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.
