Internal was Mr.V V Paul - Sketch navigation lights electrical diagram and explain.. - main engine lubrication I cleared motor general and electrical Thank G☺D Tom Davies Junior function 3(safety) external : a chill guy with beard wearing jeans internal : Paul sir asked so many things bout enclosed space entry... he specificaly wanted to know how would u make sure that ventilation fan is working when you are deep inside the tank... he wanted the answer that you wold put a lock and key arrangment for the fan plug socket and secure it by carrying the key along with you , sounds funny but he told it is the safe practice asked lot bout orb entries, that the formats for the entries in each page, like, he wanted the format for writing date.. the units used... etc, asked me, wher would you enter the incinarated garbage records and in wat unit, the evaporated account of water that we vent out from incinarater service tank keeping the steam open asked a bit bout load lines wat is iccp? function 6(mep) purifier horizontal shaft overhaul steering room bilge pumping out procedure aft seal working indicator card .. thats it from ext paul sir asked me wat is water ingress system and where all it is used A MILLION THANKS TO GOD THAT HE MADE ME CROSS MY MILESTONE HURDLE WITH FLYING COLORS.Thanks to all my friends for helping me to achieve that.Andfinally,words of gratitude to all my teachers and surveyors for passing my all orals with least difficulties.......
