Cargo pumping system of the 22,000dwt product tanker CHEMBULK SAVANNAH


The cargo pumping system includes 24 Wärtsilä Svanehoj cargo pumps, driven by electric motors under frequency converter control. Pumps handle cargoes with a maximum density of 1.5t/m3. Using 12 Vacon frequency converters, the system is designed for a maximum of 12 pumps to be operated simultaneously, either under remote control from the cargo control room or under local control from the converter switchboard front panel. The cargo piping system is designed for a maximum pressure of 16 bar, with automatic switch off, if a valve in the discharge system is closed in error.
