I-EH36 vs DH36: Ukukhetha iBanga elifanelekileyo lokusetyenziswa kwiArctic nangaphandle kweLwandle

Kwimizi-mveliso yaselwandle neyaselwandle, ukukhetha uhlobo lwentsimbi olufanelekileyo sisigqibo esibalulekileyo esinokuchaphazela ukuthembeka kwesakhiwo, ukhuseleko, kunye nokusebenza kwexesha elide. Phakathi kweentsimbi zokwakha iinqanawa ezinamandla aphezulu ezisetyenziswa rhoqo,I-EH36kwayeDH36zezona zimbini zezona zibalaseleyo. Zombini zenzelwe ukumelana neemeko ezinzima, kodwa iimpawu zazo ezithile zoomatshini, iziqinisekiso, kunye nokufaneleka kwazo kwiindawo zaseArctic naselunxwemeni zahlukile. Eli nqaku libonelela ngothelekiso oluneenkcukacha ukunceda iinjineli, abayili, kunye nabaphathi beeprojekthi benze izigqibo ezinolwazi.

Isishwankathelo se-EH36 kunye ne-DH36

I-EH36yintsimbi yokwakha iinqanawa enamandla aphezulu evunyiweyo yimibutho yokwahlulahlula efana ne-American Bureau of Shipping (ABS) kunye ne-Lloyd's Register (LR). U-“E” kwi-EH36 umele iimeko “ezigqithisileyo”, nto leyo ebonisa ukuqina okuphuculweyo kumaqondo obushushu aphantsi, nto leyo eyenza ukuba ifaneleke ngakumbi kwizicelo ze-Arctic.

DH36Kwelinye icala, yintsimbi enamandla kakhulu enezicelo ezifanayo kodwa yenzelwe ukusetyenziswa okuqhelekileyo elwandle naselwandle. Inika iipropati ezintle kakhulu zoomatshini kunye nokudityaniswa, kwaye yaziwa ngokubanzi ngokusetyenziswa kwiindawo eziphakathi.

Nangona zombini ezi ntlobo zisebenza ekwakheni iinqanawa zaselwandle, ukuqonda umahluko wazo kubalulekile xa kuyilo lweenqanawa kunye nezakhiwo zaselwandle ezichatshazelwe yimithwalo ebandayo kakhulu neguquguqukayo.

Umahluko kwiMichiza

Zombini i-EH36 kunye ne-DH36 ziintsimbi eziqinileyo nezingenamthungo, kodwa umahluko omncinci kwimilo yeekhemikhali uchaphazela ukusebenza kwazo:

  • I-EH36:Iqulethe ikhabhoni, i-manganese, i-phosphorus, i-sulfur, kunye nenani elincinci le-nickel kunye ne-copper. Umxube olawulwayo uphucula ukuqina kobushushu obuphantsi kwaye unciphisa ukuthambekela ekuqhekekeni okuqhekekayo.

  • DH36:Kukho izinto ezifanayo zokudibanisa, kodwa zinemida eyahlukileyo kancinci egxininisa amandla ngaphezu kokuqina okubandayo kakhulu.

Olu mahluko luncinci kodwa lubalulekile, ingakumbi kwiimeko zeArctic apho izinto zichatshazelwa ngamaqondo obushushu angaphantsi kwe-zero kangangexesha elide.

Uthelekiso lweePropati zoMatshini

Iimpawu zoomatshini zentsimbi yokwakha iinqanawa zezona zinto zibalulekileyo ekumiseleni ukufaneleka kokusetyenziswa kweArctic kunye nolwandle. Olu thelekiso lulandelayo lubonisa umahluko ophambili:

1. Amandla okuvelisa

Amandla okuvelisa amele uxinzelelo apho intsimbi iqala ukuguquka ngeplastiki:

  • I-EH36:Amandla okuvelisa aphantsi angama-355 MPa kubukhulu obufikelela kwi-50 mm.

  • DH36:Amandla okuvelisa aphantsi angama-345 MPa kubukhulu obufikelela kwi-50 mm.

I-EH36 inika amandla aphezulu kancinci okuvelisa, inika ukumelana okukhulu nokuguquguquka okusisigxina phantsi kwemithwalo enzima.

2. Amandla okuThamba

Amandla okutsalwa yingcinezelo ephezulu intsimbi enokumelana nayo xa isoluliwe:

  • I-EH36:Amandla okutsalwa aqala kwi-490 ukuya kwi-620 MPa.

  • DH36:Amandla okutsalwa aqala kwi-470 ukuya kwi-630 MPa.

