Embodiment Construction

[0039] now refer to figure 1 , the support structure 1 shown therein comprises a sheath structure 2 comprising an upright integral column-like body 3 supported by a support foot assembly 4 consisting of four similar A supporting base unit 5 is formed. Each base unit 5 comprises a central tubular structure formed by an inner tube 5A and an outer tube 5B, considered in detail hereinafter, and a seabed or river bed engaging base 7 connected to the outer tube 5B. The outer tube forms part of an assembly 4 connected to the body 3 of the structure 2 via a substantially horizontal member 8 connected to the lower end region 9 of the body 3 of the structure 2 and at a position above the associated horizontal member 8 The inclined member 10 is itself connected to the main body 3 of the structure 2 .

[0040]Each seabed / river bed joint base is mounted to the lower end of the pipe 5B via a pivotal connection 11 which allows the base 7 to be raised or lowered relative to the outer tube 5...

Abstract

A method of installing a support structure (2) required to be installed in a sea or river bed SB, involving so constructing the support structure that is capable of being temporarily self standing on the sea or river bed (SB) prior to and throughout the carrying out of operations required permanently to anchor the support structure to the sea or river bed.

Description

technical field [0001] The present invention relates to the installation of support structures for seabed (or riverbed) installations that typically project above the sea (or river) surface. [0002] One possible application of the support structure is for supporting wind or water driven turbines, or wave energy power plants. [0003] In particular, the invention relates to methods of construction of support structures and their installation, regardless of their use. Background technique [0004] Although the support structure normally protrudes above the surface of the sea or river in which it is installed, it is desirable that after installation has been completed the upper part of the support structure can be removed so that in this case, The rest of the support structure, the so-called fixed parts, can remain completely underwater. [0005] It has been found that when setting up installation support structures, for example for underwater offshore seabed mounted turbine...
