Can the "venturi effect" cause a nuclear sub to "rise" from underneath a 300,00 ton tanker" passing over?

Question

You have a 6900ton submarine submerged traveling at slow speeds and a 300,000 ton tanker traveling at flank speed directly above on the surface. Can the tanker's movement cause the sub to "rise" to the surface and "strike" the tanker?

Answer 1

There will be a lower pressure due to the velocity of the water from the drag of the tanker. That lower pressure area when entered by the submarine will create a slight lift, however that slight lift is minimal if even noticed and would be corrected by the helm long before a risk arrives.

Answer 2

It is unlikely given that flank speed for an oil tanker is probably no more than 14 or 15 knots. The velocity of the water moving past the tanker is in the laminar flow region, so the change in momentum at the back end of the tanker is trivial.

When a submarine hits a surface ship, it is always due to error by the officer of the deck onboard the submarine. Unfortunately though the captain of the ship will be held responsible as well.

Answer 3

though the probability is low, it is possible. so many factors to consider on this question it is mind-boggleing.
more and specific data is needed, engineering drawings, weather data, ocean conditions at various depth levels, etc.
