New England Section Discusses Paper On Floating Nuclear Plants A large gathering of members and guests of the New England Section of The Society of Naval Architects and Marine Engineers met on March 16 to hear Clinton Dotson present his paper entitled "Some Design Aspects of Floating Nuclear Plants." Mr. Dotson is the naval architect for Offshore Power Systems, a joint venture of West- inghouse and Tenneco Corpora- tions for the design and manufac- ture of nuclear power plants for offshore siting. The concept described by Mr. Dotson utilizes a floating platform 400 feet long, 377.5 feet wide, and 40 feet deep, with a 'total plant dis- placement of 150,000 short tons. The platform supports a totally in- tegrated nuclear power station pro- ducing a net output of 1,150 MWe. The plant is designed to stay afloat for its lifetime, and remains moor- ed in the basin formed by a break- water constructed at the site. A lively discussion period follow- ed the formal presentation. Keat- inge Keays, Section chairman, served as moderator. Questions ad- dressed the areas of safety, ecology, breakwater construction, trade-offs between sunk and floating plat- forms, crew size, and 'transport of the crew back and forth to the sta- tion. Copies of the paper are available at $2 each from the Section Editor, Robert W. Baseler, New England Section, SNA ME, General Dynam- ics Corporation, Quincy, Mass. 02169. Jacuzzi Advances Jack Seastrom To Service Manager Omega is the first low-cost, worldwide navigation system for commercial shipping. With the Mackay Marine Omega Automatic Receiver Type 200, you will have accurate position 24 hours a day. It automatically tracks all stations being received. Synchronization is automatic, with a manual back-up system. The Type 200 is the only receiver which gives visual identification of transmitter stations for positive synchronization. This is important when the audio signal is not clearly distinguishable. Additional benefits include plug-in modules for ease of maintenance, a built-in ship test system for rapid check-out, and the reliability of all solid-state design. The most up-to-date Automatic Direction Finder, Type 4005A, permits bearings to be taken in less than 2 seconds, and positional fixes determined in a minute or less, with accuracy comparable to Loran over large distances. It is an excellent method of primary navigation, or may be used as a check on Loran or other methods. No opera- Omega Receiver Type 200 tion skills and training are necessary. The navigator clearly sets station frequency on the digital selector, and within 2 seconds a line of position is displayed on the large indicator. Advanced solid-state design permits quick servicing with most components mounted on plug-in circuit boards. All panel markings are back • lighted and a dimmer control is provided for setting light in- tensity to desired level. The di- rection finder is available with trunnion or rack mounting and can be secured to virtually any vertical or horizontal surface.

Mr. Seastrom's advancement to this new position is part of Jacuz- zi's current expansion program of providing more extensive service facilities and technical assistance to serve the rapidly growing mar- ket for its products. Jacuzzi is the only major manu- facturer of marine jet systems with nationwide parts and service facili- ties. The company makes an exten- sive line of "JacuzziJet" jet propul- sion systems in 12-inch to 36-inch stock sizes, and larger units to cus- tomers' specifications. Midland-Ross Corp. Introduces Tami-Lift Mobile Straddle Crane A Tami-Lift mobile straddle crane for handling containers has been in- troduced by the RPC Division of Midland-Ross Corporation. The unit, which has a lifting ca- pacity of 95,000 pounds, is equipped with a Universal spreader for han- dling 20-foot containers. The Tami- Lift is capable of stacking containers three-high. The division is the largest supplier of container-lifting spreaders in the marine industry. The diesel-powered crane's hoist, propulsion, and steering units are all hydraulically operated. A 90-degree steering capability permits easy ma- neuverability throughout the terminal. Because of the low initial cost, the Tami-Lift gives the low-volume con- tainer terminal or port an economical mobile crane, and it can be used as an inexpensive backup crane in high- volume container terminals.
