Sea Trophy is designed to ensure fast, easy and well controlled solution for the removal of (fuel-) oil which will limit, or even eliminate any or all economic and environmental damages, not to mention the possible depredation of company image. According to the manufacturer, Sea Trophy can remove oil at a rate of 70 cu. m./hr at 100cS. This hydraulically driven pump can be used for both light and heavy oil. www.vanheckgroup.com [email protected] System for GulfMark PSV?s Thoma-Sea Marine Constructors award-ed Robichaux Automation and Control, Incorporated (RAACI) a single source vendor contract to design and supply a complete Diesel Electric Propulsion sys-tem to outÞ t two GulfMark Offshore 280 Class Deepwater DP-2 PSVs. This is the Þ rst opportunity for RAACI to team with Thoma-Sea and GulfMark Offshore. The RAACI provided Power Manage-ment System will coordinate and control the interaction of the RAACI propulsion system and the RAACI electrical distri-bution system to allow for efÞ cient op- eration of the vessels as well as provid-ing blackout prevention. This system as approved by ABS allows for full DP-2 operation with a closed switchboard bus as well as an open switchboard bus. RAACI is providing three key integral systems for each vessel:1. Active Front End (AFE) Variable Fre- quency Drives (VFDs) and Motors for the Propulsion and Thruster System: 2. Full Electrical Distribution System with Power Management3. Alarm & Monitoring System (ABS ACCU & DP-2)In addition it is also providing three Air cooled, 495kW FIFI motors New DPS from GE Power Conversion GE?s DP system?enhancing situation awareness and rebalancing attention from system management to true sea-manship. GE?s Power Conversion busi- ness launched enhanced operability to the company?s Dynamic Positioning (DP) system at OTC in Houston. In es-sence, the company claims that the de-velopment puts DP back into the marine world, which the company claims was achieved via a new human-machine in-terface (HMI). The control panel is de- signed to be clean and uncluttered with very few control devices. Its 26-inch touchscreen is tiltable to suit each opera-tor?s preference for standing or sitting in front of the screen, or moving around it. It accommodates operators of differ- ent heights and is equally visible in a whole range of lighting conditions on the bridge, especially reß ections from the sun and artiÞ cial light. Screen displays in an operator selectable range of lan-guages allow the operator to access all system functionality in his/her mother tongue.GE Power Conversion has put consid-erable time and effort into improving the ergonomics of the HMI. The new DP control system - part of GE?s eco- magination portfolio - also embodies improvements to energy ef Þ ciency and sustainability. The system includes a new ?Energy-Ef Þ ciency? mode, which can be used when appropriate. GL Certi es SimulationX ITI GmbH said that for the Þ rst time a marine application of the interdisciplinary simula-tion software SimulationX has passed Germanischer Lloyd?s (GL) type approval certiÞ ca-tion. The SimulationX software module ?Marine Propeller? for the calculation of ice impact in-duced loads on the powertrain was designed and developed by ITI in collaboration with GL in accordance with the speciÞ ca-tions laid down by GL, the Finnish-Swedish Maritime Administration and the IACS. The software certi Þ cation conducted by GL proves the software?s high quality standards and is evidence of ITI?s commitment to safe, reliable and en- ergy ef Þ cient ship propulsion systems. According to the new speci Þ cations for ice classes that were elaborated by the Finnish and Swedish Maritime Adminis- tration, it is required to evaluate the impact of propeller-ice-torque excitation on the drive shaft. The ship?s operational safety and the material?s durability must be demonstrated under various conditions including Artic temperatures and critical scenarios. By the help of physically correct simulations, SimulationX users predict vibration loads originating from ice impact on the propeller. These extreme conditions are analyzed with SimulationX on a virtual basis over a longer period of time and for various parameter conÞ gurations. The simulation results permit reliable evaluations of each component and thus contribute to ensuring safe operation also under arctic conditions. The SimulationX propel- ler model allows for accurate calculations of torsional vibrations with respect to propeller-ice interactions and the torque loads acting on the powertrain as a consequence of ice impact based on the Baltic and polar ice class deÞ nitions. www.itisim.com www.simulationx.com MR #6 (74-81).indd 77MR #6 (74-81).indd 775/31/2013 10:44:39 AM5/31/2013 10:44:39 AM
