The HOLD Offshore Conversion Kit can be installed on either the HOLD 2500 RCD or the HOLD 1500 RCD bearing section as needed. The Offshore Conversion kit modifies the top of the HOLD RCD to provide a custom flange at the top of the RCD. A typical installation would provide a top flange with a welded-on 24 inch OD Overshot Mandrel to engage the Overshot Packer for jack-up or tension-leg drilling platform installation, however, almost any configuration of equipment can be provided.

The HOLD Offshore Conversion Kit can be installed on either the HOLD 2500 RCD or the HOLD 1500 RCD bearing section as needed. The Offshore Conversion kit modifies the top of the HOLD RCD to provide a custom flange at the top of the RCD. A typical installation would provide a top flange with a welded-on 24 inch OD Overshot Mandrel to engage the Overshot Packer for jack-up or tension-leg drilling platform installation, however, almost any configuration of equipment can be provided. While the Offshore Conversion Kit is not designed to be a structural member of the Marine Riser, it provides a fluid connection to enable flow through the RCD to the diverter and bell nipple used in many typical marine installations, and substantial side loads can be accommodated which help maintain RCD alignment with the rotary or top drive above. A 16.8 inch minimum ID is required above the RCD to allow installation of the stripper rubber elements. The maximum OD of the bearing assembly with the conversion kit installed is 30 inches, and it adds approximately 3 inches to the height of the RCD. HOLD Offshore Conversion Kit Components
