The invention discloses a special-shaped flat plate anchor for permanent mooring of offshore floating facilities and an installation method thereof.The special-shaped flat plate anchor comprises a bearing anchor plate, an anchor top plate, an anti-scouring group plate and a mooring lug plate, the top edge of the bearing anchor plate is perpendicularly connected with one side edge of the anchor top plate, and the bearing anchor plate is inserted into a seabed to make extrusion contact with the front face of soil; an anti-scouring group plate extending downwards is arranged on the edge of the other side of the anchor top plate, scouring of soil on the surface layer of a seabed below the anchor top plate is relieved through the anti-scouring group plate, meanwhile, the anti-scouring group plate serves as a reinforcing rib to reinforce the structure of the anchor top plate, and the mooring lug plate is fixed to the bearing anchor plate in the longitudinal direction of the bearing anchor plate. A lug hole for connecting a mooring rope is formed in the lower part of the mooring rope. The method can effectively solve the problems that a mooring anchor is difficult to design, the safety risk is high and the cost is high when a large offshore floating type facility is permanently moored in shallow sea with the water depth within 50 meters.
本发明公开了一种用于海上浮式设施永久系泊的异型平板锚及其安装方法,包括承载锚板、锚顶板、防冲刷群板和系泊耳板,所述承载锚板的顶边与锚顶板的一侧边垂直连接,通过承载锚板插入海床与土壤正面挤压接触,以提供主要的系泊承载力,所述锚顶板的另一侧边缘处设置有向下延伸的防冲刷群板,通过防冲刷群板减缓锚顶板下方海床表层土壤的冲刷,同时作为加强筋对锚顶板的结构进行加强,所述系泊耳板沿承载锚板的纵向固定于承载锚板上,其下部设置有用于连接系泊缆的耳孔。本发明能够有效解决大型海上浮式设施在50米水深以内的浅海进行永久系泊存在系泊锚设计困难、安全风险大、成本高昂的问题。
