Failure Investigation

Ensuring equipment failures are understood, lessons learnt and future designs optimised

​

Subsea equipment failure and replacement is extremely costly, especially if production is affected. Failure investigations help capture lessons learnt, define corrective actions, prevent recurrence of problems and save future operational costs.

We undertake root cause failure analyses for all types of subsea equipment and offer a range of specialised investigation services in-house and through a network of laboratories and universities; including:

​

• External and internal visual inspection, including borescope if required

• Equipment dissection

• Material characterisation

• Mechanical properties testing

• Micro-analysis

Project Examples

Root Cause Failure Analysis

An RCFA was conducted on a failed subsea component. The work included:

​

• Test program design

• Visual inspection (internal and external)

• Leak path testing

• Chemical and microstructure analysis

• Fractographic examination

• Total hydrogen content testing

• Hardness profiling

• Corrosion resistance testing

• Tensile testing

• Dye penetrant investigation

• Reporting
