ArticuLock drillpipe technology increases operating envelope and reduces waiting on weather time

The OGTC funded a project with Deepwater Oil Tools to develop, test and certify ArticuLock - a special articulated joint within the drillpip running string. This is used when deploying subsea equipment through the drilling rig during well construction. The technology enables drilling operations in rough weather conditions, reducing waiting on weather time, which is a multi-million pound issue annually to the drilling industry.

Industry Value

Approximately 25% of subsea wells could benefit from this technology, increasing the operating weather window by up to 35% - resulting in multi-million pound savings.

Key Results

Deltatek's ArticuLock® technology provides open-water, riser, casing or landing string articulation, even in extreme storm conditions to:
- Expand the weather window for deployment of sub-sea trees, flow-bases, EDP/LRPs, casing strings etc by >400%
- Eliminate low cycle fatigue (remove stiffness) associated with hang-off or suspending loads during riserless or open-water operations
- Provide a contingency to allow subsea deployment or intervention operations to continue even in high significant wave height, sea-swell or loop current conditions
- Reduce waiting on weather time

The project has field trialed the ArticuLock tool concept in an operational environment, proving the ability of the tool to interface with racking equipment and rig floor hardware, as well as executing long term degradation testing of the ArticuLock, by use of substantial hanging mass (65MT) to represent actual subsea hardware being installed beneath the tool, and allowing the ArticuLock to demonstrate its functional performance in the intended load condition

Lessons Learned

Following the long term degradation testing of the ArticuLock tool it has been learnt that over 70 days of constant use tool life exists before seal integrity begins to degrade

Next Steps

To use ArticuLock in a commercial environment to aid Tree Cap Running Tooling engagement on old wells with inclination at the wellhead not suitable for rigid landing string techniques, alongside deployments to improve fatigue life of traditional wellhead running tooling.
