Repair, Evaluation, Maintenance, and Rehabilitation Research Program. Procedures and Devices for Underwater Cleaning of Civil Works Structures

Abstract

Civil works structures must be continually evaluated for structural safety, stability and operational adequacy. Proper inspection and evaluation of them to identify deficiencies will usually require some type of cleaning of the structure. A wide variety of underwater cleaning tools and methodologies have been developed and are currently in use in the offshore oil industry and by the US Navy. These tools range from hand-held scrapers to powered tools and high- pressure waterjets. Several tools have been specifically designed for removal of underwater debris. These tools include jet eductors, dredges, and air lifts. This report summaries underwater cleaning procedures and devices that are appropriate for use on civil works structures. The application, advantages, disadvantages, and operation of each type of equipment are discussed, along with recommendations for those tools best suited for specific conditions.
