allow it to operate with minimal vibra- tion signature. Airborne noise emitted from the gas turbine genset is limited to 90 dBa by the sound attenuated enclo- sure around the gas turbine. Exhaust noise normally requires no silencing. Reliability/Maintainability A gas turbine that is readily available for service is crucial in all marine envi- ronments. GE's products are proven, in that the parent aircraft engines from which the LM gas turbines were devel- oped have more than 216 million reli- able operating hours on various aircraft. For instance, through more than 300 GE Component Improvement Program ini- tiatives, extensive reliability and main- tainability advancements have been made to the LM2500. This program includes the infusion of advanced mate- rials, coatings, improved bearings and electronic fuel control. A continuous improvement has been demonstrated. In fact, when the LM2500 was introduced almost 25 years ago, the incidence of engine removal was estimated at 5,000 hours. U.S. Navy data shows that the removal interval for earlier versions of the LM2500 exceeds 18,000 hours and the most recent versions exceed 23,000 hours. Circle 175 on Reader Service Card Cygnus Goes Beyond Basic Cygnus Instruments has revised its Cygnus 1 Basic Model, which accurate- ly measures ship's hulls, bulkheads, decks and tanks through coatings without including the coat- ing's thick- ness in the measure- ment displayed. The system also mea- sures on rough corroded surfaces with little preparation and requires no grind- ing. New features include operator selection of probe frequency for enhanced measuring, calibration by either known thickness or velocity of sound and automatic or manual "off switch." The model also displays sound velocity setting off the gauge; automatic low battery warning; and an innovative error checking facility for accurate mea- surements. Circle 98 on Reader Service Card McNeece Design Stresses Security Two of the cruise industry's most renowned organizations have joined forces to develop Securite One, which will lead to a safe and secure cruise ves- sel. Formulated by John McNeece, July, 2000 chairman of U.K.-based cruise ship designer McNeece and Brigadier, and Brian Parritt, chairman of cruise and ship security specialists International Maritime Security (IMS), the vessel holds the most innovative creativity in shipboard safety and onboard security. Preliminary developments of Securitie One came in response to such disaster as the 1985 hijacking of Italian liner Achille Lauro, as well as a terrorist attack on the Greek ferry City of Poros, which left nine dead and 46 wounded. To prevent further incidences such as these, IMO and other U.S. directives led a series of maritime security legislation. Leading this fight is Securite One — a 40,000-grt, 800-capacity high-speed cruise ship designed to meet all threats. Though not a passenger carrying war- ship, the vessel is designed to meet the needs of all travellers. Spirit Debuts On Canal Carnival Cruise Lines' 84,000-ton Carnival Spirit will launch its inaugural season with a 16-day Panama Canal cruise from Miami to Los Angeles in April 2001 — subsequent to a special three-day Pacific Coastal cruise from San Francisco. The line also plans to operate the ship in the fall on a pair of 12-day Hawaii sailings and a 14-day Panama Canal voyage from San Diego. control and communication cables.

You can take a large amount of bridge control and monitoring functions and shrink them down to 81* x 11 inch sheets of technology, solving the space problem associated with bridge design. It also lets you take advantage of an ABS, USCG approved data buss that eliminates the cable runs to the bridge while still controlling and monitoring all systems assigned. The process is as easy as faxing us an x 11 inch sheet of control and monitoring items and we will provide a return fax of a panel design which does it all in a fraction of the space, weight, cable and labor associated with the traditional method. Two wires to the panel shown does it all.
