Following are the subcontrac- tors and their role in the Lock- heed study: Earl and Wright, and Morris Guralnick Associates, Inc., both San Francisco, Calif., naval architect firms, will perform con- ceptual design analysis; Hydro- nautics, Inc. of Silver Spring, Md., and naval architect consultant Prof. J. Randolph Paulling Jr. of the University of California, Berkeley, will establish design criteria and motion analysis; The Bechtel Corp., and T.Y.

OTEC is the concept of using ocean surface waters, continually warmed by the sun, to heat and vaporize a working fluid (such as ammonia) which in turn drives a turbine to generate (alternating current) electricity. The gas is then condensed with cold water from the ocean depths and recir- culated. Lockheed has studied OTEC since mid-1974, first under con- tract to the National Science Foundation and then ERDA, con- centrating on engineering and economics. The OTEC concept was first propounded by a French physicist, Jacques D'Arsonval, in 1881. Robert Lounsbery McAllister Brothers, Inc., the 113-year-old New York City-based marine transportation company, has announced the appointment of Robert Lounsbery to the post of chief operating officer. Mr. Lounsbery, a 47-year-old graduate of New York Univer- sity, with a B.S. degree in man- agement, was previously vice president in charge of operations of Navios Corporation, United Steel Corporation's maritime sub- sidiary. Prior to joining Navios, Mr. Lounsbery had worked in various posts with United Brands Company, serving as assistant vice president, transportation op- erations prior to leaving to join Navios. As chief operating officer, Mr. Lounsbery will have responsibil- ity for the New York-based op- erations and will gradually as- sume responsibility for all other operating subsidiaries and divi- sions, including the ports of Phil- adelphia, Pa., Norfolk, Va., and San Juan, Puerto Rico, as well as Tug and Barge Dry Docks, Inc., McAllister Brothers' shipyard in New York Harbor. The company currently operates approximately 100 tugboats and barges along the Eastern Seaboard and in the Caribbean Sea. Lockheed Wins Contract To Evaluate Ocean Platform Candidates Lockheed and its team of sub- contractors have won a contract to evaluate six platform candi- dates that would carry massive power equipment to generate elec- tricity from ocean water temper- ature differences. The research program is called Ocean Thermal Energy Conversion (OTEC). Work on the 11-month contract from the federal Energy Research and Development Administration (ERDA) was begun in late July, according to Roger D. Fuller, program director at Lockheed Missiles & Space Co., Sunnyvale, Calif. Lockheed is one of three prime contractors to help ERDA select the best platform for a 100-mil- lion-watt OTEC electrical power plant to be constructed by 1984 to demonstrate the concept. Plat- form candidates for the study in- clude ship shapes, circular barge, The LcTourncau Difference: More Lift. All Electric. All LeTourneau. Marathon LeTourneau-developed heavy lift cranes serve the offshore industry, marine construction and dockside opera- tions with proven superiority of more than seven million hours in all kinds of hostile environments. marathon When it comes to long-radius lifting capacity, no other manufacturer quite compares with LeTourneau.
