• HYBRID ENERGY SYSTEM FOR A CLASSIC SHIP POWER PLANT

  Publikacja

  • R. Liberacki

  - Journal of Polish CIMEEAC - Rok 2017

  The article presents a brief overview of hybrid energy systems used on ships. The area of their application is outlined. The benefits of using such systems are also indicated. Then, the classic ship power plant is defined. The most important part of the article is a proposal how to modify a classic engine room by using a hybrid energy system. The idea is: to accumulate a part of electricity in areas where it is allowed to burn...

• Analysis of reliability of redundant ship power plants

  Publikacja

  • J. Rudnicki

  - Journal of Polish CIMEEAC - Rok 2007

  W referacie przedstawiono możliwości wykorzystania teorii procesów semimarkowskich do określania charakterystyk niezawodnościowych złożonych układów napędowych o zadanym stopniu redundancji. Na przykładzie wybranego układu zaproponowano model niezawodnościowy w formie procesu stochastycznego dyskretnego w stanach i ciągłego w czasie. W oparciu o rozkład graniczny procesu wskazano na praktyczne aspekty wykorzystania uzyskanych w...

• REDUNDANCY AS A WAY INCREASING RELIABILITY OF SHIP POWER PLANTS

  Publikacja

  • W. Tarełko

  - New Trends in Production Engineering - Rok 2018

  One of key ways of assuring a high level of reliability of a ship power plant is to design redundancy of its structural elements, for example redundancy of prime drivers, drivelines etc. This paper deals with issues related to the redundancy as a way increasing dependability of the ship power and propulsion systems. Especially, fundamental characteristics of dependability, major design strategies influencing the reliability, and...

• APPLICATION OF REDUNDANCY IN SHIP POWER PLANTS OF OFFSHORE VESSEL

  Publikacja

  • W. Tarełko

  - New Trends in Production Engineering - Rok 2018

  Power and propulsion systems of offshore units must be of a very high level of reliability. The loss of ability to perform functions of their components causes generally to very high economic losses, which may be increased by unused the weather window resulting to postponing the planned offshore operations. To ensure carrying out so expensive offshore operations in the most reliable way, various types of redundancies are built-in...

• Quantumness in Diagnostics of Marine Internal Combustion Engines and Other Ship Power Plant Machines

  Publikacja

  • J. Rudnicki
  • J. Girtler

  - Polish Maritime Research - Rok 2023

  The article provides proof that the diagnostics of marine internal combustion engines and other ship power plant machines should take into account the randomness and unpredictability of certain events, such as wear, damage, the variations of mechanical and thermal loads, etc., which take place during machine operation. In the article, the energy E, like the other forms (methods) that it can be converted into (heat and work), is...

• Comparative analysis of thermodynamic cycles of selected nuclear ship power plants with high-temperature helium-cooled nuclear reactor

  Publikacja

  • N. Szewczuk-Krypa
  • A. Milewska
  • J. Głuch

  - Polish Maritime Research - Rok 2018

  This paper presents a comparative analysis of thermodynamic cycles of two ship power plant systems with a high-temperature helium- cooled nuclear reactor. The first of them is a gas system with recuperator , in which classical gas chamber is substituted for a HTGR reactor (High Temperature Gas-cooled Reactor) . The second of the considered cycles is a combined gas-steam system where working medium flux from gas turbine outlet...

• Limiting distribution of the three-state semi-Markov model of technical state transitions of ship power plant machines and its applicability in operational decision-making.

  Publikacja

  • J. Girtler

  - Polish Maritime Research - Rok 2020

  The article presents the three-state semi-Markov model of the process {W(t): t 0} of state transitions of a ship power plant machine, with the following interpretation of these states: s1 – state of full serviceability, s2 – state of partial serviceability, and s3 – state of unserviceability. These states are precisely defined for the ship main engine (ME). A hypothesis is proposed which explains the possibility of application...
