Abstract
The invention relates to a multi-order semi-submersible platform which comprises an upper platform body and a lower floating body. The lower floating body comprises an annular float, transverse floats and longitudinal floats which are connected with each other in a crossed mode are arranged in the annular float. The inner sides of the upper platform body extend to the center of a circle so that second berth platforms can be formed. Multiple uprights arranged along the circumference at intervals are connected between the upper platform body and the lower floating body. Boss portions extending outwards are symmetrically arranged on the outer circumference of the upper platform body. First berth platforms are arranged on the boss portions on the upper platform body. According to the multi-order semi-submersible platform, a seawater suction system arranged on the lower floating body is used for effectively ballasting the lower floating body with seawater and discharging the seawater; when a severe sea condition occurs, the draught is increased, the dead weight of the platform is increased, so that the height of the portion exposed out of the sea level is greatly reduced, and the wind resistant capacity in the severe sea condition is greatly improved; the transverse floats and the longitudinal floats are combined and crossed, so that a crossed structure is formed, the crossed structure is connected with the annular float, the lower floating body is formed, and the effective load capacity of the upper platform body is guaranteed.
