The analysis of operation and failures of a power plant on high-speed vessels with semi-submersible propellers

Over the past century, shipbuilding has been closely linked to solving the most acute problem of increasing the speed of ships. Builders of high-speed vessels habitually justify this struggle for speed in connection with the requirements of the modern market. In Russia, as well as all over the world, there is a need for modern, high-speed, maneuverable and economical vessels. To meet this need, Almaz Central Design Bureau has developed, the Rybinsk Vimpel Plant has launched a high-speed vessel with semi-submersible propellers of project 12150 "Mongoose". Currently, about 75 ships have been launched [1]. This article analyzes the work of foreign and domestic engines accumulated during the operation of high-speed engines MTU 10V2000M93 (manufactured in Germany), ZVEZDA M470MK-M3 (manufactured in Russia) installed on high-speed vessels of project 12150. In particular, information on the most characteristic failures of the components of the main power plants and the propulsion system as a whole, as well as on the possible causes of the occurrence and development of typical engine failures installed on these high-speed vessels, which allow us to assess the advantages and disadvantages of the power plant used.
