President-Elect Of SNAME Attends Chesapeake Section Meeting At ARCTEC Ice Model Basin Dravo Launches Record 300 Barges In 1972 P^WWIIW^HPi^iPiHPWIIWP The Chesapeake Section of The Society of Naval Architects and Marine Engineers held the third meeting of its 1972-73 technical program on November 21, 1972, at the Howard Johnson Motor Lodge in Laurel, Md. The program con- sisted of a dinner and technical presentation of a paper entitled "Design, Construction and Opera- tion of an fee Model Basin," by George H. Levine, David Benze, and James Peter, of ARCTEC, Inc. At the conclusion of the technical program, the membership recon- vened at the ARCTEC Ice Model Basin (AIMB) in Savage, where an icebreaking model test demon- stration was conducted. This combination of a technical paper followed by a practical ice- breaking -model test demonstration was attended by approximately 150 members, which indicated the high interest in the paper and the ability to see an ice model basin demon- stration. Roderick Edwards Jr., ARCTEC, served as the moderator of the technical session. Mr. Peter pre- sented the verbal discussion of the paper, which highlighted the num- • * * : : : • , ': * V > V V • : Pictured at the Chesapeake meeting, left to right: Phillip Eisenberg, president of The Society of Naval Architects and Marine Engineers; James J.

In addition, he discussed the build- ing facilities at ARCTEC, the mod- el basin construction and the ther- mal efficiency of the system. At the conclusion of the presentation, numerous questions were asked from the floor and answered by one of the co-authors, George Levine. Seth Hawkins, vice chairman, was pleased to report on the recent election of officers held at 'the an- nual meeting of SNAME in New York. Phillip Eisenberg, past chair- man of the Chesapeake Section, was elected president of the So- ciety. Other distinguished members of the Section who will serve in the Society are: E. Scott Dillon, Depu- ty Assistant Administrator for Op- erations, Maritime Administration, was elected a vice president of the Society, and John J. Nachtsheim, Chief, Office of Ship Construction, MarAd, was selected as a member of the executive committee. Each of these members has had a long and active role in the Chesapeake Section. For the 300th time in 1972, Dravo Corporation launched a barge into the Ohio River. The 300th barge (shown above) is one of thirty 200-foot-long covered hopper barges that will be delivered for service with Flowers Transportation Company, Greenville, Miss. With a total cargo capacity in excess of 300,000 tons, the barges built by Dravo in 1972 would stretch more than 1 1 miles, end to end. Dravo Corporation on December 27 launched its 300th barge of 1972, setting an all-time barge produc- tion record that is more than 50 percent better than the previous high of 184 launchings set in 1971. Robert Dickey III, president and chief executive officer of the di- versified engineering, manufactur- ing and construction company, said Dravo expects its total 1972 ma- rine equipment bookings to exceed $55 million —• some $20 million above 1971's record $35.8 million. At the end of the third quarter of 1972, Dravo had orders for 262 barges and five towboats with a total value of $46.2 million, Mr. Dickey said. The 300th is one of thirty 200- foot-long covered hopper barges that will be delivered for service with Flowers Transportation Com- pany, Greenville, Miss. During 1972, Dravo carried out a $3.5-million modernization and expansion program at its Neville Island barge and boatbuilding fa- cility near Pittsburgh, Pa., on the Ohio River. It included construc- tion of an enclosed 312-by-92-foot addition to the existing barge shop building and purchase of new pro- duction equipment. "We expanded our manufactur- ing facilities to keep pace with the growing demand for marine equip- ment," said Mr- Dickey. Part of the reason for the recent surge in barge manufacturing, ac- cording to Mr. Dickey, is the ever- growing list of commodities being moved by barge on the nation's 25,000-mile-long inland waterways system. "There are a number of different factors responsible for the boom- ing barge business," Mr. Dickey said. "For example, increased grain export quotas are boosting demand for barges to move large quantities of grain to "ocean ports. More barges are needed to transport in- creased quantities of coal to elec- tric power generating plants. And, the normal barge replacement mar- ket has been exceptionally strong since the beginning of 1971." Mr. Dickey said Dravo expects the heavy demand for barges and towboats to continue in 1973. Dravo entered the marine equip- ment business nearly 70 years ago and launched its first steel barge in 1915. Today, it is one of the top three barge builders in the country. Samson Develops New Braided Line For Taut Mooring A new braided line has been de- veloped by Samson Cordage Works, Boston, Mass., for application where a minimum of elastic and permanent elongation is required. Designated Samson VLS, the new line uses polyester fibers in a special 12-strand braid construction. Initially used for the Taut Mooring of Oceanographic equipment, Sam- son VLS is reported to have elastic elongation of less than 5 percent at 30 percent load. Other features in- clude freedom from torque, extreme flexibility, non-hockling, and easy splicing. Samson VLS braided line comes in a size range from J^-inch diameter to 1-inch diameter (3-inch circumference), and with approxi- mate average breaking strengths of up to 40,000 pounds. It is available in minimum quantities of 10,000 feet for a given diameter. Descriptive information and speci- fications are available by requesting Bulletin MI-1 from Samson Cordage Works, 470 Atlantic Avenue, Boston, Mass. 02210. Managerial Change At Mitsui OSK Lines S. Arii has been named to suc- ceed T.Wakasugi as New York chartering manager for Mitsui OSK Lines Ltd. Mr. Wakasugi will be transferred to the firm's Tokyo head office effective early this year.
