Do I need to change EC-Drill® between sections?
The EC-Drill® equipment remains subsea with the drilling riser throughout the entire well operation and does not need to be changed between sections.
No, the EC-Drill® equipment is run with the drilling riser or on a separate hang-off line. It remains subsea and available for use during the entire period of the well drilling operation. It is then recovered with the BOP at the conclusion of the well or by retrieving the hang-off line.
