The inspection and cleaning interval can vary based on the type of tank. For example, above ground storage tank shall be inspected at a minimum every 5 years according to API-653 Section 6.

Cleaning and repairs should be addressed based on the findings of the tank inspection. Additional inspections between maintenance intervals are encouraged.

Drone's are used as a tool to reduce exposure to employees of hazardous environments or working conditions. It's a very cost effective means of avoiding costly scaffolding and other craft support.

A visual inspection is exactly what it sounds like: a careful, thorough review with the naked eye of every single part of an asset.

In many instances, a drone inspection will be a visual inspection, with the drone’s camera acting as the inspector’s eyes. Using a drone, visual data is collected and then reviewed in detail later by the inspector (some review is done on the spot, too, but the thorough inspection after data is collected represents the bulk of the visual inspection work).

RBI categorizes or risk ranks your equipment from low to high based on the relation between the probability and consequence of failure. The results of an RBI study are detailed damage mechanism analysis, inspection planning, and overall mechanical integrity program optimization. An effective RBI study will focus your facilities budgetary dollars on the high-risk assets first, often extending inspection intervals of lower-risk assets.

Mechanical Integrity (MI) is the management of process equipment such as pressure vessels, storage tanks, pressure relief devices, and piping systems. It is one of fourteen elements of OSHA’s Process Safety Management (PSM) standard. An adequate MI program will guarantee that all equipment is designed and installed per applicable codes, procedures, and specifications. MI also ensures that equipment is installed, operated, inspected, and maintained in a safe, environmentally friendly, and reliable manor.

NDE/NDT is the testing or evaluation of a material that does not cause damage during the testing process. Some examples are thickness testing of steel, flaw detection of tubes or rods, weld inspection using ultrasonics or Xray, etc. NDE/NDT is used in a multitude of industries across a large variety of material types. Compared to part/material repair or replacement NDE/NDT can be a very cost-effective way of determining the material mechanical integrity.

There are many complexities for determining what inspection code governs your tank inspections. Many tanks will have a data plate that give you the code of construction. From there you can determine which inspection code governs tanks built to that code. For instance, tanks built in accordance with API 650 will require an inspection in outlined in API 653.

Corrosion under insulation (CUI) is exactly what it says it is. It is corrosion that develop underneath insulation under equipment, tanks, and piping. Overtime, insulation gets damaged, worn, or punctured. These areas of damage allow moisture ingress which can cause accelerated corrosion cells to form. On equipment or piping that is coated, this process can be slowed but ultimately failure can still occur. InServe has developed CUI programs that can help you prioritize your CUI inspections and optimize your budget by identifying and focusing on high risk equipment.

Pressure Vessels are containers which are designed to hold liquids, vapors, or gases at high pressures, usually above 15 psig. Examples of common pressure vessels used in the petroleum refining and chemical processing industries include, but are not limited to, storage tanks, boilers, and heat exchangers. Each individual vessel has its own operating limits built in by design that it has to work under, referred to as its design pressure and design temperature. Operating outside of these limits could damage the equipment and potentially lead to loss of containment or catastrophic failure.

A Storage Tank is a container for storage of water, oil, gas and petrochemical products for domestic and industrial uses. Storage tanks are available in many shapes and sizes. They can be vertical, horizontal, underground and portable, and can be made from plastic, steel, fiberglass, stone or concrete. Water tank leakage and corrosion, as well as bacterial growth, are threats to the tank.
