CREATION OF A DECISION SUPPORT SYSTEM FOR THE INTEGRATED SECURITY OF TANKER-GAS CARRIERS
The article deals with the construction of a decision support system for the crew for the integrated security of tankers involved in the maritime transport of liquefied gases. In this case, it is proposed to use a two-level version of building a decision support system. At the first level - diagnostic - continuous monitoring and processing of the main parameters of each of the ship’s technical means that affect the level of safety on the ship. These functions, depending on the types and models of the specific equipment, are realized either using the standard means of self-diagnosis of equipment, or with the use of additional technical solutions. At the second level - analytical - the received diagnostic information is processed in the intellectual analytical system, within which simulation simulations of current processes are performed to identify negative prospects for changing operating parameters and parallel verification of combinations of diagnostic parameters in accordance with analytical algorithms and the accumulated knowledge base allowing At an early stage to identify the development of adverse situations. The Decision Support System is designed to provide comprehensive security for tanker gas carriers, which allows the crew to promptly make a decision in the event of potentially dangerous situations on the tanker, due to a lack of operational knowledge and the crew’s inability to handle extreme control. The built decision support system differs from the existing ones in that it allows to control a number of important diagnostic functions and analyze the change of technical parameters with the detection in the early stages of hidden defects and possible malfunctions of ship’s technical means, as well as to predict and prevent potentially dangerous situations that may influence To reduce the safety of tanker-gas carriers. As a result of functioning of the built decision support system for the crew of the tanker-gas carrier, specific recommendations are developed and displayed that allow to avoid dangerous and emergency situations beforehand during the transition or during the performance of cargo operations.
