Offshore Wind Turbine Blade Coating Deterioration Maintenance Model Jesse A Andrawus and Laurie Mackay School of Engineering‚ Robert Gordon University‚ Schoolhill‚ Aberdeen‚ AB10 1FR‚ UK Abstract Maintenance of offshore wind turbine blades has significant impact on the overall cost of managing offshore wind farms. Effective maintenance of protective coatings of wind turbine blades is one of the key challenges of offshore wind farms given that the current condition monitoring systems for

Steam Turbines The invention of the water turbine was so successful that eventually‚ the idea came about for extracting power from steam. Steam has one great advantage over water-it expands in volume with tremendous velocity. To be the most effective‚ a steam turbine must run at a very high speed. No wheel made can revolve at any speed approaching the velocity that a steam turbine can. By utilizing the kinetic energy of steam flow‚ the turbine could achieve a higher efficiency. As a result

Gas engines versus diesel engines have been a long time opponent. Each has its own pros and cons but its really what your needs demand. Power and torque is a big player in this. If you want higher horsepower and fast acceleration‚ a gas engine is for you. If you need to tow objects and need a lot of low-end power a diesel engine would suit you. Fuel economy can play a bigger part in your decision. Diesel engines usually have a better fuel economy rating because of the way they don’t waste fuel during

for large-scale offshore floating wind turbines was introduced by Professor William E. Heronemus at the University of Massachusetts in 1972‚ but it was not until the mid 1990’s‚ after the commercial wind industry was well established‚ that the topic was taken up again by the mainstream research community. Current fixed-bottom technology has seen limited deployment to water depths of 20 m. As the technology is advanced into deeper water‚ floating wind turbine platforms maybe the most economical means

Making Water Turbines Most Energy Efficient How does a wind turbine’s output vary with wind pressure (height of water)‚ the flow rate‚ size of the motor‚ and type of blade? Introduction There are many types of energy used today: Fossil fuels‚ coal‚ nuclear energy‚ solar energy‚ geothermal energy‚ hydrogen energy‚ hydroelectric energy‚ wind energy‚ and biofuels and biomass. Non-renewable energy sources such as fossil fuels and coal are diminishing since it cannot be recycled‚ unlike wind energy

HYDRAULIC TURBINES Meaning of the term ‘Hydraulic’ • The working fluid is a liquid or a gas?? ANSWER – WORKING FLUID IS A LIQUID. TURBINE – WORKING PRINCIPLE • In turbines the pressure energy is converted into mechanical energy(which is further converted into electrical energy). WORKING PRINCIPLE OF PUMPS it is just the reverse of the above‚ that is‚ the mechanical energy is converted into pressure energy. OUR FOCUS OF STUDY • Working of various types of hydraulic turbines. • Working
