[1] Data from phase V issued in the 2002 handbook have been included in the population of this handbook. For equipment where no new data have been collected since the 2002 issue, data from phase IV and phase V previously issued in the 2002 issue have been included. Since the 2002 issue some changes in the equipment population for phase IV and V data has been made due to additional new data, removal of outdated equipment etc.

Note that the above table only lists the contents of handbooks and not the database. The database also contains data for phases VIII and IX. The complete OREDA databases are currently available for the member oil companies only or contractors/persons working on their behalf.

The first OREDA Handbook with reliability data was published in 1984. These data were collected by manual means only and not included in the later computerised database. Subsequently four more Handbooks have been published (1992, 1997, 2002 and 2009). The latest Handbook with phase VI and VII data was issued in December 2009.

OREDA has provided a sound basis for boosting reliability technology and collecting and exchanging reliability data through the establishment of common standards and references for reliability information, development of guidelines and software for data collection and analysis and publication of reliability data and knowhow. Two examples reported by the participating oil companies refer to total savings of $70 millions for alternative designs in comparison with the original designs. Similar savings have also been reported by other companies. Reliability data were not the only basis on which the decisions were made, but they did provide better grounds for selecting a good design.

The OREDA concept has been developed as an ISO standard (ISO 14 224). It was published in December 2006 (2. edition) and can be purchased from the ISO organisation. The title of this Standard is: "Petroleum, petrochemical and natural gas industries – Collection and exchange of reliability and maintenance data for equipment".
