4.2.4 Associated Safety Cases The safety case will describe the purpose and scope of all other safety cases referenced within the Production Safety Case.
4.2.5 Roles and Identities of Third Party Organisations The roles, identity and safety-related relationship of any third party organisations that have a critical bearing on the management of Major Accident Hazards (and including those operating their own Safety Management Systems) shall be summarised.
As a minimum, details will be required for organisations carrying on the following in respect of the designated petroleum activity
Design and construction of changes
to petroleum infrastructure
Integrity management, or assurance services in respect
of petroleum infrastructure
Drilling and well services and
Operational support where the third party’s day today operations are not under immediate control of the petroleum undertaking. The safety case must identify third parties whose cooperation maybe required
in an emergency situation, or to prevent an emergency situation, who are not under the control of the petroleum undertaking.
In addition, the safety case will outline arrangements for the petroleum undertaking or its workforce to cooperate with a third party in respect of an emergency arising in respect of a petroleum activity being carried on by that third party. These arrangements must be demonstrated in this safety case.
Example If two offshore platforms carrying out production for two different petroleum undertakings are connected by a pipeline such that one exports to the other, the importing platform would need the exporting platform to cease export in the event of an emergency. This maybe achieved by diverse automatic and manual communication means and these should be identified here and described in later sections of the safety case.
