Russia loses its diesel industry

- high RPM in the range from 44 to 118 kWt (auxiliary engines and emergency a diesel engine-generators for ships of all classes and purposes, main engines of river ships);

- high RPM below 5 kWt (engines of life boats, emergency diesel engine-generators).

According to our insiders the problem of medium RPM engines may be solved in the following ways (however, it remains hypothetical from the point of view of the policy of the government regarding the industry):

- expanding the power range of some ship diesel engines on the basis of the concept of double purpose engines (DDN) when creating ship diesel engines with the power of 8-10 thousand h.p. on the basis of the Kolomna engines sized ChN 26/26 and powered 4-5 thousand h.p. on the basis of Ural Diesel Motor sized ChN 21/21;

- when developing new types of engines meeting modern requirements: RUMO (ChN22/28), Barnaultransmash (series BMD ChN ChN15/18); modernizing existing designs of diesel engines for their application in shipbuilding: Ural Diesel Motor (ChN 21/21), Volga Diesel Maminyh (ChN 21/21).

In general technical parameters of the ship engines already reached allow for considering their use on the perspective ships keeping in mind engines’ profitability rate, opportunity of using fuels with high viscosity, good weight / size ratio and life time parameters. However, the parameters of the Russian made diesel engines from the point of view of harmful emissions in the atmosphere remain unsatisfactory. Russian diesel makers neglected this point, therefore now the use of their models on the ships of foreign navigation becomes more and more problematic (except for separate models of licensed diesel engines of BMZ and new developments of Kolomna Plant).

Keeping in mind a broad application of the diesel engines in the power units of the domestic ships, Russian naval organizations are interested in constant improvement of engines’ technical and economic parameters, the main of which are: fuel efficiency, reliability, durability, suitability for repair, simplicity of service, vibro-acoustic characteristics, weight and dimensions, ecological safety.

Numerous attempts of Russian diesel enterprises to create co-production with western diesel firms have not yet been successful. Purchase and attempt to arrange the manufacture of the engines under the licenses of foreign firms have not led to the planned results too. The reason is that foreign firms, as a rule, agree on transferring license documentation on the outdated types of engines, even forbidding the export of these engines outside Russia. The only exception is the Nizhny Novgorod based RUMO, which is arranging the production of the licensed engine 6 and 8 ChN 32/40 of the firms MAN B&W.
