Verify that the fill, approximately 2,000 to 5,000 barrels, is pumped into one cargo tank in the vessel.
Request the ship's officer to switch from this tank to the other tanks and continue loading.
If at any time during loading there is an indication of contamination, the loading shall be stopped until the
cause and extent of the contamination has been determined.
Verify that a sample is drawn from the first tank, after a 30 minute wait, and the tests are performed to
determine if the quality of the product being loading is satisfactory.
Verify that when aviation turbine fuel or kerosene is being loaded, loading and inspection procedures of
COMSCINST 3121.3 (series) of 4 March 1977 and COMSCINST 3121.3 (series) Change 1 of January
1978, subject: Safe Handling of Jet Fuels and Kerosene, are followed:
- Prior to loading, all water will be removed from the vessel pipeline and cargo tank.
- Verify that the initial loading rate does exceed 3 feet per second (1,500 barrels per hour through a 12
inch line) through loading lines into the cargo tanks, until the discharge outlet has been covered by at
least 3 feet of the product. Thereafter, the normal loading rate may be resumed.
- Verify that the loading rate of 3 feet per second is applied to the flow of each tank.
- Verify that ullages, water soundings, temperatures, and samples, including the first-in sample, are
not taken of any cargo tank until at least 30 minutes after flow into the tank has ceased. In the
meantime, loading of other tanks may proceed.
Inspecting Loading Procedures for Barges.
Preloading Inspection Procedures. The QSR will ensure the following actions have been taken
prior to approving loading:
Vessel conditioning.
Vessel tank inspections.
Vessel tank/internal rust test.
Vessel loading plans.
Multiport inspection.
Quality and quantity determination.
Loading Inspection Procedure for Barges.
Verify that a sample is drawn from the tank, after a 30 minute wait, and tests are performed to determine
if the quality of the product being loaded is satisfactory.
Verify that samples and tests of the contents of the vessel's cargo tanks during and after loading are
performed to determine product quality.
Monitoring Postloading Procedures for Tankers and Barges.
Witness sampling of vessel cargo tanks.
Monitor cargo tank gaging, temperature determination, and as time will permit, water cuts.
If possible, water will be stripped ashore before the tanker is released.
Determine the quantity of fuel loaded. Quantity of product loaded or shipped will be determined by shore
tank gages.
- Witness shore tank gaging (opening and closing).
- Determine shore and vessel net quantities and ship/shore losses or gains. Tanker and barge
quantities will be based upon shore tank gages. Report and investigate any quantity discrepancy in
excess of 0.5 percent prior to release of the vessel.
Verify that contractor maintains the retained sample for the period designated.
Inspecting Documents Covering Tanker and Barge Loading.
Verify that DD Form 250-1 (Tanker/Barge Material Inspection and Receiving Report) (Figure 2-1),
continuation sheet, and ullage or innage report are completed.
- If product is loaded from more than one tank, list the test applicable to each tank in separate
columns headed by the tank number.
- The date the product in each was approved and quantity loaded from each tank will be indicated in
the appropriate column.
Verify that the distribution of documents is made IAW DFARS, Appendix F, Part 7.
