Trim Calculations - Part 3 (Advanced Ship Stability for Mariners)

This video is Part 3 in the series of videos on solving questions involving trim calculations of ships.
The calculations form part of the advanced ship stability for mariners, particularly chief mates and master candidates intending to appear for certification examinations.
Link to Part 1 is provided below.

Well done, thanks!

[@arun2857]

Thanks alot sir, i have cleared my doubts in trim, God bless you

[@SteeringMariners]

You are most welcome, glad it helped:)

[@raymondallenjhangiani7670]

Thanks 🙏 sir ! Very well explained although I do have to watch it repeatedly in order to get it registered clearly into my mind ? Nevertheless , your method of delivering the subject is truly commendable and deserves many thanks n applause from all your channel viewers 🙏

[@MsDhiraj123]

Sir pls guide for radar

[@phumezajili7382]

Please kindly explain Trim type B

[@AjayYadav-bv7ex]

Can u plz explain exercise 22 captain subramanian trim type A problem 16-20 sum

[@Moonlight-zt1qn]

Its informative but the volume is very low I can't hear if I dont use headset.

[@aldrinantony5402]

Sir, in the 2nd question I assumed HF was behind H, but my final answer came -2 mtr. So should I take it +ve and conclude that my HF is fwd. Is that possible sir. Please advice

[@Radhika-r5p9f]

Sir voice is very slow but very well explained

[@imanpoloei9443]

sir excellent thanks alot for your good description but i have questions in EX.1 why for cargo to be loaded you after (9.6-9.1 ) *35 also multiply 100 i do not understand this logic of multiply 100 ?

[@SteeringMariners]

Good question, I converted the difference in draft from metres to cms. This is required as the TPC is for the unit of cms. Hope you got it?

[@imanpoloei9443]

@@SteeringMariners I got it All the best
could you pls solve the EX.22 , Q8 of Subramanium . God blessed you

[@denniskavukattu2338]

Sir , first question after finding the cargo question asking calculate final drafts fwd and aft this is not mentioned in video

[@lihaylihayjoserielm.7752]

i dont get why did it come to 2 mtrs fwd of amidshi8ps caan someone explain to me?

[@sapangambhir4537]

Hello sir can you please put one problem of hindship about change in trim with change in density

[@SteeringMariners]

I will put it up today:)

[@mythicalstories2402]

Sir, please provide stability questions related to drydocking and grounding

[@SteeringMariners]

I have put up questions on drydocking. You can find it on the 'ship stability' playlist.

[@eanean3831]

Sir i'm confusing how do you calculate the 2 meters result from forward of mid ship?
IF;
77,000 - 48,000 = 29,000
200 * 175 =35,000
35,000 - 29,000 = 6,000
How do you calculate the 3,000 and the result of 2 meters forward of the mid ship?

[@vkmariner2371]

Sir when density change and we need to find fwa then which displacement u should take..final displacement or intial.please advice

[@SteeringMariners]

when the density changes, the under-water volume changes. The displacement remains the same. When the under-water volume changes, the draft changes (since the length and breadth of the vessel can't change). The difference in drafts is what gives you the allowance.

[@vkmariner2371]

@@SteeringMariners thanks for reply sir but when initial displacement is given and after that we load some other cargo that time which displacement we should consider for to find fwa and mctc.
