ABSTRACT:
An auxiliary offshore rig adapted to be used for relieving the primary offshore rig on an offshore platform of well activities relating to tubular member or cable operations. The auxiliary offshore rig includes in one embodiment a truss member mounted for movement along the platform, a racking tower for receiving tubular members therein mounted on the truss member, and a working cage mounted within the racking tower and supported by the truss member adapted to be positioned in alignment with the well for providing a secondary working area beneath the rig floor which is mounted atop the racking tower. In a second embodiment, the auxiliary offshore rig includes the truss member, the racking tower, and a drill tower which is mounted atop the racking tower for use in drilling operations, the drill tower supporting a crown block assembly movably mounted upon a crown block support member mounted with the upper end of the drill tower, with the crown block assembly supporting a travelling block for vertically moving tubular members with respect to the racking tower.
