Subseadesign’s new CPRT delivers proven reliability

Great news from operations in the Caspian offshore basin last week and earlier this January.
One of the major subsea operators successfully deployed the second-generation Crown Plug Running Tool (CPRT), developed by SubseaDesign, and both recovered and later installed a crown plug without any issues.
The tool performed exactly as intended, and no onshore support was required during the operation.

Based on operational feedback, the total time from overboarding the CPRT to safely recovering it back on deck was approximately ±4 hours (excluding transit time). The operational team onboard the vessel now has great confidence in this tool and how it performs.

The crown plug is engineered for open water operations, enabling efficient installation and retrieval of the Upper Crown Plug on horizontal X-mas trees, eliminating the need to run the crown plug through the BOP. The Upper Crown Plug operation has sometimes proven to be inefficient, time-consuming, and therefore very costly. This new generation of wireline operational LWI tool is expected to reduce time and costs effectively.

The overall feedback highlights the strong performance and reliability demonstrated offshore. This is a testament to the solid engineering behind the solution — well done to the SubseaDesign team for delivering a robust and reliable tool.
