Offshore Floating Storage Vessel (FPSO) ke semela se felletseng sa oli se lebopong se kopanyang polokelo, karohano le lipalangoang tsa lihlahisoa tsa oli e tala. Oli e tala e hlahisoang ka liliba tse ka tlas'a leoatle e amoheloa ka liphaephe tse ka tlas'a leoatle, e sebetsoa ka sekepeng ebe e bolokoa ka litankang tsa thepa, moo e qetellang e isoa likepeng tsa tanka ka mokhoa oa ho laolla.
Super duplex tšepe e sa hloekang e na le molybdenum e ngata, e ntlafatsang haholo ho hanyetsa ho bola ha tšepe e sa hloekang, e loketseng haholo bakeng sa tšebeliso ea nako e telele libakeng tse nang le li-ion tse phahameng tsa chloride, joalo ka metsi a leoatle, 'me e sebelisoa haholo ho li-valve tsa polokeho, liphaephe. , litora tsa desulfurization le likarolo tse ling ho li-module tsa FPSO.
Bareki ba joalo ka kakaretso ba na le litlhoko tse latelang bakeng sa thepa ea tšepe ea ho beha lisebelisoa tsa welding tsa tšepe e sa hloekang ea super duplex (tšepe e tšoanang ea UNS S32750 / S32760, joalo-joalo):
