The invention discloses a deck supporting combination device for floating installation of an ocean engineering upper module, which is characterized by comprising a barge, at least three three-degree-of-freedom stable module devices, a plurality of hydraulic jacks and an upper module, and the three-degree-of-freedom stable module devices and the hydraulic jacks are installed on a deck of the barge. The three-degree-of-freedom stable block device is driven by three hydraulic cylinders, the upper ends of the three hydraulic cylinders are connected with the lower side of the movable platform through first ball-and-socket joint structures respectively, and the upper side of the movable platform is connected with and supports an upper block through a second ball-and-socket joint structure. According to the invention, the movement of the upper module is controlled through the active control position three-degree-of-freedom stable module device and the hydraulic jack support, and the movement of the barge generated by waves in the mounting process is compensated, so that the upper module can be connected with the offshore pile foundation more safely.
Description
technical field [0001] The invention belongs to the technical field of marine engineering installation, and in particular relates to a deck support combination device suitable for floating-over installation of marine engineering upper blocks under high sea conditions. Background technique [0002] Float-over method is a method of offshore installation of large-scale modules. It places the modules on the upper part of the offshore platform on a barge and sails above the pile foundation. The modules are placed on the foundation of the pile foundation by adjusting the ballast of the barge. The method avoids the large-scale floating crane installation ship operation, and has the characteristics of large installation weight, short operation time, safe and convenient operation, and the like. However, the floatover method needs to be carried out in a strict time window, which limits the use of this method in high sea conditions. The motion compensation method can compensate the co...
