Willacy Oil Services Tank Inspection

The advantages include:

  • No scaffold, no rope access, fully automated Non-Destructive Testing (NDT) method of inspection.
  • No interface between contractors – we can commence inspection of the tank externals while the cleaning is taking place leaving only the floor scan and internal DVI, settlement etc. for when the tank has been cleaned to hot-work standard. This can reduce the tanks downtime.

  • If we are providing both cleaning and inspection, then this eliminates any potential misunderstanding regarding the degree of clean required to conduct the NDT, saving both time and money.
