Før OREDA prosjektet begynte å samle data eksisterte det «ingen offentlig kilde av feilinformasjon for offshore installasjoner», risikovurderinger ble dermed basert på «generisk data fra onshore petroleumsinstallasjoner og data fra andre industrier».<ref name=Leroy>{{cite journal|last1=Leroy|first1=A.|editor1-last=Wingender|editor1-first=Hans Jörg|title=Status of the OREDA Project|journal=Reliability Data Collection and Use in Risk and Availability Assessment: Proceedings of the 5th EuReDatA Conference|date=9.–11. april 1986|pages=38-46|url=http://link.springer.com/chapter/10.1007%2F978-3-642-82773-0_4|publisher=EuReDatA|location=Heidelberg, Germany|accessdate=11. september 2015|quote=Despite the considerable interest in risk and reliability engineering studies for offshore systems, no authenticated source of failure information existed for offshore installations, before 1985.
