At a recent industry meeting it was agreed that there is a need for some guidance related to the implementation of the latest edition of API/IP 1581.
This Bulletin is valid with immediate effect but the following key dates should be noted:
a) New filter separator vessel purchases shall be specified for 5th edition compliance with immediate effect (see item (1) on page 2 for guidance).
b) Installed 3rd edition coalescer elements can continue in service until replacement is required, due to maximum differential pressure or 3 years, but subject to a final change-out date of June 30, 2008.
c) Purchased stocks of 3rd edition coalescer elements can be used for replacement purposes until June 30, 2006, but subject to a final change-out date of June 30, 2008.
At Joint Venture airport locations, any variation of the above dates requires the approval of the international head offices of the participant companies.
