The invention relates to a floating construction, comprising two elongated rigid steel columns, which are rigidly connected to each other by means of a rigid steel cross connection, the length of said columns being at least 50 meters, and a clear passage with a width of at least 16 meters being bounded between the columns, while near one end each of said columns comprises a buoyancy-providing chamber and near the opposite end each of said columns comprises a ballast, and between those ends a fixing point for a position-determining connection, such as an anchor line, is present on each of said columns. The invention further relates to a platform construction comprising such a floating construction, and also to a method for placing a floating platform construction at sea and a method for removing a platform construction at sea. |
