84Maritime Reporter & Engineering News TECHNICALPRODUCTSNew Integrated ShaftCoupling DesignVULKAN Couplings introduced acombination of the proven RATO DS coupling with a directly connected Com-posite shaft. The high radial stiffness and the comparably low axial and bending stiffness makes the RATO DS suitable to work not only as a torsional coupling but also as an integrated misalignment cou- pling when rigidly connected to an inter- mediate shaft. At the rear end of the intermediate shaft a torsionally stiff mis- alignment coupling creates the secondbending flexible pivot thus providing a double cardanic design. This new combi- nation consisting of RATO DS and inter- mediate shaft is called VULKAN Integrated Shaft Coupling (ISC). It was found that the angular deflection of theRATO DS causes ? even at high mis- alignment levels ? a rather low strain level compared to the torque load and thus a low power loss. Therefore no mis- alignment coupling is required betweenRATO DS and shaft. The intermediate shaft can be directly connected to theinner ring of the coupling whereby theRATO DS is radially not supported. The mass of the intermediate shaft islimited by the radial natural frequency of half the shaft and the inner part of theRATO DS. The design radial natural fre- quency is selected not to be less than 120% of design rpm. www.vulkan.com DataLog Fuel MonitoringFloScans new PC software, Data- Log, was designed to satisfy requestsfor recording fuelusage data for NOxemissions reportingand to simplify fuelinventory control. DataLog also provides the captain with valuable real-time fuel flow data to pinpoint the engine speed to improve fuel economy by 20% or more. And the individual supply and return fuel flow rates and temperatures keep track of the engines health and performance. Fuel flow parameters recorded and dis- played include: Net fuel flow rate; Net fuel usage total; Supply flow rate and temperature; and Return flow rate and temperature. www.floscan.com Multiflex: A ModularConcept for OSVsImtech Marine launched its modularMultiflex concept, which offers cus- tomers freedom of choice, selecting themost competitive, required technolo- gies via one point of contact, ImtechMarine, and create an optimum custommade total solution. The technology modules include Diesel-ElectricPropulsion, Power Distribution, Vessel Automation, Dynamic Positioning,Navigation & Communication, HVAC (Heating,Ventilation & Air Condition- ing), Fire Protection & Fire Fightingand Safety Systems. The worldwide service network of Imtech Marine pro- vides 24/7 maintenance and servicesupport throughout the ships life cycle. www.imtech.eu/marineoffshore New Tech for Submarine Wireless Battery Monitoring Raytheon Anschütz introduced a wireless battery monitoring technol-ogy. The core of the system is a new sensor that features a measurementconcept to provide high failure safety while contributing to cost sav- ings during installation and servic-ing. The Wireless Battery Monitoring System (WBMS) is thecentral measuring and evaluation system for main batteries aboardsubmarines. It continuously and di-rectly indicates the most important data on the condition of the batteries and conse-quently supplies decision aids for operational and tactical intents. The WBMS consists of a main control unit for monitoring and calculation, wireless cell sensorsand wireless transceivers to transfer the data from the battery cells to the control unit. The new wireless sensor measures voltage, acid temperature and acid level of every battery cell. Compared to conventional battery monitoring the monitoring of every battery cell raises failure safety, data availability and reliability of the whole system. www.raytheon-anschuetz.com HyperSizer v6 Collier Research released HyperSizer v6 struc-tural sizing and analysis software for reducing weight, maintaining strength, and improving the manufacturability of complex composite and metallic designs. Developed and proven at NASA, the software?the first ever commer- cialized by the agency?has a track record of 20 percent weight reduction in high-profile govern- ment and commercial aerospace projects. HyperSizer integrates with FEA solvers in a continuous, automated iterative loop, conducting trade studies and examining mil- lions of potential design candidates down to the ply, even element, level. The soft- ware ensures structural integrity through an extensive suite of failure analysis predictions that are validated to test data. The tool also enhances manufacturability by minimizing ply drops, identifying and controlling laminate transition drop/addboundaries, and defining best ply shapes and patterns. Hypersizer can be used from preliminary design to final analysis. Serving as the analysis hub and automating data transfer during both design and manufacturing cycles, HyperSizer integrates with FEA software, such as Nastran and Abaqus, and with composite CAD tools, such as CATIA and FiberSIM. HyperSizer ensures that design and analysis departments are kept current and working with the same design data. www.hypersizer.com PosiTector 6000 Coating Thickness GageDeFelsko offers the PosiTector 6000 coating thickness gage, which the manu-facturer claims is smarter, faster and more powerful. Both Standard and Ad- vanced models feature built-in memory, onscreen statistics, USB mass storage,and new Fast mode. Advanced models also include hi contrast reversible color LCD, Scan mode to store continuousreadings, onscreen help, real time graph-ing, picture prompting and more.Changes have been made to memory storage and downloading capabilities. PosiTector.net will allow users to upload stored measurements, generate detailedand customizable reports, and share yourresults with your colleagues via a secureinternet connection. www.defelsko.com Proline Promass 83X/84X Coriolis FlowmeterEndress+Hauser announced the ProlinePromass 83X/84X Coriolis flowmeter, the first large four-tube Coriolis flowme- ter. The 14-in. diameter flowmeter is for measuring the mass flow, density and temperature of oil, gas and other fluids inlarge pipes at rates up to 4,100 tons/hr with extreme accuracy and precision. The 83X model comes standard withfully traceable 0.1% flow accuracy, and optionally with a flow accuracy of 0.05%. The 84X is suitable for custody transfer applications, featuring MID(OIML R117) and PTB approvals. www.us.endress.com Converteam for UltraDeepwater DrillshipsConverteam was selected by Hyundai Heavy Industries (HHI) as designer and supplier of electrical systems for threenewbuild ultra-deepwater drillships for Noble Corp. The Hyundai Gusto P10000 designed drillships, rated foroperations in up to 12,000 ft. water depth, are under construction by HHIat its Ulsan facility in South Korea. The first vessel is due for delivery to Noble in early 2013 with the third due in early2014. Converteams responsibility is for a mission critical package of elec-trical works which includes major com- ponents of the electrical power generation, power distribution, propul- sion systems and drilling drive systems.
