Hull Ballast Control Systems

A hull ballast control system is used to control the buoyancy, yaw, roll and position of an offshore platform relative to GPS coordinates by adjusting the buoyancy of individual elements of the hull structure.  Such a system is required because the platform load varies as production volumes in the internal storage tanks increase and decrease and also the impact of ocean currents and weather conditions on the platform must be compensated for in order to maintain desirable positioning.  Following are photographs of a hull ballast control system built by PROTEC.
