Jacket levelling construction process of offshore booster station

Abstract

The invention discloses a jacket levelling construction process of an offshore booster station. The jacket levelling construction process comprises the steps that two floating cranes and a pile driving boat are matched for construction, one floating crane lifts a jacket in the whole process to ensure that the jacket is flat and close to the design requirements as far as possible, the other pile driving construction boat is utilized to drive all three auxiliary piles to given positions, then a first product pile is constructed, a method of driving one product pile and pulling one auxiliary pileis adopted to drive the piles to the design elevation in turn, a guide wheel is additionally arranged between the jacket and a foundation pile to ensure the verticality of a pile body, after four piles are all driven, and the matching of the two floating cranes is utilized to adjust the jacket to the final state to meet the design requirements. The jacket levelling construction process is reasonable, the method of driving one product pile and pulling one auxiliary pile is adopted to drive the piles to the design elevation in turn, construction is conducted while levelling, and the problem that it is difficult to level the jacket of the offshore booster station by a traditional process is solved.

Description

technical field [0001] The invention relates to the technical field of offshore construction, in particular to a construction technique for leveling a jacket of an offshore booster station. Background technique [0002] The jacket platform, also known as the pile platform, is supported by piles driven into the seabed and can withstand external forces such as wind, waves, and currents. It can be divided into pile group type, pile foundation type (jacket type) and leg type. Column type, the jacket platform is mainly composed of four parts: jacket, pile, jacket cap and deck, which has the advantages of strong adaptability, safety and reliability, simple structure and low cost. [0003] The world's first fixed offshore platform was built in 1887. It was installed on an oil field in California, USA. It was actually a wooden trestle. After World War II, many advanced scientific and technological achievements used in the war were Applied to marine development, since the United Sta...

AI Technical Summary

Problems solved by technology

[0005] The purpose of the present invention is to provide a construction process for leveling the jacket of an offshore step-up station, which adopts the method of driving a product pile and pulling out an auxiliary pile to hit the piles to the design elevation in turn, and level them while constructing. The method is simple and solves the problem. It overcomes the difficult problem that the traditional technology is difficult to level the jacket of the booster station at sea, so as to solve the problems raised in the above-mentioned background technology
