ABSTRACT:
An offshore structure is disclosed for placement on a sea floor foundation located in a body of water containing moving ice masses and water waves. The offshore structure has a foundation base which contacts the sea floor foundation and at least three stepped stages which are stacked above the foundation base. Each stage has an outer hull to engage moving ice masses and water waves. Additionally, each stage has an outer horizontal diameter which is smaller than the outer horizontal diameter of the stage immediately below it.
