Abstract
A floating drilling platform for offshore oil/gas drilling and exploration in ice-infested polar areas comprises a deck module, a hard compartment, and a soft compartment sequentially connected from top to bottom. The bottom of the deck module is connected to the top of the hard compartment by evenly distributed column. Both the hard and the soft compartments are cylinders centrally arranged with center wells. The deck module is also centrally arranged with a center well. The hard compartment, the soft compartment and the deck module are coincident with a centerline. The outer diameter of the soft compartment, as well as that of the deck module, is larger than that of the hard compartment. The top of the hard compartment is designed with a circular inclined plane upwardly and outwardly arranged at the outer edge. The top of the circular inclined plane is connected to the bottom of the deck module.
