Salamalejkum 2 i hope this will help you .
Doha ATC will activate LVP when VIS is below 1200m which also mean separation should be increased from standard radar 5 NM to 12 NM.
For instance AUH will rise LVP even on VIS 2000m its up to airport ATC .
F/O can take off and land even if LVP is in force as long as you have :
RVR above 600 m
Cloud base 200ft or above
Wind CWC less 15kt
and its not CAT C
You can take 30 min fuel for LVP becouse you can expect delay in taxi and take off clereance due to separation 12 NM
