Abstract
An apparatus and methods for installation of an offshore platform for supporting equipment installations is provided. The apparatus includes a platform configured to support offshore equipment supported by a structure such as a modular column assembly. The modular column assembly can be comprised of main barrel joint bundles.
Claims19
An offshore installation comprising:
- a top platform having a weight and comprising a top surface and a bottom surface;
- a foundation configured to be disposed on a seafloor;
- a vertical column assembly comprising:
- a central longitudinal axis;
- a first end connected to the bottom surface of the top platform;
- a second end connected to the foundation;
- a first vertical support member extending from the first end to the second end, such that the vertical column assembly supports the weight of the top platform;
- and
- a plurality of tendons configured to extend from the top platform to the foundation;
- and
- a plurality of lateral supports configured to extend from the top platform to the seafloor.
