Introduction:
Sayano – Shushenskaya Hydroelectric power station is located on the Yenisei River, near Saynogorsk in Khakassia. It was the largest hydroelectric power station in Russia and the sixth- largest hydroelectric power station in the world before. Construction started in 1968 taking 10 years for it to be built and opening in 1978. The plant was designed by the Leningrad. After the fall of the Soviet Union the Station was privatized with RAO UES becoming the main shareholder. RusHydro operated the plant, controlling the output of 10 turbines which each had the capacity of 640MW. The station was one of the largest contributors to the local electrical grid as well as more than 70% of the generated power going to Aluminum Company called Rusal’s four smelters in Siberia.
On the 17th of August 2009 at 8:13AM local time (00:13 GMT) at the Sayano- Shushenskaya Hydroelectric Power station a massive accident occurred when the structure, design, maintenance and safety checks of turbine 2 all failed each other and caused massive destruction and death.
Background:
The Sayano- Shushenskaya Hydroelectric Power Station was the largest hydroelectric power station in Russia. Operated by the RusHydro. On 17th of August 2009 at 8:13AM local time a major accident occurred. The water running turbine two ripped it out of position lifted it up 14 meters in the air, the turbine to continued to spin ripping concrete and scattering it around it. Eventually the Turbine hit the turbine cover supposedly held in place by 80 bolts each 8cm ripping it out of place and the 920-tonne rotor shot out of place hitting the room and surround wall of the turbine hall destroying the ceiling and surrounding wall. Due a series of short circuits other turbines bega...

