Offshore Reliability Data Handbook 5th Edition, Volume 1 – Topside Equipment, Volume 2 – Subsea Equipment (OREDA 2009)

A necessary publication for modern offshore engineering!

The handbook contains OREDA® Phase VI (2000-2001) and Phase VII (2002-2003) data, including topside and subsea equipment.

The OREDA-02 is sold out.

The OREDA handbook is prepared by SINTEF Technology and Society on the behalf of the OREDA project and sold by DNV.



Introduction

The 5th edition of the OREDA Handbook was released in December 2009 containing OREDA® Phase VI (2000-2001) and Phase VII (2002-2003) data. Reliability data collected and processed in the OREDA® project has been published in generic form in four Reliability Data Handbooks; 1984 (1st edition), 1992 (2nd edition), 1997 (3rd edition) and in 2002 (4th edition). The Handbooks contain reliability data on offshore equipment compiled in a form that can easily be used for various safety, reliability and maintenance analyses. The 2009 edition of the OREDA Handbook include data from phase VI and VII of the OREDA project, and covers the period 2000 - 2003. The data are compiled in a similar manner as the former Handbooks, and include data on a similar detailed level as the '02 handbook, typically for use in maintenance analyses (e.g. RCM).

Application

The OREDA 2009 handbook will give you a unique data source on failure rates, failure mode distribution and repair times for equipment used in the offshore industry. Such data are necessary for reliability as well as risk analyses.

·         SUBSEA EQUIPMENT
Control Systems

What is new in the OREDA 2009 handbook?

The 2009 edition covers some additional equipment units than in the '02 edition. Additionally the following equipment classes are included:

Similar as in the OREDA-02 handbook we have included the following information:

This information is valuable when conducting a Failure Mode and Effect Analysis (FMEA). The FMEA analysis is further a major part of a reliability centered maintenance (RCM) analysis.

Maintainable Item versus Failure Mode

In OREDA each equipment class (e.g. compressors) is broken down in a three-level hierarchy:

Maintainable item/level is defined as 'an item that contribute a part, or an assembly of parts, that is normally the lowest indenture level during maintenance'. In the Maintainable Item versus Failure Mode table the relative (percentage) contribution from each maintainable item to the total failure rate is given in total and related to the failure modes.

Failure Mechanism versus Failure Mode

In the OREDA database a "failure mechanism"-field is available. The information in this field describes the apparent or observed failure cause. In the Failure mechanism versus Failure Mode table the relative (percentage) contribution from each failure cause to the total failure rate is given; in sum and related to the failure modes.
