6.2.2.3.1 tabters arid documentation
Terminals are responsie for the operation and proving of their meters In accordance with ISO 7278 and should ensure that appropriate meter-proving data are available. Meter measurement documentation should be provided for each custody transfer. Terminal operators or inspectors who are aware 01 meter difficulties which could affect accuracy should immediately report the problem to all parties involved In the custody transter Record the problem and its resolution In the inspection report,
Prior to loading, record the opening meter readings. It is strongly recommended that meters be proved doring loading in accordance with International Standards. A completed meterprO%flng report and metetmeasuienieflt documentation for each meter used should be attached to a completed meter report.
If sliore•tank measurements can be taken, show comparison of metered volumes to shoreIank volumes, preferably on volumes displacing the full height of the tank. If volumes cannot be reconciled, check meter factors and shore- tank measurements.’calcuLalions. Record the results in the report
To avoid the entrainment of air in meter assemblies, tanks from which crude petroleum is being with&awn should not be operated below minimum dip (usually 2 m). For floating-root tanks, this level will be above the cntical zone.
6.2.2.3.2 Dynamic temperature measurement
The accuracy of the temperature probe in the snore line should be vent ed from calibrationproving records.
6.2.2.4 SamplIng arid sample handlIng
6.2.2.4.1 Manual samples from loading tanks
Each tank to be used in the loading should be sampled in accordance with ISO 3170.
NOTE 1 The tank contents should be as homogeneous and as sludge- and water-free as possible.
NOTE 2 Tank sarrqles should not be composited prior to analysis. Alter analysis in the laboratory. they may be composded,
II composing Is carfled out alter analysis It should be camed out In accordance wtlh ISO 3170.
6.2.2.4.2 AutomatIc In.lIn. sampling
Automatic in-line samplers should be installed and operated in accordance with ISO 3171.
Manual tank samples before loading should be taken to back up a failure of the automatic sampling device.
6.2.2.4.3 Dlsliibutlon and retention of loading tank samples
Sufficient samples should be obtained to meet the requirements of interested parties and regulatory agencies. Sampling arid testing requirements are generaly specified by interested parties.
Identical samples should be provided br
— the loading terminal.
— the cargo owner via the vessel’s master, independent inspectors, and
— all other parties designated to receive them, and which may include the vessel owner.
