less noise in environmentIn general, electric drives and systems generate less noisethan hydraulic systems. Therefore, there are less restrictionson machinery placement onboard. Machinery can, forinstance, be installed close to accommodation areas withoutany inconvenience to the crew or passengers.The use of electric propulsion allows the use of severalsmaller generator sets. They can individually be shut downwhen the need for power decreases, e.g. while operating thevessel at low speeds in coastal areas. This also contributesto considerably less audible noise in the environment thanusing a slow-running large marine diesel engine. Additionallyusing frequency converters for bow thrusters, fire pumpsand other large power consumers eliminates the need to reservepower for the startup current peak. Consequently, theuse of the starting auxiliary generators just for the startupcan often be avoided.M/S Speciality, an all-electric tankerapplicationsRequirements in marine and offshore rise from the ambient conditions and also from the supply network of vessel and spaceand fuel save requirements. Tens of thousands of Vacon AC drives are already running onboard vessels of every kind. Theyvary from the smallest helper drives to the megawatt’s propulsion and from simple ventilation to the most complicated winchsystems. And all of them are made to last.

The solution: an eletrical main propulsion system which providesextremely low noise levels as there are no large low-speed diesel engines that can be heardat long distance. The same technology was applied to four similar vessels belonging to thesame series.M/S Speciality• 2 x 900 kW main propulsion drives• 350 kW bow thruster drive• 6 x 150 kW cargo pump drives• 3 x 52 kW drives for slop/ballast pumpsCharacteristic of these oil product tankers is the requirementof the lowest possible noise level. Electric motors arequiet compared to their hydraulic alternative. The usefulnessand efficiency of the variable speed control of a fixedblade propeller is clearly better than the fixed speed with avariable angle. Additionally, the fixed speed propeller alwaysruns at the maximum speed, which causes more mechanicalnoise even at partial loads. In these tankers, all propellersare equipped with a fixed space angle (CP) to ensure asufficient noise performance. The main goal is to avoid noisefrom hydraulic machinery when discharching the cargo. Thisis a clear advantage for the neighbourhood, especially atnight time.An electrical main propulsion drive offers numerous importantbenefits over a diesel-engine direct-driven propeller. Forexample, the power generation plant can be optimized, consistingof several smaller units, thus reducing the emissionsof environmentally harmful gases. The motor speed of thetankers´ main propulsion will be controlled by two 900 kWliquid-cooled Vacon NX drives. Speed control also decreasesthe electromechanical stress for the electrical system andprovides flexibility in power generation and distribution. Alltogether four similar vessels belong to the same series.7
