Butterworth Systems Receives IMCO Approval

The line of tank cleaning machines manufactured by Butterworth Systems (U.K. and USA) have received approval, in accordance with the latest IMCO requirements for the design of crude oil w a s h i n g systems. Effective August 30, 1978, the approval was made by the United Kingdom Department of Trade and Industry, and certifies B u t t e r w o r t h Systems equipment for use onboard the world's tanker fleet.

The BUTTERWORTH® fixedin- place tank cleaning machines reviewed by the Department of Trade and Industry are among the first to receive IMCO approval.

The machines may be used for a variety of tank cleaning applications, including water washing as well as crude oil washing (COW).

Included among the machines approved is the LAVOMATIC® SA tank cleaning machine, which features automatic, variable, and/ or c o n s t a n t speed controls for highly efficient cleaning in less time, using less washing fluids.

Deck-mounted, this single-nozzle, high-capacity machine is recommended for larger vessels. Its selective arc pattern demonstrates outstandng results in crude oil washing.

The BUTTERWORTH MP tank cleaning machine, designed for reaching difficult areas in complex tank structures, also meets IMCO requirements. This singlenozzle, high-throughput, fixed-inplace machine can be mounted in any location in any attitude and was specifically designed for installation on tank bottoms, where it will be submerged in the cargo.

Also approved for fixed-in-place a p p l i c a t i o n s are the BUTTERWORTH K and SK tank cleaning machines. These twin-nozzle machines clean tanks in the familiar and well-proven "ball of twine" pattern. The SK unit has an effective cleaning range of up to 70 feet, compared to the K machine's 30 feet. In addition, the larger SK machine handles a throughput of 45 to 50 tons per hour, compared with the K machine's throughput of 30 tons per hour.
