Description

Technical Field

[0001] The utility model relates to the technical field of offshore oil engineering, in particular to a jacket steel pile simulation pile combination device. Background Art

[0002] During the construction of deepwater jackets for offshore oil projects, steel pile-type jackets are a more common type of jacket structure. During the offshore installation phase, steel piles are driven into the seabed through the jacket skirt pile structure. Finally, concrete is poured into the enclosed space formed between the pile holders, packers and steel piles in the skirt piles to fully secure the jacket.

[0003] During the onshore construction phase of a jacket, to ensure proper function of the packers within the skirt piles during offshore installation, individual dummy piles of corresponding specifications are typically rolled according to the skirt pile size. Each skirt pile is then tested sequentially to ensure the required sealing performance. Traditionally, a single dummy pile is used to test all skirt piles in sequence. Testing a single skirt pile takes approximately three days, and testing all skirt piles takes nearly a month. This results in a long construction cycle, occupies resources such as cranes, and reduces construction efficiency. Therefore, a jacket steel pile dummy pile assembly device has been developed to address these issues. Utility Model Content
