Increasing the safety requirements for shipping and shipping ferries requires continuous monitoring of the loading of trains on board specialized vessels. The International Maritime Organization considers it most appropriate to prevent marine casualties resulting from the loss of stability of the vessels. According to IMO studies, numerous ferry accidents were caused precisely by the fact that the weight was incorrectly indicated. Weighing of all trains, which are transported by sea ferries, in the near future will be a reality for companies-operators of freight transport. In order to find ways to improve the situation with heavy control operations on the ferries, the designs of the most common types of weight measuring devices have been analyzed. It has been assumed that a constructive implementation on the basis of fiber-optic and mechanical elements should provide to a measuring device: the absence of additional measures to protect the surface of weighing sensor in conditions of dynamic deformations of ship's hull during loading; the possibility of compensation of fluctuations of the environment temperature; the reliability, sensitivity and simplicity of circuit design solutions of devices of the known types. The circuit design of the weighing instrument, aimed at further improvement of the process of automation of weight control operations is developed. The proposed weight measuring device is characterized in that a weight measuring probe, which is a cylindrical sealed enclosure made of invar with plugs, which contains compensating and measuring fiber optic coils, is located in the regular drilling of the rail. The application of the proposed weighing system, in addition, will increase the level of automation of the measurement and control of weight, increase the discipline of freight traffic, improve the efficiency of technological control and safety of maritime navigation in general.
