Abstract
In one aspect the invention provides a support structure for use on a rig floor and for supporting a unit used to manipulate tubular components through a wellhead, the support structure comprises a first section, a second section and a central passage of sufficient diameter to allow passage of the tubular components therethrough. When the first section and the second section are assembled together, said sections together are suitable to support said unit used to manipulate tubular components through a wellhead.
Claims15
A support structure for use on a rig floor and for supporting a unit used to manipulate tubular components through a wellhead, comprising:
- a first section;
- a second section;
- a first leg and a second leg projecting from the first section;
- a third leg projecting from the second section;
- and
- a central passage of sufficient diameter to allow passage of the tubular components therethrough;
- wherein, when the first section and the second section are assembled together, said sections together are suitable to support said unit used to manipulate tubular components through a wellhead;
- wherein, when the first section and the second section are assembled together, said first leg, second leg and third leg support said unit used to manipulate tubular components through a well head in an upright manner on the rig floor;
- wherein the first section of the support structure further comprises a first central passage recess which has an opening of sufficient dimensions to allow a tubular component to, at least, be partially placed into the first central passage recess;
- wherein the second section of the support structure further comprises a second central passage recess which has an opening of sufficient dimensions to allow a tubular component to, at least, be partially placed into the second central passage recess;
- wherein, when the first and second sections of the support unit are placed adjacent to each other, the first central passage recess and the second central passage recess together create said central passage;
- and
- wherein the first and second sections can be moved relative to each other so as to open up the central passage sufficiently to allow the support structure to move and fit around said tubular components.

- a first section;
- a second section;
- a first leg and a second leg projecting from the first section;
- a third leg and a forth leg projecting from the second section;
- a hinge;
- and
- a central passage of sufficient diameter to allow passage of the tubular components therethrough;
- wherein, when the first section and the second section are assembled together, said sections together are suitable to support said unit used to manipulate tubular components through a wellhead;
- wherein, when the first section and the second section are assembled together, said first leg, second leg, third leg and fourth leg support said unit used to manipulate tubular components through a well head in an upright manner on the rig floor;
- wherein the first section of the support structure further comprises a first central passage recess which has an opening of sufficient dimensions to allow a tubular component to, at least, be partially placed into the first central passage recess;
- wherein the second section of the support structure further comprises a second central passage recess which has an opening of sufficient dimensions to allow a tubular component to, at least, be partially placed into the second central passage recess;
- wherein, when the first and second sections of the support unit are placed adjacent to each other, the first central passage recess and the second central passage recess together create said central passage;
- wherein the first section and the second sections are connected together via the hinge at a pivot point, to allow the first and second sections to pivot with respect to each other around a substantially vertical pivot axis;
- wherein the first and second sections can pivot about said vertical axis so as to open up the central passage sufficiently to allow the support structure to move and fit around said tubular components.
