Ukuphepha kwasolwandle kanye nokuphepha ogwini kudinga imikhumbi enokwethenjelwa ekwazi ukuphendula ngokushesha, ukukhuthazela isikhathi eside, nokusebenza okuzinzile ezimweni ezinzima zasolwandle. Aisikebhe sokuqaphaidlala indima ebalulekile ekugcinweni komthetho, ekuqapheni umngcele, umkhankaso wokusesha nokuhlenga, kanye nokuvikela itheku.
Lesi sihloko sichaza ukuthi isikebhe sokuqapha sisebenza kanjani, yiziphi izingxenye ezenza siphumelele, nokuthi izinhlangano zingakhetha kanjani umkhumbi ofanele izidingo zokusebenza. Futhi yethula izici zesakhiwo, imingcele ebalulekile yobuchwepheshe, izinzuzo zokusebenza, nemibuzo evamile abathengi abavame ukuba nayo lapho bekhetha isikebhe sokuqapha.
Isikebhe sokuqapha siwumkhumbi okhethekile wasolwandle oklanyelwe ukuqapha, ukuvikela, kanye nemisebenzi yokuphoqelela kuwo wonke amanzi asogwini, amachweba, imifula, nasezifundeni ezingasogwini. Lezi zikebhe zivame ukusetshenziswa onogada basogwini, ibutho lemikhumbi, iziphathimandla zechweba, namaphoyisa olwandle.
Ngokungafani nemikhumbi emikhulu yasolwandle, izikebhe zokuqapha zigcizelela isivinini, ukuhambahamba, nokuthunyelwa ngokushesha. Ngokuvamile mancane kodwa afakwe amasistimu okuzulazula athuthukile, okokusebenza kokuxhumana, nezici zokuphepha ezivumela abasebenzi ukuthi baqaphe izindawo ezinkulu zasolwandle ngempumelelo.
Izinhlangano zivame ukubhekana nezinselelo ezimbalwa zokusebenza:
Izikebhe zokugada zesimanje zenzelwe ukubhekana nalezi zinselelo ngomklamo owenziwe kahle we-hull, amasistimu okuhambisa amandla aphezulu, kanye nobuchwepheshe obuhlanganisiwe be-onboard.
Ukusebenza kwesikebhe sokuqapha kuhlanganisa ukuqhutshwa kwemishini, amasistimu okuzulazula athuthukile, nokuxhumana kokusebenza. Uhlelo ngalunye lusebenza ndawonye ukuze kuqinisekiswe ukuthi umkhumbi usebenza ngendlela ethembekile ngesikhathi sokugadwa nokuphendula.
Inqubo yokusebenza eyisisekelo ihlanganisa izigaba ezimbalwa ezibalulekile:
Lapho umsebenzi wokugada uqala, izisebenzi zimisa umzila wokuzulazula zisebenzisa i-GPS ye-onboard namasistimu e-radar. Isistimu ye-propulsion, evame ukunikwa amandla yizinjini zedizili noma ama-water-jet drive, ihlinzeka ngokusheshisa okuphezulu nokuzinza.
Lapho sebesolwandle, izinto zokugada zesikebhe zihlola indawo ezungezile ukuze zibone imikhumbi, izinto ezisolisayo, noma izimpawu zokucindezeleka. Ithimba lingakwazi ukuya lapho okuqondiswe khona ngokushesha, lixhumane neziphathimandla, noma lenze imisebenzi yokuhlenga uma kunesidingo.
Ukusebenza kahle kwesikebhe sokuqapha kuncike ezinhlelweni zaso ezididiyelwe kanye nokwakheka kwesakhiwo. Izingxenye ezibalulekile zifaka:
I-hull ivamise ukwakhiwa kusetshenziswa i-aluminiyamu yezinga lasolwandle noma ingilazi ye-fiberglass eqinisiwe. Lezi zinto zinikeza ibhalansi yamandla, ukumelana nokugqwala, kanye nesisindo esincishisiwe, okuvumela isikebhe ukuba sifinyelele isivinini esiphezulu.
Isistimu ye-propulsion ngokuvamile ihlanganisa izinjini zasolwandle ezinamandla ezihlanganiswe nama-propeller noma amadrayivu ejethi yamanzi. Amasistimu ejethi yamanzi awusizo ikakhulukazi ezikebheni zokugada ngoba athuthukisa ukuhambahamba futhi anciphisa ingozi yokushayisana kwamanzi.
Imishini yokuzulazula efana ne-radar, i-GPS, i-sonar, nesistimu yeshadi ledijithali ivumela abasebenzi ukuthi bagcine ukuma okunembile futhi bathole imikhumbi eseduze ngisho nasezimeni ezimbi kakhulu.
Ukuqonda imininingwane yobuchwepheshe yesikebhe sokuqapha kusiza abaqhubi ukuthi bahlole ukusebenza kwaso nokufaneleka kwemishini ethile.

