OGC Level 1 Training Handbook-RU v1

It also does not address the issue of how to calculated the quantity of such an adjustment. It is entirely possible for the shipper and receiver to agree on making a pipeline adjustment and for the terminal to refuse. If we know this in advance, we can alert the shipper and receiver before the fact and not after the fact when it is so much harder to do anything about it. It is our policy to not adjust custody transfer quantities based upon line fullness verification unless we are advised in writing by all interested parties. To keep our clients informed on this issue, we should use one of the following clauses in our order confirmation, or other suitable means if the client does not want order confirmations: "Please be advised that we have contacted the XYZ Terminal where your vessel is to load /discharge, to confirm the requirement for a line fullness verification. The terminal has advised us that this verification will not be permitted. On behalf of our principals, we will issue a LOP/ NOAD to the terminal; however, we would ask you to further clarify this with the terminal, (contact Mr./ Ms. ABC, at Tel / Email.) and any principal who is sharing the cost of the inspection and advise us your instructions." or "Please be advised that local practice, for the XYZ Terminal where your vessel is scheduled to load/discharge, is to use the:

 line packing,  line displacement,  line circulation,  pigging, or  high-point bleed valve method to conduct line fullness verification. We will monitor and report the results of the line fullness verification; however, API MPMS Chapter 17.6 does not provide for quantity adjustments, therefore, we do not adjust custody transfer quantities based upon line fullness verification unless we are advised in writing by all interested parties."
