Iikhreyini zeplatifomu zaselwandle ziphakathi kwezixhobo ezibalulekileyo kwishishini leoyile negesi. Zinoxanduva lwazo zonke iinkqubo zokuphakamisa eplatifomu — ukusuka ekudluliseleni izinto kunye nezixhobo phakathi kweenqanawa kunye nezakhiwo, ukuya ekusingatheni imisebenzi yokulungisa, kwaye kwezinye iimeko, ukudluliselwa kwabasebenzi. Ngokungafaniyo neekhreyini ezisemhlabeni, iikhreyini zaselwandle zisebenza kwenye yezona ndawo zinzima kakhulu emhlabeni, apho umoya, amaza, ukugqwala kwamanzi anetyuwa, kunye nemida yendawo kudala imingeni eyahlukileyo.
1. Yintoni echaza iKreyini yePlatform yaseLwandle?
I-crane yaselwandle sisixhobo sokuphakamisa esixhonywe kwi-pedestal esisetyenziselwa ukuhambisa izinto okanye abasebenzi ukuya okanye ukusuka kwiinqanawa kunye nezakhiwo zaselwandle. Ezi crane zihlala zixhonywa kwizakhiwo zeqonga ezizinzileyo (ezixhaswa ezantsi) okanye ezidadayo ezisetyenziswa kwimisebenzi yokubhola kunye nemveliso.
Ngokungafaniyo neekhreyini ezisemhlabeni, iikhreyini ezikude nolwandle zinendawo esisigxina kwisakhiwo kwaye azikwazi ukuhamba xa kuthelekiswa nomthwalo. Umthamo wekhreyini ekude nolwandle uxhomekeke kwizinto ezintathu ezibalulekileyo:
- Ulwakhiwo ikreyini efakelwe kulo
- Iimeko zokusingqongileyo (umoya, amaza, imisinga)
- Indawo yomthwalo xa kuthelekiswa nesakhiwo
Ngenxa yezi zizathu, i-crane engaselunxwemeni ayinakuchazwa kusetyenziswa ipharamitha enye efana "ne-crane ye-50-ton." Endaweni yoko, abathengi kufuneka banike umenzi we-crane ulwazi olubanzi ukuze alinganise ubungakanani be-crane ngokuchanekileyo.
2. Isakhelo soLawulo: iMigangatho ye-API
Uyilo, ulwakhiwo, kunye novavanyo lwee-cranes ezifakwe kwi-offshore pedestal zilawulwa yi-API Specification 2C (Offshore Pedestal-mounted Cranes), epapashwe yi-American Petroleum Institute. Olu lwazi lumisela imida yokusebenza ekhuselekileyo ye-crane kwimisebenzi elindelekileyo kunye neemeko ngokuchaza iMithwalo yoSebenzo oluKhuselekileyo (ii-SWL) ngokusekelwe kuxinzelelo lweeyunithi ezivumelekileyo kunye nezinto zoyilo.
Iimfuno eziphambili phantsi kwe-API Spec 2C ziquka:
- Umthwalo wokusebenza okhuselekileyo (i-SWL) kwirediyasi yokuphakamisa oyifunayo
- Uhlobo lwelifti — iilifti ezingaphakathi nangaphandle kwebhodi
- Ubude be-boom kunye noqwalaselo — oluzinzileyo, olutheleskopu, okanye olugoqekayo/oludibeneyo
- Uhlobo lwenqanawa/ulwakhiwo — exhaswa ezantsi, inqanawa/ibhaji, i-TLP, i-spar, i-semi-submersible, i-drillship, okanye i-FPSO
- Ukuphakama kwamaza okubalulekileyo ekusebenzeni kwekreyini
- Isantya somoya (ii) sokusebenza kwekreyini
- Ukwahlulwahlulwa kwebhayisekile yomsebenzi wekreyini
- Ulwahlulo lweendawo ezinobungozi
Ukongeza, i-API RP 2D inika iindlela ezicetyiswayo zokusebenza ngokukhuselekileyo kunye nokugcinwa kwee-cranes ezijikelezayo ezifakwe kwi-offshore pedestals kumaqonga azinzileyo okanye adadayo, iinqanawa zokuxhasa, ii-jackup rigs, ii-semi-submersibles, kunye nezinye iiyunithi zokubhola eziphathwayo offshore (ii-MODU).
3. Iintlobo zeeKreyini zePlatform zaseOffshore
Iikhreyini zase-offshore ziza ngeendlela ezahlukeneyo, nganye ineenzuzo ezahlukeneyo kwizicelo ezahlukeneyo:
IiKreni zeKnuckle Boom
Iikreyini ze-knuckle boom zinezandla ezigobileyo nezidibeneyo ezinokujikeleza imiqobo kwaye zisebenze kwiindawo ezivalekileyo. Kulindeleke ukuba zilawule imarike yeekreyini ezivalekileyo ngenxa yoyilo lwazo oluncinci, ukuguquguquka, kunye nolawulo oluphezulu lokusebenza kwiindawo ezivalekileyo ezivalekileyo.
