Abstract

A foundation includes connection points. The connection points are configured to permit components to be connected to the foundation and permit loads to transfer from the components into the foundation. The foundation may be a suction anchor.

First claim

The invention claimed is:

1. A system comprising:
a first foundation and a second foundation of different sizes, lengths and/or geometries,
wherein:
each of the first foundation and the second foundation comprises connection points;
the connection points of the first foundation are configured to permit first components to be connected to the first foundation and permit first loads to transfer from the first components into the first foundation;
the connection points of the second foundation are configured to permit second components to be connected to the second foundation and permit second loads to transfer from the second components into the second foundation; and
the connection points of the first foundation and the connection points of the second foundation are located in the same position relative to each other and/or the connection points of the first foundation and the connection points of the second foundation are the same size, such that the connection points in the first foundation and the connection points in the second foundation are standardized;
the first foundation is part of a first assembly;
the second foundation is part of a second assembly;
the first components are part of the first assembly; and
the second components are part of the second assembly.

2. The system according to claim 1 , wherein each of the first foundation and the second foundation is a suction anchor.

3. The system according to claim 1 , wherein:
the connection points of the first foundation are additional parts that protrude from the first foundation to provide an attachment point for the first components; and
the connection points of the second foundation are additional parts that protrude from the second foundation to provide an attachment point for the second components.

4. The system according to claim 1 , wherein at least one of the connection points of the first foundation and the connection points of the second foundation has an adjustable height.

5. The system according to claim 1 , wherein each of the connection points of the first foundation and the connection points of the second foundation comprises or is arranged to be connected to a guide device.

6. The system according to claim 1 , wherein:
the connection points of the first foundation are stronger than adjacent parts of the first foundation; and
the connection points of the second foundation are stronger than adjacent parts of the second foundation.

7. The system according to claim 1 , wherein:
at least one of the connection points of the first foundation is at an outer perimeter of the first foundation; and
at least one of the connection points of the second foundation is at an outer perimeter of the second foundation.

8. The system according to claim 1 , wherein:
at least one of the connection points of the first foundation extends beyond a top of the first foundation; and
at least one of the connection points of the second foundation extends beyond a top of the second foundation.

9. The system according to claim 1 , wherein:
the connection points of the first foundation are at equally spaced locations around an outer perimeter of the first foundation; and
the connection points of the second foundation are at equally spaced locations around an outer perimeter of the second foundation.

10. The system according to claim 1 , wherein:
the connection points of the first foundation are integral with the first foundation; and
the connection points of the second foundation are integral with the second foundation.

11. The system according to claim 1 , wherein:
at least one of the connection points of the first foundation has a profile configured to permit the first loads to transfer from one of the first components and/or lock the one of the first components; and
at least one of the connection points of the second foundation has a profile configured to permit the second loads to transfer from one of the second components and/or lock the one of the second components.

12. The system according to claim 1 , wherein:
each of the connection points of the first foundation comprises a base portion integral with the first foundation and a connection portion to which one of the first components can be attached; and
each of the connection points of the second foundation comprises a base portion integral with the second foundation and a connection portion to which one of the second components can be attached.

13. A method comprising providing the system of claim 1 .

14. A system comprising:
a first foundation and a second foundation of different sizes, lengths and/or geometries,
wherein:
each of the first foundation and the second foundation comprises connection points;
the connection points of the first foundation are configured to permit first components to be connected to the first foundation and permit first loads to transfer from the first components into the first foundation;
the connection points of the second foundation are configured to permit second components to be connected to the second foundation and permit second loads to transfer from the second components into the second foundation;
the connection points of the first foundation and the connection points of the second foundation are located in the same position relative to each other and/or the connection points of the first foundation and the connection points of the second foundation are the same size, such that the connection points in the first foundation and the connection points in the second foundation are standardized;
the first foundation is part of a first assembly; and
the second foundation is part of a second assembly,
wherein the system further comprises:
at least one first guide device for connection to at least one of the connection points of the first foundation such that one of the first components can be attached to the at least one first guide device, the first loads can be to the first foundation through the at least one guide first device, the one of the first components can be guided toward a correct position and orientation on the first foundation by the at least one first guide device, and/or first guide wires can be attached to the at least one first guide device during an installation procedure; and
at least one second guide device for connection to at least one of the connection points of the second foundation such that one of the second components can be attached to the at least one second guide device, the second loads can be to the second foundation through the at least one guide second device, the one of the second components can be guided toward a correct position and orientation on the second foundation by the at least one second guide device, and/or second guide wires can be attached to the at least one second guide device during the installation procedure.

15. The system according to claim 14 , wherein:
the at least one first guide device includes a plurality of first guide devices, and one of the plurality of first guide devices protrudes further from the first foundation than another of the plurality of first guide devices; and
the at least one second guide device includes a plurality of second guide devices, and one of the plurality of second guide devices protrudes further from the second foundation than another of the plurality of second guide devices.

16. The system according to claim 14 , wherein:
the first foundation comprises a first fine alignment device, wherein the at least one first guide device is configured to initially guide the one of the first components toward the correct position and
