Summary Information

Brief Description

  • The 260-meter long Sanha LPG FPSO has the ability to process over 37,000 barrels of LPG per day into propane and butane products.
  • The FPSO is permanently moored to the seabed by an external turret mooring system
  • The vessel receives through pipelines the associated gasses of propane and butane that are produced together with crude oil from the sea bottom.
  • Then, LPG-FPSO separates the associated gas into pure propane and butane, with the process plant on the deck and cools them with the refrigeration unit, then stores them in tanks in the hull, and offloads the LPG into LPG carriers assigned from time to time
