MarAd Opens Seminars On Extending Lakes Navigation Season A series of seminars to discuss lengthening the Great Lakes-St. Lawrence Seaway navigation sea- son was recently inaugurated by the Maritime Administration, U.S. Department of Commerce. Held in Washington, D.C., the meeting was attended by represen- tatives of the Great Lakes shipping industry and marine insurers, as well as other interested groups. Deputy Assistant Secretary of Commerce for Maritime Affairs Robert J. Blackwell opened the ses- sion, explaining the seminars' pur- pose as growing out of a study by the agency of Great Lakes marine insurance rates. "Through these meetings, we hope to provide industry with the fundamental information necessary for a realistic insurance appraisal of an extended season," he said. Highlighting the first session were presentations by Rear Adm. W.A. Jenkins, USCG, Commander of the Ninth (Great Lakes) Coast Guard District, and Richard D. Jaeschke, Vice President of Opera- tions of the U.S. Salvage Associa- tion. Admiral Jenkins outlined the Coast Guard's efforts to keep Great Lakes sealanes open during the 1970-71 winter season, while The new Limitorque XPM is the first electro-mechanical water- tight valve operator developed specifically for safe, dependable and economical cargo handling on tankers and barges. The new device not only meets U.S. Coast Guard safety standards, but is also watertight and structurally strong to withstand the force of angry seas. The first ship to be equipped with Limitorque XPM operators is the new 76,500-dwt Esso San Francisco, shown on sea trials, above. One man at a central con- trol station can operate all cargo- handling valves for 21 tanks, so that her full 650,440-bbl cargo can be loaded or unloaded in less than 18 hours. The basic design for the Limi- torque XPM represents a new refinement of the Limitorque SMB, already world-famous for dependability in propulsion-sys- tem service on more than 80% of automated U.S. merchant ships. The Esso San Francisco is the first of three new Limitorque- equipped sister ships to be built by Avondale Shipyards. Each will have approximately 100 Limitorque XPM valve opera- tors on deck, and up to 50 Limi- torque Model SMB operators in propulsion and steering systems. If you want the best in valve- operation automation, specify Limitorque. Write for engineer- ing and performance data, and complete catalog information. Limitorque Corporation, Dept.

LIMITORQUE VALVE CONTROLS Mr. Jaeschke discussed the types of casualties sustained by vessels transiting ice-clogged passages, their costs, and possible preven- tive measures. Future sessions of the group, which is formally known as the MarAd Great Lakes-Seaway Risk Management Study Group, are scheduled to be held periodically over the next two years in various cities. Topics to be discussed in future conferences, according to Mr. Blackwell, include weather condi- tions encountered during the win- ter of 1970-71, the economics of Great Lakes water transport, de- sign considerations for improved vessel performance in ice, the un- derwriters' view of Great Lakes vessel operations, and the activities of other Federal agencies working to lengthen the Lakes navigation season, particularly the St. Lawr- ence Seaway Development Corp. and the U.S. Army Corps of Engi- neers. Participants in the first session represented Hanna Mining Co.. Cleveland-Cliffs Iron Co., Inland Steel Co., Johnson & Higgins, Marsh & McLennan, and the American Institute of Marine Un- derwriters. Representatives of the Great Lakes Protective Associa- tion, Dow Chemical Co., and the Toledo-Lucas County Port Author- ity also attended. AMF Appoints Tritten General Manager Cuno Division Roy A.
