OFFSHORE STRUCTURE

摘要

The present invention relates to an offshore structure including a foundation (2) to be located on a sea floor and a base column (3) fixed to the foundation (2). The base column supports a second column (41) provided with an optional ice cone (5). In order to provide a lightweight and stabile foundation (2) the foundation is in the form of a unitary hollow frame structure (27) with an open bottom surface and with an open top surface arranged around the base column (3). The hollow frame structure (27) is composed of bulkhead elements (21, 22) attached to each other in order to form adjacent open cells (28) of the unitary hollow frame structure (27) with respective open bottom surface sections and respective open top surface sections. The present invention also relates to a method of manufacturing an offshore structure and a method for deploying an offshore structure on a sea floor.
