FPSO直升飞机平台吊装工艺
摘要：
本发明公开了FPSO直升飞机平台吊装工艺，包括S1：地面上给FPSO直升机平台安装六个吊耳；S2：安装主吊绳组和辅助吊绳组，主吊绳组连接第一、第二吊耳、辅助吊绳组连接第五、第六吊耳；S3：吊装所述FPSO直升机平台至空中，并脱钩第五、第六吊耳，将直升机平台旋转180°后，更换成辅助吊绳组连接第三、第四吊耳，从而完成直升机平台的空中翻身；S4：将所述FPSO直升机平台吊装上FPSO船体甲板，并利用限位装置固定直升机平台。本发明的吊装工艺，吊耳均衡地设置在远离直升机平台重心线的两个相反方向，避免在直升机平台翻身过程中，出现一辅助吊绳组呈瞬间失力而主吊绳组承受瞬间冲击力的状况，保证了起吊过程的安全。
摘要（英）：

The invention discloses an FPSO helicopter platform hoisting process. The process comprises the steps that firstly, six hoisting lugs are mounted on an FPSO helicopter platform on the ground; secondly, a main hoisting rope set and an auxiliary hoisting rope set are mounted, the main hoisting rope set is connected with the first hoisting lug and the second hoisting lug, and the auxiliary hoisting rope set is connected with the fifth hoisting lug and the sixth hoisting lug; thirdly, the FPSO helicopter platform is hoisted to the air, the fifth hoisting lug and the sixth hoisting lug are unhooked, and after the helicopter platform is rotated by 180 degrees, the auxiliary hoisting rope set is connected with the third hoisting lug and the fourth hoisting lug in a replaced mode, so that air turning of the helicopter platform is completed; and fourthly, the FPSO helicopter platform is hoisted onto an FPSO ship body deck, and the helicopter platform is fixed through a limiting device. According to the hoisting process, the hoisting lugs are evenly arranged in the two opposite directions away from the gravity center line of the helicopter platform, the situation that one auxiliary hoisting rope set loses force instantly and a main hoisting rope set bears impact force instantly during turning of the helicopter platform is avoided, and the safety during hoisting is ensured.
