Underwater Repair Technology

This book provides an overview of the techniques available to the offshore industry for the joining and repair of offshore structures. The last few years have seen many developments in underwater engineering technology where a wide range of welding techniques, and the necessary associated equipment, are now available for underwater joining procedures in the offshore industry.The extraction of hydrocarbons from offshore reserves is now a worldwide industry, with activity on every continent. There are huge steel and concrete structures standing in 200 metres of water, with more innovative designs, such as tethered platforms capable of operating in deeper waters, and with 1000 metre reserves currently being considered. New materials – stainless steels, duplex stainless steels, aluminium, Monel, coated materials, and non-metallic materials such as reinforced plastics are beginning to be used in significant quantities. Joining and inspection techniques have been greatly developed, and new design concepts have been brought into use.Concentrating on repair technology the author presents a survey of the techniques available for the fabrication, repair and modification of structures underwater. His book is an important reference for those working in the international offshore engineering industry, and will also be of value to universities and training establishments offering courses on marine technology.

The book provides an comprehensive overview of the techniques available for the joining and repair of offshore structures. Nixon starts with joining systems that do not require welding and then explores the associated engineering systems needed for joining procedures. Topics include pipe handling, hyperbaric chamber design, and principal underwater welding techniques, including wet, one atmosphere, and hyperbaric. Nixon also includes a description of the effects of environmental pressure on the various hyperbaric welding processes. A complete guide to underwater welding, this book also discusses technologies that show promise in the laboratory, but are not currently in use. Nixon provides appendices describing the relevant diving technologies, basic oceanography, and the research methods used in the development of hyperbaric welding.

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.

First published in 1981 as the Offshore Information Guide this guide to information sources has been hailed internationally as an indispensable handbook for the oil, gas and marine industries.

Concrete will be the key material for Mankind to create the built environment of the next millennium. The requirements of this infrastructure will be both demanding, in terms of technical performance and economy, and yet be greatly varied, from architectural masterpieces to the simplest of utilities.Specialist techniques and materials for concrete construction forms the Proceedings of the three day international conference held during the Congress, creating with concrete, 6-10 September 1999, organised by the Concrete technology unit, University of Dundee.
