EXAMPLES of SECE’s
PERFORMANCE STANDARD of SECE’s
Instrumented Protection System (SIL rated)
– Trip setting of initiating element (e.g. 85% of set pressure relief valve)
– Right sequence of events (shutdown schedule)
– Fail safe
Shutdown Valve (upstream design pressure)
– Closing Time < ... seconds
– Leak Rate < ... m3 /hr
Pressure Relief Valve (set pressure to protect design)
– Opening Pressure > 110% Set Pressure (safety)
– Opening Pressure < 90% Set Pressure (environment)<

1st Party Assurance – Technical Authorities, Review and Audits
Hardware Barrier Assessment- HBA
Technical Authority team visits site and verifies effectiveness of hardware barriers
Each year several sites per Asset according to multi year plan
Close feedback loop: Which HBA-groups are effective and where are improvements required
(strategies; PM-routines; competence; ...).
Outcome HBA is input for PSR evidence at Asset level.
Process Safety Review - PSR
Technical Safety lead review to verify Asset at HSE case level.
Builds on findings of HBA’s, with focus on:
– Management of Changes: Ops Conditions; Hardware; legislation; LFI’s; Procedures; Technology and Organization
– Safety studies (e.g. HAZOP)
– ALARP statement
Operation Excellence Reviews
Integrity Assurance Sustain Review
Maintenance Execution Sustain Review
Operation Integrity Reviews

1st Party Assurance - Strengths and Points of Attention
Strengths Points of Attention
Close to the business and linked withproduction and maintenance processes
Requires up-to-date standards andaccepted methodologies and processes
Integration of design, construction & producephase allows direct feedback andoptimization
Requires sufficient in-house capabilityand competences which are formallyassessed
Allows pro-active approach to anticipatefuture changes (operating conditions,modifications)
Needs special attention to keep up todate with legal requirements, standardsand technology developments
Gives higher efficiency and st imulates “pro-active” behaviour
Appropriate level of independence mustbe ensured
Stimulates ownership and cross learningbetween different assets and operations
Needs right leadership and behaviours ofboth asset line and Technical Authorities
Formal escalation to Shell EVP level (aboveVP NAM NL and OneGas UK)
Might be perceived as less independentby the community at large

2nd Party Inspection – Accredited Internal Inspection Body
For Pressure Equipment an accredited 2nd or 3rd party inspectionbody is required to meet NL legislation of pressure equipment
– Pressure Vessels
– Heat Exchangers
– Storage Tanks
– Piping Systems
– Relief Systems
IQS (Inspection Quality System) is part of CMS(Corporate Management System)
Competency of inspectors are based on external certification
Shell Risk Based Inspection methodology is externally accepted
Inspection Department is formally accredited (Raad van Accreditatie) andappointed by the Dutch Authorities (Ministry of Social Affairs)

2nd Party Inspection - Strengths and Points of Attention -
Strengths Points of Attention
Accredited 2nd party Inspection Body isaccepted alternative over 3rd party InspectionBody satisfy legal requirements for pressureequipment in NL
Needs to maintain an externallyaccredited “quality management system”and organisation
Builds on strengths, knowledge andexperience of 1st party assurance
Needs to maintain certified SKKcompetence levels of inspectors in NL
Seen as more independent than 1st partyassurance by community at large
Inspection techniques and sample sizedepend on full understanding ofdegradation modes/ rates and defectmorphology.Shell Risk Based Inspection methodologyis formally, externally accepted in NL.

Role of 3rd Party Verification – Bureau Veritas
2*
Copyright o+ .oyal /utch Shell plc %th !&'(G ) *r# o+ ,uly 201-
3rd Party Verification - In OneGas UK by Bureau Veritas
In UK the Verification and Examination Scheme of the Duty Holder is requiredby the Offshore Installations Regulations (“Safety Case” and “Prevention of Fire and
Explosion and Emergency Response”)
The Verification and Examination Scheme is compiled by the Duty Holder inconsultation with the Verifier (Independent Competent Person, ICP)
The sampling is risk based aimed at all SCE groups. SCEs are ranked in termsof criticality and drives number of verifications and offshore visits. The criticalityis based on risk (consequence and likelihood of failure)
Verification and Examination comprises witnessing and checking. All findings are recorded in database (BV-net)
Findings are reported as Low, Medium or High priority.
– For OneGas West approx. 100 findings/year (80% Low; 20% medium; no highfindings in past 5 years).
Escalation (none received for OneGas UK in past 5 years):
– “Note of Concern”, when too many findings or insufficient follow-up
– “Note of Reservation”, when “Note of Concern” not satisfactorily resolved.
~3.5 man years to execute the operational (~2.5) and modifications (~1)verifications for OneGas UK

3rd party verification - Strengths and Points of Attention
Strengths Points of Attention
3rd party perceived as more independentthan 1st party and/or 2nd party
More distant from primary businessprocesses (e.g. projects, production andmaintenance) and as such reactive
Verification Scheme/ sampling is risk basedand agreed with Independent CompetentPerson
Independent Competent Person needs tobe competent to verify variety of SCEgroups in project and/or operate phase
Commercial interest of 3rd party verifier
could hamper cross learning betweenverifiers
When 1st party assurance functions properlythis could result in duplication of effort
Copyright o+ .oyal /utch Shell plc %th !&'(G ) *r# o+ ,uly 201-
3rd Party versus 2nd Party: Examples / Considerations
2nd Party Inspection of Pressure Equipment
– Corrosion and degradation rate depends on material selection, medium(CO2, H2S, acidity, salt, sand, ...), temperatures, flow regime, ...
– Heavily integrated with the primary production processes
– Business impact (shutdown duration and frequency)
3rd Party Inspection of Electric Systems – Less integrated with the primary process of exploring and producing
hydro carbons
– Mature and widely accepted industry practices

Independent Verification to prevent Major Accident
First party independent verification supplemented with reviews andaudits does provides the assurance required by the RDS board of itsrespective duty holders
In case additional verification is deemed necessary (e.g. in eye ofpublic) it would be most effective to focus on the primary barriers thatprevent high energy release top events potentially leading to MajorAccident scenario’s. Like:
– Pressure Containment
– Pressure vessels, Pipelines, ...
– Shutdown systems, Emergency Shutdown valves, Pressure Relieve valves, ...
– Structural Integrity
– Primary structure
At present member states impose different requirements
– “Inspection” NL: In depth on selected equipment - Pressure vessels; Life extension Primary
Structure; Cranes; Electric Installation; ....
– “Verification” UK: Risk based covering all SECE’s

Concluding Remarks
The FOUNDATION is a solid Asset Integrity and Process Safetymanagement process, with:
– proactive Leadership
– Competent Staff
– independent Technical Autorities
Reviews and Audits (internal and external) assess the effectivenessof business processes, operational controls and management controlsin ensuring compliance with processes, controls and external laws andregulations
Goal setting, Risk Based and Tiered approach for inspection andverification
