Cov Lus Qhia Tseem Ceeb rau GMDSS & Cov Cuab Yeej Siv Nkoj ntawm Seagoing Vessels
Cov Lus Qhia Tseem Ceeb rau GMDSS & Cov Cuab Yeej Siv Nkoj ntawm Seagoing Vessels
Rau cov nkoj hiav txwv thoob ntiaj teb, ua raws li qhov yuav tsum tau ua GMDSS (Lub Ntiaj Teb Maritime Kev Nyuaj Siab thiab Kev Nyab Xeeb Kev Nyab Xeeb) thiab cov khoom siv kev taw qhia tsis yog - sib tham tau - nws cuam tshuam ncaj qha rau kev nyab xeeb hauv hiav txwv, kev ua raws cai, thiab Port State Control (PSC) cov nqi kuaj xyuas. Phau ntawv qhia no qhia txog cov kev cai tseem ceeb rau ob lub tshuab, ua raws li qhov tseebInternational Voyage Ship Txoj Cai Kev Ntsuam Xyuas Cov Cai (2024), SOLAS Tshooj IV thiab V, IMO daws teeb meem, thiab IEC cov qauv. Nws pab cov tswv nkoj, pab pawg neeg ua haujlwm hauv hiav txwv, thiab cov kws tshaj lij kev muag khoom kom ua tiav tag nrho thiab xaiv cov cuab yeej tsim nyog rau kev taug qab dej hiav txwv thoob ntiaj teb.
GMDSS thiab navigation systems yog ib qho tseem ceeb rau kev nyab xeeb hauv hiav txwv: GMDSS ua kom muaj kev ceeb toom kev ntxhov siab thiab kev sib txuas lus thaum muaj xwm txheej ceev, thaum cov khoom siv navigation muab qhov tseeb qhov chaw, tiv thaiv kev sib tsoo, thiab kev paub txog xwm txheej. Kev nkag siab txog cov kev cai tseem ceeb no yog qhov tseem ceeb kom tsis txhob raug kaw, raug nplua, thiab kev pheej hmoo ntawm kev nyab xeeb.
1. Cov Txheej Txheem Txheej Txheem Txheej Txheem: Lub hauv paus ntawm Kev Ua Raws Cai
Txhua qhov yuav tsum tau ua hauv qab no yog ua raws li cov kev cai thoob ntiaj teb maritime conventions thiab cov qauv, tswj los ntawm tus chij xeev thiab PSC cov tub ceev xwm. Cov ntaub ntawv tseem ceeb muaj xws li:
SOLAS Tshooj IV: Muab GMDSS cov cuab yeej siv, kev ua haujlwm, thiab kev ua haujlwm.
SOLAS Tshooj V: Txhais cov cuab yeej siv taug kev uas yuav tsum tau ua rau txhua lub nkoj hla thoob ntiaj teb.
International Voyage Ship Statutory Inspection Technical Rules (2024): Txhais cov rooj sib tham thoob ntiaj teb rau hauv cov kev xav tau.
IMO Resolutions (piv txwv li, MSC.74(69), A.819(19)): Qhia cov qauv kev ua tau zoo rau GMDSS thiab cov khoom siv navigation.
IEC Cov Qauv (piv txwv li, IEC 60945, IEC 61108): Tswj kev hloov pauv ib puag ncig, kev ua haujlwm, thiab kev sim ntawm marine electronics.
Tsis yog-kev ua raws cai tuaj yeem ua rau PSC raug kaw, nkoj hauv av, lossis kev lav phib xaub raug cai- tso cai rau cov cuab yeej ua ntej uas ua tau raws li lossis tshaj cov qauv no.
