To ensure a thorough inspection, the area must be cleared of all marine growth. This can be done by various means, depending on surface support. A high-pressure water jet is the most effective method for clearing marine growth sufficiently for visual inspection. Hand tools, such as wire brushes and scrapers are sufficient for smaller jobs.
