CAN is redefining the standard in structural wellhead foundations.
This technically superior solutions has been proven in 22 installations, to cut well construction time and cost, reduce risk and improve safety.
What is a CAN?
The CAN (Conductor Anchor Node) is a combination of suction anchor and one joint of conductor. The suction anchor pushes the conductor into the seabed, providing top support for the well.
This solution was developed to facilitate installation of the top hole with light vessels, providing operational and commercial benefits by enabling the subsea well foundation to be in place before the rig arrives on location.
Once installed, the CAN provides a smarter well foundation, removing the risks associated the conventional wellhead system which is widely recognized as the "weak link" in well design.
Conventional wellhead - the "weak link"
CAN - the smarter well foundation
Cementing quality and top of cement
Risk of requiring top-up cementing
Conductor installation rig time
1 - 3 days
Calculated and verified
Ensured - pre-installed in the workshop ensures quality and integrity
Example of the challenges of a conventional wellhead
CAN installed on the seabed
Why use a CAN?
This novel and patented approach of developing and installing a subsea wellhead foundation delivers a range of commercial savings and operational benefits when running exploration and production wells.
Zero rig time: pre-installed by a vessel
Managed fatigue capacity
Load capacity is calculated and verified
Pre-installed conductor in the workshop, ensures quality and integrity
No cementing or grouting
Reduces risk due to reduced open-water rig operations making risk management ALARP
- Hand's off conductor installation
- Reduced heavy lifts
- Simplified logistics
- Best available practise
Reduced season dependancy
Reduced project execution time
Saves 2 - 4 rig days
Pre-mounted equipment cost savings
Accellerated production can impact the Net Present Value of the well
