A comprehensive overview of managing and assessing safety and functionality of ageing offshore structures and pipelinesA significant proportion, estimated at over 50%, of the worldwide infrastructure of offshore structures and pipelines is in a life extension phase and is vulnerable to ageing processes. This book captures the central elements of the management of ageing offshore structures and pipelines in the life extension phase. The book gives an overview of: the relevant ageing processes and hazards; how ageing processes are managed through the life cycle, including an overview of structural integrity management; how an engineer should go about assessing a structure that is to be operated beyond its original design life, and how ageing can be mitigated for safe and effective continued operation.Key Features: Provides an understanding of ageing processes and how these can be mitigated.Applies engineering methods to ensure that existing structures can be operated longer rather than decommissioned unduly prematurely.Helps engineers performing these tasks in both evaluating the existing structures and maintaining ageing structures in a safe manner.The book gives an updated summary of current practice and research on the topic of the management of ageing structures and pipelines in the life extension phase but also meets the needs of structural engineering students and practicing offshore and structural engineers in oil & gas and engineering companies. In addition, it should be of value to regulators of the offshore industry.

UNDERWATER INSPECTION AND REPAIR FOR OFFSHORE STRUCTURES Benefit from a much-needed, up-to-date handbook on underwater inspection and repair processes and technologiesUnderwater 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 structuresIncludes coverage of robotic (ROV) inspection and repair methodsProvides an overview of repair and maintenance techniques applicable to the splash‑zone and underwater operationsWritten 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.

'Materials Engineering' delves into strengthening reinforced concrete members and dynamic properties of carbon fiber-reinforced polymers. 'Building Materials and Concrete Structures' cover topics like minibar reinforced concrete, impact response of reinforced columns, and residual strength of cement-based composites.
