Abstract
A wellhead clamp for elastically deforming a wellhead housing to grip a wellhead hanger is provided. In one embodiment, a wellhead clamp () includes a first energizing ring (), a second energizing ring (), compression segments () positioned between the two energizing rings, and segment retainers () fastened to the compression segments and to the energizing rings. The segment retainers retain the compression segments between the energizing rings and hold the energizing rings apart in an expanded arrangement that allows the compression segments to be in a radially retracted position that facilitates running of the wellhead clamp onto the wellhead housing (). A setting tool () can be used to apply a setting load to the wellhead clamp. The setting tool can be a hydraulic setting tool with pistons (), which may be bidirectional pistons in some instances, to apply the setting load. Additional systems, devices, and methods are also disclosed.
