Slip bowl load transfer system
Abstract:
A slip bowl load transfer system includes a first slip bowl assembly and a second slip bowl assembly. The first slip bowl assembly, adapted to engage and release a tubular member, includes a first slip bowl coupled to a second slip bowl. In an engaged state, the first slip bowl assembly imparts a compressive force on a portion of the tubular member between the first slip bowl and the second slip bowl. The second slip bowl assembly is adapted to engage and release the tubular member and is aligned with the first slip bowl assembly. When the second slip bowl assembly is engaging the tubular member in a second engaged state, the second slip bowl assembly is prevented from releasing the tubular member if the first slip bowl assembly is not in the engaged state.
