Inspection of Aboveground Storage Tank

Design Review

  • Main body, foundation of hazmat tank, safety of base rock tank, their seismic design and compliance to applicable standards and regulations are examined and evaluated with design drawing by the specialists in the engineering fields.
  • To install an outdoor tank storage with capacity of 500,000 liters or more and base rock tank, the design review report of KFI must be attached to the application for installation to the fire station authority of the area.

Safety Performance

Outdoor Tanks

The outdoor tanks storing hazmat must be inspected for safety prior to the storage. KFI is conducting the inspections on the ground and weldment, and full-water test of outdoor tanks with capacity of 1 million liters or more. Tanks less than million liters can be inspected by fire station, tank tested, or KFI with full-water test.

Base Rock Tanks

The base rock tanks used to store crude oil, etc., underground are investigated for their bearing capacity, hydrographic conditions, and dimensional changes of the cave during excavation work, to secure safety.

Periodic Inspection

KFI is conducting the inspections on the outdoor tanks with capacity of 1 million liters or more (specific outdoor tank storage) to check safety during use. The test items include evenness and verticality measurement, thickness measurement, NDT and appearance inspection. Regular inspections (structural safety inspection) shall be conducted by the facility operator and KFI provides sampling test services.

Regular Inspection Period:
  • Period before 12 years from the date of issuance of the construction completion inspection certificate.
  • Period before 11 years from the last regular inspection.

Completion Inspection

Completion Inspections are conducted at completion of installation or change of position, structure or installation, to verify compliance to the engineering standard specified in the Hazardous Materials Safety Management Act.
