SNAME Annual Program (continued from page 11) Port Valdez. Tankers will then transport the oil to the various ports within the "Lower Forty- Eight." This paper presents the original real-time simulation anal- ysis of the TAPS tankers within Valdez Narrows, describes the be- havior of the man-controlled ship, and discusses simulation tech- niques. Paper No. 13—"Reliability and Safety of LNG Shipping: Lessons from Experience" by Bertrand De Frondeville. Synopsis—The LNG shipping ex- perience, available from almost 3,000 cargoes unloaded since 1964 in Europe, Japan, and the United States, is reviewed from the standpoint of reliability and safe- ty. The record of upstream (lique- faction, loading ports) and down- stream (receiving terminals) components of the LNG transfer system is summarized. Factors contributing to a successful safe- ty record and improving relia- bility are analyzed, and citizen participation encouraged. Paper No. 14 — "A Solution to the Series Production Manufac- ture of Aluminum LNG Spheres" by P. Takis Veliotis. Synopsis — This paper describes an advanced manufacturing con- cept for the quantity production of large spherical aluminum LNG cargo tanks for use in the LNG shipbuilding program at General Dynamics Quincy Shipbuilding Division. Extensive detail is giv- en on the series production man- ufacturing process, the use of au- tomated welding techniques and the testing, insulation and trans- portation of the spheres to the installing shipyard. Request Approval To Sell Fishing Vessels To Foreign Companies The Maritime Administration has received two applications for the approval of sale of fishing ves- sels to foreign companies and the transfer of the vessels' registries and flags to foreign countries. One vessel is the Caribe, a 900- gross-ton, purse-seiner type tuna boat, owned by Captain Steven Scott, Inc., San Diego, Calif. The application is for transfer to Caribe Fishing Co., N.V., a Neth- erlands Antilles company, and op- eration under Netherlands Antil- les registery and flag. The other vessel is the M/V Reefer Star, a 3,760-gross-ton tuna fleet mothership, owned by Star-Kist Foods, Inc., Terminal Island, Calif. The application is for transfer to' Star of the Pacific, S.A., a Panamanian corporation and wholly owned subsidiary of Star-Kist. The vessel would be operated under Panamanian reg- istry and flag. $320,000 Three-Party Award From MarAd For Propeller Research The Maritime Administration has entered into contracts with three parties to conduct a joint research program to assess the technical and economic merits of a hydrodynamically coupled, contra-rotating propeller system. The parties are Sun Shipbuilding & Dry Dock Co., Chester, Pa., Transmission Technology Com- pany, Fairfield, N.J., and the David Taylor Naval Research and Development Center, Carderock, Md. The benefits are expected to in- clude a significant improvement in propulsive efficiency that could save about 10 percent of the fuel consumed on a typical ship. This initial research, costing approxi- mately $320,000, will include the construction of a model hull and equipment for making detailed comparisons under simulated op- erating conditions between two contra-rotating propeller sets and a single propeller arrangement. All work will be directed toward the possible future full-scale in- stallation on a stretched Ponce de Leon-Class ship. W. A. Whitney Structural Fabricating/ Material Handling Systems for offshore platform fabrication have the flexibility t< Component parts and their functions are listed in Q Raw Stock Feed Rack — holds up to 40 beams which are sequenced by priority for utmost efficiency. ^^ Control Panel — for operating feed rack, conveyors, saw gaging, short drop unloader and storage area of beam transfer conveyor. ^^ Powered Conveyors — provide rapid forward and reverse movement of material. Q Cold Saw. operational sequence: ^^ Saw Gaging System — provides accurate linear measurement for cutting operation. ^^ Beam Unloader & Storage Rack — for removal of stub ends of cut-to-length beams. ^^ Beam Transfer — stores beams requiring punching. ^^ Control Console — moves beams onto infeed conveyors, operates all functions of the Beamline and removal of completed material. To Welding Painting Shipping Modern fabricating equipment coupled with an efficient material handling system can and will increase productivity. The modular design of the material handling equipment developed by W.A. Whitney Corp. can be adapted to either large or small fabricating plants. Costly building expansion programs are not necessary in most cases! N/C Multiple Punch X-Y-Z Automated Beam Lin< 12 Maritime Reporter/Engineering • News