Iingenelo eziphambili: Ukonga indawo xa ugobile, ukuhamba kakuhle, ukubeka umthwalo ngokuchanekileyo kwiindawo ezixineneyo
Izicelo eziqhelekileyo: Ubonelelo lweplatfomu, ukudluliselwa kwezixhobo kwiindawo ezixineneyo, imisebenzi yokulungisa
IiKreyini zeTelescopic Boom
Iikhrayini ze-telescopic boom zisebenzisa ii-boom ezinamacandelo amaninzi ezinde nezirhoxayo, zibonelela ngokufikelela okulungisekayo kunye nokuphakama okuphezulu. Zithandwa ngenxa yokuguquguquka kwazo, ukuchaneka komthwalo, kunye nokusebenza okuncinci.
Iingenelo eziphambili: Ukufikelela okuguquguqukayo, ukuphakama okuphezulu, ulwandiso oluchanekileyo lomgca othe tye
Izicelo eziqhelekileyo: Ukuphathwa kweekhonteyina, imisebenzi yemithwalo ngokubanzi, izicelo ezifuna utshintsho oluqhelekileyo lwerediyasi
IiKreni zeLattice Boom
Iikhreyini ze-lattice boom zinesakhiwo se-open-grid boom esibonelela ngomlinganiselo we-boom-to-load olula kuneekhreyini ze-telescopic okanye ze-fixed boom. Ngobunzima be-boom olula, abaqhubi banokuphakamisa imithwalo enzima.
Iingenelo eziphambili: Ubunzima obuncinci bokuzithwala, ukuqina okugqwesileyo, ukumelana nomoya okuphezulu, amandla aphezulu okuphakamisa
Izicelo eziqhelekileyo: Imisebenzi yokuphakamisa izinto ezinzima, ukufakelwa kwezixhobo ezinkulu, ukwakhiwa olwandle
4. Iiparameter zoKhetho oluPhambili
Xa ukhetha i-crane yeplatifomu yolwandle, le parameter ilandelayo ibalulekile:
Ukuphakamisa Amandla kunye neRadiyus yokuSebenza
Ubuchule bekreyini buchazwa ngokudityaniswa kwe-SWL kunye nerediyasi yokusebenza. Ubuninzi be-SWL buyancipha njengoko irediyasi yokusebenza isanda. Abathengi kufuneka bachaze zombini iindlela zokuphakamisa ezikwibhodi (ukuphakamisa imithwalo eqongeni) kunye neendlela zokuphakamisa ezingaphandle kwebhodi (ukuphakamisa imithwalo esuka kwiinqanawa ecaleni).
Ulwahlulo lweMijikelo yoMsebenzi
I-API Spec 2C ifuna ukuba iikhreyini zihlelwe ngokwexesha lomsebenzi. Ukuhlelwa okuqhelekileyo kuquka:
- Umsebenzi Wemveliso — Kwimisebenzi yeqonga eqhelekileyo
- Umsebenzi oPhakathi — Wokuphakamisa rhoqo
- Umsebenzi Wokugrumba — Kwimisebenzi yenkxaso yokugrumba eyenzeka rhoqo, nefuna amandla amaninzi
Iikhrayitheriya zoYilo lweNdalo
Abathengi kufuneka bachaze:
- Ukuphakama kwamaza okubalulekileyo ekusebenzeni kwekreyini
- Isantya somoya (ii) sokusebenza kwekreyini
- Ukuphakama kwekreyini ukusuka kwiphini lesithende ukuya kwidekhi yokufakela kunye nokusuka kwidekhi yokufakela ukuya kwinqanaba eliphakathi lolwandle
Ulwahlulo lweNdawo enobungozi
Amaqonga aselunxwemeni adla ngokuba neendawo ezibekwe njengezinobungozi ngenxa yokubakho kweegesi okanye umphunga ovuthayo. Iikhreyini kunye neebhombu zazo kufuneka zenzelwe udidi olufanelekileyo lweendawo ezinobungozi.
Iikhreyini zeplatifomu zaselwandle ziinxalenye zobunjineli ezintsonkothileyo ekufuneka zisebenze ngokukhuselekileyo nangokuthembekileyo kwenye yezona ndawo zinzima emhlabeni. Ukuqonda iziseko - ukusuka kwimigangatho ye-API kunye neentlobo zeekhreyini ukuya kwimingeni yokusingqongileyo, iiparameter zokukhetha, kunye neenkqubo zokhuseleko - kubalulekile kuye nabani na obandakanyeka ekuthengweni, ekusebenzeni, okanye ekugcinweni kwezi mpahla zibalulekileyo.
Nokuba uchaza i-crane entsha yeqonga laselwandle, uvavanya iindlela zokulungisa, okanye ufuna nje ukujula ukuqonda kwakho ngezi zixhobo zibalulekileyo, iziseko ezigutyungelwe kweli nqaku zibonelela ngesiseko esiqinileyo sokwenza izigqibo ezinolwazi.
