Izimiso Zokuzulazula Zemikhumbi Yezimpahla
Ukuzulazula ngemikhumbi yezimpahla kuyiqoqo lolwazi, amakhono, kanye nezinqubo ezisetshenziswa ukuhambisa umkhumbi usuka kwelinye ichweba uye kwelinye ngokuphephile, ngempumelelo, nangesikhathi. Phakathi kwezinguquko zesimo sezulu sasolwandle, ubuningi bemizila yemikhumbi, kanye nezidingo zamaketanga okuphakelwa emhlabeni wonke, ukuzulazula kungaphezu nje "kokuqondisa umkhumbi," kodwa kuhilela ukuhlela okuqhubekayo, ukuqapha, ukwenza izinqumo, kanye nokuphathwa kwezingozi. Lesi sihloko sixoxa ngezimiso ezibalulekile zokuzulazula ngemikhumbi yezimpahla ezakha isisekelo sokuphepha kwasolwandle kwanamuhla.
1. Ukuhlela Indlela Ehlelekile
Isimiso esibaluleke kakhulu ukwenza ukuhlela uhambo oluphelele ngaphambi kokuhamba. Ukuhlela indlela kuhlanganisa ukunquma umzila, izindawo zokuhamba, isikhathi esilinganiselwe sokufika (i-ETA), izidingo zikaphethiloli, kanye nokuhlonza izindawo eziyingozi njengamanzi angajulile, ithrafikhi enkulu, izindawo ezivinjelwe, kanye nezindawo ezivame ukuba nesimo sezulu esibi.
Empeleni, ukuhlela kuvame ukuhlukaniswa ngezigaba ezine: ukuhlolwa (ukuqoqa ulwazi), ukuhlela (ukuthuthukisa imizila nezinqubo), ukwenziwa (ukwenza uhlelo), kanye nokuqapha (ukuqapha nokulungisa). Imithombo yedatha esetshenziswayo ifaka amashadi olwandle (iphepha noma i-ECDIS), Izaziso Zasemanzini, ulwazi lolwandle, izincwadi zechweba, kanye nezibikezelo zesimo sezulu. Uhlelo oluhle luhlanganisa nezinyathelo zokubhekana nezimo: okufanele ukwenze uma injini ihluleka, ukubonakala okunciphile, noma ushintsho endleleni ngenxa yezimo zokusebenza.
2. Ukunquma Indawo Yomkhumbi Ngokunembile Nangezikhathi Ezithile
Ukunquma ngokunembile indawo yomkhumbi (ukulungisa indawo) kuyisimiso esiyinhloko sokuzulazula. Imikhumbi yesimanje yezimpahla ithembele ku-GNSS/GPS njengomthombo wayo oyinhloko, kodwa izimiso zobungcweti zidinga ukuqinisekiswa okuhlanganisiwe nezinye izindlela zokunciphisa ingozi yamaphutha ezinzwa, ukuphazamiseka kwesignali, noma amaphutha okufaka.
Izindlela zokubeka indawo zingafaka:
– Ukulungiswa kwe-radar: ukusebenzisa ibanga kanye nesiqondiso sezinto ezisogwini noma ama-buoy.
– Ama-bearing abonakalayo: ukubonwa kwezindlu zokukhanyisa, izindawo eziphezulu, noma izimpawu zokuhamba.
– Ukuzwakala kokujula: kuqhathanisa ukujula okulinganisiwe nemingcele yokujula ebalazweni.
- Ukubala okungapheli: ukulinganisa isikhundla ngokusekelwe endleleni, isivinini, kanye nomsinga.
Ukuhlolwa kwesimo okuvama kufanele kulungiswe ngokwezimo: kuvame kakhulu emanzini amancane, eduze nogu, noma ezindaweni eziminyene, futhi kuvame ukwenzeka olwandle oluphakeme. Ukulungiswa ngakunye kufanele kuqoshwe futhi kuhlaziywe ukuthambekela kokuphambuka ukuze kutholakale ithonya lamanzi nomoya.
3. Ukusetshenziswa Kahle Kwamamephu Nezinhlelo Zokuzulazula Ze-elekthronikhi
Amashadi olwandle "awulimi" lokuzulazula. Emikhumbini yezimpahla, amashadi angaba amashadi ephepha, kodwa i-ECDIS (Ukubonisa Ishadi Le-elekthronikhi kanye neSistimu Yolwazi) iyanda kakhulu. Isimiso akusikho nje ukuba ne-ECDIS, kodwa futhi ukuqinisekisa:
- Imephu ye-elekthronikhi ebuyekeziwe (i-ENC), kufaka phakathi ukulungiswa kwakamuva.
