Various equipment is installed on the offshore platform for oil exploration and production, and the standardized fuel gas compressor skid on the offshore platform belongs to the category of skid-mounted equipment for offshore oil platforms. The fuel gas compressor skid is a skid-mounted equipment with high added value and high output value, and it is an indispensable equipment in the natural gas gathering and transportation process. Due to the large volume of the fuel gas compressor skid, it is necessary to use a floating crane and a dynamic sliding trolley for transportation and installation.

[0003] In order to make the dynamic sliding trolley more convenient to use, the Chinese patent with the publication number CN213387680U in the prior art discloses a lifting ground tank.
