In Tauranga, the oil spill have had ‘gone’ public minds – I have seen public beaches previously ‘closed’ and now ‘back to normal’ . The waste and its impact, however, is still being dealt with ….  This from the Bay of Plenty Times | twitter.com/#!/LearnFromNature & twitter.com/#!/NAEE_UK

 

About 2325 tonnes of waste from the stricken cargo ship Rena has been processed since it ran aground off Tauranga in October, clean-up company Braemar Howells show.

Of that, 1870 tonnes has gone into landfills while 117 tonnes has been liquid waste, mostly blood from meat freezers.

Around 177 tonnes of the rubbish was collected from Waihi Beach and 77 tonnes from Matakana Island.

About 25 tonnes of milk powder has been collected and 120 containers have been processed by Braemar Howells.

The figures include waste which washed ashore and waste collected from the sea.

Braemar Howells spokeswoman Monique O’Connor said the company was prepared to deal with the same amount of waste again, but it was unclear how much more would be washed from the ship.

“A lot of that depends on what’s happening on board, which depends on what’s happening with weather conditions. It’s in the lap of the gods really.

“The clean-up is very much an ongoing operation. Initially it focused on the western Bay of Plenty because debris was focused nearer the Rena but it’s now a far greater area, it’s spread far to the north and south.

“We have vessels and people working constantly targeting different areas at different times.”

One of the aims this week was to recover containers holding timber which had washed up at two secluded beaches north of Waihi Beach, she said.

Brazil Chevron Oil Spill ? : Up To 2,600 Barrels Leaked

Huffington Post News

Nearly 110,000 gallons of oil may have spilled into the Atlantic Ocean because of a leak at an offshore Chevron drilling site, Brazil‘s environmental protection agency said Friday.

Officials think between 8,400 to 13,800 gallons of oil leaked each day from Nov. 8 through Tuesday, Ibama said in a statement on its website. Chevron had said that only 16,800 to 27,300 gallons in total leaked into the ocean.

Officials are still investigating the cause of the leak, which has been almost entirely contained, but the Ibama statement said it was a result of drilling.

An official at Brazil’s Federal Police, which has opened an investigation into the spill, said Chevron “drilled about 500 meters (1,640 feet) farther than they were licensed to do.” The official, who agreed to discuss the matter only if not quoted by name, said that information came from a person with knowledge of the drilling.

The leak occurred at a drilling site about 230 miles (370 kilometers) northeast of Rio de Janeiro.

Rio state Environment Minister Carlos Minc said earlier he was sure the leak was larger than Chevron estimated and he called for more transparency from the company.

“We can’t trivialize this,” he told the Globo TV network. “It’s really serious and we don’t yet know all the consequences.”

Marine life in the area of the spill will be affected by the leak, Minc said, adding that whales are migrating from north to south through the spill area.

The oil slick, which was moving away from the coast, grew to 11 miles (18 kilometers), Ibama said. Most of the oil was concentrated around the drilling rig in a layer about 3 feet (1 meter) thick.

 

Chevron said “current estimates place the volume of the oil sheen on the ocean surface to be less than 65 barrels.”

The company said it has 18 ships working on a rotating basis to collect oil off the surface and monitor the slick.

The drilling contractor for the well is Transocean Ltd., the owner of the Deepwater Horizon rig that oil company BP PLC was leasing at the time of last year’s Gulf of Mexico oil spill, the largest in U.S. history and one that dwarfs the Brazilian leak. At its peak, BP’s Macondo well was spewing more 2 million gallons a day.

Chevron said cementing operations were taking place so the well off Brazil is plugged. ANP, Brazil’s national petroleum agency, said in a note on its website that “the first stage of cementing, to permanently abandon the well, was successfully completed.” The regulator said the success of permanently plugging the well would be known “in the coming days.”

ANP also said underwater footage showed that a “residual leakage flow” was continuing, but that “the oil slick continues moving away from the coast and is being dispersed, as desired.”

Fabio Scliar, head of the Federal Police’s environmental affairs division, which is investigating the case, said those responsible would be held accountable.

“There is no doubt that a crime occurred. The spill comes from the drilling activity. What interests me now is to find who is responsible,” Scliar was quoted as saying by the newspaper Folha de S. Paulo.

The oil is believed to be coming from seep lines in the seafloor near the well and not from the well itself. Natural seeps are common around the world – perhaps the most well known in the U.S. is the La Brea Tar Pits in the heart of Los Angeles – and are often used by oil companies during undersea exploration to determine where a good prospect for oil drilling may be.

Natural seeps are usually so small in volume they don’t cause a nuisance beyond producing the periodic tar ball that washes up on a beach.

But problems with drilling a well nearby can exacerbate the seeps and cause greater flow of oil, which can be hard to control, said George Hirasaki, a Rice University engineering professor who was involved in the Bay Marchand oil containment effort for Shell off Louisiana in the 1970s.

