Book Description
This report discusses research conducted to investigate and develop hydrographic survey equipment for objective, detailed, and quantitative definition of the underwater shape of coastal structures. The research included development of and investigation of the Coastal Structure Acoustic Raster Scanner (CSARS) system. Although much information was gained from CSARS development, the capabilities of commercially available multibeam systems like the SeaBat 9001 multibeam sonar system surpassed the still prototype CSARS. Therefore, this investigation concentrated on multibeam sonar systems, and field demonstrations and trials were conducted with the SeaBat system. The SeaBat system was successful in providing accurate, high resolution hydrographic data on the underwater condition of various structures. With multibeam sonar systems, it is now possible to have types of survey information that were previously impractical to obtain or were unattainable, leading to safer, more cost effective management of coastal structures over their lifetimes.

Book Description
UNDERWATER INSPECTION AND REPAIR FOR OFFSHORE STRUCTURES Benefit from a much-needed, up-to-date handbook on underwater inspection and repair processes and technologies Underwater Inspection and Repair for Offshore Structures fills a gap in the literature to provide an overview of the inspection and repair processes for both steel and concrete offshore structures. Authors and noted experts on the topic John V. Sharp and Gerhard Esdal guide readers through the reasons why inspection and repair are performed and how both are linked to the management of structural integrity, statutory requirements, and various types of damage. The book addresses critical topics, including the execution and planning of inspection and repair, the tools and methods used, and their deployment underwater. The authors put particular focus on steel and concrete offshore oil and gas installations, but the content is also applicable to the substructures of offshore wind turbines. Underwater Inspection and Repair for Offshore Structures is complementary to the authors’ book Ageing and Life Extension of Offshore Structures, also from Wiley. This important book: Covers current inspection and monitoring techniques to evaluate existing structures Includes coverage of robotic (ROV) inspection and repair methods Provides an overview of repair and maintenance techniques applicable to the splash‑zone and underwater operations Written for engineers, designers, and safety auditors working with offshore structures. Underwater Inspection and Repair for Offshore Structures is a comprehensive resource for understanding how to effectively inspect and repair these vulnerable structures.

Book Description
A general introduction to side scan sonar (SSS) and its uses in coastal engineering studies is given, including some operating rules-of-thumb and suggestions based on the author's experience. There is also a section evaluating several systems currently on the market. SSS is a valuable tool for coastal engineering, with uses likely to multiply as the technology and our experience with it improve. However, quantitative applications are limited. Information on structure slopes, condition of individual armor units, and percent of units displaced (to name a few examples) is not currently measurable in a repeatable, quantitative way. Nevertheless, the semiquantitative sonograph record can be very informative, particularly to someone who has developed a familiarity with the structure or feature being viewed from repeated SSS surveys. It is a safer, and in many cases, superior alternative to visual inspection by divers, especially in murky water. Keywords: Coastal structure inspection; REMR(Repair, Evaluation, Maintenance, and Rehabilitation); Side scan sonar; Underwater inspection. (jhd).

Book Description
Inspection is crucial to the management of ageing infrastructure. Visual information on structures is regularly collected but very little work exists on its organised and quantitative analysis, even though image processing can significantly enhance these inspection processes and transfer real financial and safety benefits to the managers, owners and users. Additionally, new opportunities exist in the fast evolving sectors of wind and wave energy to add value to image-based inspection techniques. This book is a first for structural engineers and inspectors who wish to harness the full potential of cameras as an inspection tool. It is particularly directed to the inspection of offshore and marine structures and the application of image-based methods in underwater inspections. It outlines a set of best practice guidelines for obtaining imagery, then the fundamentals of image processing are covered along with several image processing techniques which can be used to assess multiple damage forms: crack detection, corrosion detection, and depth analysis of marine growth on offshore structures. The book provides benchmark performance measures for these techniques under various visibility conditions using an image repository which will help inspectors to envisage the effectiveness of the techniques when applied. MATLAB® scripts and access to the underwater image repository are included so readers can run these techniques themselves. Practising engineers and managers of infrastructure assets are guided in image processing based inspection. Researchers can use this book as a primer, and it also suits advanced graduate courses in infrastructure management or on applied image processing.
