JULY 31, 2014 — Last month Hydrex installed Propeller Boss Cap Fins (PBCF) on a 289-meter tanker during the vessel’s stop in Mokpo, South Korea.

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.

By performing the PBCF installation on-site and underwater, the owner of the tanker could immediately start enjoying the fuel savings the system offers without waiting for the vessel’s next scheduled drydocking to have the PBCF installed.

Hydrex says that calculations show that the owner will have earned back the cost of the underwater installation in about eight weeks.
