We are pleased to introduce the globally recognized Mitsui PBCF Energy Saving Device, with over 3,600 installations worldwide. This best-selling solution delivers fuel savings and simultaneously increases vessel speed (VREF) under specific loads, providing measurable improvements in efficiency and emissions performance.

About the PBCF
The PBCF (co-developed by MOL, West Japan Fluid Engineering Laboratory Co., Ltd., and Nakashima Propeller Co., Ltd.) was the first commercial device to recover energy wasted by the vortex formed behind a rotating propeller. It breaks up this vortex, increasing thrust and achieving energy savings of 3%–4%, alongside improvements to Rightship SCI, CII and GHG metrics.

Key Benefits of the PBCF

• Enhances energy efficiency by disrupting the hub vortex, reducing energy loss, and boosting propulsive efficiency.
• Improves fuel consumption and speed performance by optimizing energy transfer and minimizing drag.
• Easy installation, even afloat if required.
• Compatible with other Energy Saving Devices (e.g., pre-swirl fins, rudder bulbs, ducts).

Case Study: Combined Energy Saving Models
A combined model test conducted at Akishima Laboratories (Mitsui Zosen) Inc. for a Japanese-design Cape-size Bulk Carrier demonstrated the synergistic benefits of the PBCF and Schneekluth Ducts:

• PBCF alone: Energy savings of 2%–3% across the speed spectrum.
• Schneekluth Ducts alone: Energy savings of 5%–6%.
• Combined PBCF & Schneekluth Ducts: Energy savings of 6%–8%.

These findings emphasize the importance of selecting the right Energy Saving Device (ESD) to maximize performance and compliance with evolving industry regulations.

Why Choose the MOL PBCF?

• Proven performance with over 3,600 installations worldwide.
• Optimized, vessel-specific designs based on CFD studies, including RightShip 2.0 requirements.
• Validated through extensive model tests and operational data.
