Worldwide Survey and Characterization of Commercial Marine Fuels

The quality and availability of distillate fuels in the coming decades has become an increasing concern to the U.S. Navy. In response, the Energy Research and Development Office of the David Taylor Naval Ship Research and Development Center (DTNSRDC) has conducted a worldwide survey of commercial marine fuels.

An effort was made to obtain 50 commercial marine fuel samples from various suppliers worldwide. The purpose of the survey was to assess the current quality of available fuels by analytically characterizing each of the fuel samples obtained. This assessment consisted of the measurement of more than 44 fuel properties.

This paper contains a summary of the analytical results which were obtained. In addition, the current analytical results are compared with refinery specifications, with the current Navy specification, and with the results of a similar survey conducted in 1983. Finally, the resulting conclusions and recommendations are presented.
