Savings using Robotic Tank Inspection

Save Money, Save Time

Robotic Tank Inspection Savings

Robotic tank inspection saves our customers time and money, while meeting or exceeding the API 653 and EPA SPCC requirements. Providing refineries and tank farm owner’s a safe and efficient nondestructive testing (NDT) inspection for large hydrocarbon storage tanks. Our ground breaking robotic inspection technology uses ultrasonic sensors to inspect the floor including the critical zone, which provides an accurate tank floor plate condition assessment, with limited or no downtime.

Manta Robotics’ Nautilus floor inspection robot saves the tank owner an estimated 68% over the expensive cost of emptying and cleaning the tank, loss of revenue from downtime, and the expensive cost of hazardous waste disposal.

Manta Robotics’ Nautilus floor inspection robot is NFPA Certified purged and pressurized method, and complies with the API 653 Section 6.4.1.2 as an approved method for Above-ground Tank Storage (ATS) inspection methods. The Nautilus floor inspection robot collects thousands of data point and provides an accurate map of the tank floor condition. Manta’s in-tank inspection process takes days, rather than weeks, and putting you in control of your day-to-day operations and scheduling.

Inspection Comparison Breakdown

Out-of-service inspection:

  • Removing the tank from service
    • Typically 3 to 4 weeks.
    • The impacts of removing the tank from service is facility dependent.
  • Displacing the fuel
    • Moving the fuel to another location.
      • Option 1: Use trucks/rail cars to move fuel to another tank.
      • Option 2: Consume and replace the fuel.
    • Some facilities have the ability to move fuel to other tanks.
  • Preparing the tank.
    • Steam cleaning and degassing.
    • Sludge removal and disposal.
    • Cutting and welding the tank for entry.
  • Performing the inspection.
    • Once prepared and the tank made safe for human entry, the actual inspection will go very quickly.  Dependent upon size this would be 2 to 4 days.

Robotic inspection:

  • Removing the tank from service.
    • Not necessary.
    • If desired the tank can be valved out.  This may be desirable if noise from pumps needs to be reduced or the need to keep the same level of fuel in the tank is needed.
  • Displacing the fuel.
    • Not applicable.
  • Preparing the tank.
    • Dependent upon the construction of the tank.  A platform may need to be constructed on the top of the tank to stage equipment.
  • Performing the inspection.
    • Dependent upon size this would be 2 to 4 days.
