Overview:

The testing outlined in this publication is intended to provide risk management information for use

in the assessment of new additives prior to their actual use in a pipeline. It describes the minimum information required from suppliers and shippers of additive-containing products in multi-product pipeline systems that co-transport jet fuel. It is intended to demonstrate to pipeline operators and other interested parties that these products will not subsequently adversely affect jet fuel, or have an adverse effect on pipeline operations as part of an ordered management of change process.

This publication is intended for use internationally by pipeline operators, fuel suppliers and additive companies involved in fuel supply through multi-product pipelines where jet fuel is co-transported with other distillate fuels, gasoline grades and clean fuel components.

The key changes included in this fourth edition are:

  • An update to the new procedure involving assessment of the impact on filter/water separator water removal performance of a candidate additive. This ‘water mapping screening’ provides a risk-managed approach to assessing additive suitability by reference to known additive impact on EI 1581 Specification and qualification procedures for aviation jet fuel filter/separators, filter/water separator performance.
  • Clarification that ‘water mapping screening’ is recommended but not mandatory if a pipeline trial (which is optional) has been undertaken.
  • Clarification that the scope is limited to surfactant additives only.

A list of additives that pipeline operators have confirmed to the EI have been assessed in accordance with the requirements of this publication, or its previous editions, and with which they have experience of satisfactory use in their pipeline operations, can be found here  EI 1535 Additive Listing.
