Abstract

A deployment collar 10 for temporary mounting to a substantially cylindrical centralizer (1 fig 3) for centralising a tubular member (5, fig 1) within a bore 7, the deployment collar includes a ring-like main body 27 defining a longitudinal axis 104 of the deployment collar. Mounted to the collar main body 27 is a latching mechanism 15 70, 73, 77, 79, 90 and an activating mechanism 40, 61, 63. The latching mechanism is provided around the collar main body 27 for latching to and de-latching from an upper end of a centralizer so that, in use, the deployment collar may be temporarily mounted to said centralizer. The activating mechanism includes at least one actuator 40 that is configured, in use, to applying a force in an axial direction for activating a radial adjustment mechanism of said centralizer.
