Problems solved by technology

Due to the height, outer diameter and weight of the FPSO crane itself, the processing and construction of the FPSO crane body, as well as the hoisting and installation plan, are the difficulties and key factors of the entire crane project. It must not only meet the structural design requirements, but also It meets the requirements of structural strength and resistance to large-scale wind at sea. In addition, since the outer diameter of FPSO is 3.7m, the installation of the entire gram crane on the FPSO will take up a lot of hull space

Embodiment 1

[0050] Such as Figure 1~2 , the FPSO gram suspension cylinder body, including the upper cylinder body 1 and the lower cylinder body 2 connected in sequence: the upper cylinder body 1 is formed by sequentially connecting the A part 11 and the B part 12, and the A part 11 is formed by the first cylinder body 111 and the first cylinder body 111 The first frustum-shaped cylinder 112 is connected up and down, and the B part 12 is cylindrical, which is the second cylinder; the lower cylinder body 2 includes an inboard part 21 and an outboard part 22, and the inboard part 21 includes an up and down connection in turn. The first semi-cylindrical body 211, the first semi-circular truncated cylindrical body 212 and the second semi-cylindrical body 213, the outboard part 22 includes the third cylindrical body 221, the third semi-cylindrical body 222 and the first semi-conical body connected up and down in sequence. shaped cylinder 223, the upper cylinder body 1 is connected with the out...

Embodiment 2

[0053] The construction and installation method of the FPSO crane body of embodiment 1 are as follows:

[0054] S1: The construction method of the FPSO crane body:

[0055] S11: Manufacture of lower hull inboard part 21, lower hull outboard part 22, upper hull A part 11, upper hull B part 12:

[0056] (1) Steel plate blanking cutting: cutting different steel plate raw materials according to the different shapes of the lower shell inboard part 21, the lower shell outboard part 22, the upper shell A part 11, and the upper shell B part 12;

[0057] (2) Steel plate rolling processing and forming: the inboard part 21 of the lower cylinder body is divided into the first semi-cylindrical body segment, the first semi-circular frustum-shaped cylindrical body segment and the second semi-cylindrical body segment, respectively rolled and processed, and the lower cylinder body The outboard part 22 of the body is divided into the third cylindrical body segment, the third semi-cylindrical b...

Abstract

The invention relates to a float production storage and offloading (FPSO) crane cylinder body and a construction and installation method thereof. The FPSO crane cylinder body comprises an upper cylinder body and a lower cylinder body. The upper cylinder body is formed by connecting a part A with a part B in sequence. The lower cylinder body comprises an inboard part and an outboard part. The upper cylinder body is connected with the outboard part of the lower cylinder body. The inboard part and the outboard part of the lower cylinder body are fixed to the inner side and the outer side of a side shell of an FPSO and the upper side and the lower side of a main deck of the FPSO. The construction method of the FPSO crane cylinder body comprises the steps of manufacturing and splicing welding of the inboard part of the lower cylinder body, manufacturing and splicing welding of the outboard part of the lower cylinder body, manufacturing and splicing welding of the part B of the upper cylinder body, installation of the FPSO crane cylinder body, modification of the main deck and the side shell of the FPSO, installation of the inboard part of the lower cylinder body, lifting and installation of the outboard part of the lower cylinder body, and lifting and positioning installation of the upper cylinder body. The defect that manufacturing of the huge FPSO crane cylinder body is difficult is overcome, and a large amount of space is saved for an FPSO ship body while the structural strength of the FPSO is guaranteed.

Description

technical field [0001] The present invention relates to a crane body and a construction method thereof, in particular to an FPSO crane body and a construction and installation method thereof. Background technique [0002] Cranes, also known as shipboard cranes and marine cranes, are large-scale deck machinery for loading and unloading cargo on board ships. The characteristics of high height and relatively high adaptability to cargo are mainly composed of the boom and boom bracket, the cab tower body, the gram crane body, the reinforcement under the main deck of the gram crane, the operation and maintenance platform of the gram crane, and the gram crane It consists of internal and external passages and electromechanical equipment. Crane is a structure specially designed by FPSO to realize the operation function. The FPSO design requires no docking for maintenance for 25 years, and the requirements for structural yield and fatigue strength are very high. [0003] In the proj...
