- Applicant to contact OREDA Steering Committee (SC) Chairman to present company profile, operating activities and ability to collect reliability- and maintenance data
- OREDA project manager to check applicant’s relevance, type and quality of reliability data
- Applicant to agree with OREDA SC conditions for Late Participation
- OREDA SC to accept applicant as new member company and sign membership contract
OREDA has collected data in various project phases since beginning of the eighties. Data from each phase are contained in a database that the participating companies have access to. Non-OREDA members may get access to this database when doing contract work for any of these member companies (see name of contact persons on the OREDA Website/Participants).
Additionally, data have been issued in generic form in Reliability Handbooks. Six handbooks have been issued since 1984, the last edition (no. 6) in 2015. For further information on how to purchase a handbook check the OREDA Website/Shop.
Information on equipment performance during normal operation. Basically the following type of information is collected:
- Equipment and operational characteristics (one record for each equipment unit)
- Failure data (one record for each failure)
- Maintenance data (one record for each maintenance task, both corrective and preventive maintenance)
The OREDA taxonomy and specification is contained in a Guideline book which is a project internal document. The OREDA concept has, however, been used as basis for the development of ISO standard no. 14 224 “Petroleum, petrochemical and natural gas industries – Collection and exchange of reliability and maintenance data for equipment” that was issued in December 2006 (2nd edition).
OREDA has focused on offshore topside and subsea equipment but has lately also collected data on some onshore E & P equipment.
Each company has the responsibility to collect the data by using own resources or some data collection contractor. The data collection is planned and co-ordinated by the project manager. Comprehensive guidelines and software tools for this data collection have been developed. A specialised software for more automated data collection has been developed.
Reliability data are used for analysis within the following areas.
Availability, reliability, maintenance, risk estimation, spare part and maintenance manpower calculations, and benchmarking.
A comprehensive software package has been developed for the storing, handling and analysis of the data. This software includes many features for checking of the quality of the data. New equipment classes and taxonomies can easily be included via a separate configuration module. In addition to extensive browsing and searching facilities, the most common type of reliability analysis are included.
The software has been continuously improved and not made available for public sale. For info on current status contact the project manager.
No, the OREDA Handbooks are only available for purchase as regular books.
EQUIPMENT CATEGORIES COVERED IN OREDA HANDBOOK
Table 2 shows the equipment population that has been included in the 2015 handbooks. As focus in later OREDA phases (VI–IX) has been on collecting subsea data, there are some topside equipment classes for which the amount of new data is quite limited compared to previous phases. To obtain a reasonable population for presenting reliability data for topside equipment in the 2015 edition, some data issued in the previous 2009 handbook have been included (see Table 2). For topside equipment, where no reliability data have been collected in phases VIII and IX, the 2015 edition corresponds to the 2009 edition (only true for control logic units). Most of the equipment derives from offshore facilities, but some equipment units from onshore E&P have also been included.
Note 1: The numbers in this column relate to unique equipment units. This is not equal to the sum of units in each phase, since units may have data collected across several phases.
Note 2: Only gas turbine data from phase IX collected according to ISO 14224 are included. Gas turbine data from older phases (i.e. phase VIII and VI) are too dissimilar to be integrated with phase IX data.
Note 3: Steam Turbines and Battery and UPS were not featured in the previous 2009 handbook.
Note 4: Valves are described in two different ways, i.e. by application code (4.4) and by taxonomy code (4.5).
Note 5: Valve data from phase IX collected according to ISO 14224 are not included. Valve data from older phases (i.e. phase VI–VIII) are too dissimilar to be integrated with phase IX data. The data from the older phases far outweighs the data from phase IX, so the older phases are retained for this handbook.
Note 6: Subsea data are not registered in phases the same way as topside data. All subsea data in the OREDA database up to and including 2007 are included, corresponding roughly to data phases up to and including phase IX.
OREDA is a project organisation with eight oil companies as members. Any oil company that operates offshore and/or onshore E & P installations can become an OREDA member. The basic contribution is (1) reliability data and (2) common project funding.
New members are expected to pay a Late Participant (LP) fee to get access to previous collected data, software and other project results. The LP fee is decided by the Steering Committee and will normally consist of both data and cash. Additionally, the member companies pay a yearly fee for common project activities. Further, each member company is expected to contribute with reliability and maintenance data from their operations. The data should have a minimum quality as to informative value.
