Bolt tightening offshore: a crucial consideration
The Tin Man in the Wizard of Oz fretted over his joints, and wind turbines have the same problem. They need to be assembled offshore and maintenance of the joints is critical where a 20+ year life expectancy under the buffeting of winter seas and gusting storms is normal. The assembly is subject to prying forces, vibration and continuous temperature variation in a highly corrosive atmosphere of salt spray, rain and UV. Intellifast presents an illuminating despatch from the frontline of the wind energy arena...
Bolts are used to anchor the tower, for course assembly, and the nacelle. Many of these bolts are tightened close to yield. Each blade is attached to the hub with a large number of studs per blade. Any engineer who has recently experienced the snapping of
portfolios with potential
Jennifer Layke, Deputy Director, Climate and Energy Program, World Resources Institute, and Rick Bunch, Managing Director, The Erb Institute for Global Sustainable Enterprise at the University of Michigan, discuss a number of options for overcoming the real and perceived challenges to wind power purchasing.
‘Integration’ of renewable energy: what it..
A new buzzword is striking fear and excitement in the hearts and minds of renewable energy developers and transmission providers: ‘integration.’ The term can get stakeholders from all sides of the energy industry shouting across the table. It is also a sign of how far the renewable energy industry has come in making resources such as wind and solar energy a larger part of our domestic energy portfolio. So what does integration mean and how should we in the industry be feeling about it? In the context of renewable energy, ‘integration’ refers to a transmission provider’s use of balancing reserves to accommodate the natural variability of renewable resources.
Race is on to complete first US..
The battle lines are drawn for supremacy in the developing US offshore wind-generation business as various states vie to be the first to achieve that crucial milestone – going online. So what stage are we currently at in this all-important race? Jennifer Zajac of SNL Energy is your guide to the current movers and shakers … After years of encountering NIMBO, (Not in My Beautiful Ocean), sentiment and regulatory uncertainty, the US may finally see its first offshore wind project begin operations within the next three years.
Department of Energy: a change..
The US Department of Energy has traditionally concentrated its efforts and support on the oil industry, but in recent months it has shifted its stance towards renewables, and specifically towards wind energy, investing massive amounts in research and development and manufacturing. PES looks at the motivation behind this change and examines what economic factors and changes in the world’s markets may lie behind the department’s move Not since a certain Saul of Tarsus experienced the original Damascene conversion have we seen anything like it.
