Worst Engineering Disasters of All Time


While we as a species should be angry when corporations and governments take chances with our lives, like in the current Gulf Oil Spill, this kind of behavior should come as no surprise. In fact, organizations around the world have created some truly horrific catastrophes that they’d like to pretend never happened. Enjoy this shocking look at the dark side of greed.
The High Cost of Greed

5. Accidentally Draining A Lake

You can tell that this is going to be an intense article when the least catastrophic disaster mentioned is the accidental draining of an entire lake.
Lake Peigneur
It probably won’t shock you to hear that this slip up was caused by the oil industry, Texaco in particular. On November 20 1980, the date of the accident, the Diamond Crystal Salt Company was operating a salt mine beneath Lake Peigneur. The day was going just like any other, when a Texaco oil rig miscalculated its location and began drilling in search of oil.
As soon as a 14-inch (36 cm) drill bit breached the salt layer the water began to dissolve its way through the mine, rapidly expanding the hole as it flowed. What began is a relative trickle soon turned into a massive, swirling, vortex as the water broke upon the vast chasms that had been mined over the years. The water carved out such a large area that the formerly 10 foot deep lake almost immediately swallowed the oil rig and 11 barges into the whirlpool. The damage didn’t stop there, the lakebed began flowing into the hole as well, taking 65 acres of the surrounding land down with it.
So much water flowed into that hole that it actually reversed the flow of the Gulf of Mexico and turned a freshwater lake into a deep saltwater lake and radically changed the local ecosystem.
If you think an industry would learn to plan for the worst after a catastrophe of this magnitude, the next disaster will definitely napalm your ignorance.

4. Deepwater Horizon Oil Spill

On April 20th 2010 an explosion tore through the British Petroleum drilling rig Deepwater Horizon, claiming the lives of 11 crewmembers and rupturing the oil well, releasing an estimated 180 million gallons of oil to date (that’s a Valdez-worth of oil every four days).

British Petroleum (BP) was slow to respond, but despite the corporate attitude BP was exhibiting towards the incident, the US Federal Government left the response in the hands of the corporation. The intention was to instill a sense of accountability into an industry notorious for dumping its issues on tax payers. While it is almost universally agreed that the oil industry should be responsible for repairing the ills they inflict upon the environment, this lack of government intervention did nothing to stem the 1.5 million gallons a day that were leaking into the gulf.
Investigations into BP show that a corporate culture of cost reduction and a work-until-failure program that left knowingly faulty equipment in place until a catastrophic failure, purely with the intention of postponing the cost of a replacement. On the reverse, a look at the American culture shows a dangerously fiendish addiction to cheap oil and a willingness to mine anywhere for these chemicals despite the potential risks of doing so.

The use of dispersant is also a controversial one, as it has done nothing to actually remove the toxic chemicals from the environment. In fact, the 1.3 million gallons released into the gulf has simply hidden the true extent of the spill. That’s right – the spill is a lot worse than it seems. Dispersants allow the oil to mix with water, whereas it has the natural tendency to float on top of it. This has actually impeded the cleanup efforts as it renders simmers useless. Skimmer technology is based on shaving the top layer of water and grabbing/absorbing the oil that has floated to the top, which would work a lot more effectively if the oil wasn’t blended into the water itself.
Although the leaking well appears to be capped there could already be almost 200 million gallons of oil already drifting through the gulf posing a dire threat to the lives, and livelihoods, of the people living in the gulf states and countless birds, fish, dolphins and whales.

3.  The Three Gorges Dam

Once heralded as a potential cure for China’s growing energy crisis, The Three Gorges Dam project, a massive hydroelectric dam on the Yangtze River, has instead created several crises of its own.
Three Gorges Dam
Although the dangers of extensive damming have been known for generations, the Chinese government turned a blind eye to these warnings prior to and during the construction of these waterworks. Spanning over 2 kilometers across the Yangtze River and costing approximately $26 billion USD, the Three Gorges Dam was to serve as a symbol of China’s skyrocketing economy and mastering of nature but in Fall of 2007 even the Chinese government admitted that it may be “triggering landslides, altering entire ecosystems and causing other serious environmental problems—and, by extension, endangering the millions who live in its shadow.”
Map of the Dam
The direct impact to Humans living in the region was massive. As of June 2008, China had relocated 1.24 million residents and are now encouraging an additional 4 million to evacuate the region amid warnings of an “environmental catastrophe”. Entire cities have been abandoned, and countless ancient relics have also been lost to the rising tides. On top of these massive issues, the environmental consequences have been horrific. Desertification, salination and erosion are now running rampant. These photos show the amount of land degraded in just the immediate area around the dam itself!
Not all of the damage is restricted to the inland regions; River deltas (coastal regions where rivers meet a larger body of water) make some of the best fishing waters in the entire world as nutrients get picked up in the water as it moves downstream. This nutritious sediment, the base of the coastal food-chain, is blocked by the dam literally starving China’s fisheries. These issues are not just striking China but the entirety of Asia that now has to take on the burden of greater food shortages and having their waters more intensely fished.
At least the Chinese government has now witnessed first-hand the catastrophic impacts of this type of construction and are now working to remedy the situation … oh wait, they’re not. It turns out they have plans for 4 more massive dams even further upstream.

