Method for mounting large-size discharging platform

With the gradual development of the world's deep-sea oilfields, the demand for floating production, storage and offloading units (FPSO) and other offshore products in the international market is increasing. It is converted from a tanker. In the supertanker conversion (FPSO) process, adding a new unloading platform to the extension of the bow deck on the ship is always one of the important projects in the conversion of the floating production storage and offloading unit (FPSO). The weight of the general unloading platform is 150-230 tons, in the process of supertanker conversion floating production storage and offloading (FPSO) in the past, the installation of the unloading platform was mainly carried out by large floating cranes. Due to the change of the line type at the head and tail, the installation process required a large range of repairs and adjustment, the sealing cannot be carried out immediately, and the crane can only be allowed to loosen the hook until the sealing is completed. The installation process of the first unloading platform takes 2-3 days, which will greatly increase the use time of the crane, and at the same time work at night, which reduces the The safety of construction and the difficulty of construction quality control have increased. In order to reduce production costs, improve production efficiency and construction safety, a scientific, reasonable and safe installation method design is essential
