Strategies and measures for reducing maritime CO₂ emissions
(Doktoravhandlinger ved NTNU, 1503-8181; 2013:201, Doctoral thesis, 2013)CO2 emissions from maritime transport represent 3.3% of global anthropogenic CO2 emissions. These emissions are forecasted to increase by 150% - 250% up to 2050, due to increased freight volumes (Buhaug et al., 2009). ... -
Strategies on Methane Slip Mitigation of Spark-Ignition Natural Gas Engine during Transient Motion
(Peer reviewed; Journal article, 2021)The liquefied natural gas (LNG)-fueled ships were provisioned to meet the strict emission legislation in the marine application since 2000. However, the scientific approach of burning the low-emission natural gas in lean ... -
Stratified flow over complex topography: A model study of the bottom drag and associated mixing
(Journal article; Peer reviewed, 2012)The flow of stratified fluid over complex topography may lead to a significant drag on the fluid, exerted by the bottom obstacles. Using a 2-m resolution, three-dimensional, non hydrostatic numerical ocean model, the drag ... -
Streamlined semi-automatic data processing framework for ship performance analysis
(Peer reviewed; Journal article, 2023)The hydrodynamic performance of a sea-going ship can be analyzed using data from different sources, like onboard recorded in-service data, AIS data, and noon reports. Each of these sources is known to have its inherent ... -
