RELIABILITY ENGINEERING
RELIABILITY STRATEGY
Teledyne-ODI uses a multi-pronged strategy to reliability engineering that focuses on reliability planning, engineering analysis and verification through life testing and field data. This customer focused approach focuses on
Elimination of costly failures during deployment and during use.
-
Assure and demonstrate that the required reliability has been achieved.
-
Continuous improvement in the reliability and availability of products.
RELIABILITY BY DESIGN
Reliability begins at the conception of the design; Teledyne-ODI’s reliability engineering processes are fully integrated into the product development process to realize the reliability goals. This is achieved through a three step process of careful reliability planning, flawless execution and verification through reliability testing.
To achieve and exceed the customer’s stringent reliability requirements, the following tools are integrated into the development process.
 Failure Modes , Effects and Criticality Analysis (FMECA’s)
Fault Tree Analysis / Root Cause Analysis. (FTA/RCA)
Reliability Block Diagram Analysis (RBDA)
Failure Reporting , Analysis and Corrective Actions (FRACAS)
Accelerated Life Testing and Environmental Stress Screening (ALT/ESS)
Design for Reliability, with the help of the above tools, focuses on selecting the appropriate materials, redundancy in designs and elimination of single point failures. Extensive qualification and reliability testing assures that the required reliability has been achieved.
Design For Reliability
RELIABILITY BY EXCELLENCE IN FIELD PERFORMANCE
Teledyne-ODI follows a systematic approach to assuring the customers of the field reliability of its products. Reliability and Availability data are compiled and analyzed to provide the most useful and relevant data to the customer. By combining reliability engineering through design techniques with reliability assurance through appropriate metrics, reliability engineering remains at the core of the entire product life cycle. This principle is illustrated in the following bath-tub curve.
Attacking the Bathtub Curve
The superior field record of ODI products is a testament to Teledyne-ODI’s excellence in design and process reliability. Teledyne also takes utmost care to ensure the integrity of the field performance data. The process of reliability data collection and analysis is based on international standards such as ISO 14224 and industry best practices. The ODI reliability data pyramid shown below illustrates the different levels of the process.

RELIABILITY BY TESTING
Teledyne-ODI employs extensive testing of
products including accelerated life testing to
improve the long-term reliability of its
designs. Qualification of the products includes
testing to verify common industry
standards. The suite of tests used by ODI
include:
-
Life Cycle Mate-Demate
Testing
-
Accelerated Life Testing
-
Highly Accelerated Life
Testing
-
Mechanical shock and
Vibration
-
Thermal shock testing
-
Hydrostatic Pressure and
Cycle Testing
-
Environmental Stress
Screening
-
Multi-Stress Composite
Testing
-
AC/DC voltage
qualification
-
Hose Pull Test to Failure
-
Material Testing
Hose Test to Failure
Test results are carefully analyzed
and documented through test reports. Periodic
re-qualification of designs ensures compliance to
changing requirements in the sub-sea industry.
The testing program is carefully planned with
consideration to compliance to international
standards such as ISO 13628 and industry
standards such as
NHT-I52-00073 ,
GS EP SPS 021 etc.
RELIABILITY BY
RESEARCH & TRAINING
Teledyne-ODI believes in investing in training
and research in reliability engineering. With
Certified Reliability Engineers (CRE) on staff ,
the entire design team is trained on
cutting-edge reliability tools and techniques.
The engineering teams are also focused on
reliability research projects for developing
better testing methods, evaluating reliability
of new materials etc. The following links
provide a variety of technical papers related to
reliability presented to leading conferences and
technical exchange meetings:
