DTI introduces a new riser recoil valve for planned or emergency riser recoil events. The streamlined, patent-pending design behind this new technology significantly improves the riser recoil valve’s performance. The system has fewer moving parts than competitive valves, which eliminates risks for malfunctions and leads to greater reliability and easier maintenance.
The riser recoil valve regulates the fluid between the accumulator and cylinder to control rod extension, making it a vital safety component. During normal operations, the valve remains completely open. When a riser recoil or wireline/riser parting event is introduced, the valve closes accordingly to limit the flow of fluid and control extension of the cylinder rod, reducing the possibility of damage to the vessel, risers and wellhead systems.
The streamlined design of the DTI valve improves flow efficiency, improving the system’s response time. Function tests on the DTI riser recoil valve produced a near-instant response time from fully open to fully closed, which improves overall safety as the risk of damage caused by a riser recoil event or wireline/riser parting is significantly reduced.
The DTI riser recoil valve operates in all modes of operation, and it can be installed to improve performance on existing drill ships as well as new builds.
