preparing a tank calibration of a tug, need scantling of vessel

Hi Gonzo,
All depends on that for what account there is a speech: account of the construction of updated tanks plating and frame on local strength and plating stability in correspondence with Rules or account of volume of the frame as a share of maximum theoretical volume of tanks. I have understood from the information of our friend from Dubai that he already has made first, i.e. has already choose all structural members and is interested only from second. My explanation is for it and Tansl well fathoms it and when links my text from that he to speak about deformation it already is a sneer. It is not so collective tone.
And basically you have correctly asked about tests of tanks. Certainly chosen new construction should be tested and on deformation at a test pressure according to Rules.

 

I will try to explain my self, trying not to disturb anyone.

1. I have always understood that we were talking about the calibration of the tanks.
2. In no time I have spoken about structural stabilities of tanks plating.
3. The explanation of the procedure developed by Rabah was so thorough that I missed an element that usually has more influence than the amount of welding : deformation of the tank walls. All tanks, when subjected to the leak test, undergo deformation. So take this into account when you want to perform a high precision calculation as described by Rabah, is not trying to tease anyone. From my point of view, given the degree of presicion used, is a very pertinent question.
4. I respect any professional in naval sector, even if they don`t design warships.
5. Try overwhelm anyone who makes a request speaking of things that what they want is, rather than help, demonstrating the immense wisdom of who makes the answer, I feel pathetic.
6. I know much better what a large steel ship is than a GRP boat.
7. Tugs, with which I have worked very hard, for me are small boats.
8. The calibration of tanks, for me, is a heavy, tedious work, but without any difficulty. As a technician, not a job to wake me wonder. Just feel sorry for the person who has to, because it is a very boring job. Do not think it's a job to be published in a technical journal.`
9. I can not judge anyone for the photos he puts in his gallery but by what he said in this forum. If he says something that, in my opinion, does not help or does not come to mind, I'll say it clearly.

Cheers

 

Dear Tansl,
Also you started to use cunning to be getting out of the absurd situation. Each shipbuilder - professional would understand it. As has explained to Mr Gonzo, calculation of the plating and the frame on strength and plate stability it is a stage which will precede a subject of our dispute.
There is the Algorithm:
1. You complete all repair work
2. You make watertightness tests of all tanks on the instruction approved from Classification organization
3. Launching
4. Heeling test
5. Correction of Stability booklet with the received data from Heeling test. Right now it is necessary to repeat the calibration of tanks with accounts of the frame to have valid gauge tables. And it any more has no anything general with tests!

But I am glad that all the same we have reached definite progress, as soon as you have already declared that be respectful / instead of with contempt / for all colleague shipbuilders.
In effect I should you thank for all that you have written about me because it has increased the rating of my publications and more people of them will read.
I think that this forum not arena for gladiatorial battles, and the place where is possibilities to exchange ideas from people the too trade.
Really it was not more correct to act as gentleman and to apologize about unjustified attacks both unfounded quarrelsome and derisive remarks?

 

Make it clear that I have not written anything about you but I have expressed my opinoión on similar work that you have done: they have nothing to be proud of.
That said, it has been a pleasure. I like to think that I help the participants in this forum, but frankly have 25 visits to your files in 26 days is not a record. Despite my invaluable help. You're welcome.
