Underwater PCBF ECO CAP Installation

The Propeller Boss Cap Fins PBCF or ECO CAP is a device for propeller efficiency improvement that recovers energy loss of a propeller hub vortex in the propeller backward flow.

Furthermore an Eco Cap or PCBF decreases fuel consumption by 5% when operating at the same speed, or boosts speed by 3% with the same fuel consumption. Propeller cap with fins that rotate together with the propeller. It improves propulsive efficiency by weakening the hub vortex, and by recovering kinetic energy from the rotating flow aft of the propeller blades.

FN DIVING operating on-site and underwater, the Shipowner could immediately start enjoying the fuel savings the PCBF, ECO CAP, Energoprofin system offers.

Underwater bow thruster operation before dry dock

A unit with internal damage due to depreciation on normal use had to be overhauled in Dry Dock as the docking period was limited.

FN Diving arranged to take to the Thruster Unit prior to docking making sure the unit was ready and overhauled before the arranged docking.

FN Diving performs a wide range of repair or maintenance work on all types of thrusters.

The Complete unit can be removed and overhauled or re installed, propeller blades and seals can be replaced and specific repair work on any part of a thruster can be performed on-site.
