ZENTECH ZODIAC HURRICANE RESCUE CRAFT ( Partial listing of exhibitors due to space limitations ) Boelwerf Uses Foran System To Design New Chemical Tanker Boelwerf S.A., the largest Bel- gian shipbuilder, recently signed a license agreement to use the Span- ish CAD/CAM ship design and pro- duction system, Foran. The ship- yard has already used the system to design a chemical tanker. Foran was developed by the Span- ish naval architects Senermar SA of Madrid, and is already being used in over 100 shipyards in 19 countries. Boelwerf s license agreement al- lows the yard to use all of Foran's subsystems: basic design, machin- ery and outfitting design, drafting, steel production, and machinery and outfitting production.

This brings the UK into line with the stated policies of the Swedish, Dan- ish and Dutch authorities who have also committed themselves to the Decca Navigator System until at least the year 2000. Only Norway and Ireland have yet to make their positions clear regarding their re- tention of the system. The new agreement ensures that the estimated 150,000 mariners of all categories who use the Decca Navigator System can now be as- sured of the continuous availability of this proven navigational aid. Service Engineering Co. Awarded $5.5 Million Navy Repair Contract The U.S. Navy recently awarded a $5,474,915 contract to Service Engineering Co. for repairs and alterations to the aircraft carrier USS Abraham Lincoln (CVN-72). The five-month selected restricted availability was awarded by the Su- April, 1992 pervisor of Shipbuilding, Conver- sion & Repair, San Francisco, Ca. Michael McNally Named Director Of Sales And Distribution At MMS Marine Management Systems (MMS), Inc., Stamford, Conn., re- cently announced the appointment of Michael P. McNally to the new position of director of sales and dis- tribution. Serving in this position, Mr. McNally will be responsible for di- rect sales planning and strategy for MMS, including the management of MMS' sales division. The sales division's mission is to promote MMS products to new customers as well as develop new channels of distribu- tion for the company. MMS is one of the leaders in in- ternational distribution in the ma- rine software industry, and cur- rently has installed close to 500 ac- tive systems worldwide, operating at over 250 shipboard and shoreside locations.

(604I 879-2974 • FAX (604) 879-6588 LO-REZ manufactures both the conventional un- tuned viscous dampers and its new patented mechanically-tuned viscous dampers. Extensive research has shown that the single and compound tuning methods, as developed by LO-REZ, reduce resonant amplitudes by some 40% and 60%, res- pectively, of the untuned values. Aluminum alloy ribbed housings of robust design provide cooler operation with less variance be- tween cold and hot performance. Dampers are bolted construction and are serviceable with facto- ry rebuild program. LO-REZ forced-damped com- puter program handles very large and complex power trains and provides for optimization of damper size and characteristics. Standard damper sizes are available as well as custom-engineered models. Designed & Manufactured by LO-REZ VIBRATION CONTROL LTD. LO-REZ manufactures a broad line of sturdy steel-spring vib- ration isolators. The BR series isolators (shown here) with their ample thrust capacity and rubber-cushioned, adjust- able stops (to limit excess ver- tical excursion) are widely used for marine auxiliary, other mobile and seismic applications. No external chocks are required. BR-T series isolators have spe- cial spring-loaded thrust • housings to carry the full propellor thrust effects, the full engine torque, and still provide excellent isolation. They are ideal isolation supports, also, for machinery rafts in ships. With the growing demand for acoustical and vibration attenuation treatment in ships, the isolation of main propulsion engines is fast becoming a necessity rather than a luxury. LO-REZ has many years of experience in analyzing the dynamics of soft-mounted propulsion engines, and has the products to provide integrated iso- lation systems which include two-directional thrust-type RT flexible couplings for the gear output shaft. STEEL-SPRING VIBRATION ISOLATORS BR4-LS LO-REZ helical steel-spring couplings, with their low, constant and accurately-controlled torsional stiffness factors, provide excellent torsional characteristics for geared marine reciprocating propulsion systems, engine and reciprocating compressor drives of many vari- eties, locomotive drives, etc. LO-REZ was one of the first coupling manu- facturers, 40 years ago, to recognize the im- portance of torsionally-soft couplings in power transmission systems, particularly in reciprocating, variable speed systems and those involving gearing.
