Description

Vertical manufacturing method of marine floating platform

The invention relates to a method for manufacturing a marine floating platform, in particular to an upright manufacturing method for converting a 90 degree ocean floating platform, so that a large marine floating platform can still be produced within a limited shipyard dry dock width.

In recent years, the development of marine energy driven by offshore wind power has been rapidly developed. In shallower waters, the use of bottom-mounted wind power generation fixed to the seabed is the most common. When the water depth is large, it is more economical to use floating wind power. Floating wind power needs to build a floating platform first, usually built by shipbuilding dry dock. If the design needs, the main size of the floating platform may exceed about 50 meters, which is larger than the dry dock width used by the existing general shipbuilding industry. In-house economic production requires additional investment in the construction of larger dry docks or slides for production, resulting in higher costs.

In order to enable the ocean floating platform to be economically produced in a limited space of the dry dock, the present invention provides an upright manufacturing method for a marine floating platform. One of the marine floating platforms of the present invention includes at least three floating cylinders, each of which is respectively above The lower two layers of the tubular member and the oblique member are connected, and a damping plate is disposed under each of the buoys. The marine floating platform is configured such that all the buoys float horizontally on the sea surface at the same time and the damper plate is not in the water, and then anchored to the fixed position of the seabed by the anchor chain, so that the marine floating platform can be used as a base for the wind turbine installation. Or as a floating platform for the installation of marine energy production equipment. The marine pontoon includes a total side length dimension of the underlying damper plate or a total vertical dimension perpendicular to the total side length of more than 50 meters, which cannot be arranged horizontally in a general shipyard dry dock (width is less than 50 meters) put up. If the height of the pontoon is less than the width of the dry dock (about 50 meters), use the upright posture of step A to 90 degrees to set the two pontoons as the bottom on the dock of a dry dock, with the third pontoon positioned above. In this way, the upright state can be manufactured in a limited width of the dry dock for shipbuilding.

When constructing in the dry dock, if the height of the dock is low, the height of one side of the damper plate can not be built first. After completion, proceed to step B to open the dry dock into the dock door. The whole floating platform is raised in an upright manner. And towed out the dry dock, and then in the port, in an appropriate way, from the upright posture to the horizontal posture, floating normally on the sea surface, and then using underwater screwing or underwater welding, the damping plate is missing. Part of the completion is completed.

It can be seen from the above that after the tubular rod member and the diagonal rod member are connected between the pontoons of the marine floating platform of the present invention, if the ocean pontoon includes the damper plate side below if the side length is greater than 50 meters, It cannot be constructed horizontally in a dry dock of general shipbuilding (about 50 meters in width). If the total height of the pontoon is less than the width of the dry dock (about 50 meters), the two pontoons are set to the bottom in a vertical attitude of 90 degrees, and placed on the dry dock dock, and then produced in an upright state. It can be manufactured in a limited space of the dry dock. After completion, the dry dock is filled according to the normal procedure, the dock door is opened, and the whole floating platform is erected, floated and towed out of the dry dock, and then properly in the harbor or other calm waters. The method, from the erect posture, is turned to a horizontal posture, and floats normally on the sea surface. In this way, the vertical manufacturing method of the marine floating platform of the present invention can be economically produced in the dry dock without additional investment in building a larger dry dock or sliding table for production without increasing the cost of constructing the marine floating platform.
