TRANSMED is a submarine pipeline gas transportation system crossing the Sicily Channel, in the Mediterranean Sea, at a maximum water depth of 610 m. It went into operation in 1981. Initially composed of three lines, it has been increased to five lines and to a total length of 780 Km in the last year. In the present paper criteria, methodology and equipment used for the periodic inspection surveys of TRANSMED and for the management of gathered data are presented. The twelve years inspection activity and the relevant results of data analysis, mainly the historical evolution of scour induced free spans and the incidence of other hazards, are illustrated. Moreover, the critical aspects concerning data acquisition, processing and management are analyzed and the planned developments are presented.
