Abstract
A deployment tool that can be used on land, jack-up and floating drilling rigs. The tools is installed around a drillpipe tool joint making it independent of the drill string load path as well as independent of the drill pipe thread and drill pipe size. It is designed for the largest commonly used drillpipe size, so has a single outer dimeter configuration that can be adapted from the largest drillpipe to the smallest in use with simple mechanical adapters. Thus, one main tool and a set of adapters is all that is required. The tool may be used in the deployment of RCDs, for example in the landing of an RCD bearing assembly on an RCD housing, or in the deployment of tubing hangers, lining hangers, casing hangers or other or any other temporary completion tool.
