The importance of the engine-propeller model accuracy on the performance prediction of a marine propulsion system in the presence of waves
seattone, simone; Tavakoli, Sadi; Taskar, Bhushan; Vincent Jensen, Michael; Pedersen, Eilif; Schramm, Jesper; Steen, Sverre; Andersen, Poul (Peer reviewed; Journal article, 2020)The shipping industry is the heart of international trading activities and the global economy. Maritime transport contributes to environmental pollution through the emission of greenhouse gases. New mandatory regulations ... -
Influence of Turbocharger Inertia and Air Throttle on Marine Gas Engine Response
Tavakoli, Sadi; Schramm, Jesper; Pedersen, Eilif (Journal article, 2021)Due to the current emission legislation, improving the marine propulsion system performance has received considerable notice. Employing natural gas as the primary energy source presented remarkable attention in the lean-burn ... -
Modeling and analysis of performance and emissions of marine lean-burn natural gas engine propulsion in waves
Tavakoli, Sadi; Saettone, Simone; Steen, Sverre; Andersen, Poul; Schramm, Jesper; Pedersen, Eilif (Peer reviewed; Journal article, 2020)In many vessels, the prime mover is a diesel engine, while the researchers recommended using natural gas as an attractive option to comply with the latest emission legislations. This study aims to analyze the dynamic ... -
Ship Propulsion Dynamics and Emissions Gas Engine Methane Slip Reduction at Dynamic Loads
Tavakoli, Sadi (Doctoral theses at NTNU;2021:261, Doctoral thesis, 2021)Continuous discharging of greenhouse gases into the atmosphere has motivated researchers to develop prime movers for working with less polluted energy sources. The low cost of natural gas relative to diesel and gasoline ... -
Unburned Hydrocarbon Formation in a Natural Gas Engine Under Sea Wave Load Conditions
Tavakoli, Sadi; Vincent Jensen, Michael; Pedersen, Eilif; Schramm, Jesper (Peer reviewed; Journal article, 2020)Although natural gas is documented as a low-emission fuel compared to the other traditional fossil fuels in internal combustion engines, recent research indicates large amounts of methane emission released by lean burn gas ...
