A floating construction, includes two elongated rigid steel columns, which are rigidly connected to each other by a rigid steel cross connection, the length of the 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 the columns includes a buoyancy-providing chamber and near the opposite end each of the columns includes a ballast, and between those ends a fixing point for a position-determining connection, such as an anchor line, is present on each of the columns. The invention further relates to a platform construction includes 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. |
