Abstract

Technical Field
[0001] The utility model relates to a transport fixing device, in particular to a fixing device used for transporting a slender and tall upper module SPMT of an FPSO. Background Art
[0002] The transportation and installation technology of the slender upper modules of floating liquefied natural gas facilities (FPSOs), as the core components of FPSOs, is a hot topic in the industry. At present, the commonly used method of transporting slender upper modules of FPSOs is to transport them by SPMT (self-propelled module transporter) and tie them up with ropes. However, due to the special slender structure of the FPSO upper modules, as well as the large and uneven distribution of mass, the modules are more likely to move during the transportation of the modules due to speed changes, rugged roads, etc. The traditional bundling and fixing greatly limits the transportation speed of SPMT (self-propelled module transporter), which not only leads to poor transportation efficiency, but also poor stability of the modules during transportation, and safety cannot be guaranteed.

[0006] The advantages of the utility model are as follows: it can be applied to various structural types of FPSO slender and tall upper modules and structural characteristics of large mass and uneven distribution. It adopts multiple hydraulic cylinders and V-shaped clamping structure for fixing, thereby improving the stability of the module during transportation. The fixed baffle and the clamping device are fixed with bolts and threaded holes of different heights are reserved, so the clamping device can be easily disassembled and replaced, meeting the requirements of different clamping heights and the number of clamping devices, thereby greatly improving the transportation efficiency.
