A longitudinal axis of each reverse osmosis membrane tube is substantially parallel with a longitudinal axis of the elongate chamber and the reverse osmosis membrane tubes are arranged around a passage.

A floating structure includes: a floating body including one or more buoyant bodies disposed around a structure; and a plurality of first support wires disposed between the structure and the floating body and configured to transmit the self-weight of the structure to the floating body. Each of the first support wires having: one end connected to the floating body; and another end connected to the structure below the one end.

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.

The invention relates to a structure (2) for supporting a wind turbine tower (1) provided with a housing (7) for fitting therein the foot of the tower (1), a main axis (?) being defined on the platform (2) which coincides with a main axis of the tower (1), and which comprises a body with a constant cross-section and internal walls (8) and intermediate walls (10) joined by internal radial ribs (11) perpendicular to the internal wall (8) whose plane passes through the main axis (?), such that at the intermediate wall (10) first joining nodes (12) are defined between the intermediate wall (10) and radial ribs (11), the intermediate wall (10) and an external wall (9) being joined by reticular ribs (14 and 15). This structure provides an optimal transmission of forces. The invention likewise relates to methods for manufacturing, assembling and installing the structure.

A system and method for mating equipment offshore to a spar buoy secured to a foundation without the use of a crane barge. The system comprises a floating vessel having a pair of forks defining a slot. A gimbal table, defining an opening, is positioned within the slot and connected to the vessel and a locking collar is mounted to the gimbal table. A mating member is attached to the spar buoy. The vessel is maneuvered to bring the spar buoy within the gimbal table opening. With the spar buoy positioned within the gimbal table opening, the locking collar is arranged and designed to releasably attach to the mating member of the spar buoy and restrict relative vertical motion between the spar buoy and the vessel while the gimbal table allows the floating vessel to roll and pitch without driving these motions into the spar buoy.

The present disclosure relates to an unmanned floating production unit (300) and method of installing a floating production unit comprising a deck structure (301) for mounting equipment for processing hydrocarbons, and a hull structure (302) formed from a first section (303) and a second section (306), wherein the second section (306) is wider than the first section (303). The floating production unit (300) according to the present disclosure can provide a compact unit, which has dimensions which can lead to a heave natural period outside an area of significant wave energy, and as a result, it has substantially reduced and improved hydrodynamic responses. The floating production unit is configured to be small and lightweight, and can be fabricated, launched and towed to the installation site in two parts, without the requirement for heavy lifting or construction machinery, thus lowering manufacturing costs. In addition, the two parts of the floating production unit can be joined together at the installation site using a buoyancy and ballasting based technique. The floating production unit is designed to be unmanned during routine production operations, thus ensuring operating costs are low.

A floating structure based on the 700 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).
