1. Presentation School of Science & Engineering MSc Applied Instrumentation & Control MSc I&C, GCAL

2. FPSO * Turret Equipment Room Emergency Shutdown (TER ESD) System Upgrade ( A project for Oil & Gas Platform at North Sea) * Floating Production, Storage and Offloading Presented By Syed Naqvi

6. The Problem MSc I&C, GCAL

11. Partial Expansion MSc I&C, GCAL

16. TER ESD Replacement/Upgrade (3) Installation Space Required MSc I&C, GCAL

18. MSc I&C, GCAL Systems Results Trusted Trusted would be most suitable system in terms of space requirements, obsolescence, fault tolerant and availability. Tricon Tricon can be suitable in terms of installation space but its size would be 2 times larger than Trusted and is less Fault tolerant. PROSAFE- RS Prosafe-RS can be suitable in terms of installation space but its size would be 2 times larger than Trusted. Although it is SIL3 rated and 99.999% availability but have double redundant architecture rather than TMR architecture Aadvance For 50 % capacity Aadvance will occupy than two system bays i.e. requires very large installation space. GMR GMR would occupy around three system bays and it can't be install in TER for 50% capacity.*1 For 20% still the space requirements are huge.

20. Conclusion MSc I&C, GCAL Techniques Recommendations ESD Replacement First choice Partial Expansion Not Recommend Redesign 2oo3 Relay voter logic Not Recommend TER ESD Expansion Not Recommend Safety Systems Recommendations Trusted First Choice Triconex Second Choice Prosafe-RS Third Choice Aadvance Not Recommend GMR Not Recommend
