3. THE FUEL EVENT COMPLEXES
In the following a short description is given of the key issues within each complex together with the resulting consequences.
Starting from an entry-situation a decision path with simple yes/no decisions inevitably leads to consequences of which the degree of probability is indicated by the position of the event box, starting with a high probability at the left. Where consequences have an impact on later event scenarios this is marked in the bottom line boxes.

3.1 The OEM Fuel Specification
It is important to check which fuel quality the OEM specifies in the handbook supplied with the engine. For engines built recently this will certainly be a category of ISO 8217: 1996. For engines built before 1996 the probability will be significant that something else is specified. Which normally cannot be guaranteed by fuel suppliers who these days are organized to supply fuels according to ISO 8217 : 1996 and hardly anything else.
The shipowner, therefore, in his own interest should ensure that the information given in the engine manual is updated to the latest edition of ISO 8217, without amendments and cuts.
Recently discussed individual specifications "at the engine" are of little value when ordering supply. The supplier cannot assess the efficiency of the fuel treatment system on board of his client's vessel.
It is the author's belief that in spite of a few deficiencies ISO 8217: 1996 is the most unambiguous marine fuel specification. Asking for anything else can result in players of the supply chain drawing benefit from deficiencies of earlier specifications.
