Kev txhawb nqa tsim rau cov platforms hauv hiav txwv, cov kav dej hauv hiav txwv, cov kav dej hauv hiav txwv, cov phab ntsa dej hiav txwv thiab lub caij no Hauv cov tsev nyob Tide tsis kam, nthwv dej tsis kam, thiab marine corrosion.
5. Kev Tsim Kho Vaj Tse Loj:Cov hauv paus ruaj khov nrog cov ncej dav dav rau cov haujlwm tsim kho vaj tse loj (pas dej, chaw nres tsheb hauv av, thiab qhov av). Kev txhawb nqa rau cov tshuab lag luam thiab cov khoom siv.
1) Chaw Ua Haujlwm Ceg - Kev txhawb nqa hais lus Mev, kev pab tshem tawm kev lis kev cai, thiab lwm yam.
2) Muaj ntau tshaj 5,000 tons ntawm cov khoom hauv Tshuag, nrog ntau yam ntau thiab tsawg
3) Tshawb xyuas los ntawm cov koom haum muaj cai xws li CCIC, SGS, BV, thiab TUV, nrog rau cov ntim khoom seaworthy txheem
1 Ntim:Cov hlau strapping rau kev tuav yooj yim Cov ntoo blocks lossis dunnage raug muab tso rau nruab nrab ntawm cov pawg kom tiv thaiv kev hloov pauv ntawm lub cev thaum nyob hauv cov txheej txheem xa khoom. Kev kho qhov chaw (xaiv tau): Pleev xim dub, roj tiv thaiv xeb, zaj duab xis yas. Cov pawg galvanized kuj tseem tuaj yeem qhwv rau hauv zaj duab xis yas tiv thaiv ib ntus kom tiv thaiv kev khawb qhov chaw. Kev ntim khoom raws li qhov xav tau.
2 Cov Ntaub Ntawv Txog Kev Xa Khoom:Qhov Ntev Txheem Hauv Tshuag: 6m, 12m. Qhov Ntev: tus qauv thiab kev cai. Lawv Los Nrog Hiav Txwv Rail thiab Kev Siv Txoj Kev Haum rau kev thauj mus los hauv hiav txwv, tsheb ciav hlau lossis kev thauj mus los ntawm txoj kev, lawv kuj muaj zog txaus rau kev siv txoj kev. Lub sijhawm xa khoom yog 15-30 hnub tom qab tau txais kev them nyiaj, nyob ntawm seb muaj pes tsawg thiab qhov tshwj xeeb.
