less noise in environmentIn general, electric <strong>drives</strong> <strong>and</strong> systems generate less noisethan hydraulic systems. There<strong>for</strong>e, there are less restrictionson m<strong>ac</strong>hinery pl<strong>ac</strong>ement onboard. M<strong>ac</strong>hinery can, <strong>for</strong>instance, be installed close to <strong>ac</strong>commodation 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 <strong>for</strong> 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 <strong>marine</strong> diesel engine. Additionallyusing frequency converters <strong>for</strong> bow thrusters, fire pumps<strong>and</strong> other large power consumers eliminates the need to reservepower <strong>for</strong> the startup current peak. Consequently, theuse of the starting auxiliary generators just <strong>for</strong> the startupcan often be avoided.M/S Speciality, an all-electric tankerapplicationsRequirements in <strong>marine</strong> <strong>and</strong> <strong>offshore</strong> rise from the ambient conditions <strong>and</strong> also from the supply network of vessel <strong>and</strong> sp<strong>ac</strong>e<strong>and</strong> fuel save requirements. Tens of thous<strong>and</strong>s of V<strong>ac</strong>on AC <strong>drives</strong> are already running onboard vessels of every kind. Theyvary from the smallest helper <strong>drives</strong> to the megawatt’s propulsion <strong>and</strong> from simple ventilation to the most complicated winchsystems. And all of them are made to last. V<strong>ac</strong>on AC <strong>drives</strong> fully comply with the rules of the <strong>marine</strong> approval societies.cargo rampcargopumptop drivehatchcovercargocranecabinetventilationanchorwinchtensionertrawlingwinchstoragewinchmooringwinchcargo rampmainpropulsionsteeringgearazimuththrusterseawaterpumpm<strong>ac</strong>hine roomventilationcompressorpowergenerationmudpumpsdrawworkazimuththrustertunnelthruster3
