fixed Kort nozzles. Twin rudders, fitted behind each propeller, are powered by hydraulic steering gear to improve steering and per- mit shaft withdrawl without re- moving the rudders. Total pro- pulsion brake horsepower is 4,860 maximum.

There are two 99-kw, 230-V, 3-phase generators driven by 8Y- 71 Detroit Diesel engines. Each unit is capable of supplying all power requirements for the aux- iliary equipment and house elec- trical loads.

Deck equipment consists of a 160,000-pound line pull towing winch driven by a 6V-71 Detroit

Diesel equipped with 2,400 feet of 2-inch wire rope and an aux- iliary drum; a 1,000-pound stock- less anchor and anchor windlass; and a deck capstan on the aft deck for handling tow gear. The bilge/ballast and fire systems pip- ing are all interconnected with a Barnes 25ICU-1 pump servic- ing each system. Separate mani- folds for the bilge system and ballast system are located in the engine room. Five fire stations are located two in the engine room; one main deck (port side) ; one fo'c'sle deck (stbd. side) ; and one upper deck (port side). Each fire station has 50 feet of hose and a combination stream/fog nozzle.

Executive Appointments

Energy Transportation Corpo- ration of New York City has taken delivery of a tug and 420- foot notched-stern barge for the transportation of liquefied am- monia in the Gulf Coast area.

The tug/barge will be operated by Energy Ammonia Transporta- tion Corporation, a subsidiary, under long-term time charter to

International Minerals & Chemi- cal Corporation.

The barge Energy Ammonia was constructed in two phases.

The steel structure and deck ma- chinery were built at the Modec

Louisiana Shipyard in LaRose,

La., in 1981. It was then towed up the Mississippi to Memphis,

Tenn., where the trunk deck was removed, cargo tanks construct- ed, insulated, and installed, and a cargo-handling system installed by Chicago Bridge & Iron Com- pany.

The cargo system was tested following a tow down the Missis- sippi to the Baton Rouge area where the barge met the tug En- ergy Altair and loaded its first cargo of ammonia for delivery to the International Minerals &

Chemical Corporation terminal in

Tampa, Fla. It is unmanned and the cargo liquefaction system is designed for fully automatic op- eration.

The Energy Ammonia is 420 feet long, with a beam of 78 feet, and a depth to the main deck of 28 feet. The notch is 48 feet long.

The tug Energy Altair was built by Bollinger Machine Shop and Shipyard, Lockport, La. Its principal characteristics are: length, 120 feet; beam, 37 feet; and depth, 18 feet. The tug is equipped to push when set in the deep notch of the barge or tow on a hawser.

Accommodations are provided for 11 people and the vessel is equipped with an upper and lower pilothouse. The upper pilothouse is used when in the notch and the barge is light to attain proper visibility. The lower pilothouse is used when in the notch and the loaded barge's draft allows proper visibility or when towing on a hawser.

Both pilothouses are equipped with a gyrocompass, radar, Loran

C, VHF radio, depth sounders, searchlights, and in addition the lower pilothouse has a satellite navigation unit and a single- sideband radio.

Two 12-cylinder ALCO diesel engines coupled to Reintjes 5 to 1 reverse reduction gears pro- vide propulsion power. They drive 108-inch-diameter propellers with
