The unloading of equipment and materials of transport ships under non-dock conditions is generally achieved by overhauling or constructing a temporary barge platform, and the transport ships are usually connected to the barge platform in a “side-berthing mode” or a “top-berthing mode”. Due to the long distance from the shore, the ships are greatly affected by the sea waves, and the side-berthing or top-berthing operation between the ships is difficult, inefficient, and has poor stability and reliability. The technology of connecting and loading / unloading equipment and materials between ships in an open sea area in a side-berthing and top-berthing mode is not mature at present.
