Equitable Delivers Four Watertaxis For African Offshore Oil Operations Equitable Equipment Company, Inc., New Orleans, La., shipbuilder, has delivered the four new high-speed watertaxis shown above for work in West Africa's offshore oil fields. The vessels, 32-foot personnel launches, were built by Equitable for Suthercraft Ltd., Port Harcourt. They are each powered by a single General Motors 8V7IN diesel engine and have top speeds of 25 miles per hour. The new boats were shipped from New Orleans to Port Harcourt via cargoship. Equitable is a wholly owned subsidiary of Trinity Industries. The reason is Norriseal quality. Norriseal valves are extra rugged and dependable—built to outlast other valves and require less main- tenance. They provide positive shut-off time after time with 360° disc sealing and handle working pressures up to 200 psi. Norriseal design insures long, leakproof operation. O-ring shaft seals, separate from the seat, prevent leakage from the valve bore, lock in lubrication and make replacement of both the seals and the seat easier, faster and lower in cost. Replaceable body O-rings provide end seals and eliminate the need for flange gaskets. Norriseal offers variety as well as quality. We make valves in sizes from 2" to 28" with manual or automated operators. We offer a variety of body and disc metals, including bronze and a large selection of elastomers.

Metropolitan SNAME Hears G.E. Authors —Nominates Officers For 1973-74 Season Pictured at the New York Metropolitan Section meeting, left to right: I. Hilary Rolih, chairman, papers committee; Robert D. Markhoff, General Eleotric Company; Nicola F. Pergola, executive committee; B. Siegel, John W. Mann and M.A. Prohl, authors, and Charles W. Wilson, chairman of the Section. The New York Metropolitan Section of The Society of Naval Architects and Marine Engineers met on March 13 at The New York Times Building, 229 West 43rd Street, in New York City. After a social hour and buffet in the Executive Dining Room, the technical session was held in the WQXR Auditorium. The paper presented was "Improved Turbine Operation by Drainage of Steam Systems and Monitoring of Vibra- tion," by J.W. Mann, M.A. Prohl and B. Siegel, all with the General Electric Company. This paper reviews recent opera- tional problems caused by water induction into propulsion turbines and the resulting heavy vibration. The phenomenon is described as an orbiting vibration of the turbine shaft. Analysis shows the condi- tions required to produce this re- sult. The steam system is discussed with a view to reducing the op- portunities for water induction and specific recommendations are made for improved drainage. A newly de- veloped vibration monitoring sys- tem is described which can be used to reduce turbine speed when very large vibration levels occur. Also during the meeting, chair- man of the nominating committee E.A. Catlin announced the nomina- tion of the following officers for the 1973-74 season : Donald Carpen- ter, chairman; Thomas J. Sartor Jr., vice chairman, and Robert P. Fulton, secretary-treasurer. I. Hil- ary Rolih and Nicola F. Pergola were nominated to the executive committee for a 'two-year period.
