A watercraft assembly is provided. The watercraft assembly includes a fuselage extracted from a used aircraft, wherein the fuselage has a base that is configured to be disposed above a waterbody. The watercraft assembly further include a plurality of coupling members coupled to the base of the fuselage. The plurality of coupling members is equally distributed on opposing sides of the fuselage and each coupling member includes a staircase that is aligned towards a first axis, which is perpendicular to a longitudinal axis of the fuselage. The watercraft assembly further include a plurality of side vessels coupled to the plurality of coupling members. Each side vessel of the plurality of side vessels may be configured to be disposed on the waterbody and bear a weight of the fuselage above the waterbody, via the plurality of coupling members.

Disclosed is a bionic fish single-degree-of-freedom modular structure based on a cam mechanism. The bionic fish single-degree-of-freedom modular structure comprises a plurality of modules which are sequentially connected, wherein the foremost one of the modules is a fish head module, and the last one of the modules is a fish tail module; each module in the modules comprises a rack, a rotating shaft is arranged in the center of the rack in a penetrating mode, the second end of the rotating shaft of the previous module is connected to the first end of the rotating shaft of the next module through a universal coupling, the next module is connected with the previous module through a swing connecting piece, and the effect that the modules swing in a plane is achieved.

A floating foundation includes a plurality of unit modules that can be fabricated in an efficient manner and then assembled, on shore or afloat near the deployment location. The floating foundation can be applied to various offshore energy systems, such as wind power generation, and in deployment locations with limited infrastructure.

Topside modules are fabricated at a production site using as a foundation for installation a gravity-based structure (GBS), which can stay afloat during water transportation. Modules fabrication includes: Stage I, fabrication of components; Stage II, fabrication of nodes from the components; Stage III, fabrication of sub-assemblies from the nodes; Stage IV, shotblasting and painting of assemblies; and Stage V, assembling modules from the assemblies. Then modules transportation, movement to their seats on the GBS and their integration include: Stage VI, moving the modules to an area near the dock using self-propelled vehicles. Stage VII, moving each module onto guides of a lifting system installed in a dry dock. Stage VIII, lifting each module until lifting system guides are connected with GBS top slab guides. Stage IX, moving each module to its seat on the GBS, installed on the GBS and integrated with other modules and the GBS.
