THE NAIVE SAILOR, DAMAGE STABILITY -- CAPT AJIT VADAKAYIL


This post is on popular demand --

Instead of re-inventing the wheel, i will just put an actual email to my company.

You read what follows and everything becomes clear.

Be careful, most inspectors ( PSC / Vetting etc ) who come on board
to test your knowledge on Damage Stabilty are themselves ignoramuses
on this subject.

Subject:  XXXXX/ DAMAGE STABILITY THOUGHTS

gentlemen,

i need to step in - as we are getting paranoid about damage stability --

we do INTACT stability calculations on board merchant ships --  most
important for ships whose cargo can shift -- like copper ore
concentrates and grain.

to prevent grain from shifting -- ship is allowed MOLOO ( more of less
owners option ) by charter party , so that ship can avoid slack holds.

DAMAGE stability comes into play in case ship's hull gets a HOLE due to
an accident/ grounding .

ETAS calculates "survival capabilities" of ship -- if master will tell
them :--

1) where the hole is
2) which all compartments sea water can ingress .

damage stability is NOT like grain loading intact stability calculations
, we do for AMSA and NCB prior loading cargo -- for the WORST 
condition where all slack holds cargo has shifted to its max extent --

on any chemical tanker there will be about 40 load intact CONDITIONS --
as is usual in the ship's stability book.

now--

for each of above CONDITIONS there will be atleast 30 DAMAGE 
CASES --


example -- assumed grounding damage CASES :

case no 1:- bottom raking damage and ingress to forepeak and no 1 cargo
tank port side

case no 15:- side damage at bridge front to no 10 COT port , ballast
pumproom

case no 22:- side and bottom damage to ER ( with permeability ) and HO
tank port

case no 29:- bottom damage to after peak tank , and steering gear.

etc etc


this amounts to several hundreds of permutations and combinations for a
ship without a class approved damage stability programme in the
loadicator -- 

for damage stability ballast conditions are NOT considered.

this info is what we send to Class ETAS after every dep load port--with
permeability's .  for ETAS to use their software and calculate :--

1)residual dynamical stability ( area under curve > 0.0175 m rad )

2)righting lever range ( min range 20 deg beyond posn of equilibrium
plus GZ >0.1 mtrs within 20 deg range )

3)max angle of heel due to unsymmetrical flooding ( < 25 deg or 30 deg
in case no deck immersion happens )-- and assess survival capabilities
and give advise.

ONLY WHEN THE HULL GETS A HOLE -- read this twice-- 
ONLY WHEN THE HULL GETS A HOLE --

if you insist to Class that you want damage stability calculations ,
without a hole -- this will be greatest joke of the century for them --
they will have a nice laugh over saki and sushi--

we stick to approved loading patterns or CONDITIONS given in the
stability book-- on usual ships --but NOT parcel tankers.


ON "PARCEL" TANKERS --

AAA) WE ARE CAREFUL WHEN THE CARGO IS OF VERY HIGH 
DENSITY -- GREATER THAN DENSITY 1.7 .

i had once carried dead sea drilling brine salts of > 2.0 density for
XXXX --if you are NOT careful ship will capsize or even
break her tanks during rolling.

BBB) WHEN TOO MUST CARGO IS LOADED TO ONE SIDE OF 
THE CENTRE LINE -- THAT WE DO NOT HAVE ANY
POSSIBILITY TO CORRECT THE LIST WITH BALLAST ,
AS ALL COUNTERACTING BALLAST TANKS ARE ALREADY 
USED UP.  AND YOU CANT EVEN JETTISON CARGO DUE 
TO ITS NATURE--

this is the reason why in the stowage plan attached-- i PERSONALLY check
out the LIST created by cargo-- to caution the mate-- when he gets it
all wrong due to tunnel vision.


having said all this -- the botttom line is -- you need a blessed hole
to DAMAGE an INTACT ship.

    Respected Captain,

    What is special about Tamil Nadu?

    How come it is able to continuously produce word geniuses like Ramanujam, Subrahmanyan Chandrasekhar, C.V. Raman, A.R. Rahman, Abdul Kalam, Venkatraman Ramakrishnan, Viswanathan Anand, Illayaraja, etc?

    Even till recently the Chief Justice of India, the Finance Minister, the RBI governor are all Tamils?

    Is there any scientific reason behind this? Because no other region has produced such super genius people in such numbers.

    Regards

    hi ch,

    i am sure if i were a lawyer, i will NEVER EVER become CJI.

    i am sure if i were an economist, i will NEVER EVER become finance minister.

    you want me to continue ?

    when i was on my training ship in mumbai with 250 other cadets ( two years ) -- the biggest TELUs ( oily and slimy ) and SNEAKS ( snitches ) became SCC ( senior cadet captains ) , CC ( cadet captains ) , CL ( cadet leaders ) etc.

    i used to be in the CAPTAINS MONTHLY BREAKFAST PARTY ( cadet with maximum negative marks for OFFICER LIKE QUALITIES ) -- to be chewed up for breakfast every month .

    i got an EXTRA FIRST in every subject --except OFFICER LIKE QUALITIES.

    now what are OFFICER LIKE QUALITIES-

    being a son of a bit#h, being a sneak, being a hypocrite, being a as$ kisser , being a leader who will sell out his team, being a back biter, being an informer , being the best in playing to the gallery.

    so, so--

    at the passing out parade --most of the cadets who got all PRIXES were leaders -- they all got BOOOOOEEEEED !

