Offshore platform transport device

Abstract

The invention belongs to the field of oceanographic engineering and particularly relates to an ocean platform transportation device and a transportation method for transporting a large ocean platform. The ocean platform transportation device comprises a body, a fixed winch, a traction winch, a base, sliding rails and sliding shoes. The ocean platform transportation device is of an axisymmetric structure and is symmetric relative to the longitudinal axis, a prismatic ballast compartment is arranged inside the body, the outer side of the body is provided with the traction winch and the fixed winch in the longitudinal direction, and a sliding way is arranged at the top of the body. An elastic sliding block is installed in the sliding way and can slide in the sliding way, the top of the elastic sliding block is fixed with the bottoms of the bases, and the position of the elastic sliding block in the sliding way is adjusted through a rocking box. The sliding rails are laid on all of bases, the bottoms of the sliding shoes are sliding rail grooves, and the sliding shoes are connected with the sliding rails through the sliding rail grooves. The transportation device can perform complete submersible operation within certain depth, achieve autonomous separation of the large ocean platform in the submersing process, shorten a shipment period and reduce the construction cost and performs towage in a semi-submersible mode, and water surface stormy wave influence on the device is small.

Description

technical field [0001] The invention belongs to the field of ocean engineering, and in particular relates to an ocean platform transport device and a transport method, which are used for transporting large ocean platforms. Background technique [0002] The continuous development of offshore engineering and the increasing depth of operation have made offshore platform structures such as platform jackets and modules more and more large. The traditional lifting and transportation methods are not suitable for the transportation of such structures. At this stage, the mainstream transportation method is to use The skid method is used to load and launch large offshore platforms. During the launching process, the large-scale offshore platform can turn over from the beginning to the complete water-entry, and the turning angle can reach 30°. During the movement, the overall center of gravity of the large-scale offshore platform and barge is constantly moving, which requires real-time ...

AI Technical Summary

Problems solved by technology

At present, the movement speed, trajectory, and water depth margin of large-scale ocean platforms in the entire launching process are controlled by on-site experience and manual measurement. There are many unstable factors and hidden safety hazards, which will bring great disaster if you are not careful; and large-scale Offshore platforms have very strict requirements on the capacity of transport barges, which require large volumes and a certain depth, and require very high longitudinal strength of barges. The cost of hiring such barges is very expensive
