• POWER EFFICIENCY OF POWER PLANTS ON TRAILING SUCTION HOPPER DREDGERS

  Publication

  • D. Bocheński

  - Journal of Polish CIMEEAC - Year 2016

  This paper presents the notion of operational power efficiency and compares it with the classical definition of power efficiency. There are presented also calculation results of power efficiency for a selected suction hopper dredger and also influence of power system type of suction hopper dredger on magnitude of power efficiency of its power plant has been highlighted.

• Fault detection in measuring systems of power plants

  Publication

  • J. Głuch

  - Polish Maritime Research - Year 2008

  This paper describes possibility of forming diagnostic relations based on application of the artifical neural networks (ANNs), intended for the identifying of degradation of measuring instruments used in developed power systems. As an example a steam turbine high-power plant was used. And, simulative calculations were applied to forming diagnostic neural relations. Both degradation of the measuring instruments and simultaneously...

• Analysis of reliability of redundant ship power plants

  Publication

  • J. Rudnicki

  - Journal of Polish CIMEEAC - Year 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...

• APPLICATION OF REDUNDANCY IN SHIP POWER PLANTS OF OFFSHORE VESSEL

  Publication

  • W. Tarełko

  - New Trends in Production Engineering - Year 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...

• REDUNDANCY AS A WAY INCREASING RELIABILITY OF SHIP POWER PLANTS

  Publication

  • W. Tarełko

  - New Trends in Production Engineering - Year 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...