Izikebhe zokuqapha zisebenza emikhakheni eminingi yasolwandle. Ukuguquguquka kwazo kuzenza zibe amathuluzi abalulekile kohulumeni, iziphathimandla zetheku, nezikhungo zokuphepha.
Izicelo ezijwayelekile zifaka:
Ngenxa yokuthi izikebhe zokuqapha ziklanyelwe ukuhamba ngokushesha, zikwazi ukunqanda imikhumbi esolisayo ngokushesha kunemikhumbi emikhulu. Leli khono libaluleke kakhulu emizileni yemikhumbi ematasa nasezindaweni ezisogwini.
Intuthuko kwezobunjiniyela basolwandle ithuthukise kakhulu ukusebenza kwezikebhe zokuqapha. Izitsha zanamuhla zinikeza izinzuzo eziningana uma kuqhathaniswa nemiklamo yangaphambili.
Abakhiqizi abanjengoLawadagxila ekuthuthukiseni imikhumbi yokugada ehlanganisa ukusebenza nokuthembeka kokusebenza. Ukuhlanganiswa kobunjiniyela basolwandle obuthuthukisiwe kanye nobuchwepheshe bokuzulazula kuvumela lezi zikebhe ukuthi zisebenze kahle ezindaweni ezidinga kakhulu.
Ukwengeza, i-hull hydrodynamics ethuthukisiwe inciphisa ukudonsa nokuthuthukisa ukuzinza, okubalulekile uma kusebenza emanzini asogwini olunzima.
Ukukhetha isikebhe esifanele sokuqapha kudinga ukuhlola izidingo zokusebenza nezimo zemvelo. Abathengi kufanele bacabangele izici ezimbalwa ezibalulekile ngaphambi kokwenza isinqumo.
Isibonelo, ama-ejensi aqinisekisa ukuthotshelwa komthetho wasogwini angase abeke eqhulwini isivinini esikhulu kanye namandla okunqamula, kuyilapho amathimba aqapha indawo ezungezile angase adinge ububanzi obude bokuhamba ngomkhumbi kanye nemishini yokubuka.
Ukusebenza nomkhiqizi onolwazi kuqinisekisa ukuthi idizayini yesikebhe sokuqapha ihlangabezana nezidingo ezithile zokusebenza ngenkathi kugcinwa amazinga okuphepha nokusebenza.
1. Siyini isivinini esijwayelekile sesikebhe sokuqapha?
Izikebhe eziningi ezigadayo zisebenza phakathi kwamafindo angama-25 kuya ku-45 kuye ngokumiswa kwenjini, ukwakheka kwe-hull, kanye nokusabalalisa isisindo.
2. Isikebhe sokuqapha singahlala isikhathi esingakanani olwandle?
Ukukhuthazela kokusebenza kuncike kumthamo kaphethiloli kanye nesivinini sokuhamba ngomkhumbi. Izikebhe eziningi zokugada zingasebenza amamayela angamakhulu amaningana we-nautical ngaphambi kokugcwalisa uphethiloli.
3. Yiziphi izinto ezisetshenziswa kakhulu ekwakhiweni kwezikebhe zokugada?
I-aluminium yasolwandle kanye nezinhlanganisela eziqinisiwe ze-fiberglass yizinto ezivame kakhulu ngoba zinikeza amandla amahle kakhulu ngenkathi zigcina umkhumbi ungasindi.
4. Ingabe izikebhe ezigadayo zifanelekile emisebenzini yokuhlenga?
Yebo. Izikebhe eziningi zokugada zifakwe izinto zokuhlenga, izinsiza zokwelapha, nezinkundla zokugibela, okuzenza zibe zilungele imisebenzi yokusesha nokuhlenga.
Izikebhe zokuqapha ziyimpahla ebalulekile yokuphepha kwasolwandle, ukubhekwa, kanye nezimpendulo eziphuthumayo. Isivinini sazo esikhulu, ukusebenza kahle, kanye nezinhlelo ezithuthukile zasemkhunjini zinika amandla ukuqapha okusebenzayo kwamanzi asogwini nasogwini.
Ngokuthuthuka okuqhubekayo kubuchwepheshe basolwandle, izikebhe zokugada zesimanje ziletha ukuphepha okuthuthukisiwe, ukusebenza, nokusebenza kahle. Izinkampani ezifanaLawadabazibophezele ekuklameni imikhumbi ethembekile egadayo ehlangabezana nezidingo eziguqukayo zeziphathimandla zasolwandle nezinhlangano zokuphepha.
Uma ufuna isikebhe sokuqapha esinokwethenjelwa esidizayinelwe ukuqina, isivinini, nokusebenza kwasolwandle okuphrofeshinali, ithimba e-Lawada lingakunikeza izixazululo eziklanyelwe ngokusekelwe kuzidingo zakho zemishini.
Ukuze uthole imininingwane eningiliziwe, izinketho zokwenza ngokwezifiso, nokubonisana nochwepheshe,Xhumana nathi ukuze ufunde ukuthi isikebhe esilungile sokuqapha singaqinisa kanjani imisebenzi yakho yasolwandle.
