42 Maritime Reporter & Engineering News New Sound Dampening Coating Mascoat Products released its newest version of the Delta dB Sound Damping coating. The coating is reportedly capa- ble of sound damping of 12 dB in only a 60 mil (1.5mm) thickness. The water based coating can be applied by brush, roll or airless spray method rapidly and has no harmful VOC's. Delta dB comes in standard colors of white, light grey, grey and flat black. The product has passed testing to IMO A 653.16 and can be used under the interior finish coat rul- ing of all major class societies. World's Largest Radial Turbocharger Debuts MAN B&W recently introduced what it calls the world's largest radial tur- bocharger for two stroke engines and thermo efficiency systems. The TCR series is designed to set new standards for radial-flow turbochargers: high power density, low weight and a com- pact design. A total of six frame sizes cover four and two-stroke engines from 390 to 5,800 kW engine output per tur- bocharger. TCR22 is the largest frame size of the series. Test runs on a 6S35MC engine rated 4,440 kW/173 rpm showed efficiency over the entire load range, helping to lower fuel con- sumption as well as the exhaust gas tem- perature, which in turn relieves thermal stress on other engine components. HTiBS Receives INS Class C Approval The Hyundai-Transas intelligent Bridge System (HTiBS) from Hyundai Heavy Industries and Transas Ltd. recently became the first system to be type-approved as INS class C. Designed in full compliance with IEC1924 standard, it gained the certifi- cate from Det Norske Veritas. The sys- tem is desgined to provide the navigator with: an integration of navigational data, databases and ship's particulars; simul- taneous execution of application on one workstation; ability to connect/integrate with external hardware and software; close control of received data quality; and alarm management to support a safe level of situation awareness. RKI Offers Portable Gas Detector The Marine EAGLE from RKI Instruments, Inc. is designed to provide detection combinations in a portable gas monitor featuring gases like % LEL and volume of hydrocarbons, oxygen, as well as PPM levels of hydrogen sulfide and/or carbon monoxide. The EAGLE features include an infrared sensor for combustible gas monitoring in inerted tanks, dual hydrophobic filters, strong internal pump with low flow auto shut off and alarm, internal oil mist filters, ergonomic RFI/EMI/chemical/weather resistant enclosure, operating hours for over 30 hours on alkaline batteries, and a variety of accessories for specific applications. Software Monitors Underwater Noise Sound-Guard is a PC-based data acquisition system used to measure, monitor, and log the underwater sound levels from any vessel. It is useful for research vessels which need to maintain low underwater noise during sensitive scientific operations. It may also be used by vessels that need to monitor sound output while operating in sensi- tive ocean areas or around sensitive marine habitats. Sound-Guard is designed to be used with existing hull mounted hydrophones, but ships with- out such equipment can also use Sound- Guard by installing other transducers. The software was developed by Noise Control Engineering (NCE) for the University of Delaware's new research vessel, R/V HUGH R. SHARP with a grant from the Office of Naval Research (ONR). New McMurdo NAV-7 GMDSS NAVTEX McMurdo's NAV-7 is the new gener- ation GMDSS NAVTEX Receiver. Information is delivered on a six-in. screen. It offers simultaneous tri-chan- nel monitoring, meaning that a single list of Navtex messages can be viewed together. An automatic sorting feature allows a message to be viewed on screen and sorted by channel, station ID, message category or age. An index message list- ing page allows for quick searching and direct access to full message text. New Marine Selector Valve Parker Fluid Control Division now offers the Marine Selector Valve designed for electric remote tank selec- tion in applications with multiple diesel and/or gasoline fuel tanks. The Marine Selector Valve permits continuous engine function during tank switching, from the safety and convenience of the boat's control panel. The two-way, nor- mally closed valves, rated for fuel safe- ty shut off, features integral solenoids and a manual override in a one-piece construction. Applications for this valve include marine engines, generator sets and cross-over piping arrangements, as well as fuel balancing. The Marine Selector Valve is manu- factured with six ports for fuel return in diesel tanks and three ports for gasoline. Available in aluminum, the new valve has a flow capacity of 180 gph and fuel line connections of 0.5-in. Female NPT. DVD: Immersion Suit Training: It Could Save Your Life Immersion Suit Training: It Could Save Your Life, is the latest training aid from Maritime Training Services, and illustrates how Immersion Suits can be used to improve a seafarer's chances of survival in an emergency. Having an Immersion Suit for each person on board is not just good practice; SOLAS will soon require it. Immersion Suit Training: It Could Save Your Life, an 11 minute DVD from Maritime Training Services, takes a close look at the use and maintenance of these important life saving appliances. Filmed on the icy waters of Puget Sound, the program starts with a look at the dangers of hypothermia, the unseen killer, and how Immersion Suits can be used to improve a seafarer's chances of survival in an emergency. New Tank Cleaning Machine Alfa Laval launched a new single-nozzle tank cleaning machine, the Gunclean Toftejorg i65 S. It incorporates low-wear materials and advances in mechanical design, such as a hysterisis clutch. The hysterisis clutch is designed to be more reliable than tradition- al machines. Comprising a hys- terisis plate on one side and six supermagnets on the other, it creates an even magnetic field that does not require synchro- nization. The hysterisis clutch also allows design changes that protect against leakage and cross-contamination. G- Pass, the Alfa Laval software used in preparing shadow diagrams, lets Alfa Laval evaluate the proposed clean- ing solution, creating a three-dimension- al image of the tank and its corrugations, stringer platforms and other internal obstructions. This image can be viewed from any angle, revealing any "shad- ows" that are not directly hit by the cleaning jets. Products Anti-heeling Pump Allweiler AG manufacturers its ALLTRIMM anti-heeling propeller pump in seawater-resistant alu- minum bronze (CC333G). This inline propeller pump has reversible hydraulics and a uni- form pumping capacity. Three radial-shaft sealing rings contain an integrated leak sensor. The electric motor is constructed with standard parts from a German manufacturer and conveniently integrated into the pump lobe. As a result, the pump forgoes components required in conventional designs such as a valve controller, coupling, and gearbox. The pump is available in one and two-stage versions that deliver a flow rate up to 1,300 cu. m./hour and delivery heads up to 10 m (sin- gle-stage) or 20 m (two-stage).
