1. Lng Carriers: Txhim Kho Cov Khoom Noj Uas Muaj Khoom Noj & Roj Kev Nyab Xeeb
DNV imposes strict tsim qauv thiab kev ua haujlwm rau Lng Carriers vim yog cryogenic phom sij thiab boil-off roj (bog) tswj hwm. Qhov tseem ceeb yuav tsum muaj xws li:
Hom C Tank Faultification: Kev tso tsheb hlau luam ywj siab prematic yuav tsum tau sim siab thiab ntsuas kev ntxhov siab hauv DNV cov cai.
Bog tuav lub tshuab: cov nroj tsuag rov qab lossis roj sib txuas ua ke yuav tsum ua raws li IGF code (tus lej thoob ntiaj teb rau roj).
Kev Tshawb Nrhiav Kev Kub Ntxhov & ESD): Sensors yuav tsum saib methane dej hauv cov chaw cargo, nrog cov roj cev cais.
Cov Txheej Txheem Txuas Ntxiv: Hull ntxiv dag zog rau sloshing loads hauv ib nrab ntim chaw tso tsheb hlau luam, ib DNV's Sloshing Refore Lus Cim.
Crew Kev Kawm: Kev cob qhia EGF txoj kev kawm rau cov neeg ua haujlwm Lng kev ua haujlwm.
Cov kev ntsuas no ua kom muaj kev thauj khoom nyab ntawm lng ntawm -162℃thaum ntsuas kev pheej hmoo tawg.
2. Cruise nkoj: Hluav Taws Kub Kev Nyab Xeeb & Kev Tawm Tsam
DNV's Neeg Caij Npav Cov Ntawv Qhia Kev Nyab Xeeb Kev Nyab Xeeb Siv Kev Tiv Thaiv Hluav Taws Kub thiab Kev Khiav Tawm Rau Cruise Nkoj Nqa Ntau Txhiab:
Hluav Taws Kub Zone Qhov Contactionization: "A-60" kev faib tawm chav kawm nrog cov pa luam yeeb nrhiav kom tau hauv txhua txoj kev hauv kev thiab cabins.
Kev Tawm Tsam Tawm Tsam Kev Ua Si: RoonBoot thiab Lifeft thiab Lifefts yuav tsum haum 125% ntawm cov neeg caij tsheb, nrog cov chaw nres tsheb mus ze.
Tsev Kho Mob & Thaj Chaw Nyab Xeeb: Redundant Fais Fab thiab Kev Kho Mob ua tau raws li Solas tshooj II-2.
Kev sib sau ua ke hauv thaj chaw Cyberigity: Cov neeg sib xyaw ua ke yuav tsum tawm tsam hacking nyob rau hauv cyber kev ruaj ntseg sau npe.
Huv Si & Khib Khov Tawm Tsam: Ua raws li Mepc.227 (64) kom tiv thaiv kev ua qias tuaj hauv thaj chaw rhiab.
Cov kev cai no ua rau cov neeg caij nrog cov neeg caij muaj kev muaj sia nyob hauv kev kub ntxhov.
3. Lng Carriers: Redundant Inpulsion & Fais fab Systems
Txhawm rau tiv thaiv kev puas tsuaj ntawm cov neeg soj ntsuam-qhov tseem ceeb rau LN Carriers ze Populated ntug dej hiav txwv-DNV yuam kev:
Dual-roj cav rov ua dua tshiab: tsawg kawg yog ob lub tshuab ywj siab rau kuv-GI lossis X-DF cav.
Backup Power Tiam: Cov Generator Thaum Xwm Ceev yuav tsum tau rov ua haujlwm nyob rau hauv 45 vib nas this ntawm blackout.
Roj teeb hybrid Systems: xaiv roj teeb kev nyab xeeb rau cov nkoj uas siv Lithium-ion backups.
Khoom Siv Roj Roj (FGSS): redundant piping thiab vaporizers kom ntseeg tau tias tsis tu ncua lng ntws.
Dynamic txoj hauj lwm (DP): Rau FSRUS (Floating cia Unleasification koog), DP chav kawm 2/3 yog yuav tsum tau.
Qhov no minimizes drift txaus ntshai thaum LNG hloov kev ua haujlwm.
4. Cruise nkoj: Suab & Kev Tswj Kev Co
DNV cov kev nplij siab chav kawm paub ua kom ua kom muaj kev pab dua cov neeg muaj kev tswj hwm muaj khoom kim heev:
Cabin cov suab nrov qib: tsawg dua lossis sib npaug ntawm 35 DB (a) hauv staterooms, tsawg dua lossis sib npaug zos (ib ISO 6954).
Kev co Damping: Chav nyob ruaj ruaj nyob nrog resilient mounts los txo cov qauv kev vibrations.
HVAC Optimization: Airflow suab nrov tswj nyob rau hauv cua rauv.
Underwater suab nrov nrov (Urn): Ua raws li DNV uas tsis muaj kev tiv thaiv kev tiv thaiv tub rog lub neej.
Stabilizer Performance: Nquag Xov Xwm Lub Tshuab kom txo qis cov lus tsa suab (< 2° RMS in moderate seas).
Cov qauv no tseem ceeb rau cov neeg ua haujlwm lub nkoj siab zoo li kev sib tw lossis cov huab tais caribbean.
5. LNG Carrers & Cruise nkoj: Lwm Cov Roj Kev Pom Roj
DNV cov roj teeb npaj npaj npaj cov hlab rau yav tom ntej ammonia, hydrogen, lossis methanol saws me nyuam:
Lng Carriers: Tsim Pom Zoo rau Ammonia Dual-Roj Retrofits, suav nrog Tank Hloov kho thiab NH3-tshaj cov khoom siv NH3.
Cruise nkoj: hydrogen cia cov kev tshawb fawb, nrog tawg-pov thawj roj ntawm chav.
Roj System nyem: Pipelines thiab Bunker cov chaw nres tsheb hloov tau rau ntau tus roj.
Cov Crew Kev Txawj Ntse: Kev cob qhia cov kev cai rau cov roj sib txuas.
Emissions kev ua raws cai: Kev pov thawj ua ntej rau xoom-emission npaj npaj qauv.
