Column stabilized platform with improved heave motion

摘要

The semi-submersible platform comprises a submersible lower hull including a plurality of spaced-apart hull segments. A wave- transparent stabilizing superstructure extends from the lower hull. An upper hull is supported by the superstructure. A wellhead system is suspended from the platform. A catenary mooring system moors the platform to the seabed, and plurality of risers connect the individual wellheads on the platform to the wellbores in the seabed.
