Papers Call For First Pan-American Conference Of Ocean Engineering The First Pan-American Con- ference of Ocean Engineering, which will be held in Mexico City, October 20-23, 1980, sponsored by the Pan-American Federation of Engineers Associations (UPADI), the Mexican Committee on Ocean Resources Engineering (COM- IRO), and others, has decided to extend the deadline for submit- tal of abstracts and papers, as follows: submittal of abstracts, May 4, 1980; communication of approval of abstracts, May 31, 1980; submittal of papers, July 31, 1980. The general theme will be "Par- ticipation of Engineers in Na- tional Decisions," and papers on the following general topics are requested: the future of ener- getics, necessary alternatives for development, importance for de- veloping countries, appropriate technological exchange, and inter- relation between Pan-American associations. Two-page abstracts should be submitted to Comite Organizador del Congreso Pan- americano de Ingenieria Oceanica, Apartado Postal 60-549, Mexico 18, D.F., Mexico.

MarAd Awards Contract For Sailing Ship Study The Maritime Administration has commissioned a study to de- termine whether wind-powered ships could compete effectively with conventionally powered mer- chant ships, Assistant Secretary of Commerce Samuel B. Nemirow announced recently. MarAd, an agency of the U.S. Department of Commerce, award- ed a $138,840 contract for the 12-month study to a team headed by former shipyard executive Lloyd Bergeson, president of Wind Ship Development Corpo- ration, Norwell, Mass. The group is to expand upon a preliminary study completed by the Univer- sity of Michigan in 1975. "The Michigan study concluded that a commercial sailing vessel was not then an economically feasible alternative for the Amer- ican merchant marine, but said the figures were close," Mr. Nem- irow said. "With the continued escalation in the price of fuel, we believe it is time for another look." He noted there are foreign- policy as well as economic reasons for reducing the nation's depend- ence upon foreign oil. "Because it is pollution free and constantly renewed, wind power is an ideal candidate," he added. The Bergeson group will ana- lyze ship characteristics, trade routes, and commodities to deter- mine market opportunities best suited for sailing ships of various sizes. It also will examine the overall economic potential of sail- ing ships in world trade. Modern wind-powered cargo ships most likely would empioy hybrid propulsion systems with auxiliary engines for use in calm seas, and to improve maneuver- ing capabilities in harbors and other restricted waterways. Aero- dynamically designed sails made from synthetic materials, coat- ings to protect the ship's hull and reduce friction, and modern com- munications equipment which pro- vides continuous updates on weather patterns are among other possible departures from the sail- ing technology of the 19th cen- tury. The Bergeson group was se- lected after evaluation of a total of six proposals submitted to Mar- Ad in response to an August 13, 1979, request for study ideas. Other members of the contract team are Frank MacLear, presi- dent of the naval architectural firm of MacLear and Harris, New York, N.Y.; Henry S. Marcus, associate professor of ocean en- gineering at the Massachusetts Institute of Technology; Dr. James H. Mays, an ocean engi- neering scientist of Providence, R.I.; A.P. Bates, consultant, Hing- ham, Mass.; Dr. Petrus A.M. Spierings, consultant, Boston, Mass.; and P.C. Anderson, presi- dent of Sail Freight, Interna- tional, North Kingstown, R.I. Three new tugs join the Bay-Houston family. Three new additions to the Bay-Houston fleet will be the Barbara H. Neuhaus, Laura Haden and MarkK. All attest to the dedica- tion of Bay-Houston to provide the best towing service available on the Gulf Coast. BAY HOUSTON TOWING CO.

Applied as a cold, thixotropic compound, it reacts to create a hard, super abrasion resistant synthetic metal which is so tough it is vir- tually impossible to machine! Outstanding resistance to chem- icals, thermal shock, impact and stress. A ton-and-a-half PSI ad- hesion and can even be applied underwater!

Ceramic Metal quickly rebuilt it, and also rebuilt the End Plates, Division Bars and Water Boxes. BELZONA MOLECULAR INCORPORATED 224 Seventh Street. Garden City.
