Interlake's De Lancey

Christened (continued from page 12) pitch from the pilothouse and en- gine room. Separate control units connected to the central pilot- house unit are located on both the port and starboard bridge wings.

Maneuvering the huge 1,000- footer is simplified by the twin screws and the arrangement of a rudder behind each propeller.

The ship also can be steered by varying the speed of each engine.

In addition, a 1,500-hp Bird-

Johnson electrically driven bow thruster facilities docking by moving the bow to the right or left in much the same fashion as a tugboat.

Reversing is accomplished through the controllable-pitch propellers; the engines do not re- verse. This system greatly short- ens the time to generate a re- verse response as compared with turbine-powered systems.

Due to the De Lancey's ail-aft design and overall height of 118 feet, a personnel elevator whisks crew members from the engine control room level up the five decks to the level below the pilot- house.

The 31-man crew is housed aft in modern, comfortably furnished quarters. Officers have single rooms, with only some of the crew sharing a room. Living quar- ters, the galley, and engineer's control compartment are all air- conditioned.

The onboard St. Louis ship

FAST sewage treatment plant, which meets stringent Federal standards, produces completely clean effluent for discharge, or for temporary holding while the vessel is in waters where dis- charge is prohibited by local reg- ulations.

Dravo Negotiating To Buy

Operating Assets Of

Nilo Barge Line From Olin

Dravo Corporation, Pittsburgh, announced recently that it is ne- gotiating a definitive agreement to purchase substantially all of the operating assets of Nilo Barge

Line, Inc., a subsidiary of Olin

Corporation. Directors of Dravo and Olin have approved a letter agreement outlining terms of the cash transaction, the amount of which was not disclosed. Assets covered would include 180 dry cargo barges, five towboats, a trans-Gulf operation, and related supporting assets.

Robert Dickey III, Dravo chair- man and president, said that the proposed acquisition would signif- icantly increase the Pittsburgh- based firm's overall involvement in water transportation. The di- versified organization already owns one of the larger barge lines on the Mississippi-Ohio River sys- tem, Dravo Mechling Corporation, which operates a fleet of 18 tow- boats and 575 barges.

Brochure Available On

Foster Wheeler Boilers

And Auxiliary Equipment

Foster Wheeler Energy Corpo- ration, Livingston, N.J., has just published a 16-page, full-color brochure describing and illustrat- ing its full range of marine boil- ers and auxiliary equipment in- cluding condensers, steam jet air ejectors, inert gas generators, and flue gas scrubbers. The book- let contains specifications, dia- grams and many full-color, cut- away illustrations.

Foster Wheeler offers a com- plete range of boiler designs.

Each unit is individually engi- neered to achieve the operating requirements of the specific ves- sel it will be powering.

Starting with the basic "D" type boiler, each derivative de- sign was developed to make the greatest contribution to vessel op- erating profit, considering cargo capacity, manning, financing, and life cycle. Foster Wheeler designs and manufactures other major marine power plant components and can integrate the boiler and these components into a power system that will generate the re- quired shaft horsepower in a most cost- and fuel-efficient way.
