Book excerpt: There is a strong desire to increase the penetration of renewable energy sources inthe UK electricity market. Offshore wind energy could be a method to achieve this. However, there are still issues, both technical and economical, that hinder the development and exploitation of this energy source.A condition based maintenance plan that relies on fully integrating the input from condition monitoring and structural health monitoring systems could be the method to solve many of these issues. Improved maintenance scheduling has the potential to reduce maintenance costs, increase energy production and reduce the overall cost of energy. While condition monitoring systems for gearboxes, generators and main bearings have become common place over the last few years, the deployment of other monitoring systems has been slower. This could be due to the expense and complication of monitoring an entire wind farm. Wind park operators, correctly, would like to see proof that their investment will be prudent.To assist wind park operators and owners with this decision, an offshore wind operations and maintenance model that attempts to model the impacts of using monitoring systems has been developed. The development of the model is shown in this analysis: multiple methodologies are used to capture deterioration and the abilities of monitoring systems. At each stage benchmarks are shown against other models and available data. This analysis has a breadth and scope not currently addressed in literature and attempts to give insight to industry that was previously unavailable.

Book excerpt: A wind turbine is of course far more complicated than just a tower topped with a big fan, especially for the offshore ones. Wind energy as a green energy resource with zero fuel requirements, and thus no processing waste, has been assuming an increasingly important role in energy generation. Offshore wind farms with their steady output and low sensual impact have been gradually accepted by the public and authorities. Once built, the only cost for a wind farm is the operation and maintenance cost. Therefore, the question of how to reduce the failure rate and the operation and maintenance costs, and make offshore wind energy cheaper, is particularly pertinent, and is discussed in great detail here. This book details the various aspects of wind energy, and is accessible to the lay reader without any specialist knowledge. It explores the numerous concepts associated with offshore wind farm operation and maintenance with condition monitoring system, and vividly presents the the basics of wind energy, augmenting this with a large amount of valuable real wind farm case studies.

Available in PDF, EPUB and Kindle. Book excerpt: “Maintenance Management of Wind Turbines” considers the main concepts and the state-of-the-art, as well as advances and case studies on this topic. Maintenance is a critical variable in industry in order to reach competitiveness. It is the most important variable, together with operations, in the wind energy industry. Therefore, the correct management of corrective, predictive and preventive politics in any wind turbine is required. The content also considers original research works that focus on content that is complementary to other sub-disciplines, such as economics, finance, marketing, decision and risk analysis, engineering, etc., in the maintenance management of wind turbines. This book focuses on real case studies. These case studies concern topics such as failure detection and diagnosis, fault trees and subdisciplines (e.g., FMECA, FMEA, etc.) Most of them link these topics with financial, schedule, resources, downtimes, etc., in order to increase productivity, profitability, maintainability, reliability, safety, availability, and reduce costs and downtime, etc., in a wind turbine. Advances in mathematics, models, computational techniques, dynamic analysis, etc., are employed in analytics in maintenance management in this book. Finally, the book considers computational techniques, dynamic analysis, probabilistic methods, and mathematical optimization techniques that are expertly blended to support the analysis of multi-criteria decision-making problems with defined constraints and requirements.

This book was released on 2016 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Offshore wind energy is progressing rapidly and playing an increasingly important role in electricity generation. Since the Kyoto Protocol in February 2005, Europe has been substantially increasing its installed wind capacity. Compared to onshore wind, offshore wind allows the installation of larger turbines, more extensive sites, and encounters higher wind speed with lower turbulence. On the other hand, harsh marine conditions and the limited access to the turbines are expected to increase the cost of operation and maintenance (O&M costs presently make up approximately 20-25% of the levelised total lifetime cost of a wind turbine). Efficient condition monitoring has the potential to reduce O&M costs. In the analysis of the cost effectiveness of condition monitoring, cost and operational data are crucial. Regrettably, wind farm operational data are generally kept confidential by manufacturers and wind farm operators, especially for the offshore ones.To facilitate progress, this thesis has investigated accessible SCADA and failure data from a large onshore wind farm and created a series of indirect analysis methods to overcome the data shortage including an onshore/offshore failure rate translator and a series of methods to distinguish yawing errors from wind turbine nacelle direction sensor errors. Wind turbine component reliability has been investigated by using this innovative component failure rate translation from onshore to offshore, and applies the translation technique to Failure Mode and Effect Analysis for offshore wind. An existing O&M cost model has been further developed and then compared to other available cost models. It is demonstrated that the improvements made to the model (including the data translation approach) have improved the applicability and reliability of the model. The extended cost model (called StraPCost+) has been used to establish a relationship between the effectiveness of reactive and condition-based maintenance strategies. The benchmarked cost model has then been applied to assess the O&M cost effectiveness for three offshore wind farms at different operational phases.Apart from the innovative methodologies developed, this thesis also provides detailed background and understanding of the state of the art for offshore wind technology, condition monitoring technology. The methodology of cost model developed in this thesis is presented in detail and compared with other cost models in both commercial and research domains.

