Outstanding (continued) Services of New Orleans after com- pleting extensive conversions. The vessels were lengthened 16 feet to accommodate new liquid mud tanks and chain lockers, mak- ing the new overall length 216 feet. Each vessel was fitted with a more efficient, 55-inch Bird-Johnson 35/3S/FP bow thruster that devel- ops 16,050 pounds of thrust. Fritz Culver supplied new releasable ca- ble stops. A GM Detroit Diesel 4V-71 en- gine was installed to drive the four Mission Viking liquid mud pumps. Each pump can transfer 850 barrels per hour. Bender also carried out routine drydocking and repairs for the two supply boats. Besides its well-known new-con- struction capabilities, the Mobile yard is a leading ship repair facility, with three floating drydocks capa- ble of lifting up to 18,000 tons.

A pair of Marco- built combination crabbers built in 1979, the 122-foot Columbia and the 123-foot American Beauty were modified extensively for their new fisheries roles. Work completed on the Columbia included a pair of new Marco WT266 MarTrawl winches and the IntelliTrawl computerized trawling system, fabrication of a stern ramp and 10-inch recessed roller, 8-foot- wide net flat, trawl door pockets, box-type stern gantry, net reels, and hydraulic stern ramp gates. Along with extensive hydraulic and electrical systems work and power supply changes, other equip- ment added included a Rapp net sound winch, Pullmaster haulback winch and two gilson winches, and an aft-facing console added to the pilothouse with controls for the en- tire trawl system. The Columbia's propeller was re- pitched, chafing guards added, and engine room and exteriors were painted. Harris Electric installed new electronics, including a Furuno FCT-1411 color radar coupled with the GD-2000 color plotter, Simrad ES-380 echo sounder, Simrad FA- 100 catch indicator and ET-102 sounder with FR-500 Trawleye sys- tem. In addition to having much of the same hull work performed, the American Beauty was fitted with two Rapp TWS-i220 trawl winches and the Autohaul system, Rapp new sound winch, two Gearmatic gilson winches and a Gearmatic inhaul winch. Owner-furnished electronics in- stalled in the American Beauty by Lunde Marine Electronics included a Simrad EQ echo sounder, FR-500 Trawleye system, and FA-100 catch indicator, as well as a Raytheon NWU-50 color video plotter and NOM-50 tape date recorder. SAN FRANCISCO Southwest Marine During 1985 Southwest Marine, Inc. of San Diego repowered three 725-passenger ferries owned by the Golden Gate Bridge, Highway and Transportation District of San Francisco, replacing the original three gas turbines in each vessel with two fuel-efficient Detroit Die- sel 16V-149TIB engines. During the break-in period of the first vessel to be repowered, the San Francisco, the Ferry Division found "dramatically improved perfor- mance" from the dipe.°l-powered boat, leading to savings i., commut- ing time as well as impressive dollar savings. These savings are being achieved despite a reduction in pro- pulsion power from 7,500 shp with 26 Maritime Reporter/Engineering News
