The invention discloses an anchor mooring structure of a semi-submersible drilling auxiliary platform, and relates to the technical field of ocean engineering, each group of anchor gears is provided with a steel wire rope and two groups of anchors, guide wheels are arranged on the anchor gears, and the anchor gears at four corners of a deck pack position a drilling platform at an offshore operation position through the anchors; four sets of stand columns are arranged below the deck bag, floating boxes are arranged below the stand columns, the stand columns are distributed corresponding to the positions of the pipe frame decks, floating box decks are arranged on the surfaces of the floating boxes, the floating box decks are connected with the deck bag through the stand columns, and anchor frames are arranged at the positions, corresponding to the anchor gears, of the floating boxes. According to the anchor mooring structure of the semi-submersible type drilling auxiliary platform, eight anchors of the four sets of anchor machines form an eight-point mooring system, the steel wire ropes and the anchors are connected and put, good stability can be provided for the drilling platform, the number of the anchors of the anchor machines is reduced, the structure is optimized, construction and building are convenient, and the follow-up operation and maintenance cost of the platform is reduced; the service life and economic benefits of the drilling platform are improved.
本发明公开了半潜式钻井辅助平台锚系泊结构,涉及海洋工程技术领域,每组锚机设置有钢丝绳和两组锚,锚机上设置有导向轮,甲板包四个角落的锚机通过锚把钻井平台定位在海上运营位置;甲板包下方设置有四组立柱,立柱下方设置有浮箱,立柱对应管架甲板的位置分布,浮箱表面设置有浮箱甲板,浮箱甲板和甲板包之间通过立柱连接,浮箱对应锚机的位置设置有锚架。根据本发明的半潜式钻井辅助平台锚系泊结构,四组锚机共八根锚组成8点系泊系统,钢丝绳和锚连接投放,能够为钻井平台提供良好的稳定性,简化了锚机的锚数量,优化结构,方便施工建造,降低平台后续运营维护成本,提升钻井平台使用寿命和经济效益。
