An item of equipment for producing a floating photovoltaic installation, of modular design, which includes float modules constituted, in whole or in part, of plastic casings, confining an air volume, having a neck with an opening, blocked by a stopper, structural modules, support elements, and possibly, connecting modules. The structural modules and/or the connecting modules include lugs intended to face one another for the assembly of the modules, and wherein the float modules are configured such that the assembly of the lugs facing one another is obtained, in whole or in part, by inserting the neck through the lugs, the stopper not present, then locking the assembly by the placing of the stopper blocking the opening of the neck.

A vessel and method for the production, transport, and deployment of additively-manufactured objects is disclosed, where the vessel and method permit the efficient fabrication and deployment of additively manufactured objects on and into a body of water. Additively manufactured objects are manufactured and/or fabricated directly on a vessel which can lower itself into the water, thereby facilitating the deployment of said objects.

A floating structure based on the tensegrity principle is described. A planar closed loop structure (1700) has a plurality of beams (300) and a plurality of beam adapters (700). Each of the plurality of beams (300) is formed by coupling multiple n-strut twisted prism units. Each of the multiple n-strut twisted prism units includes n-sided planar polygonal surfaces on opposite sides through which the respective n-strut twisted prism unit is coupled to another n-strut twisted prism unit or a beam adapter. Each of the plurality of beam adapters (700) is an m-strut twisted prism unit having planar polygonal side faces for coupling to an n-sided planar polygonal surface of a beam (300).

A floating wind turbine farm 230 includes a plurality of anchors 20/202/204/206/208 fixed in or on a bed of a body of water. A plurality of floating wind turbine platforms 10 is deployed in the body of water, each of the floating wind turbine platforms 10 having one or more mooring lines 200/212 that extend between, and are attached to, the floating wind turbine platform 10 and one of the anchors 20/202/204/206/208. Each anchor 20/202/204/206/208 is configured to receive two or more mooring lines 200/212, wherein each of the mooring lines 200/212 are from a different one of the plurality of floating wind turbine platforms 10.

An off-shore wind turbine system is assembled using a platform or jack-up vessel, and a first base anchored to the seafloor at a blade assembly off-shore location. A buoyant tower is attached to the first base. A crane provided on the platform or jack-up vessel is used to lift blades and blades, which are then coupled to a turbine held in a nacelle provided at the top of the buoyant tower. The buoyant tower, the nacelle, and the blades are detached from the first base. The buoyant tower, the nacelle, and the blades are towed to a wind farm and connected to a second base provided in the wind farm. The buoyant tower, the nacelle, and the blades are further stabilized using mooring lines spanning between the buoyant towers and other bases provided in the wind farm. The first base and/or the second base include anti-rotation features.
