184.108.40.206 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 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).
