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 floater for a floatable wind energy power plant includes providing a first pre-assembled part with at least one first connection arrangement, providing a second pre-assembled part with at least one second connection arrangement, arranging the at least one first connection arrangement of the first pre-assembled part proximate to the at least one second connection arrangement of the second pre-assembled part so as to form a connection site which includes at least a part of the at least one first connection arrangement and at least a part of the at least one second connection arrangement, sealingly arranging an enclosure about the connection site so as to seal the enclosure against an ingress of water, and connecting the first pre-assembled part and the second pre-assembled part at the connection site. Each of the first pre-assembled part and the second pre-assembled part are floatable.

A modular floatable dock section comprises a fluid bladder having substantially flat top and bottom surfaces, and a perimeter around the top and bottom surfaces. The fluid bladder is designed for being selectively inflated in a deployed condition and deflated (collapsed) for transport and storage. A generally rigid continuous-surface deck is mounted adjacent the top surface of the fluid bladder, and defines a deck perimeter substantially coincident with the perimeter of the fluid bladder.

A floating marine structure which includes a first float disposed at the center and a plurality of second floats disposed around the first float, where the first float has a floating body made of a floatable material in a polygonal prism shape, a damping unit coupled to the bottom of the floating body at the center, having the same cross-section as the floating body, having a cross-sectional area larger than the cross-sectional area of the floating body, and reducing a shake of the first float in the sea, and at least one coupling hole formed at each side of the floating body. The second float has the same shape as the floating body and has coupling protrusions formed at sides facing the sides of the floating body and inserted in the coupling holes, and wherein the coupling holes are formed at alternate sides of the floating body.

A seagoing vessel having within its hull a plurality of longitudinally placed structural tubulars running the length of the tubeship. The tubulars are placed side by side and attached to each other and to the underside of the tubeship deck. According to one design, the tubeship hull is constructed upside down, layer by layer.
