Halliburton has announced the release of the Dash® Large Bore Subsea Safety System, which provides full electrohydraulic control of well safety and intervention functions. The fully customisable system brings new benefits to deepwater operators for completion and intervention work that improve critical well control of the subsea safety system, tubing hanger and deepwater subsea field developments.
Halliburton collaborated with customers to design a system that is simpler to test, easier to assemble, faster to activate and configurable to individual customer and project requirements. It can isolate the lower landing string in as little as six seconds or less, disconnect from the lower landing string in as little as ten seconds or less and provide downhole data for greater confidence in decision-making.
The two larger bore sizes, 6 3/8 inch and 7 3/8 inch, in addition to the existing Dash 3 in. system, broadens the use of Halliburton electrohydraulic subsea safety systems. Operators will now have the ability to deploy this technology across the full breath of their ultra-deepwater offshore operations to help minimise operational risk.
"The Dash large bore system adds to our capabilities by providing a technology that we believe is more effective and efficient," said Grant Roscoe, vice president of Testing and Subsea. "This launch furthers our commitment to helping customers reduce their deepwater development costs without compromising safety."
Noble Energy used the Dash large bore system during recent plug and abandonment operations in the Gulf of Mexico. Dash safely and effectively served as the primary well control barrier and blowout preventer. This dual functionality eliminated the need for alternative measures during the operation, which reduced rig time by several days.
