Amasu Okuzulazula Okuhamba Ngomkhumbi Emanzini Amancane
Ukuhamba emanzini amancane—njengezinsika, imifula, imisele, iziteshi zechweba, noma izindlela eziphakathi kwamaqembu eziqhingi—kudinga ukunemba okukhulu kunamanzi avulekile. Indawo yokuqondisa ilinganiselwe, imisinga ingaba namandla futhi iguquguquke, ukwanda kobuningi bezimoto kuyanda, futhi izingozi zokuhamba (amatshe asolwandle, izindawo ezijulile, imikhumbi edilikile, ukufakwa kwamanzi) zivame ukuba seduze kakhulu nendlela ephephile. Ngakho-ke, ukuhamba emanzini amancane akuyona nje indaba “yokulandela imephu,” kodwa kunalokho inhlanganisela yokuhlela, izendlalelo eziningi zokuqapha indawo, ukuxhumana, kanye nokulawula imikhumbi okuhlelekile. Lokhu okulandelayo amasu abalulekile avame ukusetshenziswa ukuqinisekisa ukuhamba okuphephile nokusebenza kahle emanzini amancane.
1. Ukuhlela okuningiliziwe kokudlula
Isihluthulelo sokuphepha emanzini amancane siqala ngaphambi kokuba umkhumbi uqale. Ukuhlela indlela yokuhamba kufanele kube nemininingwane eminingi kunalapho uhamba olwandle oluvulekile. Indlela ehleliwe kufanele ifake:
- Ukusetha indawo yendlela engokoqobo kulandela indlela kanye namajika, kucatshangelwa ububanzi bendlela, ibanga eliphephile ezingozini, kanye nendawo lapho isondo lidlula khona.
– Ukuhlonza izingozi: izindawo ezingajulile, amatshe, amakhorali, izindawo ezingavunyelwe, izintambo/amapayipi angaphansi kwamanzi, kanye nezindawo zokudoba ezibanzi.
– Idatha yokuma kolwandle kanye nokwamanje: izikhathi zokuma kolwandle eziphezulu neziphansi, isivinini samandla aphezulu, kanye nesiqondiso samandla ezindaweni ezibucayi. Emanzini amancane, imisinga "ingasheshisa" ngenxa yomphumela wokuxhumanisa.
– Imikhawulo yokusebenza komkhumbi: ukudonswa kwendiza, i-UKC (ngaphansi kwe-keel clearance), ukukwazi ukuhamba, ibanga lokuma, kanye nomthelela womoya emkhunjini (ukugoba).
– Izinhlelo zesimo esiphuthumayo: izindawo zokumisa eziphuthumayo, izindawo zokujika, izindawo zokukhosela, kanye nezinqubo uma injini/isiteringi sihluleka.
Ukuhlela okuhle kuhlanganisa nokuhlukaniswa kwemisebenzi ebhulohweni, okuhlanganisa nokuthi ubani oqapha i-radar, i-ECDIS, izimpawu ezibonakalayo, nokuthi ubani oxhumana ne-VTS noma eminye imikhumbi.
2. Ukusetshenziswa kwamashadi nezincwadi zasemanzini ezibuyekeziwe
Ezindaweni ezincane, izinguquko ekujuleni kanye nezimpawu zokuzulazula zingase zenzeke ngenxa yokubola, ukuguguleka, noma izinguquko ekuphathweni kwechweba. Ngakho-ke, amashadi olwandle (amashadi ephepha kanye ne-ECDIS) kumele abuyekezwe. Ngaphezu kwamashadi, ezinye izinkomba ezibalulekile zifaka:
– Iziqondiso Zokuhamba Ngomkhumbi/Incwadi Yomshayeli Wendiza ukuze uthole izici zendawo.
– Amathebula okuphakama kolwandle kanye nokwamanje (kufaka phakathi i-atlas yomfudlana wolwandle uma ikhona).
– Isaziso ku-Mariners noma izibuyekezo ezisemthethweni zendawo.
Idatha yamuva isiza ekugwemeni "izimanga" ezifana nama-buoy ahambayo, ukujula okuncishisiwe, noma ukuba khona kwezindawo zokusebenza zasolwandle.
3. Indlela yokubeka enezingqimba (ukubeka okuphambene nokuhlola)
Ezindaweni ezivalekile, ukuthembela emthonjeni wesikhundla esisodwa kuyingozi. Kungcono kakhulu ukuqinisekisa izikhundla usebenzisa izindlela eziningi, isibonelo:
– I-GNSS (GPS) / i-ECDIS njengereferensi eyinhloko.
