Abstract

The study is devoted to experimental identifying the critical zones in the maximum values of mechanical strain in ship hull designs. We have chosen the bearing structural elements of the hull which are the most suitable for monitoring the vessel’s overall strength. The foci of elevated values of mechanical strain in the vessels’ hulls are identified by means of the magnetic method of non-destructive testing. We have measured the coercive force of the material in bearing ship structures such as continuous coamings of cargo holds on both sides of the vessel (which appear to be the most accessible and convenient for control in the field conditions). The coercive force of the material allows measuring of the mechanical strain in the ship's structure without destroying it, on the basis of the corresponding correlation between the strained state and the coercivity of the material. The strained state of the tested elements in critical areas is used to determine the technical condition of bearing elements of the entire ship structure. We have proved that automatic monitoring of the technical condition of merchant marine ships during their operation would significantly increase the reliability and safety of the entire marine fleet.
