Wind turbine failure yesterday in NS, off-topic


Recommended Posts

Someone needs to invest in a plant to burn our garbage.  Sweden does this in very modern high tech plants and diverts upwards of 98% of solid waste to create energy.  The plants are also VERY low emitters of GHG's.  

That would be something worth investing in as it kills 2 birds with one stone.

Even a reactionary place like Lee County FL (Fort Myers) has a large energy from waste plant.  They even collect aluminum cans out of the ash and make a few million dollars recycling them.  They get enough electricity to power the plant, offices and enough left over for a small town.

The next county north has a land fill site but because it is Florida, you can't really go down too far, so its just a large, ugly, smelly pile.  Just like Ontario used to do until they ran out of sites that would take it.  How many tons of hydro carbons do those trucks hauling Toronto and Mississauga garbage emit?

Precisely.  But mention the word "incinerator" and you will get a huge backlash because it is a dirty smog creating beast.  These people are stuck in theiir 1950s technology thinking.  As far as the carbon footprint goes a clean incinerator like the ones in Sweden are pretty much neutral.  Everything is reclaimed and cleaned.  It is cleaner energy than most as it also reduces landfill.

Looks to be the same type of failure as last years.
Blow for wind farm as S. Kent tower buckles

CHATHAM — Like a giant plastic straw bent in half, a wind turbine tower buckled over in rural ChathamKent, its motor and massive blades lying mangled on the ground.

No one was hurt in the tower collapse overnight Friday, said a spokesperson for the energy company that operates the wind farm.

But a spokesperson for a wind energy umbrella group said the failure appears to be only the second of its kind among the more than 6,400 wind turbines installed in Canada.

And the way the tower toppled over is unusual, said an official with a company that provides engineering software for manufacturers, including the wind energy industry, to design products with structural integrity to avoid fatigue failure.

“It looks like a major buckling of the tower at the midpoint, which is unlikely to be a fatigue failure,” Jon Oldred, vice-president of product management for HBM Prenscia, said from Southfield, Mich.

Reviewing a photograph provided by Postmedia News, Oldred said it appears an “extreme load of some kind” may have caused the incident.

Home to the largest number of wind turbines in Ontario, and the province’s largest wind farms, much of Southwestern Ontario — especially rural Chatham-Kent — is dotted with the giant electricity generators.

The tower is part of TerraForm Power’s Raleigh Wind Power project in South Kent.

“We are currently investigating the cause of the issue,” said Chad Reed, the company’s director of investor relations. “In the meantime, we have secured the immediate area around the turbine and taken the full facility offline as a precaution as we conduct a site inspection.”

Oldred said more common structural failures that occur with turbine towers happen in the gearbox for the blades, or with their shaft or mechanical aspects.

“They break quite regularly, but to have the whole tower fail — that’s more of a civil engineering problem, and I would say pretty unusual,” Oldred said.

Chatham-Kent police Sgt. Paul Pomajba said foul play is not suspected. He said TerraForm is investigating, and Ontario’s Labour and Environment ministries were contacted. “A number of other experts will be attending the scene to determine the cause of what has happened here today.”

Steve Mead, who lives three concession roads from the toppled turbine, said he’s long had concerns about the towers seeing several internet videos of blades that broke off and flew “great distances.”

“Now they’re falling apart here,” he added. “How safe are we?”

He said when the plan for erecting wind farms was first proposed, it was touted as safe renewable energy.

“I’m not feeling very safe right now,” Mead said. South Kent Coun. Karen Herman went to the scene of the collapse and said she was “speechless” at first sight.

“We need to find out what happened,” she said. “I can’t imagine this being a normal occurrence.”

She said she took a picture and shared it with council colleagues and Chatham-Kent civic managers.

“I’m just glad no one’s hurt, I think that’s the important thing here, right now,” she said.

A spokesperson for the Environment Ministry said the department is taking the incident seriously.

“Ministry staff are attending the site today to ensure that the company takes the necessary steps to contain and clean up any spilled materials,” the spokesperson said.

The ministry said TerraForm is bringing in specialists to assess the failure and arranging to have the damaged turbine removed. It has shut down all 51 wind turbines until the cause of the collapse is known.

Ministry staff weren’t aware of any similar incidents in the area before.
