What is Ageing? RR509 (2006)RR509 (2006)

The management of equipment begins with an awareness that ageing is not about how old the equipment is, but what is known about its condition, and the factors that influence the onset, evolution and thence mitigation of its degradation. O h f i d d d d d f Once the symptoms of ageing are understood, and detected from inspection, a decision can be made how to proceed. The options can include putting together a case to justify continued service, re-rating, repair, or scrapping the equipment.repair, or scrapping the equipment.

There are also managerial issues that should also be considered. The company culture and defined roles and responsibilities are important in relation to managing equipment. g g q p

Ageing management is also affected by staff demographics, skills, training and competencies.

Keeping documentary information and records throughout equipment life Keeping documentary information and records throughout equipment life is important.

IMPROVEMENTS OFFSHORE

BUT..

Existing work loads are very high meaning Existing work loads are very high, meaning taking time out to consider ALE issues is difficult.

Fabric maintenance still a challenge, with id d CUIwidespread concerns over CUI.

Need for better appreciation of Ageing and planning for Life Extension, and day-to-day p g y ymanagement - further integration into mainstream asset management

Auditing and verification needs to be improved ud t g a d e cat o eeds to be p o edfor ALE

Work will be needed to implement industry good ALE practicesALE practices.

Offshore environment will remain a challenge.

However, is ageing/life extension a h lth d f t i l h ?health and safety issue elsewhere?

Ageing plant management remains a significant challenge for process industriesp

But what about non-major hazard jsites?

Current economic environment means everyone Current economic environment means everyone has to squeeze their assets, with inevitable life extension:

lets put off that car park maintenance until let s put off that car park maintenance until the lease runs out

that boiler will run for another couple of winters wont it?winters, won t it?

do you really mean that lifting strop is too old surely we can still use it

we cant afford to replace that database we can t afford to replace that database cant we keep on running the old system?

now you tell me the ventilation plant cant cope with the new production line!cope with the new production line!
