Initial Ship Design And Cost Prepared In Two Days By NKK With New Computer System Technician at Nippon Kokan monitors operation of com-puter-controlled equipment automatically preparing hull form line drawings for ship designs and cost estimates. A unique computer system for preparing initial ship designs and cost estimates within two days rather than the conventional period of one month has been introduced by Nippon Kokan K.K., Japan's only integrated ship-builder-steelmaker. Computers have previously been used on a piecemeal basis in initial ship design work but the NKK-developed system is the first to com-bine these functions in an integrated operation according to Satoru Suzuki, the company's New York general manager. The new system also improves the accuracy of preliminary designing and enables NKK to rapidly formulate revisions to original speci-fications. Upon receipt, owner specifications are ap-plied to the characteristics of a standard type vessel which have been previously fed into the computer, an IBM 360/75. The computer then calculates various data for the new design, in-cluding draft, trim, stability, displacement, deadweight, and longitudinal strength factors such as bending moment and shearing force. Following this procedure, several initial de-signs are prepared by Numericon and Panac units, computer controlled equipment made by Muto Kogyo Co. Ltd. and Essi Kinzmatic. Each design includes slight alterations of con-figuration. The system enables NKK to present multiple initial designs to owners with detailed explanations, backed by computer-prepared statistics and recommendations for optimum design. After the initial design is selected, complete plans are drafted by each section of NKK's basic ship design department. Alaska Ferry Lengthening Awarded To Bethlehem Steel Capt. H. J. Lockert, director, Division of Marine Transportation for the State of Alaska, has announced that Commissioner Harold D. Strandberg of the Department of Public Works has awarded a $1.9-million contract to Bethlehem Steel Company, San Francisco, for the lengthening of the Alaska ferry MV Tus-tumena, which currently serves the south central Alaska ports of Seward, Cordova, Homer, Valdez, Seldovia and Kodiak Island areas. Philip F. Spaulding and Associates, Inc., Seattle naval architects, who designed the original vessel and prepared this modification, states a 56-foot midsection is to be added to the vessel which will increase the overall length to 296 feet. This increased length will provide 14 additional spaces for passenger cars, or space for 9 more truck trailers. Staterooms for 16 passengers and 4 crew have also been added. This modification also provides for the installation of a Pacific Sea Leveler Mark X Retractable Fin Stabilizer System which will give comfortable travel in some of the world's most active seas. A 400-hp KaMeWa bow thruster is being installed to assist in docking. Two new 450-kw Waukesha ship service gen-erators are being installed to handle the increased electrical demand created by the jumboizing. Additional ship stores, reefer spaces, and crew's laundry facilities have also-been added. The vessel modifications are scheduled for completion before next summer's season be-gins. CHECKED YOUR BENDING RECENTLY? WALLACE S-M* SERIES HYDRAULIC BENDING MACHINES NEW FLOATING DRYDOCK put into operation by Mar-tinolich Shipbuilding Corporation, Tacoma, Wash. The 1,250-ton lifting-capacity dock is provided with four centering posts controlled from the control tower, enabl-ing the dockmaster to center the vessel quickly. The bilge blocks are attached to the centering posts and are cranked in from the vessel instead of the wingwall. The drydock is new in every respect and has been certificated by Philip F. Spaulding & Associates, Inc., of Seattle. For . . . Pipe ? Tube ? Angles ? How abo(Jt Channels ? Structural Shapes "STACKED" Dies? They are easy to operate. Only two levers to use? one to do the bending and reversing?the other oper-ates the mandrel?in or out! The mandrel unit is optional. These are low first-cost medium-production bend-ers. In five (5) sizes from 2" standard pipe capacity to 8" standard pipe capacity. Want to reduce set-uptime? Use ?"STACKED" dies. Here's a typical combination for bending ? ?W or VA" pipe without any changes. Other combinations avail-able. This Wallace 464 Series Roll-ing Machine is making tight coils in ONE pass through the machine. The tube is "Haynes"® alloy No. 25. Work L being done in the Materials b> "*ems Division of Union Carbide "orporation. Just a couple of benders we make. For a catalog on our complete line of Rotary - Ram - Roll Benders please write.
