Hull cleaning
"...every dollar spent on hull cleaning and propeller polishing saves over $8 in fuel."
Our SCAMP equipment provides powerful cleaning without damaging the paint surface.
SCAMP brushes clean with a unique scything action using the sides of the bristles to provide a thorough yet gentler cleaning action, which is kinder to paint than standard methods involving harsh scrubbing with the tips of stiff bristles.
To create sufficient centrifugal force to clamp them firmly to the ship’s hull, most cleaning machines are forced to operate their brushes at above 500 rpm. Unlike these, the unique ‘clamping’ impeller in the centre of the Scamp machine allows brushes to rotate at 120 rpm, providing an opportunity for excellent cleaning with far more brush types with different configurations to suit each type of fouling growth. The result is excellent cleaning with better paint protection.
Without Scamp underwater hull cleaning, the power required
for a 50kDWT tanker to sustain 13 knots would increase from 6400 SHP to
almost 10,000 SHP. With Scamp underwater hull cleaning, the required SHP
is consistently held well below this level.
Guidelines for cleaning
•
Deal with barnacles and calcareous growth quickly.
• Flat wire removes barnacles and 75% of the
basal plates.
• Cleaning by
trained divers does not damage paint.
• Barnacles re-accumulate slower on a smooth
surface.
• If in
doubt clean.

The advanced Scamp hull cleaning unit
Scamp Underwater Hull Cleaning
Machines pack into a container for easy transportation onboard ship,
whether at sea or at port. The machine itself measures 6 feet (1.83m) in
diameter and houses three large rotating brushes. It travels underwater
across the ship’s hull on three traction wheels controlled by a
professional diver, or operated remotely. On command the machine will
advance, stop, reverse or hold a parallel line of motion as it makes a 5
foot (1.52m) cleaning swathe.
The rate of travel can be up to 90
feet per minute (27.43m) dependent upon the degree of fouling and a single
machine can clean up to 450 square feet per minute (1.52m) of the vessel’s
hull surface area. With its saucer shape and action of an impeller, the
machine clamps to the hull surface with a net force of 570 kgf (5595
newtons), allowing it to be used effectively against tidal forces of up to
three knots.
Scamp Underwater Hull Cleaning Machines are approved
for use at most oil tankers terminals as well as the most stringently
controlled harbours since independent studies have shown that their
operation does not impact on their water quality. Where there is less call
for hull cleaning operations, this service is performed with smaller
underwater hull cleaning equipment.
