StudyThe Central Pontoon (CP) Semi is an efficient production facility for the viable development of deep and ultra deep fields. It consists of an octagonal continuous central pontoon structure and four radially oriented columns outboard of the pontoons.  The radial orientation of the columns enhances the stability of the platform during quayside integration of the topsides whilst minimizing the displacement needed.  With the pontoon structure being inboard of the columns, the compartmentation requirement is less onerous, which results in a substantial reduction of lower hull steel weight.  The deep draft during operation provides for SCR friendly motions.  The CP semi is easily scalable for the desired payload and can be used for a standalone or as hub facility.  The CP semi can be used in conjunction with wet trees and/or dry trees.
