THE NAIVE SAILOR , WINCH BRAKE RENDERING-- CAPT AJIT VADAKAYIL


On one of my ships, i received a general circular from the company , that the bow stopper must NOT be put after anchoring, and that ship should put a red flag on the gypsy--so that -- hold your breath-- the wheelhouse OOW can come to know when the windlass brake renders ( SIC!!).

They went on and on in about 18 pages to warn us that if we don't do that, the anchor chain will snap!. And they made a nice video to back their claim. The stupid video had more video graphic content that seamanship content, and it would WOW a retarded 8 year old.   It was amusing to see the anchor cable moving like an anaconda, disregarding the damping effects of seawater and force of gravity.

I wasted no time in being most sarcastic , ( you should never be civil to fools who put sailors lives in danger even if he is related to the almighty queen ) and telling them that the red flag was first introduced to the blue high seas in 1992 by the Russian bunker river operating  barge pretenders who came out to sea with forged certificates.

I declared categorically that i would NOT follow this bullshit (with a capital B ) circular, nor will anybody at sea--and that all the ship staff is already sniggering over this fantastic circular, written by the stupid DPA.

I myself have done thousands of anchorings over 28 years in command with,  100% success rate , on different types of ships , in different locations, in different weather conditions--unlike pilots who are one trick ponies.

Rendering can be tolerated for static braking like the mooring hawser winches--but NEVER EVER for a dynamic high speed gypsy like the anchor windlass.

Imagine a ULCC being held by the windlass brake!

-- what is the principle of the windlass? -- FRICTION right?. You plan to hold a loaded ULCC in an anchorage with swell , with the ship yawing wildly, using friction?

The bow stopper must always be put. First ensure there is NO half twist between the gypsy and the stopper, as is usual.


This rendering thing is the biggest bullshit going on at sea.

On bulk carriers with crane and grabs , which tend to get buried under cargo slides, we test the cranes to proof load . On old ships the brake lining surface and the abutting surface crevice is flushed with carbon remover to get rid of the slippery heat generated graphite layer. Then we tone up the relief valve before the class surveyor comes. The tank is filled with sea water to the required weight . After lifting the proof weight the runner joystick has to be suddenly put to neutral and the crane hook must not creep downwards due to gravity --the automatic brake must grip.  After the test is over we usually tone down the relief valve to the safe working load again. So if the grab gets buried due to a landslide , the relief valve will lift.

Rendering of mooring winches can be done easily ( for the first layer ) with automatic brakes. On manual brakes the torque meter is used on the handle. All this is OK for a split drum which affords only one single layer.

But what about a usual mooring winch drum, where a hawser of 220 metres is wound . It will have minimum 8 layers. When you send the first line ashore or cast off the last line, it will usually be a spring, with 30 metres out on the jetty bollard and the remaining 190 metres in 7 layers on the reel.


Where is the intelligence is doing a brake rendering test on the first layer, for manual brakes once in a year? How relevant is the rendering set point after 365 days?.


It requires a real IDIOT to think, that the brake lining thickness will not reduce, due to wear. Will the the friction coefficient between the metal abutting surface and the brake lining be the same in dry and wet weather?

(These are the same pathetic jokers who wanted NIL vaccum with 100% recirc, or NIL fresh air intake,  for accomodation AC at oil terminals, with the toilet and galley exhaust fans running merrily.)

The forward brake abutting bands on the rotating gypsy is the most under maintained area on the ship. This area can never be painted. On better ships this brake abutting area has a stainless steel veneer. If any salt water ( electrolyte ) enters this crevice it forms a galvanic cell between the brass countersunk bolt heads of the brake lining and the steel gypsy. This galvanically weakens the steel. The surface may look pristine , but it is molecularly weakened. If you chip with a sharp hammer, chunks will break off, like a clay pot. Rendering brings out iron powder .

If the brake renders heat is produced. The heat produces slippery graphite , and it continues slipping.

And nowadays on almost all old ships we find different grades of rope being sent on board --all having the same material on the certificate. But the breaking load will be different. And 60% of this value is what the brake is rendering set point.

Ok you have 4 ropes on the winch reel and the remaining 3 are on the mooring bitt, as a figure of eight . How are we gonna render these ropes on the bitt?. So you give step motherly treatment to 40% ropes--where is the intelligence?

The modern light hawsers do NOT have a friction coefficient ( like the old polypropylene hawsers ) and they slip with a jerk, despite taking two round turns on each bitt and then putting a figure of eight and then again taking full rounds. When hawsers slip with a jerk, they always break. Very rarely can a constant pull break ropes. Anchor chains also break easily when it jerks.

Ever noticed how three tiny Yokohama fenders protect the ship side hulls of two loaded supertankers alongside each other . It is because there is NO sharp bang or surge or jerk or hammer. Remove these fenders and the steel hulls will crumple like paper.

