The CAN-ductor solution is ideal for subsea development wells as it provides a robust and proven structural well foundation.
The CAN-ductor is installed from a vessel ahead of rig arrival, and installation quality is verified pre-rig arrival. This removes the conductor hole drilling, conductor running, and cementing operations from the rig schedule and saving CO2.
Load capacity is calculated onshore and verified during installation to ensure quality and integrity.
