The supporting body 45 is convenient for arranging the supporting seat 43 and the lifting device, and the driving part 44 directly drives the supporting body 45 to realize that the supporting seat 43 moves along the width direction of the notch 1 a.

In this embodiment, the barge is provided with a notch 1a, the second maritime module 2 is positioned in the notch 1a, and the second maritime module 2 can be pre-fixed at a predetermined maritime position, and the position of the barge can be adjusted so that the second maritime module 2 is positioned in the notch 1a of the barge. In particular in fig. 2 and 3, the second marine module 2 is a jacket. And the supporting parts are arranged on the barge corresponding to the two sides of the notch 1a and comprise supporting seats 43 and lifting devices, so that when the first marine module 3 is installed, the first marine module 3 can be pushed or pulled from the barge to the supporting parts, the first marine module 3 is supported by the supporting parts, then the barge can be ballasted to increase the draught depth, the height of the first marine module 3 is reduced, and then the height of the supporting seats 43 is further adjusted by the lifting devices, so that the height of the first marine module 3 is continuously adjusted until the butt joint installation with the second marine module 2 is completed. It can be seen that by providing the lifting means, the first marine module 3 can be height adjusted and the ballast system requirements for the hull 1 are reduced.

Further, in the present embodiment, the inner and outer ends of the supporting body 45 are respectively provided with the supporting portion and the weight portion. As shown in FIG. 2, taking the first side slot portion on the right side of the barge as an example, the support portion is located at the left end, i.e., the inner end, of the first side slot portion, and the counterweight portion is located at the right end, i.e., the outer end, of the first side slot portion. Since the support portion is used for supporting the first marine module 3, the position of the support portion can bear a large load, the load of other positions of the support main body 45 is small, and the counterweight portion is arranged at the other end opposite to the support portion, which is beneficial to improving the stability of the support main body 45 and reducing the strength requirement of connection with a barge.

As shown in fig. 2, the counterweight may specifically include ballast tanks 41, the ballast tanks 41 being capable of communicating with the barge's ballast system. It will be appreciated that the barge, for smooth transport, will be provided with ballast systems that can adjust the draft of the hull 1 by injecting water to adjust the weight of the barge at various locations, as previously described. In this embodiment, the ballast tank 41 is connected to the ballast system of the barge, so that the existing ballast system of the barge can be used to supply water to the ballast tank 41, thereby achieving the purpose of weighting. As shown in fig. 1, two sets of supporting bodies 45 are disposed at the end of the barge, and two sets of supporting seats 43 are correspondingly provided, so that when the first marine module 3 is supported by one set of supporting seats 43, water can be filled into the ballast tank 41, and when the first marine module 3 is completely supported by two sets of supporting seats 43, the ballast tank 41 can be filled with the required amount of water, so that the counterweight of the ballast tank 41 is gradually completed, and the stress of the supporting bodies 45 is stable in the whole supporting process. After the first marine module 3 is installed, the ballast tank 41 may be drained through a line with the ballast system, or may be vented separately by providing a valve.

As shown in fig. 2, the weight section and the support section both extend at least partially out of the barge. The extension of the support to the inboard side of the barge ensures that it is in supporting contact with the bottom of the first maritime module 3, while the extension of the counterweight to the outboard side of the barge reduces the volume occupation of the barge and facilitates the arrangement of other components.

As shown in fig. 1-3, the support body 45 also includes a securing structure 42 for securing the support to the barge. Although a counterweight is provided for balancing the stress of the support portion, in order to ensure that the support portion supports the first marine module 3 more reliably, it is preferable to fix the support portion by the fixing structure 42, specifically, to fix the support main body 45. The specific form of the fixing structure 42 is various, such as fastening by bolts, clamps, pins, etc., and this scheme is not limited specifically.
