Why Shut down?

We firmly believe that 'shut down' is the least appropriate time to establish the condition of plant 'in service' and arguably the most expensive in terms of direct cost and the financial consequences of unearthing problems when it is too late in the day to procure or implement cost effective corrective action.

We are also convinced that sufficient non-invasive inspection techniques exist to enable the vast majority of condition assessment to be performed in a non-disruptive and pre-emptive fashion whilst plant is on-stream.

In simple terms, we believe that the wrong time to inspect is when its -

• Too late - to effect remedial action
• Too disruptive - with respect to necessary engineering work priorities
• Inadequate time - to assess the condition of critical items
• Wrong conditions - to do this effectively & reliably
• Not cost effective - due to work intensity, priorities & scheduling.

• Those items which can only be inspected by direct access, e.g. tube bundles
• Where access (staging) is facilitated through other work
• When more detailed scrutiny is called for & convenient to perform.

Properly scheduled Risk Based Inspection using NII techniques reduces the frequency, scale and cost impact of shutdown and enables -
