Zusammenfassung:A lockdown sleeve 30 includes upper 34 and lower 32 portions that are rotatably coupled together such that the axial length of the lockdown sleeve can be adjusted by rotation of one portion of the lockdown sleeve relative to the other. The lockdown sleeve can maintain the lower portion stationary relative to a casing hanger while the axial length of the lockdown sleeve is adjusted. The upper and lower portions may be threaded together, and the lockdown sleeve may have a locking ring (fig. 2, 106). The lower portion may have a load shoulder (fig. 7, 600) to support a running tool.
