Definition: The offshore science and engineering inspection has been traditionally based on the regulatory practices of industry; safety and health legislation have been backed up. Two reasons of hazards are leading now the part of industry. They are greater appreciation and experience of increased operation so as to adopt the more educated way for planning the inspection, inspection target was required for the risk reduction as few as practicably reasonable. The equipment type has been determined the frequency of the inspection, examined the locations and employed the methods - with the few consideration which was given to the specific duty, age.

The process which will develop an plan of inspection based on the risk of knowledge for the equipment of failure is called as Risk based inspection. Risk analysis is the necessary element. This is grouping of likelihood assessment (probability) of the failure because of damage, degradation or deterioration with the consequences assessment for such of the failure.
