Problems solved by technology
Offshore platform installation is a high-risk operation, and there are occasional installation failures, which will inevitably cause damage to the jacket
For example, a platform failed to float for the first time, and the jacket was damaged, resulting in penetrating cracks at the joints of the legs of the jacket
Moreover, the pile legs of the jacket are greatly deformed, resulting in through cracks in the underwater nodes of the jacket
Moreover, the space of the jacket transported back to the wharf after all-out rescue is small, and there is not enough space on the jacket to store maintenance equipment during maintenance, and it is inconvenient for personnel to go up and down the jacket. Moreover, the underwater cracks of the jacket are likely to increase. Deformation of jacket legs

Embodiment Construction
[0019] In order to have a clearer understanding of the technical features, purposes and effects of the present invention, the specific implementation manners of the present invention will now be described in detail with reference to the accompanying drawings.
[0020] figure 1 A multifunctional beam used for jacket repair in the present invention is shown, which is mainly composed of trestle platform 12 , walkway beam 11 , equipment platform 13 and piles 2 on both sides. The piles 2 on both sides are directly inserted into the jacket legs 3, and are fixed by welding the ribs. The interior of the piles 2 is hollow, and personnel can enter and exit the jacket legs 3; there is an equipment platform 13 on the upper part of the piles 2 on both sides for storage. maintenance equipment; the aisle beam 11 connects the piles 2 on both sides to realize the two-axis shuttle of the personnel jacket; the aisle beam 11 is equipped with a trestle platform 12, which is used to carry the float...

The present invention discloses a multifunctional beam for jacket repair. The multifunctional beam comprises a beam body which is used for connecting two sides of a jacket and a pair of pitching piles arranged at two ends of a beam body. Each of the pitching piles is correspondingly inserted into a jacket leg. The beam body comprises an aisle beam for rapidly going through two sides of the jacket, a trestle bridge platform for an operator to rapidly going up and down the jacket, and the trestle bridge platform is at the middle part of the aisle beam. According to the technical scheme, the multifunctional beam for jacket repair has the advantages of simple structure and convenience in use, the multifunctional beam can be integrally prefabricated on a land and installed in place in one time on a sea, and thus the repair working of the jacket leg is more cost-effective, safer and more practical.
Description
technical field [0001] The invention relates to the field of offshore platforms, in particular to a multifunctional beam used for jacket repair. Background technique [0002] Currently, more and more offshore platforms are being installed offshore. Offshore platform installation is a high-risk operation, and there are occasional installation failures, which will inevitably cause damage to the jacket. For example, a platform failed to float for the first time, and the jacket was damaged, causing penetrating cracks at the joints of the legs of the jacket. Moreover, the pile legs of the jacket are greatly deformed, resulting in through cracks in the underwater nodes of the jacket. Moreover, the space of the jacket transported back to the wharf after all-out rescue is small, and there is not enough space on the jacket to store maintenance equipment during maintenance, and it is inconvenient for personnel to get on and off the jacket. Moreover, the underwater cracks of the jack...
