A marine barrier has a plurality of column modules, each having a vertical column, and an impact net attached to and extending between the column modules. Each of the columns has four buoyant horizontal legs extending from its lower portion. A distal end of each of the legs is attachable to a distal end of a corresponding leg of an adjacent column module to form a series of diamond-shaped supports between the columns to support the columns and the impact net. When the barrier is floating in a body of water and a moving vessel impacts the impact net, the impact net deflects to transfer a force of the impact to one or more of the column modules, which in turn engage the water to transfer the force of the impact to the water, to arrest the motion of the vessel.

A breakwater (wave attenuation system) includes two horizontal tubes as buoyant members connected to one another, their cross-sections representing vertices of a triangle, whose legs are interconnecting struts. A perforated, submerged, ballast tube forms the third vertex. Wave motion is perpendicular to the length of the float tubes tethered to an anchor at the sea floor. A lead float tube rises in response to an approaching wave, often cutting off the wave crest, while a trailing float tube rises less and later as the wave passes. Asynchronous rising and falling of the leading and trailing, floating, top tubes rocks the breakwater, redirecting and dissipating wave momentum, energy, and water volume by rotating the assembly, thrashing the water.

A wave generation system may comprise a submerged platform. The submerged platform may be attached to the bottom of a body of water by cables or pilings. A wave generator may be coupled to the submerged platform. The wave generator may create waves above the submerged platform. The shape of the submerged platform may dictate the shape of the waves. The submerged platform may be adjusted by raising or lowering the submerged platform. The shape of the submerged platform may be adjusted by adjusting the pitch of various sections of the submerged platform. A portion of the energy in the generated waves may be transmitted beyond the submerged platform and dissipated by a surrounding body of water.

A transportable wave suppressor and sediment collection (WSSC) system positionable in deep water along a coastline of a body of water, having a plurality of sections, each section further including a base portion having an upper floor portion, a forward wall, rear wall and two sidewalls and an open bottom end portion for being positioned on a floor of the body of water; at least a pair of raised elongated members positioned on the upper surface of the upper floor of the base; an upper portion to be secured to the base portion, the upper section having a angulated front wall to receive the flow of water through a plurality of flow pipes as the water engages each section; at least a pair of elongated openings in the upper portion for receiving the raised elongated members positioned on the upper surface of the upper wall of the base to define a means for securing the base to the upper portion. There is further provided a one way valving element positioned on the rear end of each flow pipe, for allowing water containing sediments to exit the pipe at the rear wall, but preventing the water and sediments from returning through the flow pipe; and a spacer portion to be positioned intermediate the base portion and upper portion, the spacer portion including a plurality of flow pipes to allow water carrying sediment to the rear of the section.

Systems and methods of coastal erosion protection are disclosed, the system including at least one floating member, an anchor rode, an anchor, and a water-tolerant plant. The methods include placing at least one floating member in offshore waters, coupling an anchor rode to the floating member, coupling an anchor to the anchor rode, mooring the floating member to the sea floor, the mooring step further including placing the anchor on the sea floor and tightening the anchor rode until any slack in the anchor rode is removed, planting a water-tolerant plant in coastal soil, growing the water-tolerant plant to a pre-determined growth stage, and removing the floating member from offshore waters.

A wave resistant dock assembly may include a dock frame and a dock body. The upper dock body surface of the dock body may be flat or planar. At least one water discharge gap may be provided in the upper dock body surface. At least one water flow space may be provided in the lower dock body surface of the dock body. The water discharge gap in the upper dock body surface may communicate with the water flow space in the lower dock body surface. The water flow space may converge toward the water discharge gap. Accordingly, under high wave or storm conditions, water may flow from the body of water through the water flow space and discharge through the water discharge gap, eliminating or reducing water pressure against the dock body and reducing damage and premature wear to the dock body.

A wave attenuation device converts rotational wave energy of a water body into directional laminar flow. The wave attenuation device includes one or more semi-flexible panels having a second portion inclined with respect to a first portion and a third portion thereof. The semi-flexible panels are spaced apart with respect to each other in a vertical direction. The wave attenuation device includes a plurality of support pilings for supporting the one or more semi-flexible panels on a concrete bed position at a bottom of the water body. A highest point of the plurality of supports pilings is located at a mean low tide height of the water body. A space between the semi-flexible panels is open to flow of water, to enable delivery of food particles to oyster reefs located in the water body, while preventing sediment accretion.

A floating wave break apparatus to dissipate wave action in a body of water, the apparatus including three longitudinally extending wall members each with a plurality of through holes therein. The apparatus also includes a plurality of flotation members disposed between the longitudinally extending wall members. The wave break apparatus also includes at least one restraining member above the at least one flotation member for restraining the flotation member against upward translation as well as an anchor system with at least one winch and rope combination. The winches are mounted to the restraining member and the ropes are adjustable to restrain movement of the wave break apparatus.

Some embodiments relate to a power generation system. An example floating power generation system comprises: a vessel, the vessel including: a vessel frame, a hull around the vessel frame and defining fore and aft sections, and a deck supported by the vessel frame. A gas turbine may be provided on the vessel to generate electrical power from combustion of natural gas. An organic Rankine cycle (ORC) generator may be provided on the vessel to generate electrical power from heat recovery. A gas supply line may be provided on the vessel for supplying liquefied natural gas (LNG) to the gas turbine. A power supply subsystem may be provided on the vessel to receive electrical power from at least one of the gas turbine or the ORC generator and to supply power to at least one remote power sink that is away from the vessel.
