[0002] When using a crane on a ship or floating platform for lifting, the cargo will sway due to the six-degree-of-freedom motion of the ship under the action of waves, affecting normal operations. Usually, lifting operations can only be carried out in sea conditions below level 3. Even when operating in sea conditions below level 3, there is still the problem of cargo swaying. The existing technology uses a compensating crane, but this system contains multiple components and a complex system structure with high cost, and its system implementation is also relatively complex.

[0003] In the prior art, there is a technology named "Lifting Technology for Heavy Lifting of Engineering Ship Platform" with a publication (announcement) number of "CN112938764A". This technology discloses a lifting technology for heavy lifting of engineering ship platform, which includes the following steps: (1) analyzing the basic lifting conditions; (2) rationally arranging the lifting points; (3) calculating the impact force of the heavy lifting of the platform on the base during the lifting process; (4) welding and non-destructive testing analysis of the heavy lifting platform and the base; (5) dynamic simulation of the lifting process; and (6) actual lifting. The present invention can carefully consider the entire platform heavy lifting installation process, including from the platform leaving the mooring test dock to the lifting area until the installation is completed, which not only ensures the one-time success of the heavy lifting installation of the platform, but also ensures the economy and safety of the installation.

[0004] In the prior art, there is a technology named "A platform-based lifting device and its vessel" and with a publication (announcement) number of "CN115783973A", which provides a platform-based lifting device and its vessel. The platform-based lifting device includes a support platform and a tooling piece; a notch is provided on the support platform, and the notch passes through the first end face and the second end face of the support platform, and a plurality of positioning columns are provided on the first end face; a plurality of mounting holes are provided on the tooling piece, and the tooling piece is placed on the first end face, and the mounting holes are sleeved on the positioning columns, and the tooling piece has a lifting portion, and the lifting portion extends from the notch and is used for lifting. The notch in the support platform allows the tooling piece to suspend heavy objects, and the tooling piece itself has good strength, which helps to solve the technical problem in the prior art of lacking a lifting device that can suspend heavy objects and has good strength.

[0005] However, this technology does not involve the technical problems and technical solutions of the present application. Utility Model Content
