“…With the U.S. sector of this industry in its infancy, and site conditions differing significantly from established projects in Europe (i.e. Musial and Ram 2010;Sirnivas et al 2014;DOE-DOI 2016;EY Report 2015;Wind Europe 2017), there are multiple potential avenues in which the U.S. research community can advance and streamline observational and modeling components of site characterization efforts.…”

The landscape of applied ocean technology is rapidly changing with forces of innovation emerging from basic ocean science research methodologies as well as onshore high tech sectors. There is a critical need for ocean-related industries to continue to modernize via the adoption of state-of-the-art practices to advance rapidly changing industry objectives, maintain competitiveness, and be careful stewards of the ocean as a common resource. These objectives are of national importance for the dynamic ocean energy sector, and a mechanism by which new and promising technologies can be validated and adopted in an open and benchmarked process is needed. POWER-US seeks to develop Ocean Test Beds as research and development infrastructure capable of driving innovative observations, modeling, and monitoring of the physical, biological, and use characteristics present in offshore wind energy installation areas.The Industry Need: Throughout the second half of the last century, ocean technology advancements ushered in new ocean-related industries and ocean advancements that changed the course of history. Remote and deep water oil and gas exploration and extraction methods, bottom survey methods, global shipping route optimization, ocean storm and weather forecasting, etc. have enabled substantial economic gains. That much of ocean science and engineering today continues to rely on technologies developed in the last century is a testament to the robust nature of our previous development efforts. However, more recent technological innovations in environmental sensing, computing, and automation offer the potential to further revolutionize both existing ocean-related industries such as: energy, mining, transportation and shipping, global trade, adaptation and resiliency, defense and security, salvage, and ocean exploration as well as newly emerging ocean uses.One clear example of the need for rapid adoption of new technology is in the area of offshore wind energy production. As a new energy industry in the U.S., offshore wind shows tremendous potential as a component of the nation's energy future portfolio. However, solid scientific data on the design characteristics as well as consensus on the interactions of a wind farm with the marine environment are critical to reduce risk, advance public acceptance, and evolve the regulatory process. Coupling this with the unique conditions present over the U.S. outer continental shelf in areas slated for development, an acute need exists for creating the physical and organizational infrastructure to rapidly move innovations in site characterization through systematic validation and into industry best practices and/or regulatory requirements. This process requires an open and evolving infrastructure that allows benchmarked data sets to test and evaluate sensors, improved systems modeling, and analysis by neutral, disinterested parties.

“…Several recent studies (Damiani et al, 2014;Myers et al, 2013;Srinivas et al, 2014) have proposed a design paradigm that accounts for robustness and region-specific site hazards due to tropical cyclones and hurricanes. Indeed, efforts are underway to assess risks that result from using a conventional partial safety factor approach in combination with target return period environmental conditions for wind speeds, wave heights, and so on.…”

Hurricane risk assessment for offshore wind plants

This study describes a framework for estimation of structural damage to offshore wind plants during hurricanes. Related risk assessment is fundamentally dependent on the estimation of hurricane-generated wind speed exceedance probabilities at selected hub heights of wind turbines in the plant and on estimation of associated wind turbine loads. As part of a framework for risk assessment introduced here, synthetic storm tracks are first simulated over the ocean using available historical tropical storm data; then, a hurricane intensity evolution model based on thermodynamic and atmospheric environmental variables is developed for each simulated track as it approaches the chosen wind plant site. Based on this intensity model, a turbulent wind field can be simulated at any location of interest along the hurricane track. The simulated turbulent wind field can then be used to estimate wind speed exceedance probability distributions and, when combined with partially correlated waves, it can also be used in analyzing the response of individual turbines in a wind plant. A framework for the overall risk assessment is presented; individual components that are part of such a framework are described briefly in illustrative applications. Finally, a brief discussion is presented that addresses issues related to the concept of "robustness" checks that are often considered in the context of safe performance-based design. This concept employed in the oil and gas industries provides for a secondary margin for "beyond design-level" external conditions out to more extreme conditions as might accompany hurricanes.

“…Although IEC 61400-25 [35] aims at standardizing the communications protocols, it is still dependent on the OWF and WT manufacturers, to decide at what level of the system do they choose to apply the communication standard [56,57]. Besides, National Renewable Energy Laboratory (NREL) claims that the existing standards of IEC-61400 family are inadequate and to be modified for American offshore implementation [58]. They claim that the European establishments complement the standards with guidelines from DNV [59], and GL [60], which are customized for the local use.…”

This paper studies a conceptual architecture for health management of offshore wind farms. To this aim, various necessary enablers of a health management system are presented to improve reliability and availability while optimizing maintenance costs. The main focus lies on improving existing condition monitoring systems based on concepts of condition-based maintenance and reliability centered maintenance. A brief review of the relevant state-of-the-art is presented and gaps to be filled towards realization of such health management system are discussed.
