Butt joint and closure method for semi-submersible platform ship body and module

The invention discloses a butt joint and closure method for a semi-submersible platform ship body and a module. The method comprises the steps of ship body docking, ship body positioning, load preliminary transfer, butt joint completion, further load transfer, ship body bottom sitting and all load transfer. For the situation exceeding a guide cone capture range, a corresponding emergency pier sitting capture scheme is started. The invention further comprises a guide cone and a guide block structure matching the method, and deformation of the top position of a stand column when the ship body floats in water is eliminated. And therefore, catching is easier during closure, the closure convenience is improved, and the closure process is smoother. 本发明公开了一种半潜平台船体与组块对接合拢方法，包括以下步骤：船体入坞，船体定位，荷载初步转移，完成对接，荷载进一步转移，船体坐底，荷载全部转移的流程，对于超出导向锥捕捉范围的情况，则启动相应的应急坐墩捕捉方案。本发明还包括此方法相配套的导向锥和导向块结构，消除船体在水中漂浮状态下立柱顶部位置产生的变形。使合拢时更容易捕捉，提高了合拢的便利性，合拢过程更顺畅。
