Visual Inspection is the oldest and most basic method of inspection. It is the process of looking over a piece of equipment using the naked eye to look for flaws. It requires no equipment except the naked eye of a trained inspector.
Visual inspection can be used for internal and external surface inspection of a variety of equipment types, including storage tanks, pressure vessels, piping, and other equipment.
Visual inspection is simple and less technologically advanced compared to other methods. Despite this, it still has several advantages over more high-tech methods. Compared to other methods, it is far more cost effective. This is because there is no equipment that is required to perform it. For similar reasons it also one of the easiest inspection techniques to perform. It is also one of the most reliable techniques. A well-trained inspector can detect most signs of damage.

Nondestructive Testing (NDT) makes up the majority of testing performed in our industry. There many different types of nondestructive testing techniques. Each method has its own advantages and disadvantages; each can detect different types of flaws. Some are simple to perform, others are difficult. Some are used on several different types of equipment, others are more restricted.
Industrial Rope Access is a proven method of achieving a safe work position at elevated heights or areas that are difficult to access. When combined with advanced NDE technologies, rope access technicians can substantially reduce the cost of inspections and maintenance activities by virtually eliminating the need for fixed scaffolding.

To understand the current non-destructive testing (NDT) world, it is perhaps a good idea to look back at things historically. By doing this, changes which have taken place become apparent, and very soon one can conclude that this is actually quite significant!
