Benefits of technology

The invention provides a way to install a platform topside for an offshore platform that reduces the effort required to erect the platform. The structure features protrusions on both sides of the center part and / or side parts that connect to the substructure. The structure also has a cross-sectional shape that improves its stability and reduces the amount of buoyancy needed. The legs have a cone on their bottom to aid in connecting them to the substructure, which is pre-configured with a hollow-cylindrical pile or connection unit. Overall, the invention simplifies the installation process and makes offshore platforms more efficient.

Problems solved by technology

The installation of the known offshore platforms is complex.

Embodiment Construction

[0067]While this invention may be embodied in many different forms, there are described in detail herein a specific preferred embodiment of the invention. This description is an exemplification of the principles of the invention and is not intended to limit the invention to the particular embodiment illustrated.

[0068]According to FIGS. 1 and 20, an offshore platform 1 comprises a substructure 2, which is deposited on the ocean floor 3. The substructure 2 forms with piles 4 the foundation structure of the offshore platform 1. The piles 4, also called “nails”, are driven into the ocean floor 3, in order to establish a pile foundation and to anchor the substructure 2 on the ocean floor 3. The piles 4 serve to transfer loads from the platform topside 5. The piles 4 are preferably circular-cylindrical. They are preferably hollow-cylindrical.

[0069]The platform topside 5 is a supporting structure, which is arranged in the area above the surface of the water 6 and outside the sphere of infl...

Abstract

A platform topside for an offshore platform including a self-floating superstructure with a stable floating position, projections on the superstructure, means for mounting legs in an upright arrangement in the projections, wherein the projections and the means for mounting legs are arranged above the water line or not far below the water line, means for displacing the legs in the longitudinal direction of the legs in the means for mounting and means for fixing the legs in their positions in the means for mounting.

Description

CROSS-REFERENCE TO RELATED APPLICATIONS[0001]Not applicableSTATEMENT REGARDING FEDERALLY SPONSORED RESEARCH[0002]Not applicableBACKGROUND OF THE INVENTION[0003]The invention relates to a platform topside for an offshore platform and to a method for installing a platform topside for an offshore platform.[0004]Offshore platforms are artificial platforms in the ocean, which mostly serve to house technology and accommodations for personnel. The invention relates in particular to offshore platforms for collecting electrical energy from offshore wind turbines and its transfer to an onshore station in the rectified or unrectified state. Such offshore platforms are also called transformer platforms. The invention is also applicable to other offshore areas.[0005]Offshore platforms with a substructure made of a tubular steel frame are already known. The tubular steel frame is towed to the setup site on a barge using a tugboat. There, it is lowered to the ocean floor by means of floating crane...
