AN INTEGRATED APPROACH TO RISK ASSESSMENT OF FLETNER ROTORS ON MARINE VESSELS

Abstract

This article examines the assessment of risks associated with the use of Flettner rotors on seagoing vessels as elements of wind-assisted propulsion in the context of implementing energy-efficient technologies in modern shipping. The relevance of the study is justified by the need to reduce fuel consumption, cut greenhouse gas emissions, and ensure the safe integration of alternative propulsion systems into ship power plants. An analysis of current scientific approaches to assessing the efficiency and safety of Flettner rotors was conducted; it was found that existing studies are primarily focused on the aerodynamic and energy characteristics of the system, while issues of comprehensive risk assessment remain insufficiently developed.

An integrated approach to risk assessment is proposed, combining hazard identification procedures, FSA principles, HAZID/HAZOP elements, and the quantitative determination of an integral risk indicator. Within the scope of the study, risks were systematized into the following main groups: technical, aerodynamic, navigational, operational, human-related, as well as regulatory and environmental. It was established that aerodynamic and navigational factors have the greatest impact on the overall risk level, as they determine the vessel’s seakeeping, maneuverability, and system stability under various operating conditions.

A framework for an integrated risk indicator has been developed that takes into account the probability of hazardous events occurring, the severity of their consequences, and the relative importance of individual risk groups, thereby enabling a formalized assessment of the safety of using Fletner rotors for various types of vessels and operational scenarios. The practical significance of the obtained results lies in the possibility of using the proposed methodology during the design, technical integration, operational control, and preparation of recommendations for risk minimization when implementing wind-assisted propulsion technologies in maritime transport.