– Ukubeka umugqa wokuphepha, ukujula kokuphepha, kanye nama-alamu ngokuya ngomklamo womkhumbi kanye nomkhawulo wokuphepha.
– Imizila iyaqinisekiswa ukuze kugwenywe ukuwela izindawo ezingajulile noma izindawo ezingavunyelwe.
- Ukuqonda izindlela zokubonisa (enyakatho-phezulu, phezulu), isikali, kanye nemikhawulo yedatha.
Iphutha elivamile emikhunjini ukuthembela kakhulu ezikrinini ngaphandle kokuhlola isikali, izilungiselelo ze-alamu, noma ukufaneleka kwedatha. Ngakho-ke, ikhono lomqhubi, ukuhlolwa okuvamile, kanye nezinqubo zokuhlola phakathi kwe-ECDIS, i-radar, kanye nokubuka okubonakalayo kuyizimiso ezibalulekile.
4. Ukuphathwa Kwezingozi Zokuhamba Nokuqwashisa Ngezimo
Ukuzulazula okuhle kudinga ukuqaphela isimo: ukuqonda okwenzekayo eduze komkhumbi manje nokubikezela okuzokwenzeka emizuzwini embalwa ezayo kuya emahoreni. Lesi simiso sihilela ukuqaphela njalo:
– Ithrafikhi yemikhumbi (i-AIS, i-radar, ukubuka okubonakalayo)
– Isimo sezulu kanye nezimo zamagagasi
– Imikhawulo ekuqondeni kahle komkhumbi (ukungabi namandla, ibanga lokuma, ukujika indilinga)
– Isimo senjini, isiteringi kanye nemishini yokuzulazula
Ukuphathwa kwengozi kusho nokuqaphela “izimpawu zengozi” ngokushesha okukhulu: i-CPA/TCPA enciphayo, ukukhukhuleka okwandayo kokunciphisa umoya, izinguquko zokujula okusheshayo, noma i-alamu esebenzayo ye-ECDIS/radar. Izinqumo ezincane ezenziwe kusenesikhathi zivame ukuphephile kunezindlela ezinkulu ezenziwa sekwephuzile.
5. Ukuthobela i-COLREG kanye neMithethonqubo Yokuthumela
Emanzini omhlaba wonke, ukuvimbela ukungqubuzana kulawulwa yi-COLREG (Imithetho Yomhlaba Wonke Yokuvimbela Ukungqubuzana Olwandle). Imikhumbi yezimpahla kumele ihambisane nezimiso zokuhamba ngemikhumbi ezifana nalezi:
– Gcina ukuqapha okwanele (amadivayisi abonakalayo nazwi, kanye namadivayisi okusiza).
– Setha isivinini esiphephile ngokuya ngokubonakala kanye nokuminyana kwethrafikhi.
- Qonda imithetho yokuwela, ukubhekana ngqo, kanye nokudlula.
- Sebenzisa izibani ezifanele, izimo, kanye nezimpawu zomsindo.
– Thatha isinyathelo esiqinile, esisheshayo, nesiqondakalayo sokugwema eminye imithambo yegazi.
Ukuthobela imithetho ye-COLREG akusiwona nje umthwalo wemfanelo kakaputeni, kodwa futhi nokuxhumana okuhlelekile kweqembu lebhuloho, ukugcina amarekhodi, kanye nesiko lokuxhumanisa.
6. Ukuqonda Izici Eziphathelene Namaza Olwandle: Imisinga, Imimoya, Amaza, Namagagasi
Imikhumbi emikhulu yezimpahla inobunzima obukhulu kanye nomfutho, kodwa isathinteka yindawo ezungezile. Imisinga ingasunduza umkhumbi endleleni, imimoya ingadala amathuba, futhi amagagasi anquma ukujula okusebenzayo lapho ungena khona emseleni wokuthumela noma echwebeni.
Isimiso esibalulekile lapha ukwenza izilungiso:
- Setha futhi uzulazule ukuze uthole umugqa wamanje: isiqondiso samanje kanye nesivinini.
– I-Leeway yomoya ohamba eceleni.
– Ukuhlanzwa kwe-Under-keel (UKC): ibanga eliphephile phakathi kwe-keel kanye nolwandle, ikakhulukazi ngesikhathi sokuma kwamagagasi aphansi kanye nezimo zokulala phansi.
