Proposed is a wave-dissipating block including: a body placed on a seabed perpendicularly thereto and having a shape of a polygonal column, a cylinder, an oval column, or a cross-shaped column; male coupling protrusions formed on a first surface of the body in a height direction thereof and on a surface opposite to the first surface, respectively; female coupling grooves formed in a second surface of the body in the height direction thereof and in a surface opposite to the second surface, respectively; a habitat part configured as a space defined at a center portion of the body or a portion of the body; a dividing plate provided as a plate dividing the habitat part into habitat parts; a through hole formed in the dividing plate; and a space part having a space defined between multiple bodies of wave-dissipating blocks connected adjacently to each other.

A floating breakwater and wind energy integrated system used for offshore aquaculture. The system contains the wind turbine system, the floating breakwater system, and offshore aquaculture system. The combination of wind turbine, floating breakwater system and offshore aquaculture system makes full use of the floating breakwater, thus decrease the wave load on the floating cage. In addition, the floating breakwater offers a supporting platform to the floating wind turbine, which effectively reduces the costs of the wind turbine. Meanwhile, a power autarkic offshore aquaculture system may be realized by using the electrical energy generated by the turbine. Compared with the simple offshore aquaculture system, the utilization rate of the sea per unit becomes even higher while the costs of the floating wind turbine becomes even lower.

A floating breakwater structure is described. The structure includes a floating platform disposed at a water surface and a mooring system. The floating platform has one long side for facing a shore and another long side for facing a sea-horizon. The mooring system includes at least one pair of side anchors located on the seabed at one long side of the buoyancy platform, and at least one another pair of side anchors located on the seabed at the other long side of the floating platform. The mooring system also includes at least two pairs of crossing mooring spring-lines linked at one end to the floating platform. Each pair of the crossing mooring spring-lines is linked at one end to the corresponding long side of the of the floating platform and at another end to the corresponding pair of the side anchors.

An apparatus and methods for a modular inflatable dock portion are provided for being assembled into various desirable arrangements over waterways. The modular inflatable dock portion comprises an envelope having a shape for floating on water. The envelope preferably is comprised of a pliable, lightweight, water-resistant material. Hinges are disposed along sides of the envelope and configured for joining with adjacent modular inflatable dock portions. The hinges allow movement between joined dock portions to accommodate hydrodynamic phenomena typically encountered by floating docks. A chamber within the envelope is configured for being inflated with air or other suitable gas. Drop stitches are disposed within the chamber and configured to maintain an overall shape and size of the envelope. The drop stitches may be arranged in the envelope in a manner that causes the inflatable dock portion to maintain a desired configuration regardless of internal pressure within the chamber.

The dock leveling system is a device to quickly and easily alter the height of the lake dock without necessitating getting into the water. The system can be installed into existing docks, or could potentially be sold with new docks. The system accomplishes the purpose of altering the height of the lake dock by the movement of a lower and upper clamp, each connected to the two foot threaded rod by an angle iron. Using a cordless drill, the top nut can be rotated clockwise or counter-clockwise. Clockwise movement of the top nut brings the two clamps together, raising the dock. Reversely, counter-clockwise movement of the top nut distances the two clamps from each other, lowering the dock frame.

A floating platform is attached to another object. The object may be fixed to the earth or it may be a floating object such as a floating dock or a vessel. The floating platform is held in horizontal position relative to the object to which it is attached, but vertical movement of the floating platform relative to the object is permitted. The object is connected to the floating platform by devices that have blades extending from. Each blade slidably engages a bracket, with the slidable blade permitting horizontal adjustment of the distance of the floating platform from the object during installation of the floating platform. Guide posts or piles slidably engage pile guides mounted to the object, permitting the floating platform to move vertically relative to the object, but fixing the floating platform's horizontal position relative to the object.

Disclosed is a fast-laid floating breakwater, which belongs to the field of ocean engineering and includes a foldable net cage, box-type rubber airbags, a counterweight system and a mooring system. The foldable net cage includes frames and a flexible net, and the frames divide the net cage into cabins. An air valve is provided at the upper part of each box-type rubber airbag and connected to the net, and the airbags are fixed in the cabins. The counterweight system is provided at the bottoms of the frames. The mooring system includes pull rings, mooring chains and anchors; the pull rings are connected to two sides of the lower end of each frame. The immersion depth of the breakwater can be regulated through weights of the frames and the counterweights, thereby fastening the breakwater laying.

A method of constructing an underwater concrete block structure includes assembling a plurality of concrete blocks into a concrete block assembly, forming a drilled borehole in the underwater ground under a concrete hole of the concrete block assembly, and forming a concrete column in the concrete hole and the drilled borehole, thereby greatly increasing the stability of the underwater concrete block structure.