I have taken several deliveries, where the Yard does the first rendering tests. You should see the sheepish look on the face of the man in charge. He knows he has to pull the wool over his own eyes as well as others. Well the ship need this certificate-- without this we will be detained by any inspector.

After you tighten the windlass brake band after anchoring , check how many spare threads are available on the brake handle .

The brass countersunk bolt heads must never come in contact with the gypsy steel. Metal to metal has less friction. And even if it makes contact the brass bolt head will wear off--while a steel bolt can cause havoc. There can be no steel to steel friction , and the steel bolt head will groove the galvanically weakened gypsy abutting surface.

We all play along , and tell the naked emperor--such nice clothes you wear, mE lord!. Nobody has the will to call the bluff.  We deserve to be ruled by fools ashore.

This is why millions our rat guards fell off for the past 300 years and millions will fall off for the next 300 years.

This is why we use the loud hailer cone on the bridge is applied on the mouth for shouting stupid orders. It is actually meant for putting it on your ear and finding out to min 5 deg accuracy, the direction of the foghorn you hear at sea on the bridge wings. In Titanic if the stupid British officers had applied the load hailer to their ears , to find the direction of  lifejacket whistles , instead of their big mouths shouting " Any body there ?" they could have saved more passengers from the freezing water.

Advise:  If you have drums with 8 layers of hawser turns, it is better to make sure you last lines to cast off forward and aft is a rope from the mooring bitts ( especially if the current and the wind can put the ship in trouble ). They never get stuck.

    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.

  6. THE INDIAN GOVT AND ARMED FORCES MUST DO BRAINSTORMING .

    ATTACK ONLY WEAK POINTS OF PAKISTAN . .

    THIS IS CHANAKYA NEETI . .

    one of the reasons why capt ajit vadakayil is a living legend at sea, is because i offered myself as a SACRIFICIAL GOAT just to get my kicks and play games with my detractors

    i would offer to change cargo grades which had never been tried before at sea.

    for example-- i would offer to change grade from viscous lub oils to potable ethanol or methanol fibre grade in brazil/ argentina and that too without going out to sea for open tankcleaning after unloading luboil .

    yank charteres wanted to send yank , danish and norwegian obeservers ( super cargoes ) and i would say NO PERMISSION --

    TARZAN SWINGS ALONE ON THE VINES -- AND HE WONT ALLOW IDIOTS TO WATCH FROM BELOW AND ABOVE TO MICROMANAGE HIM. .

    i make too many enemies ho are miffed with my cockiness-- if i fail i am disgraced forever and will be sacked. even the company may shut down due to losses . .

    my detractors would wait with bated breath for me to fall PHUTTTTT on mE face.

    but i would always win . .

    THUMB RULE : KNOW THE WEAK POINTS AND STRONG POINTS OF THE PREVIOUS CARGO. ATTACK WEAK POINTS . IT REQUIRED IN DEPTH TECHNICAL KNOWLEDGE FROM IONS TO ATOMS TO MOLECULES TO BOILING POINTS TO MELTING POINTS TO WHATEVER.

    THERE WAS A CASE --MY LAST VOYAGE BEFORE I RETIRED --MY TANKS ALL FAILED AT OMAN --

    ALL MY DETRACTORS CELEBRATED AND GOT DRUNK

    I CAME OUT THE WINNER AGAIN--SO WHAT ELSE IS NEW ?

    I CHALLENGED THE COMPETENCE OF THE GORA INSPECTION LAB ..

    I DID TESTS ON MY OWN SHIP --IN THE PRESENCE OF LAWYERS FROM LONDON-- HAD THE TESTS VIDEO TAPED .

    THE VERDICT?

    THE SHORE LAB , MUST RE-TRAIN THEIR TECHNICIANS -- THEIR PROCEDURES WERE NOT SCIENTIFIC -- THE TOP BOSSES GOT SACKED.

    THIS IS THE REAL MEANING OF " GAAND MEIN TATTI " OR BALLS WHICH CLANG AND EMIT SPARKS .

    TODAY EVEN MY DETRACTORS WHO GOT DRUNK-CRY-- THIS WILL NEVER EVER HAPPEN ON THIS PLANET . .

    i want all my readers to read above TWO posts--

    LIFE LESSON IS INHERENT !

    ONLY YOU CAN FAIL YOURSELF --NOT ANY OTHER MORTAL ON THE PLANET- THE DAY YOU CAN DO THAT, YOU ARE LIBERATED.

    VADAKAYIL KHUD EXAM PAPER DAALTHA HAI

    VADAKAYIL KHUD IMTIHANN LIKTHA HAI

    VADAKAYIL KHUD NUMBER DETHA HAI . . .

    WHATEVER YOU DO IN LIFE--UNDERSTAND WHAT YOU DO-- 100% FROM MACRO TO MICRO LEVEL-- GO FROM TELESCOPE TO MICROSCOPE MODE AGAIN AND AGAIN
