Abstract
An offshore structure (1) with tubular braces (110) that are joined by joints (125) at nodes (120). The tubular braces (110) may be made of steel. The joint (125) is formed by means of casted concrete or grout in a receiving joint volume (150) in one or both of the braces (110). Also disclosed is a a keel structure formed by braces (110) and joints (125) as outlined and a combination of a wind turbine and such offshore structure (1).
Claims15
An offshore structure (100) comprising at least two tubular braces (110A, 110B) with end parts (112A, 112B) of the braces (110A, 110B) joined by a joint (125) at a node (120) of the structure, wherein the tubular braces (110A, 110B) are optionally made of steel, and wherein the joint (125) is formed by means of hardened casting material, for example concrete or grout, in a receiving joint volume (150) in one or both end parts (112A, 112B) of the braces (110A, 110B) that form the node (120).
The structure (1) according to any one of the preceding claims, wherein the casting material comprises cement.
The structure according to any one of the preceding claims, wherein the structure is a floating offshore structure.
The structure according to any one of the preceding claims, in combination with an offshore wind turbine, wherein the wind turbine is supported by the structure.
