Ship Stability - Center of Buoyancy (KB Calculation)

Using examples, this video shows the procedure of calculating the KB (distance between the keel of the ship and the centre of buoyancy (COB) and the draft of the ship. The position of the COB affects the overall stability of the ship. This video discusses examples of a box-shaped, triangular, and cylindrical-shaped vessel.
This is video 7 in the series of videos on ship stability. Students are advised to watch the previous videos (links below) before watching this video.

Very useful sir

[@aniketbhalerao3010]

Thank you so much Sir , it really helps a lot ❤️

[@manoranjansahoo6619]

Plz add one tricky problem also ... like chapter 8-Ex-8 -Qn9/10 from capt subhra’s book. It will be very helpful . Your explanations are really very very nyc👌🏻👌🏻. Downloaded all ur play lists also.. plz add the tricky ones

[@meeranahamed6809]

Sir they are very useful...put more vdo

[@ilgnozgul2938]

Thank you so much.

Thank you sir 🥀

Hi, do you have any video which it explain how to calculate VCB using Simpson rules when the vessel has trim by forwar or by aft? thanks for your help

[@inhindi4143]

Nice sir

Thanks sir🤩😍

Please solve this question -The deck and keel of a flat bottomed barge are identical. Its sides are vertical. The
deck consists of two sections - the bow is a triangle 15 m broad and measures 10.5 m
in the fore and aft direction, the mid body is a rectangle 60 m long and 15 m broad. It is
floating on an even keel with a displacement of 5497.64 tonnes in SW. Find the
position of its COB with reference to the keel (KB) & also with reference to the after end.

Question 9

[@hrishikeshpadaval96]

Sir how will you calculate for a Trapezium shaped vessel?

[@83Goodyear]

I'm confused as to why when calculating the immersed area of the triangle (ADE) the value for Base is 12m. Isn't that the measured distance of BC and therefore DE cannot be 12m. From a question on your previous lessons (Press Thrust Calculations on a triangle) you showed how to calculate the immersed area of a triangle (using Pythagorean Theorem), which considered Base to be at the waterline and not the deck line.

[@83Goodyear]

I should also add that these lessons you have put together have been amazing in assisting my studies. Great content. I just can't move past this question...

2nd ques me displacement nhi di h meri book me

[@thesailorfromindia1218]

Sir please make the video of exercise 8 question 8 to 10 please sir it's very important.
Please sir please
