THE NAIVE SAILOR- UNPERFORATED UTI EXTENSION TUBES- CAPT AJIT VADAKAYIL






UTI extension tubes are fitted to cut down the 30 minute moratorium on completion of cargo, before ullaging can commence, on non-inert ships carrying flammable static cargo.




I have served on couple of brand new Japanese SS Chemical tankers, where this extension tube did NOT have any perforation--just 2 air holes on top to let out trapped air.




ON THESE BRAND NEW SHIPS MADE IN JAPAN, I WAS FORCED TO MAKE A SMS REPORT.



No amount of written and detailed verbal explanations could make the Japanese Tech Marine / Engr superintendents , the Shipyard Yard Managers and the Owners understand.




Sometimes ego makes you blind-- or maybe they were plain stupid.

Title *
01G OF 2009 NCO---UTI EXTENSION TUBES PERFORATION

Description *
01G OF 2009 NCO---UTI EXTENSION TUBES PERFORATION All XXX tankers who have UTI tube extensions must have it perforated as required by ISGOTT/ OCIMF.

Otherwise few litres of water can get squirted inside the tube by weight of chemical on top and the bill of lading figure will be wrong—casuing unlimited liabilities.

On XXX UTI pipe extends to tank bottom with entry only at bottom. this creates a situation where vessel is forced to do open ullaging/ sampling as follows--


a) high mp cargoes will freeze inside and will restrict sampler from going down by gravity.


b) source of contamination.


c) ullage for foaming cargoes is not representative of tank content.


d) temperature of UTI is not representative of tank content.


e) with sediment cargoes UTI ullage is not accurate.


f) first foot sample failure can occur due to no fault of ship.


g) the wedge formula used for calculating yard provided ullage tables becomes redundant –as the formula is based on tape assuming vertical position by gravity.


h) certain cargoes like latex can never be loaded , though possible to load by COF and SS resistance tables.


i) few litres of water at tank bottom will be pushed up into non perforated extension pipe by inmixible cargo on top –and UTI readings will indicate full tank of water while the cargo tank actually has negligible water.


wrong bill of lading figures can cause financial disaster.

this perforated arrangement is required on parcel chemical tankers by USCG / port state / CDI / vetting .   a “perforated” extension tube is merely to avoid 30 minutes moratorium for dissipating static charges, in case tank is not inerted.

so either crop the pipe extension into tank or put holes on entire length. CHEMICAL TANKERS WHICH HAVE LATEX IN COF-- CANNOT HAVE A EXTENSION TUBE AT ALL.

    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.

    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.
