What are the recovery methods if the riser pump fails?
If the EC-Drill® subsea pump fails, operations can continue conventionally. Pump recovery depends on installation method—either pulling the riser or retrieving the pump separately.
If the subsea pump fails then operations can always be continued conventionally, with a full riser and mud returns to surface.
If the subsea pump module is attached on the riser and EC-Drill is required for the section, then the riser will need to be pulled to the pump location to recover the pump.
If the subsea pump module is run separately on drill pipe or on cable, then it can be recovered without pulling the riser. The pump can be replaced offline when run with cable or dual derrick rigs when run on a separate pipe.
