UUV Thrusters Selection and cable drag

propulsion
drag

#1
  1. I want to select the thrusters for a small uuv having drag from 0.7 - 0.9 kN at depth of 100 m with cable length and diameter 1000 m and 3 mm receptively. How should I calculate the cable drag? should i calculate the drag of UUV with thrusters or without thrusters?

  2. Kindly recommend the thrusters for the given drag of UUV?

Positive response will be highly appreciated.
