Abstract: A semi-submersible floating platform (1) is configured for supporting and transporting a column structure (2), and comprises a plurality of buoyant columns (4a-c) interconnected by a support structure (5) having an adaptive opening (7) for axial and radial fastening of the column structure (2). Each column (4) comprises ballasting means (16, 17) whereby the draft may be controlled, and each column (4) comprises an active heave motion neutralization system that may be operated independently, such that the platform (1) may be maintained stable and level when handling the structure (2), for example during transit, separation and docking. A method of operating the platform involves the operation of valves (20, 22) to control the pressure inside a reservoir (12) in order to control the water level (11) in a rise canister (30) in one or more of the columns (4a-c).
