Corrosion is one of the basic reasons of the ship hull strength retrogression; therefore, it is necessary to control the operational mode of the systems of the ship steel hull electrochemical prevention from corrosion. At the same time, it is necessary to estimate the ship steel hull potential function by means of mobile mill voltmeter and standard reference silver-chloride electrode. However, the advisable for the usage reference silver-chloride electrode is characterized by the volatility of the potential function. Therefore, it is necessary to check occasionally its operability by means of the standard reference silver-chloride electrode. But it is impossible to prepare the reference silver-chloride electrode in marine conditions. The necessity of rejection from the usage of the standard reference electrodes while estimating the ship steel hull potential function is explained. It is shown that instead of the reference electrodes the use of ship electro-coal components is practicable, for example, the brushes for electric machines, whose exploitation period is over. The obtained experimental and design data demonstrated that the precision of the results does not worsen while using the brushes for electric machines instead of the reference silver-chloride electrode. It is easy to bring the results of the estimation of the ship hull potential function to the standard norms by introducing the appropriate corrections. Besides, substitution of the reference silver-chloride electrode for the ship electro-coal components will allow controlling the operational mode of the systems of the ship steel hull electrochemical protection effectively. This hypothesis is confirmed by the practical usage of the alternative reference electrodes at the fishing seiner "Charymovo".
