It would appear that not all oil companies are aware of the changes to the COW Manual as revised in 2000, particularly with regard to the fact that this revision does not contain a list of unsuitable crude oils for COW. INTERTANKO had brought this issue to IMO and demonstrated that the list in the previous COW Manual appeared to be inadequate guidance for COW suitability determination.

Whilst we will be bringing this to the attention of the oil companies as well, for good order members should take note of the following:

The COW Manual, as revised by IMO and published in 2000, has a completely new Section 9 - "Determination of the suitability of a crude oil for the use in crude oil washing". This Section does not contain the list of unsuitable crude oils for COW but has replaced the old list with new parameters for determining suitability.

For a copy of the new Section 9 of the IMO COW Manual link to.
