8. The apparatus of claim 1 wherein the at least one radially moveable element is radially displaced by mechanical, electrical or electro-hydraulic means.
9. The apparatus of claim 1 wherein the apparatus is operated remotely.
10. The apparatus of claim 1 wherein the apparatus includes an override permitting operation by a remotely operated vehicle.
11. The apparatus of claim 1 wherein the tool is deployed by wireline.
12. The apparatus of claim 1 wherein the tool is deployed by slickline or coiled tubing.
13. The apparatus of claim 1 wherein the tool is adapted to be releasably connected to a plug by means of a standard wireline plug-retrieving tool.
14. The apparatus of claim 1 wherein the housing is adapted to be connected at a second end to a conventional landing string.
15. The apparatus of claim 1 wherein the housing is adapted to be connected at a second end to a subsea lubricator section or the like.
16. A housing adapted to be releasably connected at a first end to a horizontal xmas tree, the housing comprising:
a throughbore, and
an at least one axially moveable member, the at least one axially moveable member including an at least one radially movable element, the at least one radially movable element having an engagement surface, adapted to releasably engage with a complementary outer surface portion of a tool deployable within the housing throughbore.
17. The housing of claim 16 wherein the housing includes a housing land, adapted to engage with a tool land on deployment of the tool into the housing throughbore.
18. The housing of claim 17 wherein the housing land is mounted on the at least one radially moveable element.
19. The housing of claim 16 wherein the at least one axially moveable member is axially displaced by hydraulic means.
20. The housing of claim 16 wherein the at least one axially moveable member is axially displaced by mechanical, electrical or electro-hydraulic means.
21. The housing of claim 16 wherein the at least one radially moveable element is radially displaced by hydraulic means.
22. The housing of claim 16 wherein the at least one radially moveable element is radially displaced by mechanical, electrical or electro-hydraulic means.
23. The housing of claim 16 wherein the at least one axially moveable member is operated remotely.
24. The housing of claim 16 wherein the at least one axially moveable member is operated remotely.
25. The housing of claim 16 wherein the housing includes an override permitting operation of the at least one axially moveable member or the at least one radially moveable element or both by a remotely operated vehicle.
26. The housing of claim 16 wherein the housing is adapted to be connected at a second end to a conventional landing string.
27. The housing of claim 16 wherein the housing is adapted to be connected at a second end to a subsea lubricator section or the like.
28. A tool adapted to be deployed within a housing throughbore by an elongate support and adapted to be releasably connected to a plug, the tool comprising:
an outer surface, a portion of the tool outer surface being profiled to be releasably connected with a complementary engagement surface of an at least one radially moveable element.
29. The tool of claim 28 wherein the tool is deployable by wireline.
30. The tool of claim 28 wherein the tool is deployable by slickline or coiled tubing or any other known method of deploying tools downhole.
31. The tool of claim 28 wherein the tool is adapted to be releasably connected to a plug by means of a standard wireline plug-retrieving tool.
32. A method of setting a plug in a horizontal xmas tree, the method comprising:
deploying a tool, releasably connected to the plug, within a housing throughbore, the housing releasably connected to a horizontal xmas tree, the housing including an at least one axially moveable member, the at least one axially moveable member including an at least one radially movable element, the element having an engagement surface;
displacing the at least one radially moveable element until the engagement surface releasably engages with outer surface portion of the tool;
displacing the at least one axially moveable member towards the horizontal xmas tree until the plug is located in the correct position within the tree;
disengaging the engagement surface of the at least one radially moveable element from the tool outer surface portion;
