7.6.1Review and Improvement (HSE Cases)

The Design HSE Case may need to go through several revisions during the Define and Execute phases depending on the nature of the design of the new project.

The Operations HSE Case shall be reviewed and updated at a maximum interval of 5 years unless any of the following circumstances occur:

As part of a Material Change to the Facility, operation or surrounding environment that may have a potential impact on the risk profile

When it cannot be verified that the performance of safety critical elements (SCEs) meet the performance standards and/or when mitigation measures have been employed for extended periods to compensate for this shortfall

Prior to any material changes to the organisational arrangements or personnel levels

Following a major incident involving the Facility or operation, or from lateral learning from other major incidents applicable to the Facility or operation

Enhancements in knowledge or technology that change the basic assumptions on which the risk tolerability and ALARP demonstrations are based

If there is a change to any of the signatory parties for the HSE Case, i.e. HSE Case Owner (Director), HSE Case Custodian (Delivery Team Leader) or HSE Case Administrator (Technical Safety Engineer)

7.6.2Material Change

Examples of direct effects are:

1. 
   Significant modifications or repairs to the plant or equipment, either as single large modifications or multiple smaller modifications.
   
2. 
   an increase in hydrocarbon inventory,
   
3. 
   new technology, processes or operational complexity,
   
4. 
   new types of combined operations, or new activities in connection with an installation,
   
5. 
   new operational risk controls.
   

1. 
   new ownership or operatorship, introducing a change in the management system,
   
2. 
   a major change of contractor, and
   
3. 
   extension of the use of the installation or its components beyond the original design life.
   

8ASSET INTEGRITY - PROCESS SAFETY MANAGEMENT

Assuring the safety of people, assets, the environment and reputation is a core value and providing assurance that major process safety risks are being managed is a critical aspect of PDO corporate governance. Asset Integrity – Process Safety Management (AI-PSM) describes the way in which PDO assets are managed so that the process risk is as low as reasonably practicable (ALARP).

There are two Process Safety implementation mechanisms within PDO:

1. 
   The Process Safety Manual of the Shell Group HSSE Control Framework [Ref. 6]
   
2. 
   AI-PSM as developed by Centre for Chemical Process Safety Guidelines for Risk Based Process Safety (CCPS RBPS) [Ref. 9].
   

8.1Process Safety Manual, HSSE Control Framework, Section

The HSSE & SP Control Framework replaces the mandatory requirements in EP2005 series, and includes mandatory Standards, Manuals, Specifications and Glossary terms, and non-mandatory Assurance Protocols and Guides.

The Process Safety Manual of the HSSE & SP CF comprises four elements:

1. 
   Asset Integrity – Process Safety Management Application Manual
   
2. 
   Design and Engineering Manual 1 (DEM1)
   
3. 
   Design and Engineering Manual 2 (DEM2)
   
4. 
   Override of Safeguarding Systems.
   

A full description of each element can be obtained in The HSSE & SP Control Framework [Ref. 6]

Compliance to the detailed requirements of the Process Safety Manual is demonstrated by signing a Statement of Fitness (SoF). The Statement of Fitness is shown in section 12 and testifies that the hazards have been appropriately managed in accordance with HEMP and that a suitable and robust ALARP demonstration has been made.

The Statement of Fitness is a requirement of the AI-PSM Application Manual and a signed SoF shall be included in Design and in Operations HSE Cases, respectively.

For operational assets the SoF shall be signed by Asset Directors, and for new projects by the Project Manager before handover to operations.

8.2Centre for Chemical Process Safety Guidelines for Risk Based Process Safety (CCPS RBPS)

The CCPS RBPS AI-PSM process is an assurance process containing 20 elements ¹that describe minimum expected standards and stipulates the requirements for a range of process related activities ranging from organisational culture, workforce involvement, risk management, HEMP and audit through to design.

The assurance process includes routine checking, self-assessments and audits, as well as independent 3rd party verification that the AI-PSM system and practices are consistent with industry best practice and are controlling process risk to ALARP.

The assurance process also identifies opportunities for improving the management and control of process risk and therefore, is a key driver for continuous improvement.

HEMP is an integral element of the AI-PSM process and the HSE Case and provides a clear link between the two processes. Both the AI-PSM and HSE Case processes aim to identify, control and reduce risk levels to ALARP.
