The invention relates to a marine cathodic protection monitoring system comprising an on-board internal monitoring unit (113; 213) arranged to receive measurement data from a submerged external unit (108, 109; 208, 209; 300; 500; 600; 700; 800; 900). The external unit is mounted in direct contact with a cathodically protected structure (310) and which external unit is powered by a dedicated source of power (308; 508; 608; 612; 613). The external unit comprises reference electrodes (301; 501; 601; 701; 801; 901) arranged in electrical connection with the cathodically protected structure (310), a voltmeter (302; 502; 602) arranged to monitor the potential difference and means for at least transmitting data (303; 503; 603) using a wireless protocol. The external unit (108, 109; 208, 209; 300; 500; 600; 700; 800; 900) is arranged to transmit measurement data indicating the current potential difference of the structure.
