The new barge, Knappton CTC350 (shown above), is a self- unloading grain barge designed for service on the Columbia-Snake River system from Lewiston, Idaho, to Longview, Wash. It is owned by Knappton Towboat Co., Portland, who have placed it under contract to Coast Trading Co. Conventional hinged steel doors covering hatches have been replaced by two rolling aluminum alloy doors, each 100 feet long and 1 1 Vi feet wide. The doors unroll from opposite ends of the grain storage area, traveling on horizontal rollers. Each door is individually motor-operated from current supplied the barge by the assisting tug- boat. A backup manual open-close system can be operated in case of power failure or other emergency. Knappton Barge CTC350 is the 141st barge launched by Zidell at Portland since 1961 and the third grain barge built by Zidell for Knappton. Although it has the same storage capacity (3,300 tons) as the other two, Knappton CTC350 has a lower profile—-to gain greater ease in towing and maneuvering—as well as the "Magroroll" system. reversing, vertical) ; TSR (two speeds forward, one speed reverse) ; Vee Drives (to 600-hp 16- degree shaft angle) ; Custom Drives (turbine pro- pulsion, double input units), and Offshore Pro- pulsion (480, 660, 760 and 960 MGH-TP bi- directional thrust units).

Lloyd's To Represent Sperry During Manufacture Of Stabilizer Units In Japan Lloyd's Register Specification Services will rep- resent Sperry Marine Systems, Bracknell, Berk- shire (a division of Sperry Rand), as the techni- cal authority responsible for compliance with the engineering specifications during the manufacture of Sperry's Gyrofin ship stabilizers in Japan. Agreement between Lloyd's Register and Sperry was reached following Sperry Rand Corporation's decision to license Sperry Rand Far East Inc., Tokyo, to build the Sperry Gyrofin's machinery in Japan for sale to Japanese shipyards and ship- owners. The Gyrofin machinery for this modern folding- fin stabilizer is being built at Sasebo Heavy En- gineering Co (S.SK.) under subcontract from Sperry Rand Far East. Sasebo Heavy Engineer- ing will build the fin boxes and heavy machinery. Under the agreement reached with Sperry, the services provided by Lloyd's Register will include a review of quality control arrangements, the inspection of components during manufacture and the supervision of shop trials to the owners' and shipyards' standards of acceptance. Lloyd's Reg- ister Specification Services will represent Sperry through its 10 offices in Japan, including a sub- office at Sasebo which is permanently staffed by engineer surveyors.
