The Dual Isolation Valve is configured directly above a deployment bar and beneath a deployment connector in a lower BHA section. Using the BOP pipe rams to secure and seal across the deployment bar, in the “Closed” position, the LiMAR® Dual Isolation Valve provides a double barrier whilst connecting the upper section of the BHA. Once the BHA has been assembled and integrity tested, the Dual Isolation Valve can be locked into the “Open” position ready for the riser to be stabbed on, ready for operations to commence.
