Deep water continues to demand cost effective, efficient solutions from manufacturing through operation. Existing designs of electrohydraulic (EH) control systems are large and complex, making them slow to produce, difficult to maneuver offshore, and inefficient to redress and maintain.
The Dash® Large Bore Subsea Safety System is an all-new EH system for large-bore subsea well-intervention applications. The system is simple to test and simple to assemble. It isolates the lower landing string in less than six seconds, disconnects from the lower landing string in less than 10 seconds, and provides seabed and upper landing string data for greater confidence during operations. Developed to meet the latest ISO and API standards, the Dash system was built on proven products, and is customizable to meet individual customer requirements.
Halliburton has collaborated with its customers to determine what is truly needed for EH systems. The Dash Large Bore Subsea Safety System reduces the required time to safely close and unlatch the subsea safety system during emergency conditions, and also provides greater integration flexibility. With the industry focused on efficiency, broad integration capabilities are critical for lowering cost. The Dash system delivers a customizable data-monitoring solution for both the subsea safety system and pass-through controls.
The Dash Large Bore system has been designed to ease assembly, simplify maintenance processes, communicate real-time landing string conditions, simplify re-latch operations, and provide faster activation response times. Ultimately, it produces a more reliable EH system.
With the Dash Large Bore system, we can lower the cost of deepwater development without compromising safety.
The electrohydraulic Dash® large bore subsea safety system was specifically tailored for the operation and was deployed for the two-well campaign, providing more real-time data to the operator and giving it the ability to isolate and disconnect from the well faster than traditional systems without compromising safety,
