following activities are not comprehensive, and are intended as a guide to what
might be necessary to successfully complete this study:
Phase 1 – Compile available test data, develop data structure and
quality ranking criteria
search should be implemented for all available marine vessel test studies and
emission factor programs to fully appreciate available data elements. A data
structure will need to be developed that allows for the inclusion of critical
and ancillary data elements, facilitates user searches, and can provide summary
of the more challenging tasks for this project will be to develop a scoring
method that helps assess the quality of the data included in the database. This will allow the developer to identify
data that are missing or need to be updated and will present the user with access
to the best quality data that is currently available.
Phase 2 – Compile available emission
factors and speciation profiles and score the test data based on the ranking
the data have been compiled into a single database and quality scores assigned
to each record, it will be possible to preform meaningful statistical
assessments of the data specific to the users’ needs. For example, if a user is
interesting in encouraging vessel replacement or the re-engining of older
vessels, this database may be of particular importance in determining how
emission rates change as the fleet ages.
Phase 3. Database testing

database based on comments received from the testers
Phase 4 – Posting the database on the
website and update annually.
posting of the database will need to be made to a secure website. The site should be set up to allow others
involved in engine testing to submit their results electronically. Submitted data will need to be vetted prior
to inclusion in the next update. Search functions will need to be set up to
allow users to easily locate appropriate emission factors. It may be possible to find an academic
institute or government agency that could host the site and help with updates.
