OpJiSave™ Saving System Optimizing Pump and Fan Speed to Current Conditions and Saving Fuel PROVEN TECHNOLOGY DESMI

OptiSaveTM is designed to be integrated in new-build vessels as well as in vessels already in operation and can be fully integrated into the vessels’ IAS/AMS/CAMS/ICAMS system. OptiSaveTM is installed onboard +350 vessels around the world, saving more than +8.7 million USD in fuel every year. Customer Says: Andreas Asimakopoulos dep. tech.manager at Minerva Marine: “We selected OptiSaveTM on several projects both as retrofits and as newbuilds on the basis of sound engineering approach compared to competitive products and rigid support through execution stages. Performance of delivered systems...

Energy Efficiency Design Index (EEDI) and SEEMP OptiSaveTM helps ship owners and designers to meet the requirement for reduction of C02 stipulated in IMO MEPC 62 rules. OptiSaveTM is designed to be integrated in new-build and The EEDI has been developed for the largest and most retrofit applications and can be fully integrated into the energy intensive segments of the world’s merchant fleet overall Control System. and will cover 72% of emissions from new oil and gas tankers, bulk carriers, general cargo, refrigerated cargo Energy Efficiency Design Index (EEDI) The EEDI for new ships aims at promoting...

All implemented DESMI OptiSave™ solutions have shown that the relatively inexpensive installations have an average payback time of less than a year The fact that the installed components have an expected lifetime of ten years or more means that you will see a multiple return of your investment. With OptiSave™ we guarantee the most efficient solution, where energy efficiency and fuel savings are key benefits. The systems directly applicable with DESMI OptiSave™ are: • Seawater cooling systems • Steam condenser cooling system • Fresh water cooling systems • Engine room ventilation • Cargo hold...

OptiSave™ Master Control pane The OptiSave™ Master Control panel has a modular design offering one common control platform for all the different applications and the possibility of combining more applications into the same system. This ensures the highest possible flexibility during the design and installation phase for both new building vessels and retrofitting of existing vessels. The common control platform is also offering the flexibility to upgrade the OptiSave™ systems to include more application over time. The OptiSave™ Master Control panel is a central control unit, which can be installed,...

requency ers The OptiSave™ Frequency Converters are designed for marine application with focus on installation in engine room as close to the pump or fan as possible, to lower installation cost and EMI (Electromagnetic interference). OptiSave™ Frequency Converters offer the following special features: • Designed for harsh marine environment • Design temperature up to 50°C without de-rating • Marine coating of circuit boards (3C3) • Internal components are ruggedized • RFI filters suitable IT-net, with co insulations resistance • Two inbuilt DC chocks for reduction of harmonic distortion • IP54/55...

OptiSave™ Frequency Converters OptiSave™ Frequency Converters with integrated electro mechanic by-pass Special features: • Same features as OptiSave™ Frequency Converters • Automatic or remote control of by-pass function • Test of function VSD in by-pass mode allowing programming of VSD during by-pass operation The OptiSave™ Frequency Converters with integrated electro mechanic by-pass offer a higher operation safety than the standard OptiSave™ Frequency Converters. With this solution, DESMI offers a full by-pass of the frequency converter. For pumps / fans from 11kW to 90kW, the by-pass function...

svs The purpose of the system is to control the seawater cooling pumps to the actual cooling demand at any time by reducing/increasing pump(s)' speed/flow according to the actual needed cooling capacity. OptiSave™ is an intelligent system, which operates the speed/flow of the pumps, taking the following conditions into consideration: • Fresh water temperature (LT) • Sea water outlet temperature (it's kept under scaling temperature for central coolers) • Temperature of electric motors on sea water cooling pumps are monitored • Monitoring of discharge pressure for pumps to ensure water filled central...

Special features for New Building or options: \Z Controlling of priming ejectors in case one of the seawater cooling pumps is used as emergency bilge pump. Dynamic pressure drop monitoring cross coolers and condition controlled flushing Standby function of pumps sj Integrated sequential start Frequency converters on all pumps
