Abstract
Description
本發明係一種海洋浮台製造方法有關,尤其指一種轉成90度的海洋浮台的直立式製造方法,使在有限的造船乾塢寬度內,仍能生產大型海洋浮台。 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.
近年來以離岸風力發電帶動的海洋能源發展迅速展開,在較淺水域,使用固定於海床之底著式風力發電最為普遍,當水深較大,使用浮動式風力發電則較為經濟可行。浮動式的風力發電需要先建造浮台,通常利用造船乾塢建造,若因設計需要,浮台主要尺寸可能超過約50公尺,大於現有一般造船業使用的乾塢寬度,則無法在乾塢內經濟生產,因此需要另外投資建造更大型的乾塢或滑台來生產,使得成本提高。 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.
為使海洋浮台可在乾塢有限空間內經濟生產,本發明提供一種海洋浮台的直立式製造方法,本發明之一海洋浮台係包含有至少三個浮筒,每個該浮筒間分別以上下兩層管狀桿件及一斜向桿件相連接,每個浮筒下方設有一阻尼板。此海洋浮台係以所有浮筒同時水平漂浮在海面且該阻尼板皆沒於水中姿態操作,再以錨鍊繫泊於海床固定位置,使該海洋浮台可作為風力機安裝的基座,或係作為海洋能源生產設備的安裝浮台。該海洋浮台包含下方之阻尼板之總邊長尺寸或垂直於總邊長的總垂直尺寸大 於50公尺,無法以水平方式安排在一般造船的乾塢(寬度大約都小於50公尺)中建造。若該浮筒高度小於乾塢寬度(約50公尺),改採用步驟A轉90度之直立式姿態將兩個該浮筒設為底部置於一乾塢之塢墩上,以第三浮筒位在上方之方式,則此直立的狀態,可以在造船用的乾塢有限寬度內生產製造。 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.
在乾塢內建造時候,若為塢墩高度低,可以將阻尼板的一邊高度先不建造,完工後,進行步驟B,將乾塢進水塢門打開,整體浮台以直立方式,浮起並拖帶出乾塢,在港內再以適當方法,由直立姿態翻正為水平姿態,正常地浮於海面,再以水下以螺絲鎖接方式或是水下焊接方式,將該阻尼板缺少部分補做完成。 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.
由上述可知,本發明之該海洋浮台之各該浮筒間以該管狀桿件及該斜向桿件相連接後,該海洋浮台包含下方之該阻尼板邊長若大於50公尺,則無法以水平方式安排在一般造船的乾塢(寬度大約都小於50公尺)中建造。若該浮筒總高度小於乾塢寬度(約50公尺),改採用轉90度之直立式姿態將兩個該浮筒設為底部,並置於乾塢塢墩上,則以此直立的狀態生產,可以在乾塢有限空間內生產製造,完工後,依據正常程序乾塢進水,塢門打開,整體浮台以直立方式,浮起並拖帶出乾塢,在港內或其他平靜水域再以適當方法,由直立姿態,翻正為水平姿態,正常地浮於海面。這樣一來,本發明一種海洋浮台的直立式製造方法可在乾塢內經濟生產,不需要另外投資建造更大型的乾塢或滑台來生產,不會增加建造海洋浮台的成本。 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.
