Kubunjiniyela bezolwandle emhlabeni jikelele, ukuphepha nokuthembeka kuncike kakhulu ekusebenzeni kahle kwamapuleti ensimbi asetshenziselwa izakhiwo zemikhumbi, amapulatifomu asogwini lolwandle, kanye nezingxenye zangaphansi kolwandle. Njengoba amazinga okwakha imikhumbi eqhubeka nokuthuthuka, amazinga ensimbi afana nalawaAH36, DH36, EH36, kanye namanye amapuleti esakhiwo anamandla aphezulu kumele afinyelele ukuqina okuphezulu, ukuzinza, kanye nokuqina. Phakathi kwezinqubo ezibalulekile ezichaza lezi zakhiwo zemishini, izindlela zokujwayeza kanye nokucima zidlala indima ebalulekile. Abakhiqizi abaphambili, kufaka phakathi i-sakysteel, basebenzisa ubuchwepheshe obuthuthukisiwe bokwelapha ukushisa ukuqinisekisa amandla nokusebenza kahle kuwo wonke amapuleti anikezwa embonini.
Lesi sihloko sihlola ukuthi izinqubo zokulungisa nokucima zithuthukisa kanjani amapuleti ensimbi okwakha imikhumbi, izimiso zobuchwepheshe ezisekela indlela ngayinye, kanye nezinhlelo zokusebenza ezithembele emandleni athuthukisiwe esakhiwo.
Isingeniso Sokwelashwa Kokushisa Ensimbini Yokwakha Imikhumbi
Ipuleti lensimbi yokwakha imikhumbi kumele libhekane nezinselele eziningi zemvelo nezomshini ezifana nokushayisana kwamagagasi, imithwalo eguquguqukayo, ukuphuka kwezinga lokushisa eliphansi, kanye nokugqwala. Ukuze kuhlangatshezwane nalezi zidingo, abakhiqizi basebenzisa amasu okwelapha ukushisa acwengisisa isakhiwo sokusanhlamvu, andise ukuguquguquka, futhi athuthukise ukuqina. Izindlela ezimbili eziphumelela kakhulu zokuthuthukisa amandla kanye nokufana kwesakhiwo ukuvuselela nokucima kulandelwe ukulinganisela.
Zombili lezi zinqubo zithonya isakhiwo sangaphakathi sensimbi, zisiza amapuleti okwakha imikhumbi ukuba alondoloze izakhiwo ezihlala njalo ngisho nangaphansi kwezimo ezinzima zasolwandle.
Kuyini Ukulungisa Izinto?
Ukulungisa insimbi ngendlela evamile kuyindlela yokwelapha ukushisa esetshenziswa kabanzi ekwakheni insimbi, ikakhulukazi kumagremu adinga ukuqina okuphezulu kanye nokulingana. Le nqubo ihilela ukushisa insimbi ibe ngaphezu kwephuzu layo lokuguqulwa elibalulekile, ngokuvamile phakathi kwama-degree Celsius angu-880 no-950, bese iyivumela ukuthi iphole emoyeni othule.
Izinjongo Eziyinhloko Zokwenza Kube Nokwejwayelekile
-
Ukuhlunga usayizi wezinhlamvu ukuze kuthuthukiswe ukuqina
-
Ukuthuthukisa ukuguquguquka kanye nokwakheka
-
Ukususa ukucindezeleka okusele ekugoqeni
-
Ukuhlanganisa isakhiwo esincane sensimbi
-
Ukuthuthukisa ukushibilika ngokulinganisela ubulukhuni namandla
Ukulungisa izinto ngendlela evamile kusebenza kahle kakhulu kumapuleti asetshenziswa ezakhiweni ze-shell, izingxenye zedekhi, kanye nokwakhiwa okuvamile kolwandle lapho ukufana nokuthembeka kubalulekile khona.
Izinguquko Zesakhiwo Ngesikhathi Sokujwayela
Uma insimbi ishiswa ibe yizinga lokushisa elijwayelekile, isakhiwo sayo sokusanhlamvu siyashintsha sibe yi-austenite. Ngesikhathi sokupholisa komoya, i-austenite iyashintsha ibe yi-pearlite encane kanye ne-ferrite, okuholela ezicini zomshini ezithuthukisiwe. Isakhiwo esincane esicwengisisiwe siholela ku:
-
Amandla aphezulu okukhiqiza
-
Ukumelana okungcono komthelela
-
Ukufana okukhulu kulo lonke ubukhulu bepuleti
Lokhu kuthuthukiswa kwesakhiwo kuyisizathu esiyinhloko sokuthi kungani izikhungo zemikhumbi zikhetha amapuleti ajwayelekile ezindaweni ezithwala imithwalo eshintshashintshayo.
