Mean value first principle engine model for predicting dynamic behaviour of two-stroke marine diesel engine in various ship propulsion operations

Analysis of ship propulsion system performance is often performed using detailed hydrodynamic models to assess load changes, which are subsequently compared to static engine limits, or by detailed engine models that are rarely integrated with sufficiently detailed propulsion models for load change estimation. To investigate the dynamic engine...

Effects of adverse sea conditions on propulsion and manoeuvring performance of low-powered ocean-going cargo ship

Current EEDI (Energy Efficiency Design Index) regulations striving to reduce the installed engine power on new ships for a low EEDI may lead to underpowered ships having insufficient power when operating in adverse sea conditions. In this paper, the operational safety of a low-powered ocean-going cargo ship operating in adverse sea conditions...

Energy Effectiveness and Operational Safety of Low-Powered Ocean-going Cargo Ship in Various (Heavy) Operating Conditions

The shipping industry, which remains the backbone of international merchandise trade, is striving to reduce its operational cost and more importantly its environment impact. New ships need meet the EEDI (Energy Efficiency Design Index) requirements of IMO (International Maritime Organization). However, the current EEDI is not able to accurately...

Fuel consumption and emissions of ocean-going cargo ship with hybrid propulsion and different fuels over voyage

Hybrid propulsion and using liquefied natural gas (LNG) as the alternative fuel have been applied on automobiles and some small ships, but research investigating the fuel consumption and emissions over the total voyage of ocean-going cargo ships with a hybrid propulsion and different fuels is limited. This paper tries to fill the knowledge...

Mean value modelling of diesel engine combustion based on parameterized finite stage cylinder process

Mean value diesel engine models are widely used since they focus on the main engine performance and can operate on a time scale that is longer than one revolution, and as a consequence use time steps that are much longer than crank-angle models. Mean Value First Principle (MVFP) models are not primarily intended for engine development but are...
