VIETSOVPETRO 01 154,146-dwt Floating Storage and Offloading Unit
VIETSOVPETRO 01, a 154, 146-dwt FSO (Floating Storage and Offloading Unit) ordered by MODEC, Inc.was completed a Ariake Works of Hitachi Zosen on September 7, 2000 and was delivered to VIETSOVPETRO of Vietnam from MODEC, Inc. on December 12th, 2000.
Features
1. The vessel was newly constructed in a short time from the beginning of November in about 10 months.
2. The cargo oil tanks are double hulled as a precaution against marine pollution.
3. The vessel has an external turret, which takes oil from the seabed and is for mooring in bow.
4. Oil taken from he turret, is heated by "Inlet Heater Unit". After that, oil is stored in "Process Tank" temporarily, which separates oil and seawater by gravity. Oil in upper position of "Process Tank" is shifted to other cargo oil tanks by main gravity and seawater in the lower side of "Process Tank" is shifted to Slop Tanks by main gravity. Seawater in slop tanks is shifted to "Hydro Cyclone Unit", which separates further, seawater and oil further. Separated oil is shifted to "Process Tank" again. Oil is separated nearly 100% from seawater by this process.
5. Oil which is stored in cargo oil tanks, is shifted to shuttle tanker after shifted value of oil is measured by "Metering Unit".
6. All pipes and valves for cargo and ballast are installed in "Pipe Duct" which is arranged in center of double bottom considering the easy maintenance in operation. "Pipe Duct" has a traffic device, by which crew can access in the longitudinal direction of FSO.
