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
Crashing the jacket can cause through cracks at the joints of the tie rods of the jacket legs, so it needs to be repaired. However, the diameter of the jacket legs is small and the internal space is small. If a scaffold is built in the jacket for welding personnel to enter and exit the legs Welding operation is time-consuming, and the safety is not high. The internal working space is even narrower, and only one person can work. The working time is long, which is not good for the project schedule

Embodiment Construction
[0021] 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.
[0022] Figure 1 to Figure 3 It shows a repair platform for the interior of the jacket leg of the present invention, which allows operators to quickly enter and exit the interior of the jacket leg 150 and the structure for safe and effective work inside the leg. It consists of an upper platform 110 , a connecting piece 140 , a working platform 120 and a movable ladder 130 . The upper platform 110 overlaps with the top of the jacket and can be fixed by spot welding. The upper platform 110 and the working platform 120 are fixed through the connecting piece 140 , and personnel enter and exit the jacket leg 150 through the movable ladder 130 . Through the internal repair platform structure of the jacket, the internal spac...

The invention discloses a repair method for an internal of a guide pipe frame pile leg. The repair platform comprises an upper platform, an operation platform and a mobile ladder. The upper platform is built at the top of the guide pipe frame pile leg; and the operation platform is arranged below the upper platform, and extends into the guide pipe frame pile leg. The mobile ladder is operably arranged between the upper platform and the operation platform to realize the access of the internal of the guide pipe frame pile leg. The repair method for the internal of the guide pipe frame pile leg is simple in structure, convenient for use and light in weight, can be wholly prefabricated on land, and is once installed in place on the sea, so that the repair operation of the internal of the guide pipe frame pile leg becomes economical, efficient and safe.
Description
technical field [0001] The invention relates to the field of offshore platforms, in particular to a repair platform for the inside of jacket legs. Background technique [0002] In the past ten years, more and more offshore platforms have been installed offshore. Offshore platform installation is a high-risk operation, and there are occasional installation failures, which will inevitably cause damage to the jacket. Crashing the jacket can cause through cracks at the joints of the tie rods of the jacket legs, so it needs to be repaired. However, the diameter of the jacket legs is small and the internal space is small. If a scaffold is built in the jacket for welding personnel to enter and exit the legs Welding operation is time-consuming, and the safety is not high, and the internal working space is even narrower. Only one person can work, and the working time is long, which is not good for the project schedule. Contents of the invention [0003] The technical problem to b...
