Problems solved by technology

The traditional way is mainly that the modules are directly fixed together with the column and the deck base. Since the FPSO has been moored at sea for a long time, it is eroded by wind and waves, causing the hull girder to bend and deform, resulting in cracks in the welding of the joint, which affects the service life of the FPSO

Abstract

The invention discloses an FPSO module. The module comprises a deck base and a module body, a plurality of limiting cushion piers are arranged on the deck base; wherein the plurality of limiting cushion piers are arranged in a matrix arrangement mode; a mounting cavity is formed among the plurality of limiting cushion piers; the module body is provided with a plurality of limiting baffles in one-to-one correspondence with the limiting cushion piers, the module body is arranged in the mounting cavity through a connecting assembly, the connecting assembly comprises a lower connecting plate arranged on the deck base and a connecting seat arranged on the lower connecting plate, and the upper top surface of the connecting seat is connected with the module body. The invention further discloses an integrated installation process of the FPSO module. The FPSO module is simple in structure and convenient to install, the integrated installation technological process is convenient to operate, theintegrated installation error and the design cost are effectively reduced, the installation quality is improved, and the service life of the module is prolonged.

Description

technical field [0001] The invention relates to the field of marine engineering construction, in particular to an FPSO module and an integrated installation process. Background technique [0002] FPSO is the mainstream production device for the development of offshore oil and gas fields today. It can perform preliminary processing, storage and export of offshore crude oil and natural gas. It is a comprehensive large-scale offshore oil and gas production base integrating personnel residence and production command system. Processing plant (Floating Production Storage and Offloading, FPSO)". The traditional method is mainly that the modules are directly fixed together with the column and the deck base. Since the FPSO is moored at sea for a long time, it is eroded by wind and waves, causing the hull girder to bend and deform, resulting in cracks in the welding of the joint, which affects the service life of the FPSO. Contents of the invention [0003] The present invention ai...
