Oil and gas offshore facilities structures operating in harsh environments are associated with high risk and the likelihood of failures. Hence, frequent inspections are needed to enhance the integrity and reliability of these 'platforms' structures using a rigorous strategy. The purpose of this research is to develop an integrity management strategy for an above and underwater offshore platform steel structure using risk-based integrity management assessment. This strategy is developed in four steps: step one identifies the elements of the platform structures suitable for risk-based integrity management; in step two, identifies anomalies and degradation mechanisms. The third step is hazard identification using qualitative risk analysis, by hazard and operability model, and quantitative risk analysis, by the fault tree model, to calculate the probability of failure then qualitative assessment assigns the consequences. Step four ranks the risk to prioritize inspection and maintenance schedule and build an integrity management strategy. As an outcome of this thesis, we are able to identify and categorize the degradation and deterioration mechanisms for the fixed steel structure platforms and gain an understanding of platform structural risks and rank these according to severity. Consequently, increase and enhance the reliability and integrity of the platform using an appropriate integrity management strategy. The proposed risk-based integrity management analysis proved that the risk-based inspection and risk-based maintenance methods used in this work are effective in terms of time, efficiency and cost, through reducing the frequency of inspection from 12 months to 24 or 36 months in some cases.

Oil and gas assets are under constant pressure and engineers and managers need integrity management training and strategies to ensure their operations are safe. Gaining practical guidance is not trained ahead of time and learned on the job. Asset Integrity Management of Offshore and Onshore Structures delivers a critical training tool for engineers to prepare and mitigate safety risk. Starting with a transitional introductory chapter, the reference dives into integrity management approaches including codes and standards. Inspection, assessment, and repair methods are covered for offshore, FPSO, onshore and pipelines. Suggested proactive approaches and modeling risk-based inspection are also included. Supported with case studies, detailed discussions, and practical applications, Asset Integrity Management of Offshore and Onshore Structures gives oil and gas managers a reference to extend asset life, reduce costs, and minimalize impact to personnel and environment. - Bridge between the theory of integrity management into oil and gas application - Understand the strategies and techniques to mitigate corrosion affect, assessment, inspection, and repairs from real-world examples - Manage a variety of assets including offshore, subsea, pipelines, and onshore

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: 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.

API RP 2SIM, 1st Edition, November 2014 - Structural Integrity Management of Fixed Offshore Structures. This recommended practice provides guidance for the structural integrity management (SIM) of existing fixed offshore structures used for the drilling, development, production, and storage of hydrocarbons in offshore areas. However, the general principles of SIM apply to any structure. Specific guidance is provided for the evaluation of structural damage, above- and below-water structural inspection, fitness-for-purpose assessment, risk reduction, mitigation planning, and the process of decommissioning. This recommended practice incorporates and expands on the recommendations of Section 14, "Surveys" and Section 17, "Assessment of Existing Platforms" as previously provided in API 2A-WSD, 21st Edition. See Annex A for additional information and guidelines on the provisions stated in the numbered sections of this document. The SIM process provided in this recommended practice is applicable to existing platforms installed at any location worldwide. However, the recommended practice provides specific metocean criteria, which are only applicable for use in fitness-for-purpose assessments of platforms located in the U.S. Gulf of Mexico and the U.S. West Coast. For guidelines, recommended practices, and other requirements relating to planning, designing, and constructing new fixed offshore platforms, including reuse and change-in-use of existing platforms, reference should be made to the latest edition of API 2A-WSD. For guidelines, recommended practices, and other requirements relating to planning, designing, and constructing new offshore floating production systems, including reuse and change-in-use of existing floating production systems, reference should be made to the latest edition of API 2FPS.

This book examines the fire-resistant design of fixed offshore platforms. It describes the required loading, load combinations, strength and stability checks for structural elements. It also explains the design of tubular joints, fatigue analysis, dynamic analysis, and impact analysis, Fire resistance, fire, explosion and blast effect analysis, fire protection materials, and safety.

Offshore Risk Assessment was the first book to deal with quantified risk assessment (QRA) as applied specifically to offshore installations and operations. Risk assessment techniques have been used for more than three decades in the offshore oil and gas industry, and their use is set to expand increasingly as the industry moves into new areas and faces new challenges in older regions. This updated and expanded third edition has been informed by a major R&D program on offshore risk assessment in Norway and summarizes research from 2006 to the present day. Rooted with a thorough discussion of risk metrics and risk analysis methodology, subsequent chapters are devoted to analytical approaches to escalation, escape, evacuation and rescue analysis of safety and emergency systems. Separate chapters analyze the main hazards of offshore structures: fire, explosion, collision, and falling objects as well as structural and marine hazards. Risk mitigation and control are discussed, as well as an illustration of how the results from quantitative risk assessment studies should be presented. The third second edition has a stronger focus on the use of risk assessment techniques in the operation of offshore installations. Also decommissioning of installations is covered. Not only does Offshore Risk Assessment describe the state of the art of QRA, it also identifies weaknesses and areas that need further development. This new edition also illustrates applications or quantitative risk analysis methodology to offshore petroleum applications. A comprehensive reference for academics and students of marine/offshore risk assessment and management, the book should also be owned by professionals in the industry, contractors, suppliers, consultants and regulatory authorities.
