per. The boom is set at a 25-degree angle to accommodate an underwat- er digging depth of more than 70 feet and a maximum dumping ra- dius of 113 feet.

The clamshell has an even more impressive working range. The 155- foot-long lattice-type boom is equipped with 50-yard bucket that has a maximum digging depth of 150 feet below surface. Maximum dumping radius is 120 feet.

The dredge will be controlled by a

P&H Electrotorque® solid-state DC system. Total connected DC-rated power of electric motors aboard the 5700 is 5,625 hp.

Working in either the clamshell or dipper mode, the Chicago will pro- vide a continuous operation, dredg- ing material and disposing of it without interruption, even if the disposal area is far from the dredg- ing site. The exceptional dipper power also enables the dredge to excavate extremely difficult materi- al that might otherwise have re- quired blasting.

The Chicago was designed for work in U.S. ports including dee- pening of harbors, as well as for operation in other ports throughout the world. The $30-million invest- ment in the new dredge and the two

Hydro-Dump barges is the largest single appropriation in GLI's 100- year history.

In addition to the main engine/ generator plant, there is one 450-kw

Caterpillar auxiliary generator and an emergency generator of 150 kw, also supplied by Caterpillar.

EXXON VALDEZ

National Steel

The 211,469-dwt VLCC (very large crude carrier) Exxon Valdez, built at the San Diego yard of Na- tional Steel and Shipbuilding Com- pany (NASSCO), was recently de- livered to her owner Exxon Ship- ping Company. The first of two

Alaska Class tankers to be built by

NASSCO for Exxon, she has an overall length of 987 feet, beam of 166 feet and maximum draft of 64 feet 6 inches. She is powered by a low-speed IHI-Sulzer 8RTA84 en- gine with a maximum continuous rating of 31,650 bhp at 78.9 rpm. A new design of BBC Brown Boveri

NTC254 power turbine is fitted to the engine, which the company claims could provide a fuel savings of up to four percent. The tanker is capable of maintaining an average speed of 16.5 knots.

Said to be the largest ship ever built on the West Coast, the Exxon

Valdez will transport 1.5-million barrels of crude per voyage from

Valdez, Alaska, to Panama, where the oil can be delivered to U.S. mar- kets on the Gulf and East Coasts.

Due to her large size, very efficient low-speed diesel engine and high degree of automation, the Exxon

Valdez will enable the Exxon Ship- ping Company to establish a new level of efficiency in the transporta- tion of Alaskan crude.

The NASSCO-designed Alaska

Class tanker is fitted with the most modern equipment available and meets the latest safety and environ- mental protection standards, in- cluding a segregated ballast system, an inert gas system, sewage treat- ment system, collision avoidance ra- dar and a back-up steering system.
