The Dash® electrohydraulic control module system

New generation electrohydraulic control system

The Dash electrohydraulic control (EH) control system brings speed, strength, and simplicity to well control. This key technology is designed to work in conjunction with Halliburton’s Veto® subsea safety systems. The Dash EH system should be added to the Veto system when a rapid well shut-in and unlatching of the landing string may be required. This is of paramount importance when conducting well testing activities from dynamically positioned drilling vessels in water depths up to 10,000 feet (3,038 m).
