Regulatory Requirements

Application to be submitted to the PSA one year prior to end of design life.

Clearly defining the extension period Include operators documentation of:

- Check of physical as-is condition and updating of drawings and analysis models accordingly

- Collection of world-wide experience of ageing related incidents and accidents on similar facilities.

- Ageing check, identification of: ageing hazard, chain of events, barriers in these chain of events, failure modes of barriers, simultaneous failure of barriers etc., and indicators (KPI) for monitoring these barriers

- Updating of integrity management plan and maintenance programmetaking into account ageing processes.

PSA activities on Ageing and Life Extension

Initiatives and activities Ageing and life extension identified as a

separate topic in PSA (NPD)regulation in 2002

Joint safety notice on ageing rigs from HSE and PSA (2003)

PSA announced ageing and life extension as a key priority in 2005.

Ongoing dialogue and co-operation with HSE, including exchange of technical and operational information.

Joint HSE/PSA stakeholder events. Research and development programme on

ageing and life extension.

PTIL/PSA

Main activities in the PSA

Audits of operators on how they are handling ageing and life extension R&D to better understand aspects of ageing that may reduce safety of

facilities.- SINTEF, Cranfield University / Ocean Structures, Aalborg University, etc

Co-operation with the operators association (OLF) to develop standards and guidelines for life extension.

Development of database with information on installation date, design life and other issues concerning life extension for facilities in Norwegian petroleum activities.

Development of internal procedures and check-lists for consideration of life extension applications.

Participation in and organisation of workshops, conferences, meeting etc. to inform about issues related to ageing and life extension.

Collaboration with relevant authorities (NMD, HSE, MMS, SodM, etc.).

PTIL/PSA

Norwegian petroleum Industry initiative

From OLF presentation of their own programme

PTIL/PSA

Background

Technical and operational integrity ofoffshore facilities on the NorwegianContinental Shelf (NCS) is importantfor:

the safety, health and welfare of offshore employees and their families

not harming the environment

making sure that the owners get no interruption of their revenues, nor do the government and the citizens of the country

PTIL/PSA

Scope of work

Work divided in two: Firstly to develop and issue recommended

guidelines, outlining a proposal for the preparation of the application of a new consent;

Then to develop tools necessary to assess continued safe operation. Split in the following areas:

Risk management Working environment Structural integrity Technical safety systems Drilling & well systems Topside process & utility systems Transport systems (pipelines etc.) Subsea systems

Process Systems

Consent Applications for Life Extension of Facilities are submitted to the Petroleum Safety Authority (PSA) Norway and Norwegian Petroleum Directorate (NPD).

OLF concluded:The guidelines, standards and checklists developed through this project will provide valuable assistance to offshore facility owners and authorities when assessing the condition of aging facilities, and if they can be safely operated for a new consent period.

Findings from Norwegian ageing programme

PTIL/PSA

Findings from the programme

Clear improvement in the quality of applications. Increased awareness of ageing (senior management,

technical personnel, inspection and maintenance personnel).

Standards and guidelines for life extension have been developed.

Regulation updated on several issues related to ageing and life extension (e.g. testing of parts from decommissioned facilities).

Improvements have been seen in long term maintenance plans for ageing facilities.

PTIL/PSA

Areas where PSA will have continued focus Analyses of what may go wrong when facility is getting

older, and how can we prepare for that (KPIs, trends, increased IMR). HAZOP with ageing keywords (?).

Historical data on integrity of fields. Long term plans for integrity management and taking the

necessary actions needed for keeping the facility sufficiently safe.

Closing the gap between original design and present standard.

Critical components not available for inspections.

PTIL/PSA

Summary

Norwegian industry initiative essential for the programme PSA findings from Ageing Programme:

- Awareness of ageing! Operating and maintaining an ageing facility is different from operating a facility in its design life

- Ageing is more than material degradation- Long term plans are needed

An extensive amount of R&D work has been performed by PSA and OLF. Reports are available from PSAs web-site (www.psa.no).
