is it possible to use NDT UT to test under sea fiber

hi
is it possible to use NDT UT to test under sea fiber(the shield only)?

If you can first set up an immersion tank and put a small length of the cable in it and validate the UT immersion set up successfully, translating it for undersea cable testing may not be too much of a problem. So, I would suggest that you first complete the lab part of the set up.

thank you. I'm working on my university thesis. and before doing any thing I want to know if it is possible and my effort is not impracticable. I only want to design and test it in lab range.
does the NDT UT work on suffaces like under sea fiber optic cables cover. it slim (~2 mm) and other layers are under it. and some of them are not glossy. and other problem is the layers that are made under sea like sediment that is not possible to clean all the length of the cable to test. is it a method to test it under this situations.

In that case, a thorough search should bring up the feasibility studies if any already conducted. You should in any case, do an experimental set up to validate the theory. In theory it is possible to transmit sound through several layers of different materials and detect imperfections in each of them. Practice is quite different from theory however and the testability depends on many factors. I am writing out of my general knowledge and confess that I have not done any studies myself.

Best wishes.

Undersea cables are designed for a wide range of applications. (Pressure, flexibility, abrasion resistance etc) Usually the different layers perform different functions and are made of quite different materials. Its fairly unlikely that you will get much sound past the first layer. But each case is different. Its worth a try.

is there any effort doing this. I need it to use the results of experiences. I could not find any.
thank you Sirs.
