Problems solved by technology

At the same time, the spud shoes need to use the buoyancy of the platform itself in the process of pulling out piles, and use the pile pulling capacity of the lifting device to pull out the spud shoes, which consumes a lot of power and can only be operated with single piles in sequence, which is risky

Abstract

The invention relates to a suction type spud shoe and an installation method suitable for a self-elevating platform. The suction type spud shoe includes a top cover plate, a main rib plate, a reinforcement rib plate, an upper transverse plate, an upper peripheral plate, a lower bearing plate, and a skirt plate main rib Plate, skirt plate stiffener plate, lower transverse plate, lower peripheral skirt plate and injection and drainage pipes, by setting the skirt plate at the bottom of the spud can of the flying saucer-shaped structure, a suction structure of the tube foundation is formed, and the suction pile foundation installation technology and its It simplifies the installation of spud cans, effectively increases the bearing capacity of spud cans, and has a certain anti-slide pile ability in shallow soil layers. At the same time, it provides a certain upward jacking force by filling the cavity of the pile foundation below. Effectively reduce the difficulty of pile extraction.

Description

technical field [0001] The invention relates to a self-elevating platform spud can and its installation method, especially the suction spud can and its installation method of the self-elevating platform used in marginal oil field development and short-term migration. Background technique [0002] The offshore jack-up platform is the most commonly used production equipment in the offshore oil industry. Its advantage is that it can be lifted and lowered by itself, and it is almost not restricted by terrain and other conditions. The installation period is short and the production is fast. According to the requirements of different oil and gas field development, different production and living facilities can be configured, and the equipment utilization efficiency is high. It has great adaptability and is an essential part of the offshore oil production system. [0003] Flying saucer-shaped spud cans are generally used on offshore jack-up platforms. The main structure includes t...
