ABSTRACT:
A fixed, non-compliant, non-floating offshore platform subject to lower wave, wind, current, and rig loadings resulting from a configuration that supports the portion of the well casings that extend from near the seafloor to a deck level above the water surface using tension instead of intermediate lateral supports. Only the smallest one or two well casings among all those that comprise the well casing system are extended back from the seafloor, which further reduces the lateral loadings on the structure.