This book was released on 2018 with total page 42 pages. Available in PDF, EPUB and Kindle. Book excerpt: An offshore wind farm's cost of energy is, to a large extent, driven by operation and maintenance costs. Through the optimization of the maintenance strategies for offshore wind farms, the Levelized Cost of Energy (LCOE) will be further reduced, which will ceteris paribus lead to a higher competitiveness of offshore wind farms with other energy sources. This study pro-poses an event-based simulation of an offshore wind farm comprising 400 MW. The aim of the model is to minimize the total cost, and thus to maximize the revenues from the wind farm. Therefore, corrective, condition-based, and scheduled maintenance strategies are compared, and constraints, such as weather conditions and service team shifts, are taken into consideration. When hourly electricity spot prices are applied instead of feed-in tariffs, results show that weekly scheduled maintenance on a Saturday dayshift (starting at 8 am) is the most cost-efficient scenario. Condition monitoring systems have been found to be advantageous and are set as a standard application regarding the turbines. The impact of scheduled maintenance frequency, the distance between the offshore site and the coast, the interest rate, and altering reliability data are further analyzed.

This book was released on 2018 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Offshore wind energy is rapidly advancing as one of the cutting-edge renewable energy sources towards the global decarbonization goal. However, offshore wind energy is still twice as expensive as onshore wind. The Operational Expenses (OPEX) are responsible for a substantial portion. They constitute 25 to 30% of the total costs. Therefore, it is essential that market-leading operators like Ørsted redefine their maintenance strategies to make the sustainable technology more competitive. Digitalization has opened the doors to monitor the health state of the wind turbines and apply maintenance based on the risk to failure, but little investigation has been conducted to understand what is the actual impact of shifting to a condition-based maintenance strategy. This thesis develops a decision support tool for identifying the most cost-effective solutions for the medium to long-term maintenance planning of offshore wind farms. The model is based on time domain Monte Carlo simulations that analyze weather conditions, i.e., wind speed and wave height, models wind turbine failures and transportation systems such as Crew Transfer or Jack-up vessels, and schedules corrective, preventive and condition-based tasks. The model is tested on a hypothetical 80 wind turbine wind farm in the North Sea for a 10 years operation. The results show that Time-based Availability and Energy-based Availability increase more than 2% with a condition-based strategy. Production losses are reduced 10.72%.

Available in PDF, EPUB and Kindle. Book excerpt: Wind energy has an increasingly essential role in meeting electrical power demand and achieving environmental sustainability. The excellent offshore wind resource and the need to reduce carbon emissions from electricity generation are driving policy to increase offshore wind generation capacity in UK waters. Access and maintenance offshore can be difficult and will be more costly than onshore and availability correspondingly lower and as a result there is a growing interest in wind turbine condition monitoring allowing condition based, rather than responsive or scheduled, maintenance. Existing wind turbine condition monitoring methods, such as vibration analysis and oil debris detection, require expensive sensors. The additional costs can be substantial considering the number of turbines typically deployed in offshore wind farms and in addition, costly expertise is generally required to interpret the results. In contrast, the potential to extend the Supervisory Control and Data Acquisition (SCADA) data based analysis approach is considerable and could add real value to the condition monitoring with little or no cost to the wind farm operator. This thesis focuses on wind turbine condition monitoring that utilises exclusively data from SCADA systems. The aim is to detect incipient wind turbine operational faults or failures before they evolve to catastrophic failures, so that preventative maintenance or corrective action can be scheduled in time, hence reducing downtime and potentially preventing wider damage. Useful component condition indicators are derived by comparing incoming operational SCADA data with the results for relevant variables, like component temperature that reflect component condition, derived from relevant models trained on SCADA data from a healthy wind turbine. Incipient failures are identified through anomalous behaviour in the variables of interest manifest in the SCADA data. This approach is first applied to individual wind turbines, but then extended to include other wind turbines operating under similar conditions to derive component condition indicators through inter-machine comparison. This is demonstrated to facilitate significant savings in computational effort and model complexity compared to the repetitive development of individual turbine models. In addition, a real time wind turbine power curve is implemented based on SCADA data, and compared with a reference power curve to identify anomalous behaviour, through minor changes in the power curve, in a timely manner.

