In one embodiment, a female wedge mount is attached to a first surface vehicle. The female wedge mount has a concave contact surface including three or more female contact surface segments an at least two female wedge slots. A male wedge mount is attached to the second surface vehicle. The male wedge mount has a convex contact surface including three or more male contact surface segments and at least two male wedge slots that are aligned with the at least two female wedge slots, respectively, when the convex contact surface of the male wedge mount and the concave contact surface of the female wedge mount are in aligned contact with one another to form an adjacent connection between the first and second surface vehicles. A mechanism includes at least two pins that are movable along the at least two male and female wedge slots, respectively, between unlocked and locked positions.

A floating tunnel shore connecting system, a floating tunnel and a floating tunnel construction method are disclosed, where the design method of the floating tunnel is to apply axial tension along one end or two ends of a tube body respectively; The floating tunnel shore connecting system comprises a joint section located at the end of the tube body, which can move along the axial direction and is connected with a tension device for applying axial tension; The floating tunnel comprises a tube body and a hollow cavity, wherein the tube body comprises a floating section and a shore connecting system at two ends, and both joint sections are provided with tension devices. The design method and structure of the floating tunnel provided by the present invention, by applying the axial tension of the tube body, can significantly increase the horizontal stiffness and vertical stiffness of the whole floating tunnel tube body, improving the natural vibration frequency of the tube body, and the safety and reliability of the floating tunnel are improved; It is beneficial to the long-term use of the cable and the foundation anchored on the seabed or the riverbed. The construction risk is also lower, and the cost is also lower, which effectively saves the construction cost, and is easy to implement and popularize the project.

A water walking stage system is disclosed. The water walking stage system according to embodiment of the present invention comprises: opposite side floating bodies, each having a structure which is filled with gas or a foam resin material and thus floats on the surface of water and including a safe connector embedded inside thereof; a walking stage connected under the opposite side floating bodies to form a footing and positioned to be immersed in the water below the surface of water; rails for connecting the opposite side floating bodies to both sides of the walking stage, respectively; and a fixing rod installed on the ground and connected to the safe connector mounted inside of each of the opposite side floating bodies, thereby fixing the positions of the opposite side floating bodies, wherein the opposite side floating bodies, the walking stage, and the rails constitute one module unit by an integrated assembly structure.

A floating ocean platform stabilized in position by energy produced from wave energy. In one embodiment, the platform may be used to support a roadway to build a floating bridge. The platform may also include a wave break mechanism for additional stability and may submerge for storm survival. The platform may be constructed in modules to permit reconfiguration and management of resources. In other embodiments, the platform may support communities. The bridge may also provide transmission lines for conducting wave generated electricity back to the mainland.

A floating dock retention device. A flexible tether is adapted to retain a floating section to an adjacent structure, with a length defined between first and second positions along the flexible tether. A first clamp is affixed at the first position of the flexible tether, and a second clamp is affixed at the second position of the flexible tether. A drawbar spring with first and second ends is affixed to the first clamp at the first end and to the second clamp at the second end. The drawbar spring has a longer length when the drawbar spring is in a limit of its tension, and a shorter length when the drawbar spring is in a resting position. The longer length is no longer than the length between the first and second positions of the flexible tether, and the shorter length produces slack in the length between the first and second positions of the flexible tether.
