Hello, my name is Tao Ni and you can just call me Tao. I am living in Norway right now and I like to travel. I also like running because I enjoy the process of running and feeling of sweating. It is very glad to come this place and please take care of me :)

The Offshore and Onshore Reliability Data (OREDA) project was established in 1981 in cooperation with the Norwegian Petroleum Directorate (now: Petroleum Safety Authority Norway). The initial objective of OREDA was to collect reliability data for safety equipment. The current organization, as a cooperating group of several oil & gas companies, was established in 1983, and at the same time the scope of OREDA was extended to cover reliability data from a wide range of equipment used in oil & gas exploration and production (E&P). Offshore topside and subsea equipment are primarily covered, but some onshore E&P equipment is also included, and data collection is currently being extended for the onshore industry.

The main objective of the OREDA project is to contribute to an improved safety and cost-effectiveness in design and operation of oil & gas E&P facilities, through collection and analysis of maintenance and operational data, establishment of a high quality reliability database, and exchange of reliability, availability, maintenance and safety (RAMS) technology among the participating companies.

Project Phases

Phase I (1983–1985) The purpose of phase I was to collect and compile data from offshore drilling and production operations. The data were published in the OREDA-84 handbook. An objective of the handbook was to demonstrate the ability of the eight participating oil & gas companies to co-operate on this issue and create a forum for a common co-operative process in this field. Data was collected on a wide area of equipment (large population) but not with as much detailed information as in later phases. Data from this phase are not included in the OREDA computerised database. Phase II (1987–1990) The scope was adjusted to only collect data on production critical equipment, to improve the quality of the data, and to store the data in a PC database format. A tailor-made PC program (called the OREDA software) was developed to aid the collection and analysis of the data. The data were published in the OREDA-92 handbook. This handbook also contains the data collected in phase I. Phase III (1990–1992) The number of equipment categories was increased, and more data on maintenance programs were collected. The data quality was improved by means of the comprehensive “Guidelines for Data Collection” and through quality control. The OREDA software was modified into a more general-purpose data collection tool, and its user interface was improved. The data collected in this phase are published in the OREDA-97 handbook. Phase IV (1993–1996) New software for data collection and analysis was developed, plus specific software and procedures for automatic data import and conversion. Data were collected mainly for the same equipment as in phase III, and the data collection was – to a greater extent – carried out by the companies themselves. Data on planned maintenance were included. The data collected in this phase are published in the OREDA-02 handbook. Phase V (1997–2000) Some new equipment classes were included and more focus was given on collecting subsea data. As a parallel activity, the ISO standard 14224: “Petroleum and natural gas industries– Collection and exchange of reliability and maintenance data for equipment” was developed and issued in July 1999. The data collected in this phase are published in the OREDA-02 handbook. Phase VI (2000–2001) Data collection on subsea equipment and new equipment classes were prioritised. A forum for co-operation between major subsea manufacturers was formed. The data collected in this phase are published in the OREDA-09 handbook. Phase VII (2002–2003) Priority was given on safety and subsea equipment. A revision of ISO 14224 was started with important contribution from members of the OREDA project. The data collected in this phase are published in the OREDA-09 handbook. Phase VIII (2004–2005) Phase VIII was essentially a continuation of phase VII. OREDA members were involved in the revision of ISO 14224, issued in December 2006. The data collected in this phase are published in the OREDA-15 handbook. Phase IX (2006–2008) The OREDA taxonomy was adapted to ISO 14224. There was a continued focus on worldwide span of data coverage. An OREDA seminar was held as part of the 25 year anniversary. The data collected in this phase are published in the OREDA-15 handbook.The OREDA project has since continued and is currently (2015) in its 12th phase.

Up-to-date information on the OREDA project is available on the OREDA website: http://www.oreda.com.

Participates

Over the years, there have been some changes among the OREDA participants due to companies exiting, entering or merging to form new companies. However, during phase VIII and IX the membership have been quite stable. Table 1 summarises the companies that have contributed with data in these phases.

Organization

The OREDA project is managed by a Steering Committee with one member and one deputy member from each of the participating oil & gas companies. The Steering Committee elects one of its members as chairman and appoints a Project Manager. The Project Manager co-ordinates the activities approved by the Steering Committee, and also performs data quality assurance. Det Norske Veritas (DNV) served as Project Manager during phases I and II and SINTEF during phases III–IX. From phase X onwards DNV GL is again the Project Manager. The preparation of the OREDA handbooks has been carried out as separate projects in agreement and consultation with the OREDA Steering Committee. The current version has been prepared by SINTEF and NTNU, and is marketed by DNV GL.

Need

The reliability of E&P equipment has a major impact on safety, production availability and maintenance costs. Ensuring high technical integrity is paramount to safe and reliable operations in E&P, particularly offshore. OREDA has collected data to determine the consequences, the causes and the likelihood of such failures. A query among the OREDA companies shows that the need for such data is high. Oil companies are operating today in a very competitive environment. Here, OREDA can help to optimise life cycle cost and reduce maintenance cost through the application of reliability know-how and data. Traditionally the main use of reliability data has been in engineering design studies. Such data have been given increased attention for use also in the operating phase in recent years.

Data

Collected data are stored in a database containing data from 278 installations, 17 000 equipment units with 39 000 failure and 73 000 maintenance records. The databank also includes subsea fields with over 2000 years operating experience. Only the OREDA member companies have access to the computerised database with its comprehensive search and analysis software. Temporary access may be given to contractors working for the OREDA companies.

Database Structure

The data are recorded per owner and installation. Each individual item (e.g. a gas turbine) occu¬pies a single inventory record in the data¬base. This record contains a technical description (e.g. manufacturer information) plus operating and environmental conditions¬¬. For each inventory, all failure events are stored. Each failure event is identified by item name, date of failure, failure impact, failure mode, failure cause etc. The maintenance records contain data on corrective maintenance linked to the corresponding failure record, and data on preventive maintenance linked to the corresponding inventory record.

Software

Purpose made OREDA® software (SW) has been made to handle data collection, acquisition and analysis. Additionally, special utility SW is developed for SW configuration, automated data transfer, quality check etc. The SW concept is flexible and can be configured to user defined applications. The SW includes features for advanced data search and selection, and commonly used reliability analyses. The software is also used to collect internal company data. A tailor made SW has been developed for subsea data. This SW module has a feature used as a tool for logging of events.