This book was released on 2015 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Offshore wind turbine technology is moving forward as an alternative to the fossil fuelled power production. However, there are a number of challenges in further offshore areas; wind turbines are subject to loads that are not often experienced onshore and more importantly challenging wind and wave conditions limit the operability and accessibility of the vessels needed to access offshore wind farms. Therefore, operating further from shore increases the logistic challenges of offshore wind operation and maintenance (O&M) activities. In contrast with the prospects, operational expenditure (OPEX) of the offshore wind farms has been increasing, reflecting greater risk for potential investors and current operators. As the power generation capacity improves constantly, advanced logistics planning of O&M activities, which supports the developers in achieving reduced downtime, optimised availability and maximised revenue, has gained vital importance. In order to sustain the competitiveness of the offshore wind industry against other renewable energy sources, the cost of offshore wind needs to come down to today's onshore cost. This cost reduction target can be achieved through improving the offshore related operations, which contribute the most to the OPEX of the offshore wind farms. Available vessels in the market and the variety of benefits & drawbacks of different vessel chartering strategies have to be considered in the O&M planning. In this research, an offshore wind operation and maintenance expenditure model has been developed. A time domain Monte-Carlo simulation approach is implemented, which includes analyses of environmental conditions (wind speed, wave height, and wave period), operational analyses of transportation systems, investigation of failures (type and frequency), and simulation of repairs. The model enables the quantification of the influence of cost drivers and provide an improved understanding about the key aspects associated with the operational decisions. The results of this research can assist offshore wind farm operators in developing midterm/long-term O&M plans. Through this extensive study, it is concluded that O&M related costs can be reduced significantly while availability and productivity of the turbines can be increased by selecting correct O&M fleet in terms of size and vessel capabilities.

Available in PDF, EPUB and Kindle. Book excerpt: The continuous growth in wind turbine power ratings and numbers has led to increased demands in inspection and maintenance due to the more significant financial and operational consequences of unexpected wind turbine failure. The fact that wind farms are commonly located at remote sites with potentially poor accessibility means it is necessary to reduce the need for corrective maintenance through evolution to preventive and prognostic maintenance activities. Prognostic repair schedules can be employed in order to optimise maintenance and contribute to the minimisation of the overall operational costs of wind farms. The present study presents the development and qualitative evaluation of remote condition monitoring methodologies for the evaluation of the wind turbine power electronics and gearboxes. The failures of power converter and gearbox components result in significant wind turbine downtime and associated repair costs. Effective condition monitoring can enable the timely diagnosis of faults in order to prevent unexpected failures and loss of electricity production, contributing towards a noteworthy increase the reliability, availability, maintainability and safety (RAMS) of wind farms. Within this study two customised test rigs have been employed to simulate various of faults and assess the capability of RCM in diagnosing this fault effectively. In addition, field measurements have been carried out and correlated to the findings of the test rig experiments. In this study, it has been possible to identify these variables qualitatively, but the quantitative investigation is still pending and will be most likely the subject of several future studies in this field. The present thesis provides a compact summary of the analysis of the key findings of the experimental work performed within the context of the OPTIMUS FP7 European collaborative project.

This book was released on 2011 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: This thesis reports on investigations undertaken into the reliability, availability and maintenance of offshore wind farms when considering different maintenance strategies, an understanding of which is fundamental when considering the technical and economical viability of existing and future offshore wind farms. A comprehensive literature review has been undertaken in the areas of offshore wind farm maintenance strategies, offshore wind turbine reliability and accessibility issues, and CO2 emissions associated with maintenance expeditions for offshore wind farms. The limitations and disadvantages of current maintenance practices are identified and a planned intervention maintenance policy is proposed and examined in detail. To help design a planned intervention maintenance policy, the offshore wind farm parameters that affect its technical and economical viability have been identified, which become the foundation for developing computer based models using Monte Carlo simulations to quantify the maintenance practices of the planned intervention maintenance policy. Different scenarios of the proposed solution are investigated to help quantify the technical and economical benefits over the current maintenance practises, in terms of wind farm availability, cumulative energy output, production cost of energy and CO2 emissions. The research on the reliability of offshore wind turbines has shown that the power converter system is a critical item that suffers from high failure rates. This thesis reports upon the investigation of a hot standby redundancy on the wind turbine power converter system. A redundancy model is deployed to simulate the planned intervention maintenance policy for different offshore wind farm case studies in order to establish the effects of the hot standby redundancy on the offshore wind turbine operational performance. The novel contribution of this work is claimed to be in the development of dedicated models for the reliability, availability and maintenance of offshore wind farms, which should lead in establishing a technical and economic benchmark for the parameters affecting offshore wind farms.
