The invention discloses a semi-submersible production platform towing and limiting mode conversion method, and relates to the technical field of offshore oil engineering. The method comprises the following operation steps that a platform towing rigging and a limiting rigging are installed on a platform; towing the semi-submersible production platform to an oil and gas field site by three tugs; the towing tug 1, the towing tug 2 and the towing tug 3 are driven to preset positions in sequence, transmission and connection of platform limiting rigging are conducted, and the towing tug 1, the towing tug 2 and the towing tug 3 are all converted into limiting tugs; limiting testing is carried out on the semi-submersible platform through the four limiting tugs, and tie-back of a follow-up mooring system can be carried out when the testing meets the requirement. According to the method, the semi-submersible production platform can be converted into the limiting mode from the towing mode in a seamless connection mode, it is guaranteed that follow-up tie-back and installation work of the semi-submersible production platform is smoothly carried out, and meanwhile the operation time of conversion of the towing mode and the limiting mode of the semi-submersible production platform can be greatly saved.
本发明公开了半潜式生产平台拖航与限位模式转换方法,涉及海洋石油工程技术领域。其操作步骤如下:在平台上安装平台拖航索具与限位索具;将半潜式生产平台由三条拖轮拖航至油气田现场;依次将拖航拖轮1、拖航拖轮2和拖航拖轮3行驶到预定位置,并进行平台限位索具的传递与连接,将拖航拖轮1、拖航拖轮2和拖航拖轮3均转换成为限位拖轮;通过4条限位拖轮对半潜平台进行限位测试,测试满足要求,即可进行后续系泊系统的回接。本发明可使得半潜式生产平台由拖航模式无缝衔接转换为限位模式,保障了半潜式生产平台后续回接和安装作业的顺利开展,同时该发明方法能够较大的节省半潜式生产平台拖航与限位模式转换的操作时间。
