removal of blank flanges prior to connection.
A positive means of confirming that both ship and shore cargo systems are
isolated and drained should be in place and used to confirm that it is safe to
remove blank flanges prior to connection. The means should provide protection
against pollution due to unexpected and uncontrolled release of product from
the cargo system and injury to personnel due to pressure in the system
suddenly being released in an uncontrolled manner.

10. Scuppers and save-alls on board are effectively plugged and drip trays are in
position and empty.

Where applicable, all scuppers on board should be properly plugged during the
operations. Accumulation of water should be drained off periodically.

accordance with OCIMF recommendations, where applicable. In the absence of
fixed containment, portable drip trays should be used.
All drip trays should be emptied in an appropriate manner whenever necessary
but always after completion of the specific operation.
ึ
When only corrosive liquids or refrigerated gases are being handled, the
scuppers may be kept open, provided that an ample supply of water is available
at all times in the vicinity of the manifolds.

11. Temporarily removed scupper plugs will be constantly monitored.
Scuppers that are temporarily unplugged, in order to drain clean rainwater from
the cargo deck for example, must be constantly and closely monitored. The
scupper must be re-sealed immediately in the event of a deck oil spill or any
other incident that has the potential to cause pollution.

12. Shore spill containment and sumps are correctly managed.

Shore containment facilities, such as bund walls, drip trays and sump tanks,
should be properly maintained, having been sized for an appropriate
containment volume following a realistic risk assessment.
Jetty manifolds should ideally be provided with fixed drip trays; in their absence,
portable drip trays should be used.

Spill or slop transfer facilities should be well maintained and, if not an automatic
system, should be readily available to deal with spilled product or rainwater.

13. The ship’s unused cargo and bunker connections are properly secured with
blank flanges fully bolted.
See Question 14 below.

14. The terminal’s unused cargo and bunker connections are properly secured
with blank flanges fully bolted.

Unused cargo and bunker connections should be closed and blanked. Blank
flanges should be fully bolted and other types of fittings, if used, properly
secured.
