MarAd Appoints Pierre Becker To Inland Waterways Post Andrew E. Gibson, Assistant Secretary of Commerce for Maritime Affairs, has approved the establishment of a new position in MarAd's Central Region. The position, Special Assis- tant for Inland Waterways, demonstrates Mar- Ad's recognition of the important role the waterways will play in foreign commerce, as a result of new ocean shipping concepts such as 'barge-carrying vessels and oceangoing tug and barge systems. MarAd's Central Region Director Frank X. McNerney announced the appointment of Pi- erre R. Becker to the new post, with headquar- ters in New Orleans. Mr. McNerney further stated that it will be Mr. Becker's responsi- bility to work closely with inland and inter- coastal tug and barge, as well as LASH and SEABEE operators with the object of maxi- mum facilitation of foreign commerce cargo movements. A graduate of the U.S. Merchant Marine Academy, class of 1942, Mr. Becker has been active in the maritime field since graduation. He began his career by sailing in various engi- neering capacities with the United States Lines and was appointed chief engineer of a 20,000- ton naval transport at the age of 23. As an active Naval Reservist with the rank of cap- tain, Mr. Becker served in World War II and the Korean Conflict and has experienced eight years as commanding officer of various units, including destroyers. Mr. Becker's recent position as Chief, Divi- sion of Manpower Development, Maritime Ad- ministration, included assisting the inland water industry leaders in developing and ad- ministering the National River Academy in Helena, Ark. Reduction In Laker Freeboard Indicated At Close Of SNAME Symposium Held In Canada At the concluding session of the recent Soci- ety of Naval Architects and Marine Engineers Symposium on Great Lakes Ore Carriers, Dr. Pierre Camu, the administrator of the Canadi- an Marine Transportation Administration and president of the St. Lawrence Seaway, advised that "The most recent studies have indicated that a substantial reduction in the winter sea- sonal freeboard can begin this year. The pro- posed reduction should permit not all, but some existing large carriers presently entitled to the reduced freeboard, to carry approxi- mately another extra thousand tons of cargo during the winter season ('between November 1 to April 15)." These timely remarks represent the culmina- tion of many years of study of hull stresses in bulk carriers in the Great Lakes and Gulf of St. Lawrence wave environment. These studies have been coordinated by The Society of Naval Architects and Marine Engineers in coopera- tion with U.S. and Canadian Great Lakes regu- latory, governmental and other organizations to assist the Load Lines Joint Technical Com- mittee in the review and updating of load lines for Lakers. Research 'began with model studies designed to predict wave forces and resulting stresses in full-size ships. Comparison was made between the model and the 730-foot Edward L. Ryer- son, on which elaborate measurements of hull stresses and deflection were made. Thus, for four years simultaneously wave measurements were recorded and then matched to the ship's actual response. Technical papers presented at this Symposium summarized this on-going program and stimulated illuminating discus- sion which will be of value in 'blending this research into meaningful regulations. From Dr. Camu's remarks, it is obvious that this re- search has already made a significant contribu- tion to the shippers on the Great Lakes; con- tinuing studies, including measurements to be made on the new 1,000-foot bulk carrier Stew- art J. Cort, and comparison with model tests of 730-foot and 1,000-foot ships, could possibily mean further updating of load line standards. Dr. Camu expressed a continuing interest on the part of the Ministry of Transport in re- search that may ultimately result in regula- tions such that "lake vessels, normally laid up from the latter part of December to the begin- ning of April, like most of us, will work on a 12-month year." Extension of the St. Lawrence Seaway operating season to Christmas was also cited as an abjective, according to Dr. Camu. He further noted that his staff would review the papers presented at this SNAME Symposium from an economic viewpoint as part of a continuing effort to increase the pro- ductivity of Great Lakes ships. The Symposium, held July 21-23 in tihe Cha- teau Laurier, Ottawa, represented the com- bined efforts of over 14 industry organizations, government agencies, academic institutions, and regulatory bodies from both Canada and the United States. Proceedings of the Symposium, both papers and discussion, will be available from The Society of Naval Architects and Ma- rine Engineers, New York, N.Y., as Bulletin S-2 "Hull Stresses in Bulk Carriers in the Great Lakes and Gulf of St. Lawrence Wave Environment." The data obtained from the four years of operating this research program is contained in SNAME Bulletin 2-17 "Wave Climate Study, Great Lakes and Gulf of St. Lawrence," and Bulletin 2-18 "Seaway Stresses Observed Aboard the Great Lakes Bulk Ore Carrier Edward L. Ryerson (1965-1968)."
