External Inspection Items / G / F / P / N/A / Comments
Insulation: Verify sealed around manways, nozzles, no damage present, and there is no egress of moisture. / X / Vessel is Insulated on external building portion.
External Condition: Assess paint condition, areas peeling, record any corrosion, damage, etc (record location, size and depth of corrosion or damage) / X / Paint in good condition – no exposed metal.
Leakage: Record any leakage at flanges, threaded joints, weep holes on repads, etc. / X / No leaks detected.
Skirt: Assess condition of paint, fire protection, concrete. Look for corrosion, buckling, dents, etc. Look at vessel surface area near supports. Verify no signs of leakage at attachment to vessel and attachment welds are acceptable. Ground wire attached? / X / No distortion to saddles – no missing paint – no leaks at shell to saddle welds.
Skid Package is grounded.
Anchor Bolts: Hammer tap to ensure secure. Look for cracking in treads or signs of deformation. / X / Firmly bolted to skid deck.
Concrete foundation: Check for cracks, spalling, etc. / X
Ladder / Platform: Describe general condition, ensure support is secure to vessel, describe any hazards. / X
Nozzle: Assess paint, look for leakage, and ensure stud threads are fully engaged. Record any damage, deflection, etc. Are nozzles gusseted? / X / Good condition, no deflection, no leaking detected.
Studs fully engaged to nuts.
No gussets.
Gauges: Ensure gauges are visible, working, no leakage, and suitable for range of MAWP/ Temp. / X / Pressure gauge: 0 to 2000 psi
Temperature gauge: 50 to 300 deg F
External Piping: Ensure pipe is well supported. All clamps, supports, shoes, etc. in place. Look for evidence of structural overload, deflection, etc. Paint condition, external corrosion? / X / Firmly supported, no deflection, no loose or missing clamps.
Paint in good condition, no corrosion.
Valving: Ensure no leaks are visible. Valves are properly supported and chained if necessary. / X / Valves are well supported with no leaks present.
PSV: Ensure PSV is set at pressure at or below that of vessel. / Located on top shellset below MAWP of vessel.
Seal intact – no block valve – discharge piping same size as outlet orifice.

NDE methods: Was UT/ MPI done on vessel

(MI coordinator to review results) / X / Ultrasonic thickness survey carried out in 2007 – pipingmetal thickness detected below nominal minus corrosion allowance. Calculations carried out to ensure sufficient metal exists for safe operation.
Recommendations or corrective actions : Vessel is Fit for Service or describe corrective actions required)
(MIC to review corrective actions with Operations, discuss with Chief Inspector where necessary, and get remedial action implemented)
Recommendations: No recommendations at this time – return vessel to service.
Summary: This vessel is in good condition, ultrasonic corrosion survey carried out– piping metal thickness detected below nominal minus corrosion allowance. Calculations carried out to ensure sufficient metal exists for safe operation.
Vessel is fit for service.

Internal Inspection Items / G / F / P / N/A / Comments
Coating Assess coating. Describe area coated, general condition of coating. / X / Coating is chipped and deteriorated at the man way neck.
Anodes. How many, type, condition. % consumed. Are they being replaced? / X / No anodes
Internal Piping Is there any? If so, carbon or stainless steel. Describe condition, dents, corrosion, erosion, etc. Ensure supports are secure and any bolts are suitable for future use. / X / No internal piping
Trays How many? Type of material. Are valves in place. Check for erosion/ corrosion; wear on tray valve legs. Cleanliness? / X / No trays.
Baffles, deflector plates, etc. If present, describe condition. Look closely at welds attached to vessel wall. / X / Inlet deflector in place – no broken members – no corrosion to welds. Surge weir in very good condition – no distortion – firmly attached.
South Head Note all corrosion, erosion or mechanical damage. (If vessel is horizontal identify direction of this head) / X / Coating is in very good condition at heads – no chipping or delaminations.
North Head Note all corrosion, erosion or mechanical damage. (If vessel is horizontal identify direction of this head) / X / Coating is in very good condition at heads – no chipping or delaminations.
Shell Sections Record number of shell sections. Record location, size and depth of all erosion, corrosion or mechanical damage. Describe general condition. If any corrosion greater than corrosion allowance is observed in either shell or head, discuss with Chief Inspector before closing vessel. / X / 3 shell sections – Coating is in very good condition at shell sections – no chipping or delaminations.

Demister pad Is it in place? Is it clean? If any corrosion is apparent in vessel, lift pad and check top head for corrosion.

/ X / Intact and in place – no distortion.

Welds Inspect all welds, including attachment welds. Record all service-related damages and if there is any discuss with Chief Inspector before closing.

/ X / Coating is in very good condition at welds – no chipping or delaminations.

Repairs Required. If yes, ensure procedure and copy of AB 40 is on file, and one sent to local ABSA, and Chief Inspector

/ X /
  1. Coating on man way nozzle was repaired prior to closing vessel.

NDE Was any NDE done. ( MI coordinator to review results)

/ X / Visual inspection only – no NDE at this time.
Recommendations or corrective actions : Vessel is Fit for Service or describe corrective actions required)
(MIC to review corrective actions with Operations, discuss with Chief Inspector where necessary, and get remedial action implemented)
Other Observations:
Recommendations: 1. Repair chipped coating at man way neck. (Note – Coating was repaired prior to closing vessel)
Summary: This vessel is in good condition, visual external and internal carried out – internal is coated with epoxy – on small area of exposed metal which was hand patched with epoxy. No previous corrosion.
Vessel is fit for service
