[0002] An offshore platform is a truss structure that is higher than the sea level and has a horizontal surface. It is used for production operations or other activities. When constructing an offshore platform, since corresponding power devices, mud circulation purification equipment, etc. need to be placed on the offshore platform, in order to ensure sufficient space on the offshore platform, it is usually necessary to expand the capacity to increase the floor area. When expanding the capacity of an offshore platform, it is usually necessary to use a conductor frame as a steel frame for support operations.

[0003] When using the jacket for support operations, in order to ensure that the structure between the jacket and the base of the offshore platform is more solid and stable, it is usually necessary to use a pulling structure to perform a pulling and limiting operation. However, the traditional pulling structure is fixed in a single way, and the number of its fixing points is small, which will cause the overall structure to be unstable, affect the use effect, and bring inconvenience to the user. In view of this, we propose a jacket pulling structure for offshore platform expansion. Utility Model Content
