Modern Steam Turbine Plant in New American Tanker HE Standard Shipping Co.’s (subsidiary of Standard Oil Co. of New Jersey) new bulk oil tanker G. Harrison SMITH, was launched July 12 at the Kearny yard of the Federal Shipbuilding & Dry Dock Co. Mrs. G. Harrison Smith acted as sponsor before a large gathering of officials and friends. This latest addition to the Stand- ard Shipping Co.’s fleet is one of the most modern bulk oil carriers afloat, being built on the Isherwood brac- ketless system of longitudinal fram- ing, while the application of high steam pressures and _ temperatures to her machinery is in accordance with the most progressive develop- ments in marine propulsion. Her dimensions are: 543 feet over- all in length, 74 feet beam and 40 feet 6 inches in depth ‘tween deck height main to shelter deck 14 feet 8 inches. Her deadweight capacity is 18,000 tons on a 28 feet 6 inches draft and speed on trial is to be 11 knots. Capacity of main cargo oil tanks is about 706,000 cubic feet; capacity of summer tanks about 159,- 000 cubic feet. The hull is divided by 17 oiltight and watertight transverse bulkheads. There are 11 bulk oil tanks, pump room, fuel oil tank, forward hold and machinnery space. The forward hold is arranged for carrying ballast and the ’tween decks forward is ar- ranged for carrying stores or mis- cellaneous freight. A centerline bulkhead is fitted in the oil tanks extending from the keel to the shelter deck and expansion trunk bulkheads, one port and one starboard, extending from main to shelter deck. Wing spaces outside the expansion trunk bulkheads are divided into five compartments on each side, fitted up as summer tanks. The fuel oil tanks have a capacity of about 1300 tons. Forward there is a raised fore- castle containing carpenter’ shop, lamp room, paint room and_ store room. A bridge house is constructed amidship with steel bulkheads at each end. Quarters for officers, etc. will be provided in a steel house on the bridge deck. Above this house will be accommodations for the cap- tain, radio operator, etc. The wheel house will be equipped for the sperry gyro compass and automatic steerer. Quarters for the engineers, officers, petty officers and remainder of crew, galley and mess rooms are provided for in a steel deck house in ‘tween decks aft. The propelling machinery is lo- cated aft and consists of a De Laval steam turbine unit, driving a single screw. The main unit is of the cross compound type and is composed of one high pressure turbine and one low pressure turbine, in series, con- nected through flexible couplings to double reduction gears. The slow speed gear shaft is directly coupled Single Screw Turbine Reduc- tion Geared Tanker G. Har- rison Smith Launched at Federal Ship- building & Dry- Dock Co., Kearny, N. d., July 12, 1930 Ready for launching. Length overall, 543 feet; beam, 74 feet; depth, 40 feet 6 inch- es; draft, 28 feet, 6 inches; deadweight ca- pacity 18,000 tons. Speed on trial 11 knots MARINE REVIEW—August, 1930 to the line shafting. The astern tur- bine is arranged in the exhaust end of the low pressure ahead turbine. The normal rated capacity of the main unit is 4000 shaft horsepower at a propeller speed of 75 revolutions per minute although the unit will de- velop a maximum of 4400 shaft horsepower at 77% revolutions per minute. The low pressure turbine is designed to exhaust through the bottom of the casing into the con- denser, arranged athwartship under- neath. There are two Babcock & Wilcox oil fired water tube boilers, designed to deliver steam at 400 pounds gage pressure, at a temperature of 750 de- grees fahrenheit. Air heaters and a balanced draft system are provided. Each boiler is provided with four oil burners of the Todd mechanical ato- mizing type. A centenary celebration was held on July 4, 5 and 6 at St. Johnsbury, Vt., by Fairbanks, Morse & Co. to commemorate the first 100 years of building Fairbanks scales. Annual Life Boat Race The fourth annual world’s cham- pionship life boat race will. be held in New York on Labor day. It is thought that practically the same rules as last year will govern the coming race, with the exception of the question of greasing the bottom of the boats. Up to the present time the Norwe- gians have shown a marked supre- macy in this sport. The steamer Sup AMERICANO’S life boat crew won in 1927, a crew from the Maureatania in 1928 and in the last race the Sup AMERICANO repeated their victory al- lowing them two legs on the Todd trophy which at the present time is held by the agents of the line, Garcia & Diaz. If a boat from this line is victorious this year, Garcia & Diaz will be the permanent owners of the Todd trophy. This race attracts large crowds each year and has grown to be an outstanding sporting event in the marine world. 25
