Temporary Refuge (TR) door only Visual inspection of valves & live systems only Dropped object management No inspection/maintenance on hydrocarbon systems No inspection/maintenance on hydrocarbon systems Double Block & Bleed (DB&B) isolations/valves for breaking containment during Final Cleaning & P&A. Inspection per standard/frequency agreed with DECC/ General Visual Inspection (GVI) to manage dropped object risk. Controls only (metering not required) Temporary Refuge (TR) / Battery room heaters only Use rig lifting equipment General Visual Inspection (GVI) to manage dropped object risk. General visual Inspection (GVI) to monitor physical condition General visual Inspection (GVI) to monitor physical condition Utilise AWV navigational aids For AWV-platform access ramp General visual Inspection (GVI) to monitor physical condition Low frequency GVI inspections, based on reduced risk. Low frequency GVI & UT only (if flow/pipe-lines de-pressurised), based Low frequency ROV-based GVI & Cathodic Protection (CP) inspections only (if flow/pipe-lines de-pressurised) on based reduced on reduced risk. risk. Inspection per standard/frequency agreed with DECC/ Reduced inspection/maintenance requirement if de-pressurised Valves for pipe-line degassing Reduced inspection/maintenance requirement if de-pressurised Reduced inspection/maintenance on HC systems if depressurised Reduced inspection/maintenance on HC systems if depressurised Use AWV lifting equipment Cold Suspension Marker Buoys Marker buoys or lift-boat NavAids Inspection per standard/frequency agreed with regulators (AAA/BBB) Inspection per standard/frequency agreed with regulators (AAA/BBB) For fire & gas systems & communications Until buoys are installed, or NUI is in Cold Suspension Vendor will supply temporary launcher / receivers Includes escape-to-sea section of spider deck For ongoing operations purposes (e.g. fuel bunkering) Maintenance Operations & Maintenance framework 3 OP111
