Masisitimu Epakati & Zvimiro zveChigadzirwa

1. Sisitimu Yekuchengetera & Kugovera Cryogenic Inoshanda Zvakanyanya
   Pakati pechiteshi ichi pane matangi ekuchengetera LNG ane simba guru, ane vacuum yakawanda-layer insulated ane huwandu hwegasi rinobikira zuva nezuva (BOG) rate iri pasi pe0.35%, zvichideredza kurasikirwa kwechigadzirwa uye kusvibiswa kwemhepo panguva yekuchengetera. Matangi aya ane mapombi e cryogenic centrifugal akazara pasi senzvimbo huru yekupa simba. Mapombi aya e variable frequency drive (VFD) anopa simba rekuburitsa simba rakasimba uye rinogadziriswa zvichienderana nekudiwa kwekuzadza mafuta, zvichiita kuti zvive pachena kuti kuvimbika panguva yekushanda kwekuzadza mafuta kwakawanda.
2. Sisitimu Yekuzadza Mafuta Nekukurumidza Uye Yakanyatsorongeka
   Zvishandiso izvi zvinoshandisa ma "mass flow meter" uye ma "cryogenic-specific refueling nozzles", zvakabatanidzwa ne automatic pre-cooling uye circuit circuit. Sisitimu iyi inotonhodza mitsetse yekupa mafuta kusvika pakupisa kwekushanda, zvichideredza kurasikirwa kwechigadzirwa "chekutanga". Maitiro ekupa mafuta anoitwa otomatiki, ane preset quantity/amount control uye otomatiki data logging. Kunyatso gadzira mafuta kuri nani pane ±1.0%, ne "single-nozzle flow rate" inosvika 200 liters paminiti, zvichiwedzera zvakanyanya kushanda kwemagetsi.
3. Dhizaini Yakavandudzwa Yekuchinjika Kwezvakatipoteredza
   Kuti ikwanise kutsungirira kupisa kwakanyanya kunogara kuripo muNigeria, hunyoro hwakawanda, uye ngura yemunyu wegungwa, michina yese ye cryogenic nemapaipi anoshandisa simbi isina tsvina yemhando yepamusoro ine insulation yekunze inodzivirira ngura. Masisitimu emagetsi nemidziyo yemagetsi zvinowana chiyero chekudzivirira cheIP66. Makabati ekudzora akakosha ane michina inodzivirira hunyoro uye inotonhodza, zvichiita kuti michina yepakati ishande zvakanaka kwenguva refu munzvimbo dzakaoma.
4. Sisitimu Yakabatanidzwa Yekuchengetedza & Hungwaru Yekutarisira
   Chiteshi ichi chinoshandisa nzira dzakasiyana-siyana dzekudzivirira dzakanangana neSafety Instrumented System (SIS) neEmergency Shutdown System (ESD), zvichipa kutarisa nguva dzose uye dziviriro yakabatana yehuwandu hwemafuta anobvira mutangi, huwandu hwemafuta, uye nzvimbo chaiyo. Sisitimu yekudzora chiteshi ichi inobvumira kutarisa kure, kuongorora zvikanganiso, uye kuongorora data rekushanda. Inotsigira kubhadhara pasina kubata uye kuzivikanwa kwemotokari, zvichiita kuti zvive nyore kushanda zvine hungwaru, zvinobudirira, uye zvakachengeteka pasina vashandi vakawanda.

Seimwe yenzvimbo dzekutanga dzekuwedzera mafuta eLNG muNigeria, kushanda kwayo zvakanaka hakungosimbisi chete kushanda kwakanaka kwemidziyo mikuru yekuwedzeredza mafuta mumamiriro ekunze egungwa anodziya asiwo kunopa vimbiso yekuwanikwa kwemafuta kwakasimba uye kwakavimbika kwekushambadzira mota nengarava dzeLNG dzakachena muWest Africa. Chirongwa ichi chinoratidza simba rakazara mukupa mhinduro dzemhando yepamusoro uye dzakavimbika dzekushandisa simba rakachena.
