Early Concept & Define Activities
• Safety Layout Review – Topsides
– Early identification of possible ’Major Accident Hazards’, ’Initatiors’ and ’Escalators’ and their relative proximity
– Redistribution of ’, ’Initatiors’ and ’Escalators’ to mitigate ’Major Accident Hazards’
– To build in ’Inherent Safety’
• Concept based Working Environment Impact Assessment
– Early identification of shortcomings in design wrt
– NCS and NORSOK compliance
– “Logistics” for the LQ
– Functionality and interfaces between different functional areas
– Potential space issue related to technical installations
– Significant potential for freeing space (excessive cabin size)
– Paramount to include correct competence, especially Architectural with Offshore Design experience

AoC (SUT) & Operational Case for
Safety • AoC (SUT) submission will enhanced to include the requirements as for an Operational Safety Case
– Scope will be the full field development
• AoC (SUT) will be based on
– OLF 065 – Handbook for Application for AoC
– BG-ST-HSSE-AI-001 – Safety Case Standard
– IADC – HSE Case Guidelines for MODUs
– * With precedence as shown above
• Main difference to the Combined Operational Safety Case and AoC (SUT) are:
– Demonstration of ALARP
– Incorporation of the Working Environment aspects
– Posivite identification of Regulatory Compliance
– Positive identification of Deviations to Regulations
– Formal aceptance of submission by Workers Representative
