A S S E T I N T EG R I T Y

• Asset Integrity – The ability of an asset to carry out it’s designed function in an effective and efficient manner across it’s operational life mitigating harmful effects that can compromise safety, the environmental and health effects.

• 51% of Oil and Gas installations are at least 20 years old.

• 58% seen a fall in asset integrity standards due to the fall in the Oil price.

• 63% of Oil and Gas professionals seeing pressure to reduce asset downtime over last 12 months.

• Effective Integrity Management provides the

following benefits:

• Economical

• Safety

• Reputational

• Environmental

• Effectively managing and applying it can ultimately prevent catastrophic events.
