A multi–level system for ensuring the reliability of marine mechanical systems at the stages of the life cycle

The operation of vessels in the waters of the Northern Sea Route imposes additional requirements on ship mechanical equipment in accordance with Chapter 6 of the Polar Code. The most urgent scientific tasks include the following: designing new iceclass vessels for operation in the Arctic and extending the service life of the existing Arctic fleet, which should ensure operability at low air temperatures. Forecasting the service life of marine mechanical systems, taking into account the effects of external cyclic loads and the marine corrosive environment, is a complex complex task, for which it is necessary to consider all stages of the life cycle from design to the moment of termination of their operation. In order to improve the existing methods of reliability assessment, accidents on ships operating in Polar waters were considered. A resource management program is proposed that allows you to systematize organizational and technical measures not only during operation, but also allows you to make forecasts at the design stage. A risk management program is proposed that allows you to link organizational and technical measures aimed at identifying the elements of marine mechanical systems that most need attention, thereby effectively distributing maintenance. At the stages of the life cycle, a multilevel reliability assurance system is proposed, including three levels of assessment: reliability management; resource management and risk management.
