Wave, tidal and offshore wind technologies have long held the promise of seemingly limitless energy supplies. In practice, while offshore wind is growing relatively rapidly, all three sectors have lagged behind expectations. This book, from the International Energy Authority Renewable Energy Technology Deployment implementing agreement (IEA-RETD), examines the reasons for this and suggests how barriers to deployment might be overcome. Beginning with an assessment of the marine energy resource, it provides a detailed introduction to the main technologies currently being employed to harness wind, tidal and offshore wind power. It then examines the types of policies which are used to encourage deployment around the world, and progress towards meeting targets. The economics of offshore energy projects are discussed, along with risks that projects face and the types of finance which are available. A final section turns to barriers - both technical and non-technical (including environmental, health and safety, skill related, supply chain and more) - and in all cases suggests how to mitigate and remove these barriers. Highly illustrated in full colour, this is an indispensable resource for anyone - whether in industry, policy or academia - looking to learn more about how deployment of offshore renewable energy technologies can be encouraged.

In 2007, the FAST wind turbine simulation tool, developed and maintained by the U.S. Department of Energy's (DOE's) National Renewable Energy Laboratory (NREL), was expanded to include capabilities that are suitable for modeling floating offshore wind turbines. In an effort to validate FAST and other offshore wind energy modeling tools, DOE funded the DeepCwind project that tested three prototype floating wind turbines at 1/50th scale in a wave basin, including a semisubmersible, a tension-leg platform, and a spar buoy. This paper describes the use of the results of the spar wave basin tests to calibrate and validate the FAST offshore floating simulation tool, and presents some initial results of simulated dynamic responses of the spar to several combinations of wind and sea states.

Abstract: Common deterministic cost of energy models applied in offshore wind energy installations usually disregard the effect of uncertainty of key input variables – associated with OPEX, CAPEX, energy generation and other financial variables – on the calculation of levelized cost of electricity (LCOE). The present study aims at expanding a deterministic cost of energy model to systematically account for stochastic inputs. To this end, Monte Carlo simulations are performed to derive the joint probability distributions of LCOE, allowing for the estimation of probabilities of exceeding set thresholds of LCOE, determining certain confidence intervals. The results of this study stress the importance of appropriate statistical modelling of stochastic variables in order to reduce modelling uncertainties and contribute to a better informed decision making in renewable energy investments.

Relative to first-order, second-order wave-excitation loads are known to cause significant motions and additional loads in offshore oil and gas platforms. The design of floating offshore wind turbines was partially inherited from the offshore oil and gas industry. Floating offshore wind concepts have been studied with powerful aero-hydro-servo-elastic tools; however, most of the existing work on floating offshore wind turbines has neglected the contribution of second-order wave-excitation loads. As a result, this paper presents a computationally efficient methodology to consider these loads within FAST, a wind turbine computer-aided engineering tool developed by the National Renewable Energy Laboratory. The method implemented was verified against the commercial OrcaFlex tool, with good agreement, and low computational time. A reference floating offshore wind turbine was studied under several wind and wave load conditions, including the effects of second-order slow-drift and sum-frequency loads. Preliminary results revealed that these loads excite the turbine's natural frequencies, namely the surge and pitch natural frequencies.

This report uses the offshore wind Jobs and Economic Development Impacts (JEDI) model and provides four case studies of potential offshore deployment scenarios in different regions of the United States: the Southeast, the Great Lakes, the Gulf Coast, and the Mid-Atlantic. Researchers worked with developers and industry representatives in each region to create potential offshore wind deployment and supply chain growth scenarios, specific to their locations. These scenarios were used as inputs into the offshore JEDI model to estimate jobs and other gross economic impacts in each region.

Essay from the year 2004 in the subject Politics - International Politics - Environmental Policy, grade: HD (High Distinction), Murdoch University (Institute for Sustainability and Technology Policy), course: Policy, Technology and Democracy, language: English, comment: Case study that explores how 'democratic' the decision making process concerning wind energy (ip. offshore) in germany was., abstract: Introduction Today s Windmills are taller than the cathedrals of the Middle Ages and the cooling towers of the atomic age. They are standing all over Germany and are sharply criticised as well as cheeringly advocated. At present, the discourse of the use of wind energy concentrates on building numerous and large offshore wind farms. In this paper, I will investigate how democratic is the policy and decision-making process concerning wind energy in Germany. This case study aims to demonstrate the current limits of democracy and suggest how more democratic practices could be implemented. In order criticise the policy, it is necessary to describe the political context in advance. The lead off will be made by some historic and technical aspects of this technology. Historic roots and technical aspects Humans have been using the energy of the wind for centuries. For example, there were over 200 000 windmills all over Europe in the 18t h century. However, the purpose of these windmills was grinding grain and squeezing seeds. The first installation to generate electricity was built by the inventor Charles F. Brush from Cleveland, Ohio in 1888. Apart from some deplorable attempts of the Nazis, wind power in Germany came (back) on the agenda with the oil crisis of 1973. In order to defy the price dictated by the sheiks, there was a lot of research concerning alternative energies. However, the effects are not worth mentioning. Nowadays, there are about 16000 windmills on land in Germany in order to produce electricity. Although this alternative form of electricity produ"
