Abstract

A segmented jacket construction is proposed. The segmented jacket construction is for a foundation for a wind turbine installation. The segmented jacket construction has at least two grid segments, which are connected to each other by joints. The joint has two tubular jacket modules, which are bonded by a grouting material.

Claims

1. A segmented jacket construction, comprising:

a joint; and

at least two grid segments connected to each other by the joint,

wherein the joint comprises two tubular jacket modules,

wherein the two tubular jacket modules are bonded by a grouting material,

wherein a first tubular jacket module of the two tubular jacket modules comprises a larger diameter than a second tubular jacket module of the two tubular jacket modules, the second tubular jacket module being inserted into the first tubular jacket module,

wherein a circular space between the first and second jacket modules is filled with the grouting material,

wherein the two tubular jacket modules are angulate,

wherein the joint is covered by a sleeve, and

wherein an inner surface of the sleeve is profiled.

2. The segmented jacket construction according to claim 1, wherein a first tubular jacket module of the two tubular jacket modules comprises an inner protrusion to support a second tubular jacket module of the two tubular jacket modules.

3. The segmented jacket construction according to claim 2, wherein a plurality of inner protrusions are provided as support knees.

4. The segmented jacket construction according to claim 1, wherein the sleeve comprises an inlet for injecting the grouting material.

5. The segmented jacket construction according to claim 1, wherein an inner surface of the two tubular jacket modules is profiled.

6. The segmented jacket construction according to claim 1, wherein the segmented jacket construction is for a foundation for a wind turbine installation.

7. A foundation for a wind turbine installation, comprising:

a segmented jacket construction according to claim 1.

8. A segmented jacket construction, comprising:

a joint; and

at least two grid segments connected to each other by the joint,

wherein the joint comprises two tubular jacket modules, and

wherein the two tubular jacket modules are bonded by a grouting material,

wherein the joint is covered by a sleeve,

wherein the sleeve comprises an inlet for injecting the grouting material, and

wherein an inner surface of the sleeve is profiled.

9. The segmented jacket construction according to claim 8, wherein a first tubular jacket module of the two tubular jacket modules comprises an inner protrusion to support a second tubular jacket module of the two tubular jacket modules.

10. The segmented jacket construction according to claim 9, wherein a plurality of inner protrusions are provided as support knees.

11. The segmented jacket construction according to claim 8, wherein an inner surface of the two tubular jacket modules is profiled.

12. The segmented jacket construction according to claim 8, wherein the two tubular jacket modules are angulate.

13. The segmented jacket construction according to claim 8, wherein the segmented jacket construction is for a foundation for a wind turbine installation.
