Russian passenger vessels get new lease of life with DEIF PPM-3

New lease of life for Soviet-era vessels

The ship series was built from 1974 to 1983 (“Project 301”) and from 1983 to 1992 (“Project 302”) at the VEB Elbewerft Boizenburg/Rosslau Boizenburg shipyard in the former German Democratic Republic (GDR). The vessels were built on the orders of the Soviet Union and were intended for operation in the North-West Volga, Moscow, White Sea-Onega, the Volga-Don, and Kama for the Russian Amur Shipping Company. The ships became the first mass-produced series of vessels of this class in the former USSR.

Nowadays, the vessels (which can accommodate up to 360 passengers) sail tourist routes from Moscow to St. Petersburg, Moscow to Astrakhan, other routes on the Volga, and from Kiev to Odessa. They are also used on shorter routes from St. Petersburg to Valaam, from Moscow to Uglich, and from Kiev to Kanev. In between voyages, the ships are used as floating hotels.

Several benefits from the PPM-3 upgrade

The retrofit project for the series (which includes 25 ships) has been ongoing since 2013. The upgrade operations are being carried out by DEIF’s Russian distributor DVK-Electro and by different Russian marine integrators: MNS, Volgara, and Sudovoy Servis. The original power management system on the vessels is being upgraded to the DEIF PPM-3 system which performs the following functions:

• Management, control, and protection of the motor and generators
• Synchronisation of the generator to the main switchboard busbars and distribution of active power between the four diesel generators
• Load-dependent start/stop of generating units
• Setting the priority of the generating units at launch
• Automatic generator start-up in case of blackout
• Shore connection synchronisation and operation
• Logging of power plant alarms and events
• Disconnection of non-essential consumers
• Heavy consumer control of two powerful 370 kW thrusters and a 150 kW compressor
