The savings we delivered 4 years ago are

FOUR TIMES GREATER today!

This ad appeared in major marine publications in 1976. fuel savi

At todays high fuel costs these savings can be up to $1,000,000 per vessel,** making SCAMP® hull cleanings an essential part of your profit program.

If your vessel has been in service six months or more contact us immediately. underwater hull cleaning services

An EXXON Corporation study determined actual cash savings from regular hull cleanings with

SCAMP® equipment

JJCIK NET FUEL SAVINGS ATTAINABLE 24 MONTH DRY DOCK CYCLE

At Constant 21 MDWT 50 MDWT 250 MDWT

Speed ot Diesel Steam Steam 11 Knots $31,000 $127,000 $144,000 12 Knots $33,000 $141,000 $161,000 13 Knots $35,000 $157,000 $188,000 14 Knots $38,000 $185,000 $228,000

The net savings represent total tuel savings from regular hull cleanings and delay costs based on 4 to 16 hour cleaning periods For example, for a

VLCC. the savings amounted to 6 tons of fuel pe' day or $36,000 per round trip

The following chart illustrates typical fuel savings of a 50 MDWT vessel operating at a reduced speed of 11 knots as an example

Increase of shaft horsepowe consumption become neces. hold speed at 11 knots due hull and propulsion plant efficiency as time elapses Since regrgAh of foul ing takes place after eacrrcleamng, maximum net savings are realized from a regular SCAMP hull cleaning program In the preceeding example, net savings (fuel savings less SCAMP hull cleaning costs) were $127,000

Optimum cleaning programs are; every round trip for long-haul VLCC's and every four months for smaller vessels commencing at the onset of fouling, about 10 to 12 months after dry dock

A SCAMP hull cleaning program returns fuel savings many times greater than the cost of the cleanings even when operating at reduced speeds

Since its introduction, over 1600 vessels have been cleaned by

SCAMP units. Many ship operators bank on it.
