THE ABOVE 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

IT SHOWS THE PROACTIVE AND MULTI-TASKING NATURE OF CHEMICAL 
TANKER SHIPBOARD MANAGEMENT. 

A CHEMICAL TANKER 3/4 STRIPER CANNOT BE A HALF-WIT.

  1. hi Capt.

    can you explain to me some terms you used such as :
    SOF
    LOP
    mentioned in DISCHARGE ( ON COMPLETION) CHECKLIST ?

    thanks in advance

    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.

    punch into Google search-
    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.

    hi sk,

    WHY WAS CAPT AJIT VADAKAYIL THE MOST POWERFUL SHIP CAPTAIN AT SEA?

    WHY WERE HIS BOSSES MORTALLY SCARED OF HIM?

    WHY WAS THIS SHIP CAPTAIN LIKE THE "SLAVE MORE POWERFUL THAN CAESAR "?

    OK-- THE EASY WAY OUT IS TO SAY THAT THIS CAPTAIN KNEW MORE THAN OTHERS .

    SORRY-- THE COOKIE DOES NOT CRUMBLE THAT WAY.

    I KNEW MY POWERS VESTED IN ME BY THE PRESIDENT OF INDIA BY A DOCUMENT--THE MERCHANT SHIPPING ACT.

    http://vikaspedia.in/social-welfare/unorganised-sector-1/the-merchant-shipping-act1958

    I ONCE HAD A BOOS WHO SAILED ON MY SHIP FOR 2 DAYS .

    FROM HOUR ONE HE WAS AFTER MY ASS -TRYING TO TEAR IT APART.

    I ASKED MY PURSER TO SIGN HIM ON ON THE SHIPS" ARTICLES OF AGREEMENT"

    LEGALLY AT SEA THERE CAN BE NO PASSENGERS ON A MERCHANT SHIP WITHOUT PROPER DOCUMENTS.

    HE REFUSED TO SIGN IT- SAYING THAT HE HAD NEVER DONE IT BEFORE.

    IMMEDIATELY I TOLD THE PURSER AND CHIEF OFFICER -- YOU ARE WITNESS , CARRY ON.

    THIS MANGY BOSS WENT RUNNING AFTER THE PURSER AND SIGNED IT-- AND NOW HE WAS PART OF MY CREW.

    SO I TOLD HIM--

    AT NEXT PORT I WILL SIGN OFF MY CHIEF ENGINEER AND I WILL ASK THAT YOU BE MADE MY CHIEF ENGINEER TILL I GET A SUITABLE REPLACEMENT.

    ( THOSE DAYS I WAS THE BLUE EYED BOY )

    YOU SHOULD HAVE SEEN HIS FACE --HE LITERALLY SHAT AS WE COULD SMELL SHIT.

    ALWAYS KNOW YOUR POWERS.

    THE INDIAN PRESIDENT MUST KNOW HIS POWERS.

    DID NOT TN SESHAN ( ELECTION COMMISSIONER ) POONGI BHAJAO ALL THE HIGH AND MIGHTY POLITICIANS ? SAB KA GAAAN EKKATTA PHAAD DIYA . .

    THEY WERE ALL CRYING MUMMMMYYYYY !

    HE KNEW HIS POWERS.

    IF TN SESHAN WAS PRESIDENT -- THE FUTURE PRESIDENTS WOULD HAVE BEEN ON A BETTER WICKET.

    when i wanted to interpret the merchant shipping act--i would call my wife and ask her to think like a landlubber ( like a lawyer in a court of law ) .

    see, i would be tied down by PRE-CONCEIVED NOTIONS.

    at sea i tool officers and crew who had NIL chemical experience and I moulded them like RAW CLAY.

    dog's tail cant be straightened !

  6. Hi Capt,

    i would like to check when the ship is in port, what are the emergency informations which is available to shore rescue agencies and where are these information found?

    thank you!
