A bar element as a construction element includes strips preferably produced from bamboo and is hollow at least in certain regions. The hollow interior is formed at least in certain sections as a hollow fillet achieved by a plastic and/or resin introduced into the bar elements, using a shaped body movable through the interior. Producing bar elements from interconnected strips ensures that although produced from a natural raw material, the bar elements have a reproducible outer cross section. Using a shaped body movable through the interior to produce the inner cross section also ensures a defined inner cross section of the bar elements, with the result that in turn connections between a plurality of bar elements that are defined by suitable connection elements can be formed. In this way, the bar elements make it possible to produce lattice works, grid constructions, frameworks or other desired structures and/or three-dimensional bodies.

A method for constructing a hull of an offshore structure includes (a) welding a plurality of plates together to form a plate assembly. The method also includes (b) passing the plate assembly through a rolling machine with the plate assembly in a vertical orientation. In addition, the method includes (c) bending the plate assembly into a cylinder during (b). The cylinder includes a pair of circumferentially adjacent free ends. Further, the method includes (d) welding the free ends of the cylinder together after (c) to form a cylindrical external wall.

A floating base comprising a shell constructed from a plurality of blocks reinforced using a plurality of tensile elements. The shell includes an inner space, a length, a width and at least one bulkhead disposed across the width along the length of the shell within the shell to strengthen the shell. In one embodiment, the shell further includes a spine disposed substantially at right angle to the at least one bulkhead to further strengthen the shell.

A flotation system for an offshore power generation platform comprises: multiple buoyant bodies each containing a high-pressure air and ballast water therein to create buoyancy; connecting members connecting the multiple buoyant bodies to each other; ballast water flowing tubes through which the ballast water contained in the multiple buoyant bodies flows with respect to each other; a high-pressure tank supplying the high-pressure air into the multiple buoyant bodies; a compressor replenishing air pressure present in the high-pressure tank; an equilibrium sensor sensing an equilibrium state of each of the multiple buoyant bodies and transmitting a signal; and a controller controlling, in response to the signal from the equilibrium sensor, an amount of air supplied from the high-pressure tank to the buoyant body and an amount of air discharged from the buoyant body.
