Problems solved by technology

However, the main girder form of the commonly used suspenders in my country is generally a box girder structure, with a set of lifting lugs on the left and right. This kind of suspenders is cumbersome to manufacture, poor in stability, and high in cost, and cannot meet the hoisting needs of modules of different sizes on the FPSO. , poor versatility

Embodiment 1

[0038] Single use method of 1200 tons of multifunctional hanging bar:

[0039] Such as Figure 7 As shown, the present invention is mainly used for four lifting lug modules, and the crane can be used with single or double hooks. First, it is necessary to ensure that the upper and lower lifting eyes of the main beam 1 are used in groups, and the grouping method is determined according to the distance L between the module lifting ears and the direction of the module itself.

[0040] For example: the center distance of the lifting lugs L=14300mm, firstly select two pairs of lifting lugs with a distance of 14300mm from the lower lugs of the main beam 1 and connect them with the rigging of the module lifting lugs, and select the corresponding upper lifting lugs according to the lower lifting lug And use rigging to connect with the sea hook head, other distances are similar to this.

Embodiment 2

[0042] Combination of double 1200 tons of multifunctional hanger bars:

[0043] Such as Figure 8 As shown, this method is the most commonly used, that is, two 1200-ton lifting bars are used in combination, and the crane is hoisted with double hooks. It is mainly used for the lifting of modules with 4 or 8 lifting eyes. The lifting ears must be in the same direction. The method of selecting bar lifting eyes is the same as that of single use; if the crane allows, the maximum lifting capacity of this combination of double lifting bars is 2400 tons.

Embodiment 3

[0045] Combination of 1200 tons of multi-function hanging bars and other two hanging bars:

[0046] Such as Picture 9 As shown, this method is relatively special, it is a two-layer hoisting method, the crane generally chooses a single hook head, which is mainly used for hoisting modules with 4 or 8 lifting ears. The method of selecting the lifting ears of the lifting bar is the same as the single use method. This method can lift up to 1,200 tons.

Abstract

The invention relates to a multifunctional hanging bar which is suitable for hanging modules with different sizes and weight no less than 1200 tons (including 1200 tons) on a FPSO ship. The hanging bar comprises a main bream 1, an upper lifting lug vertical plate 2, an upper lifting lug web plate 3, a lower lifting lug imporous vertical plate 4, a lower lifting lug apertured vertical plate 5, strengthening T sectional materials 6, a transverse strengthening rib plate 7, a transverse strengthening annular plate 8, a faceplate 9, a lower lifting lug web plate 10 and a longitudinal strengtheningrib plate 11. The invention is designed according to the distance between every two FPSO module lifting lugs, is in line with the American Petroleum Institute (API) standard, and is a tool specially designed for hanging the upper modules of the FPSO ship. The invention solves the problems of poor universality, low strength during module hanging, nonuniform stress, and the like of other tools, plays the role of protecting the modules, has extremely high practicability, reduces the cost and the complexity of manufacturing working procedures, and saves materials. The invention has considerably high value of popularization in the fields of ship building and oceaneering.

Description

Technical field [0001] The present invention mainly relates to the field of large-scale module hoisting engineering on the upper deck of floating production, storage and unloading equipment (FPSO) ships and other offshore engineering products, and particularly relates to the hoisting and use of modules with a weight of less than 1,200 tons (including 1,200 tons) on FPSO ships Kind of multifunctional hanging bar. Background technique [0002] With the gradual development of my country’s deep-sea oil fields, the international market’s demand for FPSO ships and other offshore products continues to increase; and with the improvement of my country’s offshore lifting capacity, the number, volume, and tonnage of large-scale marine functional modules are also increasing rapidly. The tonnage has changed from nearly a hundred tons to thousands of tons. Furthermore, the functional module itself is extremely valuable, but the overall structural strength is weak. Therefore, during the lifting...
