Q1: Dab tsi yog qhov tseem ceeb sib txawv ntawm onshore thiab offshore kab kav dej?
A1:Offshore cov kav dej ntsej muag tau ntsuas siab dua, cov khoom siv hluav taws xob zoo nkauj, thiab xeb (seawater). Lawv yuav tsum tau tuab phab ntsa, zoo tshaj qub (3LPP), thiab nkees-resistant cov ntaub ntawv. Cov txheej txheem kev teeb tsa sib txawv (s-nteg thiab trenching).
Q2: Npaum li cas cov raj xa dej ruaj khov rau ntawm lub seabed?
A2:Cov pob zeb ua qhov hnyav (CWC) muab cov buotyancy tsis zoo. Daim txaj txaj lossis pob zeb pov tseg tiv thaiv kev txav mus los. Kev siv tsis pub dhau los siv cov kev txhawb nqa lossis hnab ntawv khau khiab.
Q3: Dab tsi yog cov yeeb nkab-hauv-yeeb (PIP)?
A3:Pip puas muaj cov cab hlau sab hauv thiab txheej txheem txheej txheem sab nraud nrog rwb thaiv tsev (piv txwv li, ua npuas ncauj). Siv rau high-kub flowlines (piv txwv li, roj deepwater). Lub ann annatus yuav muaj nitrogen rau rwb thaiv tsev thermal.
Q4: Cov kev pheej hmoo ntawm kev tshaj tawm dawb hauv kev xa khoom dawb hauv Isesea?
A4:Dawb Spans vibrate los ntawm cov dej khov, ua rau qaug zog. Vortex-induced tshee (VIV) tuaj yeem ua rau tsis ua haujlwm. Kev kho kev ncua feem ntau yuav cuam tshuam nrog kev txhawb nqa lossis kev ua seedbed.
Q5: Yuav ua li cas yog corrosion tswj nyob rau hauv ntug dej hiav txwv?
A5:Cov Tswv Yim Ua ke:
Kev fij tau tus anodes nrog txheej txheej
Ua kom zoo cp rau loj system
Li niaj zaus ROV kev kuaj xyuas
Kev txhaj tshuaj biocide rau mic
