Most companies are postponing their decommissioning activities due to cash flow restrictions, others are taking advantage of low oil prices to speed up decommissioning activities as some of the related oilfield service costs are also reduced.However, decommissioning is an emerging and growing market. Global decommissioning projects are expected to increase from about $2.4 billion per year in 2015 to $13 billion per year by 2040, with approximately 2,000 offshore structures to be decommissioned between 2021 and 2040. Companies are looking for ways to streamline the decommissioning process to reduce overall costs.

This conference series deals with the civil, offshore & environmental engineering field, addressing the following topics: • Environmental and Water Resources Engineering • Coastal and Offshore Engineering • Structures and Materials • Construction and Project Management • Highway, Geotechnical and Transportation Engineering and Geo-informatics This book is an essential reading for academic, engineers and all professionals involved in the area of civil, offshore and environmental engineering.

This book provides a comprehensive overview of the key aspects and contracts involved in the process of developing oil and gas projects, with an emphasis on offshore developments. Project development in oil and gas carries with it numerous unique risks and challenges. By identifying and managing risk through the various contract stages, each stage of the project is seen in perspective and therefore gives readers a better understanding of how that stage was arrived at and what is expected to come later. To do this, the authors use illustrative international case studies from past and current projects, thereby deepening the reader’s understanding and awareness of risk from practical experience, as well as suggesting answers for those who are involved in developing oil and gas projects. The Application of Contracts in Developing Offshore Oil and Gas Projects is intended for project owners, project managers, contractors, finance managers, commercial managers and lawyers who seek to understand the subject from a practical point of view.

Offshore wind energy is one of the most promising and fastest growing alternative energy sources in the world. Offshore Wind Energy Cost Modeling provides a methodological framework to assess installation and decommissioning costs, and using examples from the European experience, provides a broad review of existing processes and systems used in the offshore wind industry. Offshore Wind Energy Cost Modeling provides a step-by-step guide to modeling costs over four sections. These sections cover: ·Background and introductory material, ·Installation processes and vessel requirements, ·Installation cost estimation, and ·Decommissioning methods and cost estimation. This self-contained and detailed treatment of the key principles in offshore wind development is supported throughout by visual aids and data tables. Offshore Wind Energy Cost Modeling is a key resource for anyone interested in the offshore wind industry, particularly those interested in the technical and economic aspects of installation and decommissioning. The book provides a reliable point of reference for industry practitioners and policy makers developing generalizable installation or decommissioning cost estimates.

This study was established to assist with development of a Topic Strategy on Decommissioning of Offshore Installations. The study begins by highlighting the key issues relating to abandonment of offshore installations and identifying knowledge gaps. A review is included of the likely decommissioning schedule for all UK sector North Sea installations together with their classification and the weight and water depth of the largest structures affected by the OSPAR decision. The abandonment process is described as a framework for considering safety management and technical issues related to decommissioning. Previous HSE research is reviewed and new issues are identified as a result of recent experience and the changing regulatory requirements.

This open access book offers a timely guide to challenges and current practices to permanently plug and abandon hydrocarbon wells. With a focus on offshore North Sea, it analyzes the process of plug and abandonment of hydrocarbon wells through the establishment of permanent well barriers. It provides the reader with extensive knowledge on the type of barriers, their functioning and verification. It then discusses plug and abandonment methodologies, analyzing different types of permanent plugging materials. Last, it describes some tests for verifying the integrity and functionality of installed permanent barriers. The book offers a comprehensive reference guide to well plugging and abandonment (P&A) and well integrity testing. The book also presents new technologies that have been proposed to be used in plugging and abandoning of wells, which might be game-changing technologies, but they are still in laboratory or testing level. Given its scope, it addresses students and researchers in both academia and industry. It also provides information for engineers who work in petroleum industry and should be familiarized with P&A of hydrocarbon wells to reduce the time of P&A by considering it during well planning and construction.

"While the energy sector is a primary target of efforts to arrest and reverse the growth of greenhouse gas emissions and lower the carbon footprint of development, it is also expected to be increasingly affected by unavoidable climate consequences from the damage already induced in the biosphere. Energy services and resources, as well as seasonal demand, will be increasingly affected by changing trends, increasing variability, greater extremes and large inter-annual variations in climate parameters in some regions. All evidence suggests that adaptation is not an optional add-on but an essential reckoning on par with other business risks. Existing energy infrastructure, new infrastructure and future planning need to consider emerging climate conditions and impacts on design, construction, operation, and maintenance. Integrated risk-based planning processes will be critical to address the climate change impacts and harmonize actions within and across sectors. Also, awareness, knowledge, and capacity impede mainstreaming of climate adaptation into the energy sector. However, the formal knowledge base is still nascent?information needs are complex and to a certain extent regionally and sector specific. This report provides an up-to-date compendium of what is known about weather variability and projected climate trends and their impacts on energy service provision and demand. It discusses emerging practices and tools for managing these impacts and integrating climate considerations into planning processes and operational practices in an environment of uncertainty. It focuses on energy sector adaptation, rather than mitigation which is not discussed in this report. This report draws largely on available scientific and peer-reviewed literature in the public domain and takes the perspective of the developing world to the extent possible."