Zombini ezi ntlobo zibonelela ngokusebenza kakuhle kokutsalwa, kodwa ukuqina kwe-EH36 kumaqondo obushushu aphantsi kuyenza ithembeke ngakumbi kwiindlela ze-Arctic.

3. Ukuqina kwempembelelo

Ukuqina kwempembelelo kubalulekile ekuthinteleni ukwaphuka okubuthathaka kwiindawo ezibandayo:

  • I-EH36:Ihlangabezana novavanyo oluqinileyo lwempembelelo kubushushu obuphantsi ukuya kuthi ga kwi -40°C okanye ngaphantsi, kuxhomekeke kwiimfuno zoluntu lokwahlulahlula.

  • DH36:Ifanelekile kwiimeko eziphakathi zaselunxwemeni kodwa ayinaso isiqiniseko sokuqina kwempembelelo xa kushushu kakhulu.

Ukuqina okuphezulu kwe-EH36 phantsi kwamaqondo obushushu aphantsi kwenza ukuba ibe lolona khetho lukhethwayo kwiinqanawa kunye nezakhiwo ezisebenza emanzini aseArctic.

4. Ukwandiswa kunye nokuguquguquka

Ukwandiswa kulinganisa ukuguguleka kunye nomthamo wokufunxa amandla:

  • I-EH36:Ubuncinane bokwandiswa malunga ne-21%, nto leyo enika ukufunxwa okungcono kwamandla xa ithwalwa ngequbuliso.

  • DH36:Ubuncinane bobude obumalunga ne-19%, obuncinci kancinci kune-EH36.

Ukwandiswa okukhulu kuphucula ukusebenza kwe-EH36 kwiimeko eziguquguqukayo nezinokuthambekela kumkhenkce.

5. Ukudityaniswa

Zombini i-EH36 kunye ne-DH36 zenzelwe ukudityaniswa kakuhle. Nangona kunjalo, i-EH36 ifuna ulawulo olucokisekileyo lokudityaniswa kwiindawo ezityebileyo ukuze kulondolozwe ukuqina kobushushu obuphantsi. I-DH36 kulula ukuyidibanisa kwiindawo eziqhelekileyo kodwa isenokungahlangabezani neemfuno zobushushu obuphantsi kakhulu ngaphandle kweenkqubo ezithile.

Izicelo kwiindawo zaseArctic nase-Offshore

Ukukhetha phakathi kwe-EH36 kunye ne-DH36 kuxhomekeke kakhulu kubhenco lokusingqongileyo kunye neemfuno zeprojekthi:

  • Imisebenzi yaseArctic:Iinqanawa zokuqhekeza umkhenkce, amaqonga ase-Arctic aselunxwemeni, kunye neenqanawa zophando zamanzi abandayo ziyazuza kukuqina okuphezulu kwe-EH36 kubushushu obuphantsi.

  • Amaqonga aselunxwemeni:Izakhiwo eziqhelekileyo zaselunxwemeni, iinqanawa eziphakathi, kunye neenqanawa zemithwalo eziqhelekileyo zinokusebenzisa i-DH36 ngokuthembekileyo.

  • Izixhobo zaselwandle:Iikhreyini, iidekhi, kunye neebhulorho kwiindawo ezibandayo zifuna i-EH36, ngelixa izixhobo ezifanayo kwiindawo ezinemozulu ephakathi zingasebenzisa i-DH36.

Ukuqina okuphuculweyo kwe-EH36 kuqinisekisa ukuqina kwesakhiwo kwaye kunciphisa umngcipheko wokungaphumeleli kokuqhekeka kwiimeko ezingaphantsi kwe-zero, okwenza ukuba ifaneleke kwiindawo ezixineneyo.

Ukukhetha iBanga leNsimbi elifanelekileyo

Xa ukhetha phakathi kwe-EH36 kunye ne-DH36, qwalasela ezi zinto zilandelayo:

  1. Iimeko Zokusingqongileyo:Misela amaqondo obushushu aphantsi okusebenza kunye nomthwalo womkhenkce onokubakho.

  2. Iimfuneko zoLawulo:Qinisekisa iziqinisekiso zombutho wohlulo kunye neenkcukacha zeprojekthi.

  3. Ukusebenza koomatshini:Vavanya amandla okuvelisa, amandla okutsalwa, ukuqina kwempembelelo, kunye nobude.

  4. Izinto ekufuneka ziqwalaselwe malunga nokuveliswa kwezinto:Hlola ukunamathela, ubukhulu bepleyiti, kunye neenkqubo zokuvelisa.
