2.12.3.3 TANK INSPECTION PRIOR TO LOADING

A special check should be made of the tanks and the results recorded in the respective log or form under the SMS.
This may include
  • tank atmosphere
  • tank cleanliness/suitability for loading
  • pipes, including manifolds
  • if heating coils are to be used, these should be tested for leaks prior to loading
  • crude oil washing system/tank washing system
  • inert gas system, pressure/vacuum valves
  • cargo valves settings
  • packing and securing of all tank hatches
  • manifolds and packing
  • valves and gaskets
  • if more than one grade is to be loaded, all segregation valves should be tested and blind flanges inserted where possible. Consideration should also be given to the need for segregation of the vapour lines.

    Precautions against hazards such as static electricity should be taken when handling static accumulating cargoes in a non-inert atmosphere. In particular, caution is required with regards to safe flow rate, ullaging, sampling and gauging procedures. For further details please see International Safety Guide for Oil Tankers and Terminals (ISGOTT).
