The Sanha LPG FPSO

摘要

The FPSO industry will soon have the first LPG FPSO inrnoperation. The SANHA LPG FPSO is the first gas relatedrnFPSO. With the installation of the LPG FPSO forrnChevronTexaco’s Sanha field development project offshorernAngola by April 2005, SBM will set a new benchmark forrnoffshore processing of LPG. The LPG FPSO will receive LPGrnfrom the Sanha Condensate Complex and several productionrnplatforms via two subsea pipelines and flexible risers. Eachrnstream will be pressurized at near-ambient temperature whenrnloaded on the LPG FPSO.rnOnboard the two streams will be comingled and thenrnseparated into butane and propane fractions by means ofrndistillillation, refrigerated, depressurized to athmosphericrnpressure and stored into the cargo tanks. The paper willrnaddress the main commercial, technical and exectutionrnchallenges that the project team has faced and highlight thernkey success factors as well as “lessons learnt”.
