PBCF & Wind Propulsion

PBCF is a device that improves propulsive efficiency by recovering energy form the hub vortex generated behind a propeller. As a result, PBCF reduces fuel oil consumption, underwater noise, stern vibration and prevents rudder erosion. PBCF can be installed easily on both new buildings and existing vessels. Also, PBCF can save 2-3% energy when combined with Energy-Saving Ducts, Pre-swirl fins and others. And it is effective when combined with Rudder-Bulb which is said to have similar hub vortex reduction effects to PBCF. PBCF has been installed on more than 4,400 vessels around the world since the technology was introduced in 1987. Our PBCF is the best-selling and most reliable Energy Saving Device for ships.
