The Total Energy and Emissions Analysis for Marine Systems Model

The Total Energy & Emissions Analysis for Marine Systems Model (TEAMS) is the first-ever model able to calculate total fuel-cycle emissions and energy use for marine vessels. TEAMS captures "well-to-hull" energy use and emissions - that is, energy and emissions along the entire fuel pathway (extraction -> processing -> distribution -> use in vessels). TEAMS conducts analyses for six fuel pathways: (1) petroleum to residual oil; (2) petroleum to conventional diesel; (3) petroleum to low-sulfur diesel; (4) natural gas to compressed natural gas; (5) natural gas to Fischer-Tropsch diesel; and, (6) soybeans to Biodiesel.

TEAMS calculates total fuel-cycle emissions of three greenhouse gases (carbon dioxide [CO2], nitrous oxide [N2O], and methane [CH4]) and five criteria pollutants (volatile organic compounds [VOCs], carbon monoxide [CO], nitrogen oxides [NOx], particulate matter with aerodynamic diameters of 10 micrometers or less [PM10], and sulfur oxides [SOx]). TEAMS also calculates total energy consumption, fossil fuel consumption, and petroleum consumption associated with each of its six fuel cycles. TEAMS can be used to study emissions from a variety of user-defined vessels, including cargo ships, passenger ferries, and container ships.

TEAMS is available to download and use free of charge. To download TEAMS, go to the downloads page.



September 2007

TEAMS Version 1.3 has been released and posted to the website for download. The case study files and user guide have also been updated to reflect the new version of the model. Thanks to the California Air Resources Board (CARB) for their excellent feedback prompting the new version of the model.

January 2007

The TEAMS project has been published in the January issue of the Journal of the Air & Waste Management Association. Go here to access the abstract and full article.