Emanzini angajulile, isimo sokugoba (umkhumbi "ocwila" ngokujulile ngenxa yemiphumela ye-hydrodynamic) singandisa ingozi yokuma komhlaba. Ngakho-ke, ukubalwa kwe-UKC kanye nokuphathwa kwesivinini kubalulekile.
7. Ukuphathwa Kwezinsizakusebenza Zebhuloho (i-BRM) kanye Nokuxhumana Okuphumelelayo
Ukuzulazula kuwukusebenza ngokubambisana. I-BRM igcizelela ukwahlukaniswa okucacile kwemisebenzi ebhulohweni: ukuthi ubani olawulayo, ngubani oqapha i-radar/ECDIS, ubani oqaphayo, nokuthi kwenziwa kanjani izinqubo zokuhlola. Ukuxhumana kumele kube kufushane, kucace, futhi kube yinto ejwayelekile, ikakhulukazi lapho uhamba ngezinyawo emachwebeni, emanzini amancane, noma lapho usebenzisa umshayeli wendiza.
Izimiso ze-BRM zifaka phakathi nekhono lokuphonsela inselelo izinqumo ngobungcweti lapho ungabaza (ukuzibophezela) kanye nokwenza izithangami ngaphambi kwemisebenzi ebalulekile njengokushayela, ukuqinisa, noma ukuhamba nge-Traffic Separation Scheme (TSS). Amaphutha okuhamba avame ukwenzeka hhayi ngenxa yokuntuleka kwemishini, kodwa ngenxa yokungaxhumani kahle, ukuqagela, noma ukuntuleka kokuxhumana.
8. Ukugcinwa Kwemishini Nokulungiselela Okuphuthumayo
Imishini yokuhamba—i-radar, i-gyrocompass, i-autopilot, i-echo sounder, i-AIS, kanye nezinhlelo zokuxhumana—kumele ihlolwe futhi igcinwe. Isimiso sithi: ungalindi ukuthi imishini yehluleke uma kubalulekile. Ukuhlolwa kokusebenza, ukulinganiswa, kanye nohlu lokuhlola lwansuku zonke/lwamasonto onke kusiza ukuvimbela ukwehluleka okungazelelwe.
Ngaphezu kwalokho, abashayeli bezindiza kufanele bahlale benohlelo oluphuthumayo: izinqubo zokucima ugesi, ukulahlekelwa yi-steering, ukwehluleka kwe-GPS, noma ukwehluleka kwenjini. Lokhu kuhlanganisa ukusungula indawo ephephile yokujika, uhlelo lokumisa oluphuthumayo, kanye nokuxhumanisa ukuxhumana ne-VTS/port eseduze.
9. Ukuzulazula Okusebenzayo: Isikhathi, Uphethiloli, kanye Nokukhishwa Kwegesi
Imikhumbi yesimanje yezimpahla ayidingeki nje kuphela ukuze iphephe kodwa futhi isebenze kahle. Izimiso zokusebenza kahle kokuhamba zifaka phakathi ukwenza ngcono imizila kanye nesivinini (umzila wesimo sezulu), ukugcina ukusika okufanele, kanye nokugwema ukuzulazula okungadingekile. Ukunciphisa ukusetshenziswa kukaphethiloli kuthinta ngqo izindleko zokusebenza kanye nokukhishwa kwegesi. Kodwa-ke, ukusebenza kahle akufanele kube yindleko yokuphepha: lapho izimo ziba zimbi, isinqumo sokunciphisa isivinini, ukushintsha imizila, noma ukucasha kuyikhono lobuchwepheshe lokuhamba.
Isiphetho
Izimiso zokuhamba ngemikhumbi yezimpahla zincike ekuhleleni ngokucophelela, ekubekeni indawo efanele, ekusetshenzisweni kahle kwamashadi nezinhlelo ze-elekthronikhi, ekunamatheleni emithethweni yamazwe ngamazwe, kanye nokuqonda okuphelele kwezici zemvelo. Konke lokhu kumele kusekelwe ukuphathwa kwezingozi, ukusebenzisana kwamabhuloho, ukulungiswa kwemishini, kanye nokulungiselela izimo eziphuthumayo. Enkathini yobuchwepheshe bokuhamba ngemikhumbi obuyinkimbinkimbi ngokwengeziwe, isihluthulelo sisalokhu sifana: izinqubo ezihlelekile kanye nokwenza izinqumo ngokucophelela, njengoba ukuphepha komkhumbi, imithwalo, kanye nabasebenzi kusalokhu kuyinto eza kuqala.
