Transition element for connecting a tower to a jacket

摘要

A transition element between a jacket having four legs and a tower where the lower portion of the tower is fixed to a torsion plate that is connected to an upper portion of the legs. A brace extends from each leg. Each brace includes a strut. The strut has a first end portion and a second end portion. The strut is fixed to the upper portion of each leg and a plate that is fixed to the tower at a contact portion above the torsion plate. The planar plate is fixed to the tower in the circumferential direction and has a common axis of symmetry with the strut. The plate is fixed to the first end portion of the strut.

1. A transition element between a jacket and a tower in the form of a tubular member wherein the tubular tower has a lower portion connected to the transition element and the jacket has legs wherein the legs have an upper portion, the transition element comprising:
a torsion plate connected to the upper portion of the legs wherein the torsion plate is not designed to carry vertical forces from the tubular tower; a brace extending from each leg wherein each brace has a tubular strut having a first end portion and a second end portion wherein the second end portion is positioned opposite to the first end portion wherein the second end portion of the tubular strut is connected to the upper portion of each leg wherein the first end portion of the tubular strut has an interior formed by two slits extending axially into the tubular strut and further wherein the braces are designed to carry all axial force in the tubular tower; and a plate having a length defined between a first end and a second end wherein the first end is positioned opposite to the second end wherein the first end is connected to the tubular tower at a contact portion above the torsion plate wherein the plate is generally planar and further wherein the plate is connected to the tubular tower in the circumferential direction and the plate has a common axis of symmetry with a longitudinal axis of the tubular strut wherein the second end of the plate inserts into the two slits of the first end Portion and further wherein the second end of the plate is welded to the tubular strut.
