The exploitation of hydrocarbon resources stored in the seabed requires the installation of platforms for the extraction of hydrocarbons from the seabed. In the reference marine area there are 62 active platforms, of which 57 are productive, 4 support production and 1 is not yet operational because it is awaiting the granting of the cultivation concession. The platforms can be simple monotubular structures (connected directly to a single productive well) and often connected to others of the same type to form a single structure (cluster), or platforms of larger dimensions (structures with 4, 6, 8 and 12 legs) sometimes also connected to each other, to which several productive wells are connected and with permanent personnel on board. All these platforms are connected to each other, so that the extracted gas is conveyed to the collection stations, by a dense network of underwater pipelines (sealines).
