A comprehensive overview of managing and assessing safety and functionality of ageing offshore structures and pipelines

A 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:

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.

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:

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.

This book publishes contributions of the 1st Olympiad in Engineering Science (OES 2023), an international congress and contest aiming to disseminate and evaluate the recent advances in Engineering Science. The book is divided in several parts. In ''Materials Science,'' readers delve into nanostructural correlations in thermochromic VO2 thin films for smart windows, as well as microstructural observations of super duplex stainless steel. The ''Marine Technology'' part explores riverbed scour, wave reflection, and innovative nature-based solutions for coastal protection. ''Additive Manufacturing and Welding Technology'' delves into studies on carbon fiber-reinforced polymers and fatigue properties of 3D-printed specimens. ''Structural Integrity and Structural Health Monitoring'' offers insights into offshore pipeline fatigue life prediction and risk-informed decision-making for existing structures. The ''Non-destructive Testing and Evaluation'' part encompasses stress monitoring, rail profile measurement, and health-monitoring approaches for debonding diagnosis. ''Dynamics and Vibrations'' ventures into investigations on combined viscous and Coulomb damped systems and seismic signal analysis for landslides. ''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. ''Electronic Sensors and Intelligent Systems'' showcase simulations under high voltage transmission lines, synthesis of BaxSr(1-x)TiO3, and antenna catheter modeling. ''Asset Integrity'' discusses analytical and experimental analyses of buckling in aluminum columns and I-beams, lateral-torsional buckling capacity, and modulation of fluid streams. Finally, ''Climate Change and Circular Economy'' addresses climate-adaptive design, circular economy integration, and eco-innovative concrete applications with recycled materials. This book provides a comprehensive overview of cutting-edge research and advancements in mechanical and civil engineering, offering valuable insights for researchers, practitioners, and enthusiasts in the field.
