Some aspects of ensuring operational reliability of power plants of marine autonomous surface ships

This article examines the features of marine propulsion systems (MPS) of autonomous marine ships (MASS) and the factors affecting their reliability. It was noted that the key feature of the MASS MPS is zero maintainability during the voyage, as a result of which a non-critical failure under normal conditions can escalate into an unacceptable accident. Ensuring the reliability and safety of MASS will inevitably require maximum automation of the ship’s propulsion system, regardless of its configuration, maintenance planning, as well as a significant increase in the reliability of propulsion system components. The authors analyze the potential for marine energy development and consider the most suitable MASS propulsion system configurations in terms of the system configuration and engine room equipment operating conditions. To substantiate possible MASS propulsion system type and configuration options, existing regulatory documents in this area are also reviewed. The purpose of this article is to examine the characteristics and required properties of MPS for MASS and to identify the MPS types and compositions that best meet these requirements.
