Storage Tank Inspections

Objectives of Tank Inspections

The importance of Tank Inspection and condition monitoring is unquestionable in:

• avoiding failures
• maintaining safety
• optimising availability

Facilities with tanks often present additional risks beyond site risks such as

• Potential injury to site personnel
• Damage to equipment and lost business
• Tanks are often located in areas of environmental value
• The encroachment of suburbia, are close to the community.
• Legal issues and reputation damage. 

A good tank inspection program is designed to:

• Show that tanks are not leaking and will not leak before next inspection
• Reduce the potential for un-planned releases
• Maintain tanks in safe operating condition
• Make repairs as required and have them tested to comply with standards and regulatory requirements
• Determine if and when replacement is necessary.
