This is a very crude animation, the big picture is that it will work, and without oil output PSI, bottom contour, etc, but this will stop flow, and that has to be primary.  

This solution was rendered since I had finally seen actual oil components, and problem, this idea will also work w/out riser!, it can plug ANY pipe circumference, given correct specs for build of component, other ideas on this site were for seafloor hole w/out head unit.

Or dropping entire net filled with sandbags as to keep primary sandbags from falling in hole, then compiling can occur, and continuous dropping will seal oil hole.

another type of oil plug so to speak, would be a weighted heavy duty balloon, in which balloon can be guided into hole, as attached with either pneumatic line hoses, or water hoses that would pump either component from surface ship, water of course would be ideal as not to float out before expansion of balloon seals oil hole. 

as above the umbrella type valve would go into hole, as an upside down umbrella, then open and oil pressure against it would create massive pressure against outside ring of umbrella which would have barbs that would dig into circumfrence of hole, while this is taking place a component such as sealing cement can be administered

Also, either an upside down umbrella type valve to grasp sides of floor, or a balloon type valve with pressured water to fill and close gaping hole in floor would also work....has to be done now.....Larry Wallace, designer.
