摘要： Techniques for coordinating performance of operations in a well system including receiving, using a central controller, a request to perform a next operation associated with a first operator that includes changing well system equipment from a current equipment state to a target equipment state from a first operator device, determining, using the central controller, whether completion confirmation of a preceding operation associated with a second operator has been received from a second operator device, in response to determining that the completion confirmation of the preceding operation associated with the second operator has not been received, blocking, using the central controller, the first operator from performing the next operation from the first operator device, and in response to determining that the completion confirmation of the preceding operation associated with the second operation has been received, permitting, using the central controller, performance of the next operation associated with the first operator.

摘要： An adapter for coupling wellhead pressure control equipment to wellhead mounted equipment, includes a breech pin and a breech lock base assembly. The breech pin includes a tubular breech pin body and a rotating breech ring. The rotating breech ring is coupled to and rotatable relative to the breech pin body. The rotating breech ring includes a breech ring body and one or more breech pin teeth extending radially outward from the breech ring body. The breech lock base assembly includes a tubular base assembly body. An upper end of the bore of the base assembly body defines an upper receiver. The breech lock base assembly includes a fixed retaining ring including one or more fixed breech teeth. The fixed breech teeth extend radially inward into the upper receiver. The fixed breech teeth are positioned to correspond with the spaces between the breech pin teeth.
