DTI unveils streamlined riser recoil valve

HOUSTON – DTI has introduced a new riser recoil valve that offers an efficient, reactive, and reliable option during planned or emergency riser recoil events. The streamlined, patent-pending design behind this new technology improves riser recoil valve performance.

Since the system has fewer moving parts, it eliminates risks for malfunctions and leads to greater reliability and easier maintenance.

The role of the riser recoil valve is to regulate 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 company says the streamlined design of the valve improves flow efficiency, directly and positively impacting the system’s response time. Function tests performed 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 reduced.

David Trent, president and CEO of DTI, said: “The DTI riser recoil valve is the most current and advanced design available. It provides the most efficient control solution, which is reliable, reactive and easier to maintain. As the industry standardizes with this riser recoil solution, we will see a positive change in the planned and emergency disconnect operations and safety.”

The DTI riser recoil valve operates in all modes of operation, and it can be installed to improve performance on existing drillships as well as newbuilds.
