Cov iav loj loj ua lub luag haujlwm tseem ceeb hauv kev siv hauv dej hiav txwv, muab kev ua haujlwm zoo tshaj plaws thiab kev ruaj khov hauv ntau lub tshuab dej hiav txwv. Cov iav no yog tus cwj pwm los ntawm lawv cov hniav uas nkhaus, uas tso cai rau kev sib koom tes du thiab txo suab nrov, ua rau lawv zoo tagnrho rau cov chaw nyob hauv dej hiav txwv uas kev ntseeg siab yog qhov tseem ceeb.

Ib qho ntawm cov ntawv thov tseem ceeb ntawm cov iav loj helical hauv kev lag luam marine yog nyob rau hauv cov txheej txheem propulsion. Lawv siv rau hauv cov gearboxes ntawm cov nkoj thiab submarines, hloov lub zog cav mus rau hauv lub zog tig uas xav tau los thawb cov nkoj hla dej. Lub peev xwm ntawm cov iav helical los tswj cov khoom thauj siab thaum tswj kev ua haujlwm du ua rau muaj kev ua tau zoo thiab kev ntseeg siab ntawm cov nkoj marine no.

Tsis tas li ntawd xwb, cov iav loj helical feem ntau pom muaj nyob rau hauv winches thiab hoists, qhov tseem ceeb rau kev ua haujlwm docking thiab kev thauj khoom. Lawv txoj kev tsim qauv ruaj khov ua kom lawv tuaj yeem tswj hwm cov khoom hnyav thiab tiv taus kev hnav, uas yog qhov tseem ceeb hauv cov xwm txheej marine hnyav. Qhov kev ntseeg siab no txo ​​qis lub sijhawm tsis ua haujlwm thiab cov nqi txij nkawm, ua rau lawv yog qhov kev xaiv zoo rau cov neeg tsim nkoj thiab cov neeg ua haujlwm.

Hauv cov ntsiab lus ntawm cov tshuab drilling hauv hiav txwv, cov iav helical loj yog qhov tseem ceeb rau ntau yam tshuab, suav nrog cov khoom siv drilling thiab lifting. Lawv qhov kev ua haujlwm zoo pab ua kom zoo dua cov txheej txheem extraction, xyuas kom meej tias kev siv hluav taws xob tsawg kawg nkaus thaum ua kom muaj txiaj ntsig zoo tshaj plaws.

Zuag qhia tag nrho, cov iav loj helical yog qhov tseem ceeb hauv kev lag luam marine, muab lub zog, kev ua haujlwm zoo, thiab lub neej ntev. Raws li thev naus laus zis nce qib, lawv lub luag haujlwm yuav nthuav dav, txhim kho kev ua haujlwm marine ntxiv thiab pab txhawb rau kev nyab xeeb dua, kev ua haujlwm marine zoo dua.