2. Cov Lus Qhia Tseem Ceeb rau GMDSS Cov Khoom Siv
GMDSS ua kom ntseeg tau tias muaj kev ceeb toom kev ntxhov siab, kev sib txuas lus thaum muaj xwm txheej ceev, thiab cov ntaub ntawv kev nyab xeeb sib faib thoob plaws txhua thaj chaw hiav txwv. Cov kev xav tau sib txawv ntawm lub nkoj ua haujlwm hauv hiav txwv (A1-A4), tab sis cov cai tseem ceeb siv rau txhua lub nkoj hiav txwv thoob ntiaj teb.
2.1 Sea Area Classification & Cov khoom siv sib xws
GMDSS cov cuab yeej yog tsim rau plaub thaj chaw hiav txwv (txhais los ntawm xov tooj cua kev pab). Cov nkoj yuav tsum tau nruab raws li thaj chaw hiav txwv deb tshaj plaws uas lawv ua haujlwm hauv:
Hiav txwv A1(Hauv 20 nautical mais ntawm ntug dej, VHF kev pab them nqi):VHF DSC xov tooj cua(CH 16 rau kev nyuaj siab, CH 70 rau DSC saib), 406 MHz EPIRB, SART, thiab lifeboat ob -txoj kev VHF xov tooj cua.
Hiav txwv A2(Hauv 150 nautical mais ntawm ntug dej hiav txwv, MF kev pab them nqi): A1 khoom + MF DSC xov tooj cua (2187.5 kHz rau kev ntxhov siab).
Hiav txwv A3(150 nautical mais mus rau 70℃N/S, INMARSAT kev pab them nqi): A2 khoom + satellite kev sib txuas lus (INMARSAT) rau kev ceeb toom kev ntxhov siab.
Hiav txwv A4(Tshaj A3, suav nrog thaj tsam polar): A3 cov khoom siv + HF DSC xov tooj cua (4, 6, 8, 12, 16 kHz) rau ntev -kev sib txuas lus muaj kev ntxhov siab.
2.2 Yuav tsum tau GMDSS Khoom Nta & Ua raws
Tag nrho cov khoom siv GMDSS yuav tsum ua kom tau raws li cov kev cai tseem ceeb no, tsis hais thaj tsam ntawm hiav txwv:
Kev ceeb toom kev nyuaj siab: Xa / tau txais kev ceeb toom kev ntxhov siab manually lossis txiav (xws li, dej- qhib EPIRB), suav nrog GNSS cov ntaub ntawv txoj haujlwm.
Hom kev pom zoo: Tuav daim ntawv pov thawj siv tau los ntawm cov koom haum uas tau lees paub (CCS, DNV-GL, EC, FCC) los ua pov thawj ua raws li IMO/IEC cov qauv.

GMDSS / navigation khoom tsis koom nrog GNSS lossis onboard systems.
Kev kho tsis tiav / tsis tiav, calibration, lossis cov ntaub ntawv xeem.
Cov neeg ua haujlwm tsis tau kawm rau GMDSS / navigation cov cuab yeej ua haujlwm.
5. Xaus: Ua kom muaj kev nyab xeeb, ua raws li kev ua haujlwm
Kev sib ntsib GMDSS thiab cov khoom siv kev taw qhia yog qhov tseem ceeb rau lub nkoj, neeg coob, thiab kev nyab xeeb ntawm cov khoom thauj. Kev sib xyaw cov khoom siv xaiv thiab kev ua haujlwm nrog SOLAS, IMO, thiab IEC cov qauv pab kom tsis txhob muaj kev nplua, txhim kho kev paub txog qhov xwm txheej, thiab ua kom muaj kev ntseeg siab hauv thaj chaw hauv hiav txwv hnyav.
Kev koom tes nrog ib tus neeg muag khoom siv hluav taws xob marine ntseeg tau yog qhov tseem ceeb. Ib tus neeg muag khoom ntseeg tau muab hom- cov cuab yeej pom zoo, ntxiv rau kev teeb tsa, ntsuas qhov ntsuas, kev cob qhia, thiab tom qab- kev muag khoom txhawb nqa kom txo qis qis thiab ua kom ntev - ua raws sijhawm.
