Self-adaptive stepless regulation ladder stand facility for offshore booster station under thick sludge condition

Abstract

The invention discloses a self-adaptive stepless regulation ladder stand facility for an offshore booster station under a thick sludge condition. The defects of a ladder stand for the offshore booster station in the prior art are overcome. Ladder beams and step structures of the ladder stand adopt a double-locknut and bolt connection process, so that the structure is safe and reliable, and meanwhile, a self-adaptive stepless regulation mechanism for on-site installation of the ladder stand is realized. The self-adaptive stepless regulation ladder stand facility is arranged between an upper structure main beam and a lower jacket inner platform and comprises a pair of ladder beams arranged in parallel and a plurality of steps, one ends of the ladder beams are rotationally connected with the upper structure main beam, the other ends of the ladder beams are connected with the lower jacket inner platform, the steps are erected between the pair of ladder beams, and the two ends of the steps are correspondingly and rotationally connected with the ladder beams on one side.

Description

technical field [0001] The invention relates to an adaptive stepless adjustment ladder facility of an offshore booster station under thick silt conditions, which is suitable for the field of offshore wind power generation. Background technique [0002] Nowadays, the wind power industry is in a high-explosive development trend. The scope of wind power development in land areas and even offshore areas is gradually decreasing, and its development is gradually restricted. People turn their attention to deep sea areas. This area has many advantages such as less interference factors, stable wind force and fast wind speed, and it will be the development trend of the wind power industry in the future. As the hub of offshore wind power transmission, the offshore booster station plays an important role in the operation of the entire offshore wind farm. [0003] The ladder of the offshore booster station is the main channel connecting the upper and lower structures and the transportat...

AI Technical Summary

Problems solved by technology

However, because the water depth in the deep sea area is often relatively large, and the seabed surface is often accompanied by a thick silt covering layer, it is inevitable that a certain degree of subsidence will occur in the offshore booster station, which brings difficulties for the connection and installation of its upper and lower structures. extremely adverse effect

Under this condition, if the traditional fixed ladder is used to connect the upper and lower structures, the welding installation must be completed after the upper and lower parts are connected. At the same time, it is necessary to be equipped with a crane to assist the positioning of the ladder, which is very time-consuming and laborious.

Moreover, due to the suspension of the construction site, it brings great obstacles to the installation and positioning of the structure, especially for some booster station structures with limited reserved installation space, the installation and positioning work will be more difficult

In addition, considering the impact of the subsidence of the booster station structure, the traditional ladder needs to reserve a long enough cutting margin to ensure the connection between the upper and lower parts, which increases the difficulty of on-site support tooling and transportation.

Therefore, the traditional ladder structure has many disadvantages such as high installation cost, difficult construction, waste of materials, long operating hours, etc., which has a very adverse impact on the construction of offshore booster stations.
