Fixed-pitch propeller propeller boss cap fins PBCF

for variable-pitch propellersships

Marine propeller PBCF (Propeller Boss Cap Fins) is an extra hub with small fins attached to propeller cap to increase power efficiency. It is being widely accepted for its economic value in fuel saving and low investment, especially for medium and large vessels. Fountom is experienced in designing such PBCF according to each ship’s arrangement to ensure the most power efficiency and hydrodynamic performance. The number of fins is usually the same as number of propeller blades, for (FPP) controllable pitch propeller, review of the propeller drawing is needed to decide if a PBCF can be added to it. Results to expect with Fountom PBCF installed Practical fuel consumption saving by ~ 5% (statistic under same vessel knots); Lower propulsion vibration; Smaller (almost none) rudder impact erosion from propulsion flow. Other standout features PBCF brings No certificates or approvals required from ship class societies; No adjustments to original shafting designs required; Easy to install with bolts just as conventional propeller caps; Suits for both propellers of new building ships and on-service ships.
