Start saving fuel with your propeller cone fin now

Propeller cap energy saving devices can recover energy loss of a propeller hub vortex in the propeller’s slipstream. This decreases fuel consumption from 3% up to 5% according to the manufacturers, and reduces cavitation on rudders and hulls.

Flexibility and speed are the watchwords for Hydrex when assisting a customer with this kind of operation. As soon as the propeller cone fin is ready for delivery, They can plan the installation based on the ship’s schedule. Because their divers perform these operations in a single day and during cargo operations, they have considerable freedom in choosing the best time and location for the installation.

A direct result is that an owner can instantly benefit from the fuel savings a propeller cone fin brings. He does not have to wait until the next scheduled drydocking for the installation.

Hydrex installs propeller cone fins underwater on any size and make of propeller, on both recently launched or older vessels. The company carries out these operations following the specific procedures required by the OEM involved, adapted for an underwater installation.

After a preliminary inspection, the divers remove the existing propeller cap and clean the flange where the device is to be installed. They then lower the new propeller cone into the water and position it on the propeller. The bolts are inserted with the correct torque and secured. Hydrex teams can work in shifts around the clock to finish the operation as quickly as possible.

The owner of the vessel can start enjoying the fuel savings the propulsion improving device creates right away. Not having to wait for the next scheduled drydocking to have the propeller cone fin installed can win him up to four years of fuel savings. Since he will have earned back the cost of the underwater installation in only a few weeks, the savings are considerable.
