Building process of upper assembly of maritime booster station

Abstract

The invention discloses a building process of an upper assembly of a maritime booster station. The building process comprises the following steps that (1) all layers of deck pieces are prefabricated and hoisted; (2) preparation is conducted before the deck pieces are hoisted; (3) the bottom deck pieces and related devices are hoisted; (4) the second layer of deck pieces and related devices are hoisted; (5) the third layer of deck pieces and related devices are hoisted; (6) the fourth layer of deck pieces are hoisted; and (7) the fifth layer of deck pieces are hoisted. When the upper assembly is built, all layers of deck pieces and segments of a steel structure building are hoisted from bottom to top and from inside to outside, land construction of the upper assembly adopts the method of segment prefabrication and integral hoisting, the land prefabrication depth is increased as much as possible, and the aerial working amount is reduced; and meanwhile, the related devices on the deck pieces are installed in place after the deck pieces are hoisted, the maritime tooling quantity is reduced, trouble caused by transportation is also omitted, the steps of the whole building process of the upper assembly are orderly, and the building efficiency and precision are greatly improved.

Description

technical field [0001] The invention belongs to the field of marine transportation and manufacturing, and in particular relates to a construction process for an upper component of an offshore booster station. Background technique [0002] With the huge consumption of fossil energy and the serious pollution of the environment, renewable energy has received more and more attention from all over the world, and wind energy has become one of the most competitive new energy sources. Compared with onshore wind power, offshore wind power is not only inferior Occupying land resources, rich in energy, stable output, and high utilization rate have become a new direction for the development of wind power in the world. At present, most of the offshore wind power under construction in my country is 10-30km offshore, and the planned capacity of the project is 200-300kw. Multiple 3mw-6mw offshore wind turbines are used to generate power in groups, and the power is sent to the offshore step-...

AI Technical Summary

Problems solved by technology

[0003] The traditional offshore step-up station has the following disadvantages in the construction of superstructures: the structure of the superstructure is relatively complex, and there is no sequence in the process of constructing the superstructure. Due to the large number of superstructure structures, it is easy to miss small structures such as columns in the process of prefabricating decks, which greatly reduces the The stability of the offshore step-up station is reduced. During the welding process, any direction can be welded at will. Since many people are welding, the symmetrical distribution of welding cannot be guaranteed, and welding deformation is prone to occur. The entire welding closing process has low precision and poor efficiency.
