Bibliographic description: Belyashov V.A., Vasilev N.V., Makarov V.V., Pautov L.G. Innovative developments of Krylov State Research Centre to improve the safety and reliability of vessels with podded trust units in extreme ice conditions. Arctic: ecology and economy, 2018, no. 1(29), pp. 92-103. DOI: 10.25283/2223-4594-2018-1-92-103. (In Russian).
The increasing demands to safety and reliability of vessels in ice conditions requires new approaches to ensure the reliability of the propeller.
Traditional passive approach involves the creation of a constructive margin of the blades. The resulting significant decrease in their efficiency on pure water, however it does not guarantee against damage due to high uncertainty of loads, characteristic for extreme ice conditions. The problem is compounded by the widespread use on icebreaking ships podded thrust units (POD), much more vulnerable and much less studied in ice conditions than the propellers on the shafts coming out of the hull.
In addition to the traditional proposed a proactive approach based on the comprehensive monitoring of parameters of the propulsion and use of monitoring data in control system of ship motion. This approach will allow us to assess both the technical status and the operating mode of propulsion and use these assessments to identify and putting the ship out of dangerous situations.
Presented the latest developments of Krylov State Research Centre for the implementation of the proposed approach in relation to modern icebreaking vessels with the POD: built-in system of comprehensive monitoring of the RMC, ensuring the collection of objective data and evaluation of current operating mode and technical condition of the POD; intelligent control system of ship motion, able to use monitoring data for safe withdrawal of the POD and of the vessel from a dangerous situation.
Together, these two systems will reduce the risks of breakdowns of the POD due to prevent the escalation of dangerous situations in an emergency and to save technical resource of the POD by reducing working time in dangerous and emergency modes.
