Floating drilling platform for offshore oil / gas drilling and exploration in ice-infested polar areas

A floating drilling platform for offshore oil/gas drilling and exploration in ice-infested polar areas, comprising a deck module, a first compartment and a second compartment sequentially connected from top to bottom;

• wherein
• a bottom of the deck module is connected to a top of the first compartment by evenly distributed columns;
• both the first compartment and the second compartment are cylinders centrally arranged with center wells;
• the deck module is also centrally arranged with a center well;
• the first compartment, the second compartment and the deck module are coincident with a centerline;
• an outer diameter of the second compartment is larger than an outer diameter of the first compartment;
• an outer diameter of the deck module is larger than an outer diameter of the first compartment;
• a top of the first compartment is designed with a circular inclined plane upwardly and outwardly arranged at an outer edge;
• a top of the circular inclined plane is connected to the bottom of the deck module;
• the second compartment is internally arranged with a plurality of ballast compartments;
• and
• the first compartment is internally arranged with a plurality of void compartments;
• and
• wherein a cross section of the center well of the deck module, a cross section of the center well of the first compartment and a cross section of the center well of the second compartment are of square type, and wherein four corners of the center well of the first compartment are internally arranged with vertical staircase shafts, bottom of the vertical staircase shafts is closed to avoid contact with seawater, and the vertical staircase shafts are communicated with void compartments within the first compartment.