    I remember i got only one prize--for being the best REPORTER IN ENGLISH -- the claps I got from the entire hall still resound in my ears -- along with another ROC ( royal officer cadet -who did NOT care to become a sold out leader ).

    and mind you -- i was in every single team which made my TOP ( starboard fore top ) the champion TOP.

    i was a champion sailor, rower, signaller, marks in subjects, soccer team in both years --

    but i lacked OLQ ( officer like qualities ) of being a FU#KIN' SLIME BALL.

    so in my passing our certificate , after two years of training -- i had an EXTRA FIRST in all subjects -- except OLQ where i was third grade

    so i guess they held a special meeting and GRACED ME TO FIRST CLASS --a young 18 year old boy -- .TEE HEEE !

    AT SEA, THE SAILORS DO NOT CARE FOR YOUR FOUR STRIPES- THEY ONLY CARE FOR WHO YOU ARE--

    AT SEA PEOPLE WHO KNOW ME , OR HAVE HEARD OF ME -- OR SAILED WITH ME, WILL VOUCH--

    CAPT AJIT VADAKAYIL WAS A SLAVE MORE POWERFUL THAN THE MIGHTY FU#KIN' CAESAR -- BY LIGHT YEARS .

    this has now passed on to LORE -- never ti happen again in the annals of sea .

    am i boasting ?

    -- so be it !

    humility is NOT about having a low opinion of yourselves to please the JEALOUS party.

    see, this would have been part of my post-- GAMES CAPTAIN PLAYED--

    you made me reveal it prematurely --with your TAMIL PRIDE ! TAKE IT EASY !

    check out my training ship-

    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.

  4. What is the purpose of inclining experiment before delivery of ship or any modification?

    1. hi bs,

      i do not take such questions--

      however-

      INCLINING EXPERIMENT IS TO FIND KG.

      If any weight is shifted on board a vessel, the center of gravity of the vessel will shift in a direction parallel to the weight movement.

      The distance G moves is found by the formulas:
      1.GG' = (w x d) / Displ.
      2. tan (angle of list) = GG'/ GM
      3. GG' = GM tan (angle of list) [transposing equation (2.)]
      4. GM tan (angle of list) = (w x d) / Displ. [(setting equation (3.) equal to (1.)]
      5. GM = (w x d) / (Displ.)(tan (angle of list)

      To find KG of the light ship you need to subtract GM from KM.

      All extraneous weights onboard the vessel at the time of the inclining test will need to be located and identified so they can be removed by using a weighted average calculation.

    hi is,

    https://www.youtube.com/watch?v=0KMVhb57RqI

    CHECK OUT THE VIDEO ABOVE.

    THE LAST CONGRESSMAN ON HIS FEET IS FUCKED. VIDEOS MONITOR .

    THE FASTEST ON THEIR FEET ARE REWARDED .

    THE SLOWEST ON THEIR FEET WILL GET ELIMINATED POLITICALLY AND HOUNDED .

    I once went for briefing to a Zionist Jew owned shipping company HO at London.

    Suddenly i head a bell and all top directors/ managers literally left their seats in the huge single hall and ran towards the conference room .

    The GM of chemical tankers who was briefing me , dropped everything midway and ran.

    I asked a Latvian Captain -- what the fuck is going on?

    Is there some emergency or a fire ?

    he spAke: THE TOP JEW OF THIS OFFICE HAS PRESSED THAT ALARM BELL. IT IS THE CALL FOR A NON-ROUTINE MEETING. THE LAST ENGLISHMAN IN, IS FUCKED . HE WILL BE SHOUTED AT AND THEN FINGERED. AND IF HE CONSISTENTLY IS THE LAST MAN IN, HE WILL BE SACKED. . .THIS IS REAL MODERN SLAVERY IN THE HEART OF LONDON.

    I have witnessed a sacking in this office.

    a top british manager was next to me. the Jew top honcho comes out screams at him , tells him he is sacked-- tells him, to leave the office within 60 seconds.

    this white man literally ran out of the office, and the next day he was in brazil.

    every top Jew in shipping is also attached to a vicious mafia and a vicious team of lawyers.

    Finally when i joined the ship my first message was-- I REFUSE TO WEAR MY UNIFORM AND PEAK CAP, MY WIFE HAS SO THOUGHTFULLY PACKED UP FOR ME- THIS COMPANY DOES NOT DESERVE ME IN UNIFORM . .

    every single day i used to send messages full of shit ( with a pearl packed inside ).

    they dived into the shit daily to retrieve the pearl.

    i pointed out the deadly technical mistakes in their signed company circulars --with such HUGE mistakes the company can be sued and it will come down.

    finally I reached home --i told my wife -- i dont plan to join back this slave company--

    a week later ,i get a call from the mumbai office--congratulations you have been given the highest bonus ever.

    then my wife said-- either you return the bonus or do one more ship.

    i did one more ship.

    half way through , i resigned quoting PERSONAL POLICY-- my ship was a houston loading horse tallow for nigeria.

    i said , i do NOT go to nigeria. you have a company policy- i have mine too.

    they let me go from houston.

    FIRST THING TO SALVAGE THE PATHETIC INDIAN NAVY IS TO CHANGE TO COLOUR OF THEIR UNIFORM FROM WHITE TO KHAKHI

    ALL RESPONSIBLE PEOPLE INCLUDING THE CAPTAIN MUST BE SACKED

    THIS IS SHEER INCOMPETENCE

    I REMEMBER --AS A YOUNG 25 YEAR OLD CHIEF OFFICER, I DID A DRYDOCK MANOEVERE OF A HIGHLY UNSTABLE SHIP , AT HAMBURG -- FIRST TIME ON THE PLANET

    http://ajitvadakayil.blogspot.in/2011/08/india-stands-tall-capt-ajit-vadakayil.html

    AGAIN-- SACK ALL RESPONSIBLE

    THIS IS THE HEIGHT OF INCOMPETENCE

    ARE OUR INDIAN NAVY CAPTAINS INCOMPETENT?