– Ukulungiswa kwe-radar kusebenzisa ibanga kanye nokuthwala ukuya entweni ecacile yasogwini, inhloko, noma i-buoy.
– Ukulungiswa okubonakalayo ngokusebenzisa i-cross bearing ngokumelene nama-beacons, izibani, noma izinto zomhlaba ezibonakalayo.
– I-Echo sounder yokuqapha ukufaneleka kokujula ku-contour elindelekile, ikakhulukazi uma amanzi ethambekele ekungcoleni.
Umqondo obalulekile lapha “ukuqapha, hhayi nje ukuhlela”: hhayi nje ukumaka indawo, kodwa ukuqapha ngenkuthalo ukuthi umkhumbi uyaphambuka yini emzileni, ukuthi ukuphambuka kushesha kangakanani, nokuthi yini ebangela lokho (imisinga eseceleni, umoya, noma umphumela wokuxhumana komkhumbi nomphetho wesiteshi).
4. Ukugcina ithrekhi: ukukhomba okuhambisanayo kanye nokulawula ithrekhi
Enye indlela ye-radar esebenza kahle kakhulu emanzini avaliwe i-parallel indexing (PI). Nge-PI, i-navigator idala umugqa wokubhekisela ohambisana nomzila esibukweni se-radar, isheshe ithole noma yikuphi ukuphambuka okuseceleni. Lokhu kuwusizo ikakhulukazi ebusuku, emvuleni, noma ekuboneni okulinganiselwe.
Ngaphezu kwe-PI, imikhumbi yesimanje isebenzisa nokulawula umkhondo (isb., i-autopilot esekelwe ku-ECDIS) ukuze igcine umzila. Kodwa-ke, ezindaweni ezivalekile neziminyene, i-autopilot akufanele ithathe indawo yokuqapha kwabantu. Ama-Autopilot kumele ahlale eqashwe futhi elungele ukuthatha izintambo ngesandla.
5. Ukuphathwa kwesivinini kanye nokuma kwebanga
Isivinini esifanele siyingxenye ebalulekile yendlela yokuzulazula. Emanzini amancane:
– Isivinini esiphezulu kakhulu sinciphisa isikhathi sokuphendula futhi sandisa ingozi yokudinga ukubalekela.
– Isivinini esiphansi kakhulu singanciphisa ukulawula ukuqondisa, ikakhulukazi emifudlaneni nasemoyeni.
Umhambi kumele acabangele ibanga lokuma komkhumbi kanye nendawo yokuqondisa etholakalayo ngaphambi kokujika noma ukuhlangana nomunye umkhumbi. Kungcono ukulungisa injini kusenesikhathi, kunokuba kusheshe, ukuqinisekisa ukuthi umkhumbi uhlala uzinzile futhi abasebenzi banesikhathi sokuhlola isimo.
6. Qonda ithonya lemisinga, umoya, kanye "nomphumela wasebhange"
Amanzi amancane avame ukukhulisa izimo ze-hydrodynamic ezingabonakali kakhulu olwandle oluvulekile. Izinto ezintathu okufanele uzilindele:
1. Ukusetha nokuzulazula: ugesi usunduza umkhumbi eceleni (ukusetha) futhi ushintsha isivinini sawo (ukuzulazula). Ukulungiswa kwendlela kumele kwenziwe ngokusekelwe ekubonweni kwangempela, hhayi nje ekulinganisweni.
2. Umphumela webhange: Uma umkhumbi useduze kakhulu nonqenqema lomsele, umfutho wamanzi ozungeze umzimba womkhumbi ungabangela ukuba umphetho usunduzelwe eceleni/udonseleke eceleni, kanti ingemuva lidonseleke onqenqemeni. Lokhu kuyingozi kakhulu emikhunjini emikhulu noma esemifuleni emincane.
3. I-Squat: ukwanda kokudonsa okusebenzayo ngenxa yesivinini emanzini angajulile. I-Squat inganciphisa i-UKC futhi yandise ingozi yokuma komhlaba. Ukunciphisa isivinini ngokuvamile kuyindlela eyinhloko yokunciphisa.
Ukuqonda le miphumela emithathu kusiza umgibeli wemoto ukuthi akhethe indawo esiteshini (hhayi eduze kakhulu nonqenqema), alondoloze isivinini esiphephile, futhi alindele ukulungiswa kokuqondisa.
7. Ukubuka ngamehlo kanye nesiyalo sokubuka
Nakuba ukusebenzisa izinsimbi zesimanje kusiza kakhulu, ukubuka ngamehlo kusabalulekile, ikakhulukazi ku:
- Ukufunda ama-beacons, ama-buoy, izimpawu ezihamba phambili, kanye nemikhakha yokukhanya.
