INSTRUCTIONS FOR STATISTICAL SUMMARY
GENERAL. This section of the cruise report has been specifically designed to collect data on
icebreaker fuel consumption, helicopter use and other information used to bill User Agencies
for use of polar icebreakers. The information will also be used to build a data base that will
allow the accurate prediction of user charges. This information will directly affect the level of
funding available to polar icebreakers. Therefore, accurate information in the Statistical
Summary is essential. Information reported in this section, or easily derived from this section,
need not be repeated in other sections of the Cruise Report.
FUEL USE. Daily fuel use will be reported in the table format shown in the example below.
The purpose of this table is to provide a continuous daily record of fuel use with no breaks or
overlaps. A line entry will be made in the table for each day or portion of a day that the ship
is away from home port. The last entry in the table will show a total for the columns.

- DFM expended (in gallons) through main propulsion and auxiliary machinery
since the previously listed sounding. When bad weather or other circumstances
prevent an accurate sounding, estimate the day's fuel use based on the next
available accurate sounding.
- JP 5 expended (in gallons) through main propulsion and auxiliary machinery since
the previously listed sounding. Do not include aviation fuel.
- Date Time Group, to the nearest hour, of the fuel sounding used to compute the
above fuel expenditures. DTGs must be in Zulu time.
- Predominant engine configuration for the 24 hours preceding the DTG of the
sounding. (Best estimate. This will often be a judgment call). For example,
