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. Vacon AC drives fully comply with the rules of the marine approval societies.cargo rampcargopumptop drivehatchcovercargocranecabinetventilationanchorwinchtensionertrawlingwinchstoragewinchmooringwinchcargo rampmainpropulsionsteeringgearazimuththrusterseawaterpumpmachine roomventilationcompressorpowergenerationmudpumpsdrawworkazimuththrustertunnelthruster3
