The article focuses on the importance of organizing the ship operators training, who control the operation of systems protecting the sea vessels from corrosion. There are presented the results of a scientific research - control of the operation of the tread protection system of the steel hull of an auxiliary marine vessel (floating workshop PM-15), which is in a long-term standby mode. The potential difference between the ship's hull and two reference electrodes was measured at a given control point. The control measurements have been carried out using the reference electrodes: silver chloride reference electrode recommended for use by regulatory documents and zinc reference electrodes (not recommended by regulatory documents for sea vessels). There have been made 50 parallel control measurements. The time interval between parallel measurements was 5 seconds. Control measurements were performed within 5 days from 07.02.2020 to 07.14.2020. The accuracy of the control measurements was assessed in accordance with regulatory requirements. It has been stated that both reference electrodes provide high accuracy of control measurements; the results of control carried out with the help of zinc reference electrodes are highly stable. It has been inferred that zinc reference electrodes can be used on Russian ships to control the tread protection of the ship's hull and can be recommended for using by ship crews for training ship operators of ship corrosion protection systems.
