BALLAST CONTROL SYSTEM (FPSO)
BALLAST CONTROL SYSTEM (FPSO) A Ballast tank is a compartment within a boat, ship or other floating structure that holds water. The ballast system keeps the offshore unit in a stable condition and at a suitable draught, heel and trim in all relevant states of operation. In order to provide adequate stability to vessels at sea, ballast is used to weight the ship down and lower its centre of gravity. The segregated ballast system is designed in floating production storage and offloading (FPSO) to comply with International Convention for the Prevention of Pollution from Ships (MARPOL) regulations. It has ballasting/ de-ballasting and transfer functions from one tank to any other ballast tanks. Ballast filling is via ballast main pipes which run to the ballast seawater from topside seawater lift pumps or topside utility pumps using gravity filling. In previous FPSO projects, the ballast pumps were located in pump room, but recently projects have installed the hydraulic operated, submersib
