3. The compression plate associated with the seal and the slip bowl of the slip hanger of claim 1 , wherein the compression plate comprises a plurality of first sections to be located over the seal, wherein the seal comprises a plurality of second sections to be located over the slip bowl, wherein the slip bowl comprises a plurality of third sections, and wherein the compression plate, the seal, and the slip bowl are to be assembled together around a casing.
4. The compression plate associated with the seal and the slip bowl of the slip hanger of claim 1 , wherein the at least one bolt hole is adapted to receive at least one bolt, wherein the at least one bolt is adapted to receive a force and wherein the compression plate is adapted to compress at individual sections of the compression plate and is adapted to compress the seal underlying the compression plate.
5. The compression plate associated with the seal and the slip bowl of the slip hanger of claim 4 , wherein the compression plate is adapted to assert uniform downward clamping pressure through the individual sections of the compression plate.
6. The compression plate associated with the seal and the slip bowl of the slip hanger of claim 1 , wherein the at least one bolt hole that is between two further bolt holes, individual ones of the two further bolt holes being on either side of the at least one bolt hole.
7. The compression plate associated with the seal and the slip bowl of the slip hanger of claim 1 , further comprising:
a plurality of sections, wherein individual ends of individual ones of the plurality of sections assembled together form the at least one split.
8. The compression plate associated with the seal and the slip bowl of the slip hanger of claim 7 , wherein individual ends of individual ones of the plurality of sections comprise at least part of the at least one bolt hole.
9. The compression plate associated with the seal and the slip bowl of the slip hanger of claim 7 , wherein individual ones of the plurality of sections of the compression plate are assembled together over the seal, and wherein the at least one split of the bolt hole is in the offset position relative to the seal split of the seal.
10. A method for preparing a compression plate used with a seal and a slip bowl of a slip hanger, the method comprising:
machining the compression plate according to predetermined dimensions; and
drilling at least one bolt hole in the compression plate; and
splitting the compression plate at the at least one bolt hole, wherein the splitting provides at least one split in the at least one bolt hole, the at least one split being predetermined to enable arrangement of the compression plate with the at least one split in an offset position relative to a seal split of the seal and with the seal and the slip bowl being under the compression plate, and wherein the seal split is coincidental with a gland split of the slip bowl.
11. The method of claim 10 , wherein the splitting of the compression plate further comprises:
providing the at least one split through the at least one bolt hole to provide two halves for the compression plate.
12. The method claim 10 , wherein the splitting of the compression plate provides a plurality of sections for the compression plate to be associated together around a casing.
13. The method of claim 10 , further comprising:
threading the at least one bolt hole of a body of the slip hanger to enable the at least one bolt hole to receive at least one bolt, wherein the at least one bolt is adapted to receive a force and wherein the compression plate is adapted to compress individual sections of the compression plate to compress the seal underlying the compression plate.
14. A method for a compression plate used with a seal and with a slip bowl of a slip hanger, the method comprising:
providing the compression plate in a plurality of sections and associated together around a casing, wherein the plurality of sections join to form at least one split that is within at least one bolt hole of the compression plate;
arranging the at least one split of the compression plate in an offset position relative to a seal split of the seal, wherein the seal split is coincidental with a gland split of the slip bowl and
assembling the compression plate with at least one bolt through the at least one bolt hole.
15. The method of claim 14 , further comprising:
providing the seal over a lip of the slip bowl; and
providing the plurality of sections of the compression plate over the seal and over the slip bowl.
16. The method claim 14 , wherein the at least one split is through the at least one bolt hole to provide two halves for the compression plate, the two halves of the compression plate forming the plurality of sections.
17. The method of claim 14 , further comprising:
providing a preload to the at least one bolt to cause the compression plate to compress individual ones of the plurality of sections of the compression plate and to compress the seal underlying the compression plate.
18. The method of claim 14 , wherein the compression plate is adapted to assert uniform downward clamping pressure through the plurality of sections of the compression plate.
19. The method of claim 14 , wherein the at least one bolt hole that is between two further bolt holes, individual ones of the two further bolt holes being on either side of the at least one bolt hole.
20. The method of claim 14 , wherein individual ends of individual ones of the plurality of sections comprise at least part of the at least one bolt hole.
