ECOSHIELD
ULTIMATE PROTECTION
PERMANENT PROTECTION FOR RUDDERS AND RUNNING GEAR
FROM CAVITATION DAMAGE, EROSION AND CORROSION -
THE ECOSHIELD DIFFERENCE
COSTLY DAMAGE TO RUDDERS AND RUNNING GEAR
C
avitation damage, erosion and corrosion can
cause havoc to rudders, Kort nozzles, thruster
tunnels, twisted fins and other running gear.
This damage to the vessel's rudder and running gear has
become a way of life with no permanent solution in sight.
Traditional protective coatings, even when supported with
sacrificial anodes, may hold up for a while, but it is not
long before the paint is cut through and destroyed, the steel
exposed, and pitting and corrosion appear.
Rudder repairs in and out of drydock can be major
expenses to a shipowner/operator.
The high-powered forces of cavitation can seriously
damage poorly protected rudders and running gear.
In extreme cases the whole rudder can disappear. Usually
rudders, thruster tunnels, nozzles and other running gear
become badly pitted and require repair, either underwater
with the ship afloat, or at the next drydocking.This can be
very expensive and cause delays.
In-water welding repairs are costly. Time in drydock is
extended with each day the ship is laid up, costing the
owner/operator not only the drydock fees but the higher
cost of having the ship out of service.
This situation with rudders and running gear has continued
since metal was first used for these parts of ships. The
rudder in particular, because of its position directly behind
the propeller, has been prone to the damage caused by
cavitation.
Many solutions have been tried but with little success. A
real solution to cavitation damage would save shipowners/
operators a great deal of money, time and worry.