2. Chernobyl

It should come as no surprise that the Chernobyl incident, the world’s worst nuclear accident to date, has made it onto our list. On 26 April 1986, in the energy town of Chernobyl, an experiment was underway in reactor four of their nuclear power plant. Testing and continual construction was something the staff had grown accustomed to. Slated to become the world’s largest nuclear powerplant, it was the pride of the Soviet Union’s energy program. As this day would unfold, the experiment would rapidly spiral out of control.
Chernobyl Explosion
During the test, sensors picked up a massive energy spike in the reactant mass. Although this issue was not expected there were emergency systems in place for handling crises situations. The staff on duty initially did what their training dictated – flicking the release switch to plunge the uranium rods back into their water coolant tanks.
This should have been the end of the situation but was in fact just the beginning. The rods began to descend, but as their graphite coated tips struck the water a set of unlikely conditions lined up that created an even more massive burst of thermal energy upon contact. This surge shattered the radioactive rods and stopped the control system from submerging them completely.
Left uncooled, these rods reached tremendous temperatures (producing over 10x the normal rate of electricity) until finally causing the reactor chamber itself to explode. In an attempt to shirk responsibility it took days for the government to become fully aware of the situation and begin remedial action, leaving the reactant mass burning the entire time. The smoke of that fire contained four hundred times more radioactive material than was released by the atomic bombing of Hiroshima, causing large areas in the Ukraine, Belarus, and Russia to be evacuated (with over 336,000 people resettled) and drastically increasing the risk of cancer to the 600,000+ people exposed.

1. Bhopal Disaster

The night of December 2nd, 1984 is a night that will haunt the dreams of Indians for generations to come.
Bhopal Gas Tragedy
Around midnight there were strange things afoot at the Union Carbide pesticide plant in Bhopal, India. Mysteriously, a large amount of water entered storage tank 610, a which was being used to store over 42 tons of methyl isocyanate (a highly toxic and irritating material used in the making of pesticides). The intake of water resulted in an exothermic reaction and increased the temperature inside the tank to over 200 °C , far beyond the capacities of the tank. At this point automated emergency release systems kicked in, venting the extra pressure (and a large volume of gasses).
As methyl isocyanate is heavier than air, it crept along the ground and seeped into the nearby city of Bhopal. The citizens awoke in agony and in panic, as approximately 8,000 people died immediately from the effects of the gas and countless more were trampled in the streets. In total, over 16,000 people would die as a direct result of that fateful night while another 100,000 to 200,000 people are estimated to have suffered permanent injuries.
It has now been over 25 years since this horrific disaster but the 390 tons of toxic chemicals that were abandoned at the UCIL plantcontinue to leak and pollute the groundwater in the region

This image captures almost 6 hours of climbing parties on Rainier going for the summit under starry skies. Wind shifts during the night would cause bands of smoke from fires 100 miles away on Mt Hood to pass over Rainier. This intermittent low-level haze caused the red glow seen in the sky and a Rainier that looks like it was almost painted on.

An unexpected side-effect of the 2010 flooding in parts of Sindh, Pakistan, was that millions of spiders climbed up into the trees to escape the rising flood waters; because of the scale of the flooding and the fact that the water took so long to recede, many trees became cocooned in spiders webs. People in the area had never seen this phenomenon before, but they also reported that there were less mosquitos than they would have expected, given the amount of standing water that was left. Not being bitten by mosquitoes was one small blessing for people that had lost everything in the floods. (© Russell Watkins) #

This place is very special to me. The fèllensee is placed at the bottom of the hundstei (dog stone). I know this might sound silly, but since my dog and I grew up just around the corner and the naming of the mountain, I chose this very calm lake as a final resting place for Spock (my dog) so he would have the biggest gravestone of all dogs out there. That morning we had a farewell ceremony for Spock. I took this picture and we summited the hundstei to his honor (which was a very emotional challenge). This picture of his resting place is now hanging in our kitchen to remember him. (© Nino Benninger) #

This a portrait that I took of my Grandfather. He was a photographer and I wanted to show all his wonderful old cameras and his life in an editorial styled portrait. He just turned 95 years old and still remembers how all his old camera's work. I shot this with my cannon 7d body,and Tamron 17-55mm zoom lens. The lighting is with a 1200w Pro photo 2 head kit with 2 medium soft boxes. As well I used a 580 ex2 canon speed lite and diffused it with a paper lantern that I made into a diffusion for my speed lite. I really love this picture and hope you like it as well. (© Christopher Bellezza) #
Death valley averages just 1.58 inches of rainfall a year. Yet somehow, in my first trip there in four years, we catch a storm. Not just a storm, an electrical storm. At sunset, of all times. This was the reward for years of trips gone awry, blank skies, drenching downpours, and for every other cause of failed photography endeavors. To me, this is an example of the best thing that can happen to a photographer. To be in the right place, at the right time - and to not mess it up too badly. (© Jeff Engelhardt) #
Within an ultra modern society Japan still maintains to hold traditions passed down from generation to generation making it one of the most beautiful and intriguing places in the world. The city of Gion in Kyoto is one of those places that you will walk into and forget about all the flashing lights the rest of Japan has to offer. Its brick paved streets holds some buildings that have been maintained like the old traditional Japan. If you're lucky you will catch a glimpse of a beautiful geisha passing through the streets scurrying to her next appointment, make sure you have your camera ready. (© Clancy Lethbridge) #

One morning while on the Big Island of Hawaii, I was exploring my surroundings to see if I could find something to photograph. I almost went back inside when something on this huge palm tree leaf caught my eye. I stayed around and it was this little gecko, startled by my presence he was hidden between the ridges of the leaf. He would pop his head up periodically to check his surroundings; as soon as he saw I was still there he would hide again. We played this game for a while until I got the shot. (© Lorenzo Menendez) #