– Ukuhlonza imikhumbi emincane (izikebhe zokudoba, izikebhe zejubane) ngezinye izikhathi ezingabonakali kakhulu ku-radar.
– Hlola izimo zezulu zendawo njengenkungu, imvula enamandla, noma ukukhanya kwelanga okubonakala echwebeni.
Ukubukeka okuhle kunciphisa ingozi yokushayisana futhi kusiza ekwenzeni izinqumo zokuzulazula ngokushesha, ikakhulukazi ngesikhathi sethrafikhi enkulu.
8. Ukuxhumana, i-VTS, kanye nokusetshenziswa kwe-COLREG
Ezindaweni ezimatasa noma eziteshini ezisemachwebeni, ukuxhumana okucacile kungavimbela ukungaqondani. Imikhuba evamile ihlanganisa:
– Bika isikhundla kanye nohlelo lokuhamba ku-VTS uma kudingeka.
– Sebenzisa i-VHF ngempumelelo kodwa uma kudingeka, ngemisho ecacile.
– Qhubeka nokulandela i-COLREG (Imithetho Yomhlaba Wonke Yokuvimbela Ukungqubuzana Olwandle), okuhlanganisa nemithetho emizileni emincane, ukwenqatshelwa kwemikhumbi evimbayo engakwazi ukuhamba ngokuphephile kuphela emizileni, kanye nesibopho sokugcina ibanga eliphephile.
Kodwa-ke, ukuxhumana akufanele kuthathe indawo yemithethonqubo. Izivumelwano zomsakazo ezephula ama-COLREG zingase zidale izingozi zomthetho nezokuphepha.
9. Ukuphathwa Kwezinsizakusebenza Zebhuloho (i-BRM) kanye nokwahlukaniswa kwendima
I-BRM ibalulekile ekuhambeleni okuphumelelayo emanzini amancane. Kudingeka kusetshenziswe izimiso eziningana:
– Ukwaziswa ngaphambi kokungena emanzini amancane: indlela, izingozi, isivinini, izindawo ezibucayi, kanye nezenzo eziphuthumayo.
– Imisebenzi ecacile: ubani okhohlisayo (onikeza imiyalo yenkambo/isivinini), ubani oqapha i-radar/ECDIS, ngubani oqopha futhi oxhumana.
– Inselele kanye nempendulo: isiko lokulungisana uma kukhona ukuphambuka noma ukungabaza.
– Ukulawulwa kokukhathala: kudingeka ukugxilisa ingqondo kakhulu; ukuhlela amashifu kumele kucabangele ukukhathala.
Nge-BRM enhle, ingozi "yokwehluleka okukodwa" iyancipha ngoba izinqumo ziqashwa futhi zisekelwa yithimba.
10. Izinqubo eziphuthumayo: ukubhajwa, ukulahlekelwa yi-steering, ukwehluleka kwenjini
Amanzi amancane awashiyi isikhala esiningi sokwenza izinto ngendlela yokuzilungisa. Ngakho-ke, izinqubo eziphuthumayo kufanele ziqondwe ngaphambi kokungena endaweni, okuhlanganisa:
– Isinyathelo esisheshayo uma kwenzeka ukulahleka kwamandla enjini: lungisa ihange, shayela usizo, yazisa i-VTS.
– Inqubo yomuntu ohamba phezu komkhumbi emigwaqweni emincane nemincane.
– Hlela ukuthi injini izocwila yini: misa injini, hlola ukuvuza, bala ukugeleza kwamanzi, lungiselela izindlela zokunciphisa ngenkathi ubika ngokwenqubo.
Ukuqeqeshwa kanye nohlu lokuhlola kusiza ukuqinisekisa impendulo esheshayo nehlelekile.
I-Penutup
Amasu okuhamba emanzini amancane ahilela inhlanganisela yokuhlela okuningiliziwe, ukuqinisekiswa kwezindawo eziningi, ukulawula isivinini, ukuqonda imiphumela ye-hydrodynamic, kanye nokuxhumana kanye nokusebenza ngokubambisana ebhulohweni. Ezindaweni ezivalekile, amaphutha amancane angaba nemiphumela ebalulekile. Ngakho-ke, isiyalo sokuhamba emanzini—esisekelwa amashadi asesikhathini, ukuqapha okuqhubekayo, kanye ne-BRM eqinile—kuyisisekelo sokuphepha. Ngokusebenzisa njalo lawa masu, imikhumbi ingahamba emanzini amancane ngokuphepha, ngempumelelo, nangokuhambisana nemithethonqubo yokuthumela efanele.