...oss in the failure. Many villages and cities went with out power for a long period of time before power was restored.
The Solution to the aftermath of the accident was the spillway was regulated to decrease the water level of the reservoir by 3 to 5 centimetres. Floodwater was pumped out from the engine room by 24 August 2009. On 28 August, the search and rescue operation was completed, and the state of emergency imposed in Khakassia on 17 August 2009, was lifted. The solution to the massive power loss was the accelerating the construction of the Boguchany hydroelectric power station to replace the lost generating capacity. Chemical Sorbents were used to soak up the oil spill in Yenisei River and was fully removed by 25th of August 2009. 19th of August was declared a mourning day in Khakassia and 25th of August was declared a mourning day at the RusHydro Company.
Furthermore, even though the Friend dam is the first primary purpose of it; it also follows a secondary purpose also. And that would be the Friend Power Authority which has 4 power plants. And within the plants it has turbines in it. What this turbine does it is that it generates water into the channel or tubes, and then it let it out into the four outlets which flows out into its benefits locations.
The series of events that occurred on April 26th, 1986 at the Chernobyl Power Plant located in the Ukraine, would be considered one of the worst disasters that the world would ever see. It was supposed to be a routine check “to determine how long the steam-driven turbines at the plant would continue to generate electricity in the event of an electrical blackout” (Worsnop). This seems ironic because a simple test led to such a complicated calamity. During the test, one of the turbines was shut off and the emergency core cooling system was turned off as well. For a simple test, turning off the emergency core cooling system all together might not have one of the best options. They were running the core at low power and by doing so it caused excess xenon to accumulate. By reducing the water flow to the core, the core stared to heat up rapidly causing the reactor power to increase. Finally, they figured that they should remove the control rods from the reactor core as an emergency shutdown method. However, all the events leading up to this point did the opposite of shutting...
Every so often workers have to go up the tower and unwind the wire that is located in the generator at the top of the tower (Campbell). The reason they have to unwind the wire is so the wind turbine can turn into the wind to create energy. These wind turbines only rotate one way, they don’t rotate both ways, so after a while the wire turning the wind turbine tightens and the wind turbine is unable to turn anymore. So the workers have to go up to the generator of the wind turbine and unwind the wire manually (Campbell). Also, with all the wiring and gears up in the generator, workers have to go up the ladder which is found on the inside of a turbine, and check to make sure everything is alright (Gipe).
At the end I come to conclusion that BP was not properly prepared for any disaster like that there risk assessment related to project is very limited and even not considered seriously about it for their own progress and putting live of public and employees in danger by not following the standard SOP of particular project. Even after incident happened they try to close their eyes on reality. The company should take this incident as alarm and should implement proper risk assessment for future and also compensate damages on ethical ground and if they counter this situation in good way their loss of bad reputation will be lesser as it predicted to be they should considered their responsibility towards society as well by doing this they not only making other people lives better but also earning good will to their company.
The use of turbines from dams to provide power was a brilliant idea until water levels started running lower than normal. The water waste from humanity is directly contributing to portions of it, aside from drought conditions affected by pollution, widespread fires battled, and more adds to the depletion thereof. When humanity is relying on power provided from dams to handle the demand, they are essentially relying on the assumption that water levels will always be there to provide it. The Hoover Dam provides power to the southwestern portion of the USA that has a large number of people.
Countless engineering disasters have occurred in this world, many civilians lost their lives due to corrupted constructions. The most fatal and deadly engineering disaster that took place in our history was the Chernobyl disaster. The Chernobyl catastrophe was a nuclear setback that happened at the Chernobyl Nuclear Power Plant in on April 26, 1986. It is seen as the most recognizable terrible nuclear power plant cataclysm ever. A nuclear crisis in one of the reactors caused a fire that sent a cluster of radioactive consequence that on the long run spread all over Europe.
“Workers at the plant were performing tests on the system. They shut off the emergency safety systems and the cooling system, against established regulations, in preparation for the tests. Even when the warning signs of dangerous overheating began to appear, the workers failed to stop the test. Xenon gases built up and at 1:23 a.m. the first explosion rocked the reactor. A total of three explosions eventually blew the 1,000-ton steel top right off of the reactor” (History).
I. (Gain Attention and Interest): March 11, 2011. 2:45 pm. Operations at the Fukushima Daiichi Nuclear Power Plant continued as usual. At 2:46 pm a massive 9.0 earthquake strikes the island of Japan. All nuclear reactors on the island shut down automatically as a response to the earthquake. At Fukushima, emergency procedures are automatically enabled to shut down reactors and cool spent nuclear fuel before it melts-down in a catastrophic explosion. The situation seems under control, emergency diesel generators located in the basement of the plant activate and workers breathe a sigh of relief that the reactors are stabilizing. Then 41 minutes later at 3:27 pm the unthinkable occurs. As workers monitored the situation from within the plant, citizens from the adjacent town ran from the coastline as a 49 foot tsunami approached. The tsunami came swiftly and flooded the coastline situated Fukushima plant. Emergency generators were destroyed and cooling systems failed. Within hours, a chain of events led to an explosion of reactor 1 of the plant. One by one in the subsequent days reactors 2, and 3 suffered similar fates as explosions destroyed containment cases and the structures surrounding the reactors (Fukushima Accident). Intense amount...
In the past, the United States has already repeatedly occurred the blackout. Especially in 1977, there was a large-scale power outages and the city became a big mess. At that time, blackout of 1977 not only resulting in significant economic losses, but also a power shortage triggered kind of serious public problems. It could be the strong contrast with the past blackout, so the blackout of 1977 was more striking and deeply impressive.

It often requires isolation of systems to get the components back on line and at full operational range before restoration commences.
One of the most significant environmentally damaging instances in history was the Chernobyl incident. In 1986, the Chernobyl Nuclear Plant in Ukraine exploded. It became one of the most significant disasters in the engineering community. There are different factors that contributed to the disaster. The personnel that were tasked with operating the plant were unqualified. The plant’s design was a complex one. The RBMK reactor was Soviet design, and the staff had not be acquainted with this particular design. As the operators performed tests on the reactor, they disabled the automatic shutdown mechanism. After the test, the attempt to shut down the reactor was unsuccessful as it was unstable. This is the immediate cause of the Chernobyl Accident. It later became the most significant nuclear disaster in the history of the
The impoundment facility is the most seen type of hydropower plant. This facility is a large hydropower system that uses a dam to store water in a reservoir. The water that is released from this reservoir then flows through a turbine, which causes it to spin, activating a generator to create electricity.

One of the worst cases of catastrophic event in history is the Bhopal Union Carbide case.
On April26, 1986, the nuclear power plant was exploded in Chernobyl, Ukraine. At 1:23 AM, while everyone were sleeping, Reactor #4 exploded, and 40 hours later, all the city residence were forcefully moved to other cities, and they never return to their home. The Chernobyl disaster is ranked the worst nuclear accident. The Chernobyl nuclear power plant was ran by the Soviet Union central nuclear energy corporation.
