Claim:
An offshore wellbore assembly comprising: an offshore platform; a tension lift frame for connection to a wellhead, wherein the tension lift frame is a free standing assembly that is supported by the platform, and wherein the tension lift frame comprises: a compensation system which compensates for heave motions from the platform; vertically extending columns which support a coiled tubing injector and a blow out preventer, wherein the compensation system is connected between one of the vertically extending columns and a blow out preventer carrier, which is movable on the vertically extending columns and supports the blow out preventer, and wherein each column comprises an upper column portion pivotally connected to a lower column portion, allowing the tension lift frame to be compacted for ease of maneuverability during installation of the tension lift frame on the platform; and a base which supports the vertically extending columns, wherein a horizontal cross section of the base defines an area which is larger than an area defined by a horizontal cross section of the vertically extending columns.
