The invention discloses an undocking method suitable for a cylindrical FPSO (floating production storage and offloading), which comprises the following steps: S1, mooring and marking in a dock, and arranging a scheme according to a towing cable and rigging of the cylindrical FPSO in the dock; s2, balance weight load adjustment; s3, floating and leveling; s4, guiding the ship in the dock; s5, the dock gate is moored; s6, driving a main tug; s7, guiding the ship out of the dock; and S8, guiding the ship in the harbor basin. According to the undocking method suitable for the cylindrical FPSO, the cylindrical FPSO is guided to be undocked, so that the problems that a cylindrical structure is difficult to balance and adjust and easy to rotate in the undocking process are solved, and the difficulty that the distance between a bottom zigzag damping plate and a dock wall is difficult to observe underwater is effectively overcome; compared with the prior art, the safety of the cylindrical FPSO undocking process is remarkably enhanced, meanwhile, the working efficiency is greatly improved, and therefore safe and efficient undocking of the cylindrical FPSO is achieved, and the overall quality of undocking operation is improved.

    本发明公开了一种适用于圆筒型FPSO的出坞方法,该适用于圆筒型FPSO的出坞方法包括以下几个步骤:S1、坞内带缆及标记,根据圆筒型FPSO在船坞内的拖曳缆绳索具布置方案;S2、配重调载;S3、起浮调平;S4、坞内引船;S5、坞门启泊;S6、带主拖轮;S7、引船出坞;S8、港池引船。本发明提供的适用于圆筒型FPSO的出坞方法,通过引导圆筒型FPSO出坞,不仅解决了圆筒型结构在出坞过程中难以平衡调整且易于转动的问题,还有效克服了底部锯齿形阻尼板在水下与坞墙难以观察间距的困难,圆筒型FPSO出坞过程的安全性得到了显著增强,同时工作效率也得到了大幅提升,从而实现了圆筒型FPSO能够安全、高效地出坞,提升了出坞操作的整体质量。
