The invention concerns the field of shipbuilding. Claimed is a method for manufacturing a hull of a floating craft, during which a shell is applied on installed templates copying the contours of the hull of the floating craft, a reinforcement is applied on the formed surface, thereafter a composite matrix is applied. The surface of the shell can be additionally covered from the inside with a layer of liquid rubber. Thereafter, on the resulting surface is applied a reinforcement and a composite matrix.

Ultra-large marine submersible transport boats and arrangements for aqueous bulk liquids transportation, including fresh water and irrigation drainage, from specifically configured supply stations to specifically configured delivery stations. Boats present rigid hydrodynamic shaped double-walled submersible hulls incorporating a plurality of inside-reinforced impervious ballast chambers and also present radial reinforcing elements and hollow interior cavities that enclose collapsible bulk liquid bladders for transporting bulk liquids. Hulls can be made of reinforced concrete. Hull openings permit seawater circulation, avoiding transportation of bulk ballast seawater. Submersible cruising reduces structural loads and drag. An on-board hydro-pneumatic ballasting system adds to and removes reusable hull ballast water from, the ballast chambers controlling the hull's depth, pitch, and roll. Propulsion, steering capabilities, and detailed arrangements and methods for loading, unloading, and transporting bulk liquids are presented. Hull manufacturing is done on marine floating platforms using onshore precast panels. Maintenance and end of life procedures are detailed.

A composite floating dock system comprised of one or more dock float components, with each dock float component having a dock frame and one or more floats attached thereto, with each of the dock float components constructed of fiberglass reinforced plastic into a single monolithic unit, and being ballasted with encased concrete.

The present invention relates to a floating support structure (1) provided with a main floater (2) and with a heave plate (3). Heave plate (3) comprises a section varying with depth. Furthermore, heave plate (3) has a minimum horizontal section Sd1 greater than horizontal section Sc of main floater (2).

The present invention is a floating support structure (1) provided with a main floater (2) and a heave plate (3). The heave plate (3) comprises a single row of orifices (4), substantially parallel to the periphery of the heave plate.

A floating platform (1) to support offshore structures intended to generate electricity, this platform comprising a load-bearing support base (2) made of concrete and defining a longitudinal axis (L), this support base (2) being provided with three vertices (3, 4, 5) and an intermediate point (6) located near its geometric center; a plurality of vertical bodies (8) made of concrete which extend from the support base (5) at said vertices (3, 4, 5) and at the intermediate point (6). A vertex (3) of the load-bearing support base (2) is arranged in a longitudinally forward position with respect to the other two vertices (3, 4) and the load-bearing support base (2) comprises a pair of main connection arms (18) suited to directly connect the vertex (3) in a longitudinally forward position with respect to the other two vertices (3, 4) so as to define a substantially arrow-like shape in plan view. A method for the construction of a floating platform (1) to support offshore structures intended to generate electricity.
