SNAME Philadelphia Section Holds Joint Meeting With ASNE Shown at the joint meeting, left to right: J.M. Bollinger, discusser; W.G. Neal Jr., chairman, SNAME Philadelphia Section; E.D. Schaefer and D.C. Garber, authors; M.A. Morris and A.C. Brown, executive committee, Philadelphia Section; Hector T. MeVey, secretary-treasurer, and T.J. Kavanagh, vice chairman. The Philadelphia Section of The Society of Naval Architects and Marine Engineers held a joint meeting with the members of the Amer- ican Society of Naval Engineers on April 13 at the Engineers Club of Philadelphia. Ap- proximately 65 members and guests attended the meeting, which was preceded by cocktails and dinner. ASNE member Daniel C. Garber of Sun Shipbuilding and Dry Dock Co. presented a paper covering an oily water separator system for shipboard use. The oily water separator (patent applied for) system is designed to process any oil-water mixture regardless of quality or quantity of oil content. Various components comprising the system act essentially to effect the complete separation of oil and water, using only physical processes and without any recourse to heat or chemicals. The system yields clean water 'hav- ing less than 10 PPM oil content. A pilot plant has been installed on board the 80,000-ton tanker S/S America Sun. The sys- tem has operated successfully on three ballast trips between Marcus Hook, Pa., and Port Ar- thur, Texas. R. McFadden, chief of the machinery depart- ment at the J.J. Henry Co., Inc., Moorestown, N.J., office, discussed the paper presented by Mr. Garber. The subject of the evening's second paper was "Application of Finite Element Analysis CARRINGTON SLIPWAYS Pty.

Mr. Schaefer described the use of matrix techniques based on finite element representa- tion and its application in the design and anal- ysis of ship structures. The finite element analysis method can pro- vide an economical, rapid and reliable means of predicting the stresses • and deflections of various 'types and sizes of ships. The matrix method provides a greater knowl- edge of how the ship structure behaves; pro- vides an accurate picture of displacement and stresses for each element in the structure; when used in conjunction with a digital com- puter, can rapidly verify the overall length of the ship structure, and reduces overall vessel construction costs and provides a means for insuring greater safety and reliability in the design of all types of ship structures. J.M. Ballinger, manager of research and de- velopment at Sun Shipbuilding and Dry Dock Co., discussed the paper presented by Mr. Schaefer. The meeting was coordinated by A.C. Brown, general manager of the J.J. Henry office at Moorestown. Both authors were presented with a certi- ficate of appreciation by Walter G. Neal Jr., chairman of the Philadelphia Section. GE Names Bonner To Head Marine And Industrial Dept. Orville R. (Bud) Bonner has been named general manager of GE's Marine and Industrial Department, according to an announcement by Gerhard Neumann, vice president and group executive of the Aircraft Engine Group. Mr. Bonner's headquarters will be in Evendale, Ohio. Mr. Bonner succeeds Samuel J. Levine, who has been appointed manager of operational ef- fectiveness for the Aircraft Engine Group, re- porting to Mr. Neumann. In his new position, Mr. Bonner will be re- sponsible for all design development, market- ing, production and customer service for ma- rine and industrial applications of GE-buil't aircraft gas turbines. He has 20 years' associ- ation with the aircraft engine business. His last position was general manager of the Avia- tion Service Department. 305 Riverdale Avenue, Port Chester, New York 10573 Maritime Reporter/Engineering News