“Anytime there is movement of fluids, even if it didn’t go to the surface of the well, the internal flow could result in the fluid going somewhere else,” Hirasaki said. “It could move laterally at the same depth or increase the flow rate of natural seeps that are connecting to the surface.”

Investigators will want to look at whether the weight of the mud being used during the drilling and abandonment operations was sufficient to contain the pressure inside the well, and they will also want to see whether drilling too deep caused problems in a geopressure zone beneath the seafloor, experts said.

Ed Overton, a Louisiana State University environmental sciences professor, said that to truly control the leak could be difficult.

“If you have this stuff oozing up through the ground you don’t have a mechanism for control,” Overton said. “If something started that to leak, that would worry me a lot more than a leak around the well. You’d have to drill a relief well and intercept that ooze.”

People familiar with last year’s BP oil spill off Louisiana know about relief wells.

BP spent four months drilling a relief well that it used to pump cement under the area that was spewing oil into the Gulf of Mexico, and sealed the leak permanently.

Experts said that while there are many physical differences between the BP spill and the Chevron spill, the main common thread is the slow flow of information and different explanations for what happened and the severity of what happened.

“There’s a pretty long track record of all the people involved in spills underestimating at least initially the size of the spills,” Overton said. “I would suspect they literally don’t know, so they are trying to figure out.”

The Chevron leak is smaller than those Brazil has seen in the past.

In 2000, crude spewed from a broken pipeline at the Reduc refinery in Rio de Janeiro’s scenic Guanabara Bay, spewing at least 344,400 gallons into the water. Just a few months later, more than 1 million gallons of crude burst from a pipeline state-controlled oil company Petrobras into a river in southern Brazil.

Brazil’s worst oil disaster was in 1975, when an oil tanker from Iraq dumped more than 8 million gallons of crude into the bay and caused Rio’s famous beaches to be closed for nearly three weeks.

Two weeks after the Liberian-flagged Rena got stuck on a reef off New Zealand’s east coast, the 47-tonne oil container ship’s captain and navigational officer appear in court in Tauranga. They are charged under the Maritime Transport Act with operating a vessel in a manner causing unnecessary danger or risk. The Guardian video

Oil spill : BP disaster documentary rakes over big questions

Anchor-handling tugboats battle the blazing re...

The Big Fix raises concerns over Obama administration’s use of toxic chemical Corexit and BP’s leverage in the crisis. The Guardian reports

It’s not every film that sets off on a mini-road trip with Peter Fonda, only to veer off into a night-vision goggle surveillance of a BP facility.

 

But then, the events of last year’s BP oil disaster have so far been largely revisited in books, not documentaries. Until now, when a newdocumentary about the Gulf of Mexico oil spill has its premiere at the New Orleans film festival.

 

The Bix Fix, by Josh and Rebecca Tickell, re-opens some of the most persistent questions about last year’s oil spill. How BP was able to exert so much control over the crisis as it unfolded? What were the long-term health consequences of using a toxic chemical, Corexit, to break up the oil and drive it underwater?

 

Rebecca Tickell herself had a serious reaction to the chemical after being out on the open water – and as it turned out so did the doctor she consulted in an Alabama beach town. She still has health problems.

 

Josh Tickell, who grew up in Louisiana, said the Obama administration‘s decision to allow the use of Corexit, which is banned in Britain, was the biggest surprise in the making of the film.

 

“The most shocking thing to me was the disregard with which the people of the Gulf region were dealt,” Tickell said.

 

“Specifically I think that there was sort of a turn-a-blind-eye attitude towards the spraying of dispersants to clean up the spill. I don’t think anyone wanted to look too deeply at the consequences.”

Oil Spill : Rena likely to split apart on New Zealand reef

 

A disaster is quite possibly revealing itself off Tauranga’s coast – my home town. The ‘Bay of Plenty Times’ has the latest.  

Large fractures in the hull of the stricken cargo ship Rena are getting worse, increasing the chances the ship will break up.

Aerial footage taken by TVNZ shows the hull of the vessel has cracked open.

Prime Minister John Key this afternoon said on Wednesday the substantial fractures in the vessel made it much more likely to break up on the reef.

He defended the amount of time it had taken the Government to respond to the disaster, saying the operation had been carried out as swiftly as possible.

“I can understand people wanting to believe that this could be fixed more quickly. But the Government doesn’t hold a magic wand

“We are moving as quickly as we can.”

Salvage team captain John Walker said the condition of the ship was deteriorating.

Three tugboats were ready to head to the Rena to try to pump more oil out of it if weather conditions allowed, he said.

A Maritime New Zealand spokesman said it was possible a fuel tank could be ruptured if the Rena broke up – allowing more oil to leak into the sea.

However, salvage teams had capped the tanks before leaving the vessel and it was possible no more oil would escape, he said.
