even if the sub is sunk in 30feet water it seems impossible to reach in there in time.
such vessels do exist to execute tandem lifts but we dont seem to have a single one

mainly they are used in offshore oil/gas industry. so 2000t is not a issue with these puppies.
dragging is a possibility... but at shore, we definitely need some ramps that gets hooked on to some geared pulley-chain system driven by some heavy pull mechanism.
Think out of the box dear Dr. Watson
1) the sub is close to berth
2) it is reachable by the wharf / Jetty
all you need is individual
floatation devices such as rubber doughtnuts hollow in which you pump high pressure air
put a number of the m along the the x axis of the sub
hook a crane to blown front part so as to float it or allow it to surface on its tail section ie propeller side with out scratching the bronze propeller
Finally after comple inspection
dis mantle piece by where ever possible or gas cut so that
1) Salvage for spares ( as Mother Russian is so reliable for spares)
2) to completely understand design , manufacture of the sub and its sub susb ( aka in Hindi all all systems)
this is god send oppportunity to learn such that those who sacrificed their lives does not go waste.
1) metturgy
2) welding technology
3) sequence of asembly
4) Spacing of susb subsystesms
5) explosive effect on the sub
Most importantly how it can be contained, isolated if it ever (God forbid) happens deep in underwater sea.
I have some ideas but ....
