Electric engineering & technology

We have a great experience in design, production, tests, delivery & on-board adjustment of fully electric propulsion systems (integrated electric power systems with electric propulsion). These systems are integrated complexes of gears and electric equipment with the common source of electric power for supply of propulsion units and shipboard users. TSNII SET has produced, tested and installed fully electric propulsion systems on tugboats (projects 745 & 22030), hydrographic survey vessels (projects 19910 & 19920), rescue vessels (projects 21300 & 20180).

TSNII SET is continuously improving the integrated electric propulsion systems. Our R&D efforts are focused on tackling practical issues. The projects performed under federal target programs (funded from the state budget) and contracts with customers are based on consistent and goal-oriented approach. TSNII SET developments include:

  • ship electric propulsion systems with a power range of 1.5–8.5 МW delivered at propeller;
  • ship electric propulsion systems with a package of electric equipment for pod, power output up to 3.5 MW;
  • engineering design projects with running mock-up models of automated local control systems for fully electric propulsion systems intended for a range of ship types;
  • techniques & hardware for protection of fully electric ships against uncontrolled behavior at tripping of converters and propulsion motors.

There is an on-going process of developing the monitoring technologies and systems for technical diagnostics of electric equipment of integrated electric propulsion systems for commercial ships and marine structures, effort are undertaken to develop the integrated electric propulsion systems of 5–25 MW, voltage 6.3 kW.

TSNII SET is also actively engaged in developing individual electric equipment for ships, vessels and marine structures:

  • static converters of various types for power range 50–3000 kW;
  • main switchboards for low (under 1000 V) and high (above 10 500 V) voltage;
  • emergency switchboards;
  • sub-switchboards for voltages under 1000 V;
  • automated control systems for individual machines, electric power systems and entire processes;
  • package of frequency-controlled motors for various machinery of platforms, power output 5–700 kW.

Frequency converters

TSNII SET is also a leader in the development of structural/mounting details (water-tight entries, penetrations, cable connections, etc.) as well as on-board installation techniques. This kind of fittings were supplied to deep-water submersibles of projects 16810 and 16811 (the latter beat the diving depth record for Russian underwater vehicles — 6270 m).

In this area TSNII SET is continuously improving structural/mounting arrangements based on R&Ds. We have worked out and continue to develop installation techniques for novel halogenless cables noted for higher reliability and fire safety, industrial processes for large-scale production of flameproof tight penetrations for inter-compartment transit of power and weak-current cables.

Another promising field is development of electrostatic blast & fire protection. We have developed an electrostatic blast & fire protection system for storage and transportation of crude oil and oil products produced off-shore.

Electrostatic blast & fire protection system

Modular concept of integrated full electric propulsion (IFEP) systems

The modular IFEP concept is based on standard electric equipment modules, which can be assembled to build up the desired system. The modular concept makes it possible to use a minimum number of standard equipment units to configure powering systems with customized specifications (power, voltage).

The modular IFEP design combined with advanced power estimation techniques enable optimization of the ship powering architecture as suites best the type and design specifications of the ship in question.

Advantages of modular IFEP design:

  • Reduced cost and duration of design.
  • Easy-to-manufacture IFEP system.
  • Easy to upgrade and repair.
  • Higher reliability of IFEP system.
  • Standard and unitized parts of system.
  • Easy to configure IFEP system to match any required voltages and tasks using a standard set of hardware.

Ship’s Fiber Optic Digital Data Network (FODN)

Ship’s fiber optic digital data network is made up of ship’s data communication units (DCU) located in the key ship compartments equipped with intelligent devices and automatic hardware. The intelligent devices are linked to DCU with copper duplicated communication lines arranged within one compartment.

FODN is intended to ensure reliable data exchange between all networked devices. Ethernet interface is used for data communication. The double-loop configuration with two independent fiber optic loops ensures robustness of the network. Data are sent by program via two (primary and backup) channels and can also be received from two channels. The data received from the channel currently assumed to be the primary one is accepted as valid. In case of failure in communication with any network unit the channels are switched. This feature provides enhanced reliability because each network unit is able to operate via either channel at different sections of the data transfer line.


  • common use, versatility and compatibility with modern controllers, computers and other smart devices;
  • convenient and high-speed transmission of large data volumes;
  • independent of line length (with reference to ship dimensions);
  • immunity to electromagnetic interferences;
  • high level of reliability and robustness;
  • fully functional even in case of multiple circuit breaks at different locations or failure of any network unit;
  • self-diagnostic function.

Hydrogen power engineering

TSNII SET has many years of experience in the development of fuel-cell power plants including special-purpose systems, we operate up-to-date research & production facilities and test sites and have a stock of forward-looking solutions in the field of hydrogen power engineering. The notable projects accomplished in recent years are:

R&D «Hybrid power plant with solid polymer fuel cells»

In 2011, under the federal target program «Development of civil marine technologies for 2009 — 2016», we have completed the project in development of a ship hybrid power plant in the power range of 250 — 2500 kW.

Hybrid power plant with solid polymer fuel cells

Hybrid power plants with solid polymer fuel cells (SPFC) are primarily intended for ships projected for oil & gas prospecting, production and shipment in the Far North. The main advantages of SPFC hybrid plant as compared to diesel-generator, gas engine and gas turbine plants are as follows:

  • low operation costs due to the highly efficient electro-chemical conversion of thermal energy (efficiency of electro-chemical generator ~ 50%) combined with efficient waste heat recovery using conventional machine converters (efficiency of electro-chemical generator + 20%) as well as the possibility of using the carried hydrocarbons as own fuel;
  • high maneuverability of electrochemical generators in the entire load range;
  • drastic cut-down of harmful emissions.

A demonstrator model of 60 kW hybrid ship powerplant module was produced on the basis of a highly-maneuverable low-temperature electrochemical generator with solid-polymer fuel cells (МGEU-60). It presents the basic design solution intended to produce a range of hybrid (combined) powerplants for ships operating on hydrocarbon fuel.
