The casing is connected to a wellhead partly arranged above a surface of a ground or on the seabed and the wellhead is adapted to seal off an interior part of the casing. The system comprises an inspection device adapted to inspect the wellhead and/or an upper part of the casing and the inspection device comprises at least one transmitter unit and at least one detector unit. Moreover, the system comprises lowering means for lowering either the transmitter unit or the detector unit down through the wellhead into the interior part of the casing.
