Abstract
Method and apparatus for cribbing a floating roof included in a storage tank whereby a first and a first opposite force are applied between a floor in the storage tank and an internal surface of the floating roof. An additional set of forces are also provided and are constrained according to the first and first opposite force, not only in magnitude, but in position. By constraining these forces to be applied orthogonally to the floating roof, horizontal shear forces can be resisted thus reducing the likelihood of failure of a cribbing unit.
Claims20
A cribbing system, comprising:
- a first vertical riser;
- a second vertical riser;
- a first horizontal base span;
- a first horizontal cap span;
- a first base member having a first vertical base receptacle and a first horizontal base receptacle, wherein the first vertical base receptacle is configured to selectively receive the first vertical riser and the first horizontal base receptacle is configured to selectively receive the first horizontal base span;
- a second base member having a second vertical base receptacle and a second horizontal base receptacle, wherein the second vertical base receptacle is configured to selectively receive the second vertical riser and the second horizontal base receptacle is configured to selectively receive the first horizontal base span;
- a first cap member having a first vertical cap receptacle and a first horizontal cap receptacle, wherein the first vertical cap receptacle is configured to selectively receive the first vertical riser and the first horizontal cap receptacle is configured to selectively receive the first horizontal cap span;
- a second cap member having a second vertical cap receptacle and a second horizontal cap receptacle, wherein the second vertical cap receptacle is configured to selectively receive the second vertical riser and the second horizontal cap receptacle is configured to selectively receive the first horizontal cap span;
- and
- a grounding strap having a first end and a second end, wherein the first end of the grounding strap is coupled to one or more of the first vertical riser, second vertical riser, first horizontal base span, first horizontal cap span, first base member, second base member, first cap member, and second cap member, and wherein the first vertical riser, second vertical riser, first horizontal base span, first horizontal cap span, first base member, second base member, first cap member, and second cap member are electrically conductive.
