Ship propulsion, machinery and systems

Paper

The harvesting of wind energy and its transformation into a thrust force for ship propulsion is gaining in popularity due to the expected benefit in emission reduction. To exploit the benefit a proper integration between the conventional diesel engine-screw propeller propulsion plant and the wind-assisted plant is mandatory. A mathematical model describing the behaviour of the rotor in terms...

29. A digital twin approach to the diagnostic analysis of a marine diesel engine

Ship propulsion, machinery and systems

Paper

Marine diesel engines are systems integrated into a complex ship’s propulsion plant and comprehensive diagnostic analysis of possible degradations and failures is very challenging. Nowadays, current software and hardware allow exploring innovative ways, although every methodology cannot be separated from an adequate onboard monitoring system. In this work, the effects of several typical...

30. Sensitivity analysis of a marine gasoline engine: from power to emissions

Mrs Luigia Mocerino (University of Naples “Parthenope")

Ship propulsion, machinery and systems

Paper

Numerical simulations currently represent a valid aid to assess the performance of marine engines. Anyway, most of past applications generally focused on large supercharged 4-stroke diesel engines, while few results are available in the literature for fast outboard engines, generally installed onboard of recreational crafts. Therefore, a case study on a fast outboard diesel engine (4T, 6300...

37. Classifying the Innovation: The Certification of New Designs for Power Generation, Conversion and Energy Storage Focusing on the Reduction of Ships Emissions

Matteo Roiaz (Lloyd's Register)

Ship propulsion, machinery and systems

Paper

In recent times the ship building and yacht industries have seen a surge in the requests for the application to the power generation, conversion and energy storage of technologies which were previously reserved to land-based uses or to niche sectors such as space, military, and scientific research. Such requests are often driven by seeking cleaner exhaust emissions, more efficient fuel...

66. The study of an innovative propulsion plant for a High-Speed Catamaran Ferry for decarbonisation in the marine industry

Mr Alessandro Taylor (Naval Architectural Services Ltd.)

Ship propulsion, machinery and systems

Paper

This paper supports decarbonisation in the marine industry by illustrating that a proper design methodology and state of the art technologies can significantly reduce greenhouse gas emissions.
In particular the paper aims to demonstrate the possibility of reducing the environmental footprint of Marine High-Speed passenger transportation with an innovative propulsion plant design. The...
