Kaydinta sabbaynta badda ee badda (FPSO) waa warshad saliideed oo dhammaystiran oo badda ku jirta oo isku xidha kaydinta, kala-soocidda iyo gaadiidka badeecadaha saliidda cayriin.Saliida ceyriinka ah ee laga soo saaro ceelasha badda hoosteeda waxaa la soo mariyaa dhuumaha badda hoosteeda mara, waxaana lagu farsameeyaa markabka waxaana lagu keydiyaa haamaha xamuulka, halkaas oo ugu dambeyntii lagu daabulo booyadaha iyada oo loo marayo habka dejinta.
Super duplex ahama birta waxay leedahay maaddo molybdenum sare leh, taas oo si weyn u wanaajisa iska caabbinta daxalka ee birta, taas oo aad ugu habboon isticmaalka muddada dheer ee deegaanka ay ku jirto maadada chloride-ka sare, sida biyaha badda, waxaana si weyn loogu isticmaalaa qalabka badbaadada, dhuumaha. , munaaradaha desulfurization iyo qaybaha kale ee modules FPSO.
Macaamiisha noocan oo kale ah guud ahaan waxay leeyihiin shuruudaha soo socda ee guryaha dhigaalka biraha alxanka ee super duplex ahama (birta saldhiga UNS S32750/S32760, iwm):
