Research interest area

Since 2021, the Department of Marine and Inland Power Plants has been operating under a changed name - the Department of Marine Power Plants. The basis of the research and teaching infrastructure of the plant are three laboratories, in which most research and experimental work is carried out: the Fuels and Lubricants Laboratory, the Laboratory for Diagnostics of Piston Engines and Compressors and the Laboratory of Ship Machines and Systems.

Currently, the full-time staff of the department consists of nine academic teachers. The teaching team consists of a titular professor, habilitated doctor, five doctors and two masters with open doctoral theses. Each teacher specializes in scientific issues related to the design and operation of machinery and equipment for complex energy systems of marine power plants and various types of ocean engineering facilities.

The department conducts classes and research in the field of designing marine power plants and their systems. This activity includes: designing marine power plants with regard to reliability, diagnostics and safety of their operation, as well as decision-making control of the operation process of marine internal combustion engines, taking into account selected optimization criteria.

In 2007, the plant resumed the publication of the Journal of Polish CIMEEAC, which includes, after receiving positive reviews, publications related to the subject of the periodic International Scientific and Technical Conference EXPLO-DIESEL & GAS TURBINE - Maintenance of compression ignition and gas turbine engines, taking into account environmental protection.

This journal was created in response to the needs of the scientific community participating in the conference and refers to the subject of CIMAC (International Congress on Combustion Engines). The journal is an annual consisting of two to four issues.

Laboratory base

Multi-machine laboratory stand

The laboratory stand consists of four independent sets of machines:

  • Andoria S320 four-stroke diesel engine set with a brake enabling the engine to be loaded in the entire range of its performance field with an in-built torque converter and rotational speed sensor.

Dedicated brake measurement and control system enables full automation of tests that is:

  • programming of research cycles,
  • program engine control - regulation modes that enable operation at a constant speed and constant torque controlled by a dose of fuel or rotational speed,
  • acquisition and archiving of research results.
  •  A set of a Faryman type D10 four-stroke diesel engine, powered by a DC generator, adapted to measure internal cylinder pressures with the use of standard indicators and optical pressure sensors by Optrand.
  • Fuel and oil centrifuges MAB104B-24 with accessories.
  • a station for testing pumps and heat exchangers.
Mobile diagnostic system

The diagnostic system includes the following measuring instruments:

  • digital cylinder pressure indicator LEMAG PREMET C by LEHMAN & MICHELS GmbH
  • XLG3 measuring video endoscope from EVEREST VIT - enabling inspection of internal spaces of industrial machines and devices, closed construction profiles (e.g. tanks), etc., through existing or specially made technological openings with a diameter of more than 7 mm.
  • SVAN 956 digital recorder and vibration analyzer by SVANTEK
  • Multi-channel analyzer of the dynamic condition of rolling bearings using the SPM LEONOVA EMERALD shock pulse method
  • TESTO 350 exhaust gas analyzer for long-term measurements of the chemical composition of exhaust fumes from marine engines
  • TESTO 400 thermohygrometer
  • NEC THERMOGEAR G30 thermal imaging camera
Laboratory of Fuels and Lubricants

The scope of laboratory tests offered by the Fuels and Lubricants Laboratory:

  • laboratory tests of physico-chemical properties of lubricating oils and liquid fuels
  • identification of the technical condition of the main functional systems of internal combustion engines and compressors based on the results of diagnostic tests
  • evaluation of lubricating properties and examination of the influence of oils and greases on surface fatigue wear, the so-called spaling and pitting of elements working on a highly loaded lubricating contact. The tests are performed on the T-02 and T-03 four-ball apparatus manufactured by the Radom Institute of Technology and Operation
  • kinematic and dynamic viscosity measurements of fuels and lubricating oils using the kinematic viscometer VC012 Visco Clock by SCHOTT GERATE GmbH and the rotational (digital) viscometer DV-1P by Anton Paar GmbH
  • measurement of TBN base number and water content with an electrochemical cell and acid number determination kit from Kittiwake Development Ltd.
  • measurement of flash point and flame point using the HFP 386-Cleveland by WALTER HERZOG GmbH and the HFP 380 - PENSKY-MARTENS by WALTER HERZOG GmbH
  • determination of the density of oils and fuels using the portable DMA 35N PETROL apparatus from Anton Paar GmbH
  • determination of the dropping point of lubricants and the separation of oil from lubricants using an apparatus from Petrotest Instruments GmbH & Co. KG
Stand for energy research of rotary mechanical systems
  • The stand was built on the basis of a SCHENCK testing machine, originally designed to carry out tests to determine the fatigue limit of construction materials when bent on both sides. The main advantage of the fatigue machine is the uniform loading of the sample along its entire length with a pure bending moment, which may correspond to the operation of the drive shaft under conditions of loss of shaft alignment. As in the full-size drive system, the rotational speed of the Schenck machine is stabilized. During the operation of the physical model, the following measurement signals are observed:
    • rotational speed and torque at the place of its measurement,
    • vibration acceleration, acoustic emission,
    • deflection of the drive shaft,
    • voltage and current of the electric drive motor,
    • thermograms of bearing nodes with a connecting drive shaft.
Laboratory of Safety, Reliability and Diagnostics

A computer lab that offers a wide range of possibilities for its use both for teaching and research purposes.

Considering the hardware, there are currently 15 workstations working in the local network and the operator's console (together with the computer that supports it) of the MER / MEC ship engine room simulator by Unitest.

The hardware equipment also enabled the installation of the following UNITEST gym simulator packages:

  • LER3D - power plant simulator with a low-speed main drive motor
  • MED3D - engine room simulator with a medium-speed main drive motor
  • DE3D - diesel-electric marine drive system simulator
  • The autonomous auxiliary software package "Marine Trening Software" enabling interactive teaching of the principles of operation of basic equipment and installations of engine rooms and general ship systems
  • Turbo Diesel 5 diagnostic simulator

In addition to the above-mentioned, electronic versions of technical documentation of ship devices and equipment have been installed on the computers.
