Specialist Offshore Double Block and Bleed

Availability: Rental, Sale

The Specialist Offshore Services’ double block and bleed panel is meant for use in pressure testing subsea assets.

Specialist Offshore Double Block and Bleed

Specialist Offshore Services provides a double block valve arrangement with a 3rd valve added. As a result, this allows the user to vent the pressure from between the valves. Thus giving the user the ability to use accepted subsea procedures in pressure testing. The panel designed by Specialist Offshore Services turns out to be a major time saver as there are no manip operations required. This is due to 1/4 turn rotary actuators controlling the 1/4 turn valves when connected to the ROV hydraulics. Each valve requires the use of an ROV Solenoid to open and close it. The units are customisable for different working pressures without changing the 1/4 turn actuator.

The unit can be mounted on a underslung or rear mounted skid or any other custom location. Pictured is the unit designed with secondary ability to use a manip if required as a secondary means of operation. Therefore the unit must be mounted within reach of the 7F Manipulator. The pictured is for attachment to the Schilling 5F Manipulators, but the unit could be placed in the skid drawer.