Kuyini Ukucima Nokuthambisa i-QT
Ukucima okulandelwa ukufudumala, okuvame ukubizwa ngokuthi i-QT, kunikeza amandla amakhulu kakhulu kunokujwayelekile. Ipuleti lensimbi lishiswa lifinyelele ekushiseni okuqinisayo bese liphola ngokushesha, ngokuvamile kusetshenziswa amanzi noma izixazululo ze-polymer. Lokhu kupholisa okusheshayo kuguqula i-austenite ibe yi-martensite, isigaba esiqinile nesiqinile.
Ngemva kokucima, insimbi ifakwa ekushiseni okuphansi, ngokuvamile phakathi kwama-degree Celsius angu-500 no-650, ukuze kuncishiswe ukuphuka nokubuyisela ukuqina.
Inqubo ye-QT ifaka phakathi
-
Ukuqinisa
-
Ukucima okusheshayo
-
Ukunciphisa ukucindezeleka
-
Ukulungiswa kwempahla yokugcina yemishini
Abakhiqizi abanjengo-sakysteel basebenzisa izitofu zokwelapha ukushisa ezenzakalelayo ukuqinisekisa ukunemba kanye nokungaguquguquki ekucutshungulweni kwe-QT.
Ukuthuthukiswa Kwamandla Ngokucima
Ukucima kunomthelela ngqo ekuthuthukisweni kwamandla ngokudala isakhiwo esincane se-martensitic. I-Martensite inobulukhuni obuphezulu kakhulu kanye namandla okuthambekela, okwenza amapuleti acinyiwe afanelekele izinhlelo ezibalulekile zokwakha imikhumbi njenge:
-
Amapuleti esikebhe se-icebreaker
-
Imilenze yesikhulumi sasogwini
-
Amamojula e-FPSO
-
Imishayo ethwala umthwalo ophezulu
-
Izindawo zokusebenza eziphansi zokushisa
Ukuhlanganiswa kwamandla aphezulu kanye nokuqina okuthuthukisiwe kwezinga lokushisa eliphansi kwenza amapuleti ensimbi e-QT afaneleke kakhulu kumaphrojekthi obunjiniyela basolwandle adinga amandla.
Izinzuzo Zesakhiwo Esincane Sokwelashwa Kokushisa Kwe-QT
Inqubo ye-QT iphumela ku:
-
Amandla aphezulu okudonsa
-
Ukuqina okuhle kakhulu komthelela emazingeni okushisa angaphansi kwezinga-zero
-
Ukumelana okukhulu nokukhathala nokucindezeleka okunamandla
-
Ukuqina okuthuthukisiwe ngaphansi kwezimo ezinzima zasogwini lolwandle
Ukushisa ngemva kokucima kuqinisekisa ukuthi insimbi ihlala iqinile kodwa ithambile ngokwanele ukumelana nokusebenza kokushisela, ukugoba, nokwakheka.
Ukuqhathanisa Phakathi Kwezindlela Zokujwayeza Nokucisha
Nakuba zombili lezi zinqubo zithuthukisa ikhwalithi yensimbi, zifeza izidingo zokusebenza ezihlukile.

Izindinganiso Ezilawula Insimbi Yokwakha Imikhumbi Ephathwe Ngokushisa
Amapuleti okwakha imikhumbi kumele ahambisane nezindinganiso eziqinile zezinhlangano ezifana nalezi:
-
I-ABS
-
I-DNV
-
Irejista yeLloyds
-
I-CCS
-
BV
Lezi zindinganiso zichaza izidingo zokwelapha ukushisa, amandla omthelela we-Charpy emazingeni okushisa ahlukene, imikhawulo yokuqina, kanye nezinqubo zokuhlola ngomshini. Izinqubo zokulungisa kanye ne-QT ziqinisekisa ukuthi insimbi ihlangabezana noma idlula lezi zimfuneko.
Ukulawulwa Kwekhwalithi Yokukhiqiza Kwamapuleti Aphathwe Ukushisa
Ukuqinisekisa ukuhambisana kokulungisa nokucima kudinga izinyathelo eziqinile zokulawula ikhwalithi. Lokhu kufaka phakathi:
-
Ukuqapha ukunemba kwezinga lokushisa
-
Ukulawulwa komkhathi wesithando somlilo
-
Ukuhlolwa kokuqina kanye nempahla yemishini
