In one embodiment, a support structure for use on a rig floor and for supporting a unit used to manipulate tubular components through a wellhead comprises a support plate adapted to securely mount the support structure to said unit, a passage in the support plate of sufficient diameter to allow tubular components to pass therethrough, a plurality of rig engaging members and at least one tensile member mount. The unit used to manipulate tubular components through a wellhead may be a compact snubbing unit or may be a push / pull unit. The support structure may further comprise a worker platform to support a worker above the rig floor. Various push / pull system embodiments, for use on a rig to manipulate tubular components through a wellhead, are also taught. |
