9 Subsea Materials Database Program Proprietary materials database developed through collaboration with Teledyne Scientific Common and new subsea materials tested at accelerated levels in multiple fluids. Data is available to Teledyne Marine engineers to use during design work. Database includes single and multi-stress testing. 9

12 Data Collection and Analysis Data collected on every unit returned since Longer for some product lines. System in place for capturing reported but nonreturned units. analysis performed on a yearly basis for all data gathered the previous year. Performed using Exponential and Weibull distributions. Used to update predictions and look for trends. FMECAs are updated at the same time. 12
