DRILLING SHIP FOR POLAR REGION

摘要

The present invention relates to a drilling ship that can operate in a polar region, the drilling ship for a polar region characterized by a side shell plate supporting a weather tight structure protecting a drill floor from outside air, with a drilling operation area in the center. The present invention enables easy and economical manufacturing of the weather tight structure, which minimizes the effect of outside air on the drilling operation in a polar region, minimizes structures obstructing the drilling operation area by efficiently supporting the longitudinal strength of a hull and the weather tight structure using only the structure of the side shell plate, eliminates the need to additionally install a structure stiffener to the drilling operation space in a polar region, effectively secures drilling operation space in a polar region, and resolves the issue of space limitation in the upper area of a moon pool.
