Tracor Marine Awarded $8-Million Contract By Rockwell International Tracor Marine, Inc., a Fort Lauderdale, Fla., subsidiary of Tracor, Inc., has been awarded a fixed-price contract from Rock- well International to operate the vessel Ocean Energy Converter in support of the Department of En- ergy's Ocean Thermal Energv Conversion (OTEC) Program. The contract is for two years with an approximate value of $8 million, with operations for two addition- al years. Moored off the island of Hawaii in 4,000 feet of water, the 525- foot vessel and its 2,200-foot-long gimbaled pipe bundle will be the platform from which several pro- totype megawatt heat exchangers will be tested.

MARITIME REPORTER/Engineering News 107 East 31st Street New York, N.Y. 10016 (212) 689-3266 OTEC is a promising alternate energy scheme presently being developed by the Department of Energy. The basic principle is to use the temperature difference between the warm surface waters and the cold deep waters avail- able in tropical latitudes to evap- orate and condense a working fluid such as ammonia. The en- ergy of expansion derived during the evaporation process can be used to drive a turbine for elec- trical power generation. Although the vessel will be moored, all systems will be opera- tional as the ship's special thrust- ers will be used to counteract the force of variable currents at the site. Approximately 50 crew mem- bers and management and sup- port personnel will be involved in operating and monitoring the vessel and various onboard test systems. Tracor Marine has played a key role in pioneering efforts to har- ness the vast wealth of the oceans for many years. Taking over the operation of the largest OTEC test platform in this new techno- logical area represents another of the firm's involvement in such ef- forts. Tracor, Inc. is an interna- tional technological products and services company headquartered in Austin, Texas. IBM Awarded $3.6-Million Navy Contract For Sonar System Components International Business Ma- chines Corporation, FSD, Manas- sas, Va., has been awarded a $3,628,375 modification to a pre- viously awarded contract for long lead materials for the AN/BQQ-6 sonar system. Work will be per- formed in Manassas, Va., and Owego, N.Y. The Naval Sea Sys- tems Command was the contract- ing activity. (N00024-78-C-6189) At joint meeting of ASNE Golden Gate Section and SNAME Northern California Section (L to R): Henry Olson, papers chairman, SNAME; Peter A. Fisher, author; Grant C. Johnson, author; Thomas B. Cole, Section chairman, SNAME; and Capt. Art Wardwell, USN, Section chairman, ASNE. Joint SNAME/ASNE Meeting Hears Report On SPC Coating The annual Joint Meeting of The Society of Naval Architects and Marine Engineers, Northern California Section, and the Amer- ican Society of Naval Engineers, Golden Gate Section, was held re- cently at the Fleet Admiral Nim- itz Club, Treasure Island Naval Station, Calif. A paper titled, "Evaluation of SPC Underwater Coating on a Modern Container- ship," was presented by Peter A. Fisher of Matson Navigation Company, and Grant C. Johnson of International Paint Company (Calif.), Inc. Hull surface roughness, bio- logical fouling, effect of rough- ness on propulsion power, and characteristics of self polishing copolymer (SPC) coatings that help prevent fouling and limit in- crease of roughness over the life of the ship, were discussed in the first part of the paper. The second part dealt with a trial application of an SPC coat- ing, supplied by the International Paint Company, on the Matson Navigation containership Maui. The performance of this ship was compared over a two-year period with performance of the Manu- lani, a very similar containership operated on the same route but coated with a conventional anti- fouling system. The paper con- cluded that, in spite of its much higher cost, the SPC system ap- peared cost effective because per- formance degradation (in terms of fuel consumption increase as a function of time since last dry- docking) was much less with the SPC system than with the con- ventional antifouling system. 20 Maritime Reporter/Engineering News
