The invention discloses a method for undocking a triangular large floating steel structure, which belongs to the technical field of ocean engineering, and comprises the following steps: arranging a winch group on a dock, and then connecting the winch group with one end of the floating steel structure back to a dock gate through a cable on the winch group; seawater is injected into the dock, so that the floating steel structure naturally floats; the first tug and the second tug enter the dock, and the two ends, facing the dock gate, of the floating steel structure are connected with the first tug and the second tug through mooring ropes correspondingly; after the floating steel structure moves out of the dock gate, the first tug and the second tug stop towing operation, and then the third tug is connected with the end, opposite to the dock gate, of the floating steel structure through a cable; the first tug, the second tug and the third tug drag the floating steel structure away from the dock. According to the invention, the triangular large floating steel structure can be towed to completely leave the dock through the three tugs, so that the direction of the floating steel structure in water is always controlled.

    本发明公开了一种三角形大型浮式钢结构物的出坞方法,属于海洋工程技术领域,包括以下步骤:在船坞上布置绞盘组,随后通过绞盘组上的缆绳与浮式钢结构物背向坞门的一端连接;向船坞内注入海水,使浮式钢结构物自然浮起;第一拖轮和第二拖轮进入船坞内,将浮式钢结构物朝向坞门的两个端部通过缆绳分别与第一拖轮以及第二拖轮连接;在浮式钢结构物移动坞门外后,第一拖轮和第二拖轮停止拖带作业,随后第三拖轮通过缆绳与浮式钢结构物背向坞门的一端连接;第一拖轮、第二拖轮以及第三拖轮拖带浮式钢结构物远离船坞。本发明通过三条拖轮即可拖带三角形大型浮式钢结构物完全驶离船坞,使得浮式钢结构物在水中方位始终控制的效果。
