Risk-based Inspection is a type of maintenance business process used to analyze equipment, including pressure vessels, heat exchangers and piping in industrial plants. It is a decision-making technique to optimize inspection plans.

The theory of Risk-based Inspection is built upon the concept that the risk of failure can be assessed in connection with a level that is acceptable, and inspection and repair used to assure that the level of risk is below that acceptance limit.

Led by industry experts, including senior consultants and engineers, DASH's unparalleled Risk-based Inspection programs feature a total quality assurance approach. We employ a comprehensive and structured approach - in line with industry guidelines like API 580, 581 and API 571 - to analyze the potential risks of each asset by evaluating their current operating conditions in terms of the probability and the consequence of failure, providing our clients with a unique view of the condition of each asset.
