Circle 5 on Reader Service Card "HYN" Class Flux Cored Wire for HSLA-65 Steel Hobart Brothers has released the first military approved "HYN" classification flux cored wire for HSLA-65 grade steel (a new high strength, low alloy steel used to construct U.S. Naval ship hulls). Specially formulated to provide high strength welds on critical applications, the new Tri-Mark TM-71 HYN gas- shielded flux cored wire exceeds the extremely stringent welding standards established by the U.S. Navy. Circle 6 on Reader Service Card SBS Fire Protection System Kidde Fire Systems offer the new SBS Fire Protection System for marine applica- tions. Developed for use in small to medium sized vessels, the SBS Fire Protection System is designed to offer high-per- formance, clean agent fire suppression with optimized fire detection, fire sup- pression agent distribution and cylinder placement. It also features a patent- pending thermobulb heat detector, developed to react to the elevated tem- perature associated with machinery space fire. The SBS System is suitable for both gas and diesel powered vessels and is offered in two basic configura- tions: the Sentinel and the Sentinel PRO, both customizable for specific applica- tions. Circle 7 on Reader Service Card Hellbeater Fire Pump The "Hellbeater" diesel driven marine fire pump and moni- tor sets — portable equip- ment as used by the U.S. Navy and marine salvage companies — and stocks of the Pyrocool firefighting agent are available to municipal and port authority fire departments. The Hellbeater pumps and stocks of Pyrocool are ready for deployment aboard tugs, workboats and vessels of opportunity at the time of an incident, effectively converting the boats into NFPA Class A fireboat equivalents. Maritime Solutions is the U.S. supplier. Circle 8 on Reader Service Card Pulsating/Jetting Valve CAT PUMPS introduced the MAG-JET Valve for jetting. The MAG-JET uses a SS magnetic valve and a strong corrosion resistant magnet to hold one inlet valve open, creating a strong pulse-jetting action to power noz- zles through the toughest clogs. Circle 9 on Reader Service Card Gas Freeing Fans Alfa Laval introduced a new range of gas freeing fans for all vessel types. Light and portable, the fans are designed to pro- vide user-friendly, efficient and safe ven- tilation and complement the company's tank equipment portfolio. Three differ- ent models cover virtually all applica- tions, tanks and cargo types. The deep penetration fans are designed to provide top performance, directing the airflow to the tank bottom. This reduces the risk of vapor pockets accumulating within the tank. Time spent on gas free- ing operations is significantly reduced, thanks to high performance fans with deep penetration. Shorter operation time minimizes water consumption and as a result reduces energy consumption as well. Circle 10 on Reader Service Card New Wind-Heeling Method A general method for computing wind heeling moments based on the gemetri- cal model of the ship has been developed by Creative Systems, Inc. and is now available in a beta-test version. Called the Band method by its developer, it stands between the classical lateral plane projections and the more sophisticated panel-based wind drag approach. The Band method is still based on laterally- projected areas, but it automatically accounts for shielding between overlap- ping geometrical elements. It also applies to wind approaching from any direction, a capability important when analyzing the stability of mobile drilling units and other floating structures where ordinary transverse stability is not the major concern. The net result of the modeling efficiency and the run-time efficiency is a very substantial conven- ience which should prove beneficial, especially in preliminary design.
