Offshore Technology Yearbook Offshore Technology Yearbook 2 O19 Generation V: power for generations Since we released our fi rst offshore direct drive turbines, we have been driven to offer our customers the best possible offshore solutions while maintaining low risk. Our SG 10.0-193 DD offshore wind turbine does this by integrating the combined knowledge of almost 30 years of industry experience. With 94 m long blades and a 10 MW capacity, it generates ~30 % more energy per year compared to its predecessor. So that together, we can provide power for generations. www.siemensgamesa.com 2 O19 20 June 2019 03 elcome to reNEWS Offshore Technology are also becoming more capable and the scope of Yearbook 2019, the fourth edition of contracts more advanced as the industry seeks to Wour comprehensive reference for the drive down costs ever further. hardware and assets required to deliver an As the growth of the offshore wind industry offshore wind farm. continues apace, so does OTY.

NON-TECHNICAL SUMMARY 1.1 Introduction This document provides a Non-Technical Summary (NTS) of the Environmental Statement (ES) produced in support of the consent application process for the North West Lewis Wave Array, hereafter known as the development. The ES is the formal report of an Environmental Impact Assessment (EIA) undertaken by Lewis Wave Power Limited (hereafter known as Lewis Wave Power) into the potential impacts of the construction, operation and eventual decommissioning of the development. 1.2 Lewis Wave Power Limited Lewis Wave Power is a wholly owned subsidiary of Edinburgh based Aquamarine Power Limited, the technology developer of the Oyster wave power technology, which captures energy from near shore waves and converts it into clean sustainable electricity. Aquamarine Power installed the first full scale Oyster wave energy convertor (WEC) at the European Marine Energy Centre (EMEC) in Orkney, which began producing power to the National Grid for the first time in November 2009. That device has withstood two winters in the harsh Atlantic waters off the coast of Orkney in northern Scotland. Aquamarine Power recently installed the first of three next-generation devices also at EMEC which will form the first wave array of its type anywhere in the world. 1.3 Project details The wave array development will have the capacity to provide 40 Megawatts (MW), enough energy to power up to 38,000 homes and will contribute to meeting the Scottish Government’s targets of providing the equivalent of 100% of Scotland’s electricity generation from renewable sources by 2020.

There has been a clearer realization of the finite nature of oil resources and the ever higher pushing demand for energy. The world has yet to stabilize on the complex geopolitical undercurrents which influence the oil and gas production as well as supply strategies globally. Aruvian's R'search’s report – Analyzing the Energy Industry in United States - analyzes the scope of American energy production from varied traditional sources as well as the developing renewable energy sources. In view of understanding energy transactions, the report also studies the revenue returns for investors in various energy channels which manifest themselves in American energy demand and supply dynamics. In depth view has been provided in this report of US oil, electricity, natural gas, nuclear power, coal, wind, and hydroelectric sectors. The various geopolitical interests and intentions governing the exploitation, production, trade and supply of these resources for energy production has also been analyzed by this report in a non-partisan manner. The report starts with a descriptive base analysis of the characteristics of the global energy industry in terms of economic quantity of demand. The drivers of demand and the traditional resources which are used to fulfill this demand are explained along with the emerging mandate of nuclear energy.

  • The Impact of Pitch-To-Stall and Pitch-To-Feather Control on the Structural Loads and the Pitch Mechanism of a Wind Turbine

Pitch-to-feather control is widely used to limit the power output of wind turbines in high wind speed conditions. However, stall control has not been taken forward in the industry because of the low predictability of stalled rotor aerodynamics. Despite this drawback, this article investigates the possible advantages of this control concept when compared to pitch-to-feather control with an emphasis on the control performance and its impact on the pitch mechanism and structural loads. In this study, three HAWTs with different blade designs, i.e., untwisted, stall-regulated, and pitch-regulated blades, are investigated.

  • US Wind Turbine Manufacturing
    U.S. Wind Turbine Manufacturing: Federal Support for an Emerging Industry Michaela D. Platzer Specialist in Industrial Organization and Business September 23, 2011 Congressional Research Service 7-5700 www.crs.gov R42023 CRS Report for Congress Prepared for Members and Committees of Congress U.S. Wind Turbine Manufacturing: Federal Support for an Emerging Industry Summary Increasing U.S. energy supply diversity has been the goal of many Presidents and Congresses. This commitment has been prompted by concerns about national security, the environment, and the U.S. balance of payments. More recently, investments in new energy sources have been seen as a way to expand domestic manufacturing. For all of these reasons, the federal government has a variety of policies to promote wind power. Expanding the use of wind energy requires installation of wind turbines. These are complex machines composed of some 8,000 components, created from basic industrial materials such as steel, aluminum, concrete, and fiberglass. Major components in a wind turbine include the rotor blades, a nacelle and controls (the heart and brain of a wind turbine), a tower, and other parts such as large bearings, transformers, gearboxes, and generators. Turbine manufacturing involves an extensive supply chain. Until recently, Europe has been the hub for turbine production, supported by national renewable energy deployment policies in countries such as Denmark, Germany, and Spain. Competitive wind turbine manufacturing sectors are also located in India and Japan and are emerging in China and South Korea. U.S. and foreign manufacturers have expanded their capacity in the United States to assemble and produce wind turbines and components.
