Safety is No Harm - Goal Zero - within Shell
Work with a valid work
permit when required
Conduct gas tests when required
Verify isolation before work
begins and use the specified life
protecting equipment
Obtain authorisation
before entering a confined
space
Obtain authorisation
before overriding or disabling safety critical equipment
Protect yourself against a fall

Do not walk under a
suspended load
Do not smoke outside
designated smoking areas
No alcohol or drugs while working or
driving
Wear your seat belt
While driving, do not use your phone and do not exceed
speed limits
Follow prescribed Journey
Management Plan
5
Managing Process SafetyBow-Ties are used for:
• the identification and risk assessment of HSE hazards
• the evaluation and implementation of control and recovery measures and
• to document that major HSE risks have been reduced to as low as reasonably practicable (ALARP).

The linkages between the other work processes is also very important!!
*RRM is a Shell trade mark: Risk & Reliability Management ; ME: maintenance execution; TA: turn around; EI: equipment integrity; ESP: ensure safe production

Shell RBI has a strict definition
Is a risk-based decision support process
structured and multidisciplinary
to determine and document, cost-effectively,
The optimum inspection requirements
of pressure containing equipment in its operating context
and safeguards integrity

Deliverables S-RBI
Corrosion Control Document per Unit
— Corrosion loops (systems)
– potential degradation mechanismpotential degradation mechanism
– integrity operating parameters
– RBI study validity window
Summary S-RBI analyses
— Criticality distribution
– Focus on critical equipment and piping
– Optimised Inspection Interval
– Summary of equipment with intervals < TA interval
– High level inspection plan
– Follow-up actions and recommendations
Shared knowledge and buy-in by stakeholders
Auditable process (transparency)12

Implementation experience [1/2]
Study based on present knowledge and experience
• Evergreen RBI in the run and maintain phase
• Progressing insights – failure (degradation) modes – during
– inspections and turnarounds
– failure and incident investigations
• Need for knowledgeable team members and shared i f h i d ( d d d d )experience from the industry (standards and procedures)
13
Implementation experience [2/2]
Actions and recommendations
• Interaction with other work processes, i.e EI, ME, TA,Interaction with other work processes, i.e EI, ME, TA, ESP, MOC…..
Competence of RBI facilitators
• RBI knowledge (i.e. API 580, CEN)
• Facilitation skills
• Project management skills
• Methodology skills

How can CEOC play a role?
Inspection and certification bodies
• Standardisation and guidelines
• Certification
– knowledge (i.e. API 580, CEN etc.)
– facilitation skills
– project management skills
