发明名称 RIGID JACKET OF AN OFFSHORE PLATFORM HAVING A QUADRAPOD STRUCTURE
摘要 A launchable rigid jacket (10) of an offshore platform has a structure including an exterior framing and a plurality of cross-sectional frame sections (46a,46b,46c,46d). The exterior framing has four outside legs (24a,24b,24c,24d), which are spaced apart to define four corners of a trapezoidal cross section. The jacket (10) also includes two launch runners (60a,60b) mounted on adjacent parallel outside legs. The cross-sectional frame sections are horizontally positioned at periodic intervals along the height of the jacket (10) and each has a plurality of members, which interconnect the four outside legs and are part of the exterior framing. The exterior framing in total defines an integral launch box for the jacket (10). A plurality of perpendicularly oriented conductors (56) pass through each cross-sectional frame from the base (12) to the top (14) of the jacket (10) and conductor guides (58) connected to the respective frame sections slidably engage the conductors (56) to laterally support them.
