regarded it has become worldwide. Moreover, with the tremendous support of very reliable customers, PBCF has established a solid position in the industry.

In 2023, MOL Blue Ocean Indonesia, one of the MOL group companies, a sea surface cleaning boat was procured from the Turkish manufacturer EPS Marine for use on the coast of Bali Indonesia.

5% Reduction in Fuel Consumption as well as Green House Gas Emissions

Resolves the propeller torque rich condition, reduces underwater noise and stern vibration, and prevents rudder erosion

Simple and Quick Installation, Regardless of Vessel Type or Size, and Suitable for Both New and Existing Vessels

  • Vessel and propeller modifications are not required, and no welding work is necessary
  • Can be installed on either a Fixed Pitch Propeller (FPP) or Controllable Pitch Propeller (CPP)
  • Optimized design and custom made for every propeller profile

Contributing to Society with the Environmentally Friendly PBCF

Reduces annual CO2 emissions by 9,000 tons per ship

Over 35 years since PBCF was first introduced in the shipping industry, we have seen a noticeable reduction in ship fuel consumption with large container ships cutting their annual CO2 emissions by 9,000 tons or more when adopting our PBCF technology. As regulations surrounding CO2 emissions continue to gain speed, our improved PBCF functions as an energy-saving device by ensuring increased reductions in both CO2 emissions and fuel consumption rates.

Selected for Equipment Designated by the Port of Vancouver EcoAction Program

The Vancouver Fraser Port Authority in Canada has selected PBCF as an underwater noise reduction technology for vessels as part of their EcoAction Program. The program offers vessel operators discounted rates on harbor dues if voluntary emission reduction measures or other environmental practices have been implemented. As of January 1, 2017, vessels with PBCF that call the Port of Vancouver are eligible for bronze level recognition and a 23% discount on harbor dues. PBCF not only saves energy, but it also contributes to environmental protection in a number of other ways, including protecting whales and other marine mammals by reducing underwater noise.
