Underwater PBCF Installation in South Korea

Last month Hydrex installed Propeller Boss Cap Fins (PBCF) on a 289-meter tanker during the vessel’s stop in Mokpo, South Korea. A Propeller Boss Cap Fins (PBCF) can recover energy loss of a propeller hub vortex in the propeller’s backward flow. This decreases fuel consumption by 5% when operating at the same speed, or boosts speed by 2% with the same fuel consumption. A clear explanation of the benefits of installing a PBCF can be found here.
