At ABB Hirbo Systems power is a variable. Performance is a constant.

Who's been in power for 70 years?

In 1923 there came a day that changed the life of diesel engines and their dull existence. The advent of the turbocharger by BBC gave diesel performance a new dimension.

Since that time, over 265 000 turbochargers have given their engines the exhilarating sensation of approaching quadrupled power. Presently, more than 150 000 units plough the waves, ride the rails or keep the voltage humming. From 70 years of operating experience ABB Turbo

Systems can offer its customers a wealth of knowledge unparalleled by any other supplier.

And your bonus? Our immense know-how has brought efficiency up to near 75%. And each year, millions of Swiss francs are invested to further perfect supercharging technology and the materials employed.

We are ABB Turbo Systems. At 70, we're fresher than ever before.

Burlington, Iowa. The boat is pow- ered by a pair of John Deere model 6059T engines through Twin Disk

MG506 gears. The engines develop 163 brake hp each, turning 2.25- inch stainless steel shafts and 28- inch by 22-inch four blade propel- lers. By locating the propellers in tunnels, the vessel was able to meet the requirement that it operate in less than 33 inches of water. The engines are keel cooled and have dry exhausts.

The rudders are controlled by a full follow-up, lever-operated steer- ing system. The operator positions the steering lever to the angle he wants the rudders to be, and the rudders move to that angle. The boat has two main rudders and four flanking rudders, controlled by two separate levers.

A 2,000-gallon cargo tank can transport fuel to the dredge and other equipment. The tank was de- signed as a separate, drop-in unit, and can be removed for unrestricted access to the tank and hull for clean- ing, painting and major repairs. The cabin is removable for transporta- tion by highway, or for unrestricted access to the engines with a crane.
