ON THE COVER Bender Delivers Fourth Tuna Boat Bender Shipbuilding and Re- pair, Mobile, Ala., recently de- livered the 3,600-horsepower, 225- foot tuna boat "El Audaz," its fourth tuna purse seiner in a four-boat order. When the shipbuilder finished the outfitting, the El Audaz cast off with sister vessel the Cen- tauro Del Norte from Mobile for fishing in the Pacific. "This represents something of a milestone for us," explained president Tom Bender Jr. "We have successfully executed one of the most advanced designs for vessels in this size range. Com- pleting this fully molded hull with aluminum superstructure, together with their other sophis- ticated systems, represents an advancement of our proven ca- pabilities. And we did it not once, but four times. We thank our Mexican friends for award- ing us this contract and thus recognizing that we are not just another shipyard." The El Audaz was christened by Maria Elena Estrada Del Castro Y Castro, wife of the Di- rector of Coordination and Pro- motion for the Mexican Govern- ment organization, Conasopa. The steel-hull tuna boats are capable of carrying 1,200 tons of fish, 85,000 gallons of fuel, without fishwells, and approxi- mately 200,000 with fish wells, and 8,500 gallons of water at a swift 16 knots. The only part of the two ves- sels made of aluminum are the pilothouses which are reinforced for helicopter landings. Main propulsion power is pro- vided by a 20-cylinder EMD die- sel (Model 20-645-E7) which pro- duces 3,600 horsepower at 900 rpm. This power is transmitted to a Rice, four-blade, highly skewed propeller through a Falk gear box. Main engine controls are by Mathers of Seattle. Auxiliary power is provided by three Caterpillar D3408 diesel en- gines each developing 285 kw at 1,800 rpm. The main hydraulic power source is a Cat 3408 which develops 500 hp at 2,100 rpm's. Steering gear is hydraulic, a Wagner LAZ-16-35 furnished by W.E. Hough of Seattle. Four 100-hp Vilter compres- sors are used to power the am- monia refrigeration system and the bow thruster is Michigan' Jastram 49" prop model BU60, powered by a GM 12V71 diesel engine (400 hp at 2,100 rpm). The main hydraulic systems are furnished by Marco of Se- attle. They include the WS 454 Super Seiner II Seine Winch, 3020 Cork Line Winches, WO 332 Brailing Winch and B56A Power Block. Also supplied were miscellane- ous Gearmatic winches for vanging, topping, choking and strapping. Incorporated into the hydraulic system is a Slattery "Alaska Marine" deck crane on the forward deck and a Morris Whaley ring stripper. Naviga- tional aids include a Sperry 8T autopilot and a Mark 37 gyro- compass. Electronics, furnished by Hon- or Marine of San Diego and in- stalled by Sassman Electronics of Mobile, include two Furuno FR1011 radars, Whelen strobe light, Furuno FE-8130F echo- sounder, TAIYOADF, Furuno VHF/ADF, Navidyne ESZP, 3000 satellite navigation, Hull 2320A radiotelephone, Morrow SSB, Hull 922R/5, Raytheon VHF, R/T System, Honor Marine PA sys- tem, Furuno FAX143 facsimile recorder, Bear Cat 300 scanning receiver, Sea Temp seawater tem- perature monitor and Telcor wind- speed. A Krupp-Atlas sonar mod- el 950 has also been included in each electronic package. Other equipment includes pumps by Crane Deming, Buffalo Forge fans, Red Fox sewage treatment systems, Westphalia NASSCO Awarded Overhaul Contract For USS Hepburn Valued At $30.9 Million National Steel and Shipbuild- ing Company, San Diego, Calif., has been awarded a ยง30,945,342 cost-plus-fixed-fee contract for regular overhaul of USS Hepburn (FF-1055) with an option to have a regular overhaul on the USS Cook (FF-1083).

The vessel was constructed by Astilleros Espanoles S.A. (AESA) and recently completed sea trials successfully. The brochure contains a com- plete description of the new ves- sel including a series of drawings illustrating the manner in which different types of heavy cargo can be transported safely and efficiently. A complete descrip- tion of the new ship includes di- mensions, profile drawings, dead- weight scales, capacities and de- centrifuges, Quincy air compres- sors, alarm systems by Argus, Halon Fire Suppression system in engine rooms by Ansul, Cutler Hammer controllers, Waukesha stern bearings and seals, Hose McCann navigation light sys- tems, paint systems by Interna- tional Paints, Englehart chloro- pacs, Everpure chlorinators and Micros 11 IP watermakers. tails on equipment such as the main engines, communications equipment, cargo handling gear, lifting gear, four-point mooring systems, etc. The Sibig Venture can transport very heavy loads of up to 44,000 tons deadweight, at a 3-meter freeboard. The ves- sel is capable of handling large offshore drilling rigs, platform jackets, cranes, entire dredges and industrial plants. ITC-Holland has been well- known for years as a world leader in the heavy cargo transport field. The company has seven tugs of 15,000 IHP each in addition to its heavy lift vessels and is ac- tively engaged in conventional towing operations in addition to the heavy lift phase of the busi- ness.
