Every atmospheric storage tank in serious service lives on the API 653 cycle: periodic external inspections in service, and internal inspections when the tank comes out of service and opens. For coating and lining decisions, the internal inspection is the moment of truth, and preparing for it beats reacting to it.
What the inspection finds
Floor scan and shell examination reveal where the lining has protected and where it has not: holidays that let product and water reach steel, disbondment at the floor to shell weld, pitting under failed patches. The report converts directly into scope: spot repair, floor reline, or full internal recoat.
The decision logic on linings
Scattered minor findings with a sound lining elsewhere point to patch repairs with compatible material. Widespread disbondment or a lining past its service life points to full removal, blast to ISO 8501-1 Sa 2.5 and a new system, solvent free epoxy for fuels and crude, phenolic where the cargo demands it. Half measures over a failing lining waste the outage; the next inspection finds the same problem grown.
Externals ride the same outage
Shell and roof external systems, insulation and CUI checks on heated tanks, and structural fireproofing all share the scaffolding and access of the internal work. Bundling them into one outage is the cheapest coating campaign a terminal ever runs.
Prepare materials before the tank opens
Lining systems, repair kits, abrasives and test equipment on site before entry means findings convert to work without waiting on procurement. With Fujairah and Jebel Ali tankage on continuous inspection cycles, UAE demand for lining materials is steady and predictable.
