Description

Anti-theft structure of jacket boarding system

Technical Field

The utility model relates to the technical field of safety protection, in particular to an anti-theft structure of a jacket boarding system.

Background

The ocean resources are inexhaustible. In recent years, the development and exploration of marine resources for human beings have been increasing, and particularly in offshore sea areas, human activities have been more and more frequent. Marine platforms based on jackets are increasingly used in the development of marine engineering. Because the current ocean development project is still mainly in the offshore sea area, the maritime work platform often encounters a lot of 'untimely guests' in the actual operation process, the equipment and materials on the platform often disappear in a famous and wonderful manner, and especially the loss of some key equipment may cause great loss to the production operation of the whole project, so the anti-theft problem of the maritime work platform is more and more concerned by the industry.

The boarding system on the jacket is a necessary path for entering the upper structure of the maritime work platform, so engineering designers often set an anti-theft structure at the boarding system of the jacket. Currently, there are two mainstream design schemes in the industry: (1) completely closing the boarding passage of the jacket boarding system by using a cabin wall plate or a steel pipe; (2) a fully enclosed stairwell is provided at the entrance to the upper landing. The former has hoisting risk after integral installation, so the installation is often needed after the hoisting, the field welding workload is large, and the scheme is expensive in manufacturing cost due to large windward area on the marine platform, large wind load and high requirements on structural strength and rigidity; the latter takes up a portion of the valuable space of the upper platform and also adversely affects the safe evacuation of the platform personnel.
