Deepwater Horizon Oil Leak Repair Parts

1. Cut a slot in the riser pipe with circular saw
2. Slowly insert steel plate to gradually block most of the bore, slowing crude flow rate, gradually building backpressure.
3. With flow rate throttled down, do a successful top kill

Minor modification of a grapple like one below could attach an apparatus that could insert a steel plate into the riser pipe. The grapple is needed to anchor the operation.

Grapples to grab the riser pipe

Adapt a grapple like one of these Dymax units to include plate insertion device

Thanks to Dymax Inc for posting the pic.

Additional grapples can and should be fixed to riser pipe and chained to weights on ocean floor to provide anchoring support for when pressure builds in the riser pipe so the riser and BOP don’t get pulled off the well casing pipes.

With a steady and slow decrease of diameter, the pressure will build…

With a decrease in flow rate, all the drilling mud will not get “washed” out.

  1. That looks good. A slight incline in the cut may help to hold the steel plate in place.

    I am hearing different pipe size diameters: 7″ & 19″. Resin Systems of Calgary makes strong composite poles which gradually decrease with height. One could be inverted and stuffed down the well while letting part of the oil flow up its center. Unfortunately the narrowest possible end is 8.25″” and won’t even enter the 7″ pipe but would create a gradual block as it were lowered 42′ down the 19″” pipe.

    I checked out a lot of the BP youtube channel late last night and caught a lot of info on a couple of cable channels.

    I didn’t know about the pipe-within-the-riser pipe… I guess it really wouldn’t matter to the steel plate choke-type thing I’ve advocated for.

    The riser pipe was cut very close to the top of the LMRP… so it’s not like there’s a whole lot of riser left to do the slot and steel plate thing.

    Whoever directed the riser cut has obviously never taken a chainsaw to a large tree. Of course the damned thing was gonna get stuck.

    They could re-cut it now and get a smooth cut…

    However, after seeing video of the diamond-steel-rope saw, it’s obvious that manufacturer has the expertise to make a clamp-on grapple.

    I’ll have to do another post on the idea that gave me…
