Offshore Floating Storage Vessel (FPSO) ni uruganda rwuzuye rwa peteroli rwo mu mahanga ruhuza kubika, gutandukanya no gutwara ibikomoka kuri peteroli. Amavuta ya peteroli akomoka mu mariba yo mu nyanja yakirwa binyuze mu miyoboro yo mu nyanja, igatunganyirizwa mu bwato ikabikwa mu bigega bitwara imizigo, aho amaherezo ijyanwa mu bigega bitwara ibicuruzwa binyuze muri sisitemu yo gupakurura.
Ibyuma bya super duplex bidafite ibyuma bifite molybdenum nyinshi, biteza imbere cyane kwangirika kwangirika kwibyuma bitagira umwanda, bikwiriye cyane gukoreshwa igihe kirekire mubidukikije birimo ioni ya chloride nyinshi, nkamazi yo mu nyanja, kandi ikoreshwa cyane mubibaya byumutekano, imiyoboro. , umunara wa desulfurizasi nibindi bice muri moderi ya FPSO.
Abakiriya nkabo muri rusange bafite ibisabwa bikurikira kubijyanye no kubika ibyuma byo gusudira ibikoresho byo gusudira byuma bya super duplex bidafite ibyuma (bihuye nicyuma fatizo UNS S32750 / S32760, nibindi):

Kubiranga gusudira hamwe nibisabwa bijyanye na tekiniki ya super duplex idafite ibyuma, isosiyete yacu ifite ibikoresho byo gusudira bihuye bihuye, bisobanurwa gutya:
