THE FOLLOWING SERVES AS A “MEMORY JOGGER" FOR A 3/4 STRIPER ON A
PARCEL CHEMICAL TANKER , RATHER THAN A CHECK LIST—AND IS BY
NO MEANS COMPREHENSIVE.
IT SHOWS THE PROACTIVE AND MULTI-TASKING NATURE OF CHEMICAL
TANKER SHIPBOARD MANAGEMENT.
A CHEMICAL TANKER 3/4 STRIPER CANNOT BE A HALF-WIT.

thanks for information
ReplyDeleteit helped me a lot
but i have a question
how the pipe lines are cleaned ?
hi mahmoud,
ReplyDeletethe same stripped bottom content while tankwashing , ( water/ solvent/ hot water ) --is used to flush the lines , drops and manifolds ( both sides ) .
finally lines are steamed from the p/s manifolds into tanks , via drop and pump --with steam alloawed to escape from PV vacuum side.

STOP PRESS:
I AM WRITING THIS AS I PROMISED ONE OF MY READERS 45 MINUTES AGO-- HE RAN UP TO ME DURING MY MORNING WALK--
HE WANTED TO KNOW OUT OF MY 300 PLUS SCOOPS IN MY NEARLY 845 ODD POSTS--WHICH IS NO 1 AND WHICH IS NUMBER 300.
############
well let me make it clear , these 300 scoops are CONSTRUCTIVE SCOOPS .
all these 300 scoops are in the plane of INVENTION and NOT innovation.
none of these 300 scoops are DESTRUCTIVE -- so my posts proving that edison, newton, darwin, einstein etc are IDIOTS does not find a place in these scoops.
so waht could be the no 1 scoop?
it is about providing a HINT on how to make a astronaut hibernate while travelling to mars -to cut down on food and water .
it is about keeping alive a seriously wounded soldier till he can find proper medical care.

HIBERNATION WITH HYDROGEN SULPHIDE GAS VADAKAYIL
and
FUMAROLES FOR FREE ENERGY AND HYDROGEN SULPHIDE SUICIDES IN JAPAN VADAKAYIL
one of my russian chief engineers who lived near siberia , a place infested with HUGE bears had once woken up a bear while on hibernation in a cave ( as a child ) and he told be how furious the animal was. Before they go into months of hibernation they would kill a large animal ( bury the dead animal it in the ground ) and would NOT eat it unless it became putrid , reeking of rotten eggs..
WELL WHAT WOULD BE NO 300 RANK.
it is about PIN WORMS on as$hole.
Check out the comment dated 18th Dec 2013 , about surcharging the anus with oxygen 5 times a day to prevent pinworms disrupting your REM sleep. This is a 6000 year old Ayurvedic cure for pinworm which happens when you eat non-veg heavy meats and do NOT wash your as$hole after a crap.

VEDIC PRACTISES IN MECCA VADAKAYIL
If I were a white JEW, I would have been an international celebrity. but then who cares?
I have reached a stage where ONLY I can evaluate myself--
one of my DUTCH bosses tried to patronise me nearly 2 decades ago -- he said he has given me a good confidential service report-
so i told him something in Hindi -- with its translation.
VADAKAYIL KHUD QUESTION PAPER SET KARTA HAI !
VADAKAYIL KUD EXAM LIKTHA HAI !!
VADAKAYIL KHUD NUMBER DETA HAI !!!
capt ajit vadakayil sets his own exam question paper, he writes the exam , and then he gives himself the marks .
THIS IS THE MEANING OF LIBERATION.
believe me -- that man hugged me ( NO patronising here ) and said -- he expected such an frank retort from me .
he said- every other captain would have said thank you .
he was told to enter into this dialogue by the single man owner of that shipping company . this was about my " CUT THE CRAP " EMAILS -- where i would point out that the EMPEROR IS NAKED .
99% of the people will NOT even understand the wisdom and gravity of the statement above.
