METHOD OF MONITORING TECHNICAL CONDITION OF BEARING ELEMENTS OF SHIP STRUCTURE

摘要

A method of monitoring the technical condition of bearing elements of the ship structure relates to methods of determining the technical condition of ship design, and can be used for monitoring carrier elements of ship structures under conditions of their operation. This allows to observe the behavior of the critical areas of ship structure in operation and to predict their service life. In the method of monitoring the technical condition of bearing elements of the ship structure on bearing structural elements sensors are placed, which measure the magnetic characteristics of the material, the value of which is used to determine the technical condition of bearing elements of a ship. First is pre-measured the value of magnetic characteristics of the material in the zones of a bearing element along the ship followed by determination of the distribution of magnetic characteristic of the material of bearing element along the ship under operating loads, based on which critical areas are determined, in which the magnetic characteristics of the material during operational loads is maximum. Now when monitoring the sensors magnetic characteristics of the material are placed in certain critical pre-determined areas of maximum values of the magnetic characteristics of the material, and for monitoring the technical condition the value of magnetic characteristics of the material in the pre-defined critical areas is used. During monitoring of cargo ships as a bearing element in determining the distribution of the magnetic characteristics of the material hold coamings can be chosen. The critical zones of maximum values of the magnetic characteristics of ship and the areas of location of sensors can be determined during the pre-trial operation of a ship in stormy conditions. In addition, the critical zones of maximum values of the magnetic characteristics of ship and the areas of location of sensors can be determined beforehand during cargo and ballast operations. As a magnetic characteristic of the material its coercive force can be used and coercivity sensors can be used as the sensors of magnetic characteristics. The proposed method is important for increasing the reliability of the operation of ships through the timely identification of critical conditions. This will reduce the risk of maritime accidents by plotting an optimal course while navigating in the sea, which is especially important in difficult conditions of operation. This will improve the safety of navigation, which is especially important in storm conditions and other exceptional situations.
