AbstractMunitions and explosives of concern (MEC) in U.S. waters can present a risk to the development and operation of offshore wind energy resources. Therefore, the U.S. Bureau of Ocean Energy Management requires offshore wind energy developers to evaluate the risk MEC poses to the development, operation, and maintenance of offshore wind energy generation and transmission systems. This article describes an MEC risk management framework consisting of the following steps: (1) MEC hazard assessment, (2) MEC risk assessment, (3) MEC risk validation, and (4) MEC risk mitigation. The MEC hazard assessment involves historical research to identify MEC potentially present in the development area. The MEC risk assessment evaluates the development activities and provides a relative MEC risk ranking for those activities. The developer determines the acceptability of these risks, and any potentially unacceptable MEC risks undergo risk validation through field surveys. The developer then considers the tolerability of the validated risks and develops and implements an appropriate MEC risk mitigation strategy based on actual site conditions. A risk framework provides a structured method to plan and operationalize the identification, evaluation, and mitigation of MEC risk throughout the development, operation, and maintenance life cycle of an offshore wind energy generation and transmission project.

Literature relating to offshore wind energy generation is produced at a significant rate as research efforts are diverted to the emerging area of future clean energy. This paper presents an overview of recent research in the specific area of floating offshore structure design for wind energy. Earlier literature has broadly grouped these platforms into three categories based on their source of stability: (1) ballast stabilized (low center of gravity), e.g., spar, (2) mooring stabilized, e.g., tension leg platform, and (3) buoyancy or water-plane stabilized, e.g., semisubmersible. These concepts were modifications of similar structures used in the offshore oil and gas industry. Recent papers have presented further improvements to these designs, including active ballasting and control systems. These are examined for stability and global performance behavior and ease of operability and maintenance. The paper also attempts to examine efforts to bring such concepts to fruition. This paper sets the stage for other papers in the Special Session on University of Maine/DeepCWind Consortium within the Offshore Renewable Energy Symposium at OMAE 2012, which are archived in the special section of the Journal of Offshore Mechanics and Arctic Engineering.

Literature relating to offshore wind energy generation is produced at a significant rate, as research efforts are diverted to the emerging area of future clean energy. This paper presents an overview of recent research in the specific area of floating offshore structure design for wind energy. Earlier literature has broadly grouped these platforms into three categories based on their source of stability: - Ballast stabilized (low center of gravity), e.g. spar - Mooring stabilized, e.g. Tension Leg Platform - Buoyancy or water-plane stabilized, e.g. semi-submersible. These concepts were modifications of similar structures used in the offshore oil and gas industry. Recent papers have presented further improvements to these designs including active ballasting and control systems. These are examined for stability and global performance behavior and ease of operability and maintenance. The paper also attempts to examine efforts to bring such concepts to fruition. Combined with this, the authors highlight activities that are ongoing in a consortium of industry and research institutions that is headed by the University of Maine. The origin of such a consortium is explained with reference to the future wind energy potential offshore Maine. This paper sets the stage for other papers in the Special Session on UMaine/ DeepCWind Consortium within the Offshore Renewable Energy Symposium at OMAE 2012.


Subject Offshore wind costs and potential. Significance The International Energy Agency (IEA) released a report on October 25 estimating that offshore wind capacity will rise 15-fold over the next two decades. Costs have been falling ahead of expectations and further cost reductions will help the sector to build more momentum. Impacts North European turbine producers and wind project developers see huge export potential, but Chinese firms will provide stiff competition. Offshore construction vessels will support rising offshore wind deployment and help to bolster currently weak shipyard order books. Governments and regulators will create supportive policies for offshore wind, but this will occur gradually and differently across regions.
