Oil spills kill a lot of wildlife quickly, but their long-term effects are hard to establish because to compare the situation before and after a disaster, a study would need to have been already up and running before the disaster occurred. Fortunately, this was precisely the case for a Spanish team of researchers.

Back in 1994, marine biologist Álvaro Barros and his colleagues at Spain’s University of Vigo started looking at the reproductive activity of 18 colonies of a diving bird known as the European shag (Phalacrocorax aristotelis). Then, on 13 November 2002, the hull of the Prestige oil tanker broke in half off the north-western coast of Spain, releasing 63,000 tonnes of oil. The oil heavily coated regions near seven of the colonies, and mostly missed the other 11, creating ‘oiled’ and ‘unoiled’ populations for the researchers to compare.

The team now reports in Biology Letters1 that reproductive success was 45% lower in oiled populations compared with unoiled colonies, whereas it had been much the same before the spill. The researchers measured reproductive success by counting how many fully grown young emerged from each nest. This number averaged 1.6 for both oiled and control colonies before the spill. Afterwards, while the control colonies maintained the 1.6 figure, the number for the birds in the oiled colonies dropped to 1.0.

“We just don’t have much information on long-term oil-spill effects. That this team was able to compare colonies like this over so many years makes the findings very valuable,” explains ecologist David Grémillet at the CNRS Centre for Functional and Evolutionary Ecology in Montpellier, France.

Barros and his team did not investigate why reproductive success was so much lower in the oiled colonies, but speculate from their knowledge of other studies that it resulted from wider ecological damage. “It looks like many of the shags’ preferred prey were wiped out, and that a lot of oil pollutants got incorporated into the ecosystem. This would certainly harm their ability to reproduce,” Barros explains.

MOBILE, Alabama — Alabama’s beaches are back in business, finding favor with tourists once again. There is, however, still more work to be done. Stakeholders agree offshore drilling continues to be risky endeavors thousands of miles beneath the Gulf of Mexico.
It took the blowout of the Macondo well, a ruinous gusher that leaked for 87 days, to shed a light on the caustic trade-off for powering cars, televisions and central air conditioners.

Some fear subsea energy exploration, an unforgiving endeavor, still carries on despite a deficit of safety reforms four years after the 2010 Deepwater Horizon oil spill. And regulators of the country’s offshore oil and gas industry are looking into an unlikely way to monitor shortcomings on rigs: allow the companies to report incidents themselves.
The “near-miss” reporting system partially administered by the Bureau of Safety and Environmental Enforcement would have companies voluntarily submit confidential reports that will be aggregated into a snapshot of the industry’s soundness.

Brian Salerno, the agency’s director, said last month that the reporting system “has the potential to help prevent catastrophic incidents that endanger lives and the environment. However the tool is only as good as the information provided.”

The idea mimics a common practice in the aviation industry, allowing a third party, in this case the Bureau of Transportation Statistics, to collect the information. They’re making their pitch to industry this week at meetings in Los Angeles and Houston.
But the well-meaning program is far from what a skeptical public had hoped for.

In the months after Deepwater Horizon, sweeping reform seemed inevitable. The events, which at one point carried so much urgency, have become deflated around action in courtrooms.

When more than 200 million gallons of oil was set free into the Gulf, it exposed more than a few issues. In response, a presidential commission prescribed a number of recommendations to bolster drilling safety.

“If you want to know how far we’ve come since Horizon, use that as your baseline,” said Richard Charter, a senior fellow with the Ocean Foundation. “You look at the check list on the executive summary and not much has changed.”

In deference to the report, the Minerals Management Service was split into two agencies — one for safety and another for development — to eliminate conflicting interests. Today the agencies still confront workforce development challenges, seeking to pull from the same pool of candidates as the moneyed oil industry.

Some of the same technology that failed in 2010, such as the blowout preventer, is still in use today.

“The need to be precautionary is second to none–other than the nuclear industry,” Charter said. “Levels of redundancy have worked in the nuclear industry and in space, but for some reason it has not translated to the oil and gas industry.”

Having been allowed to bid on new leases last month, BP’s operations are crucial to testing the new self-reporting system.

A settlement reached in March with the Environmental Protection Agency requires the British oil giant to take part in the bureau’s “near-miss” program.

The Center for Offshore Safety, an industry-backed organization that was formed after the spill, has led with a similar program of its own.

Charlie Williams, former chief scientist for well engineering at Shell worldwide, runs the outfit based in Houston. They count some of the biggest companies doing business in the Gulf among the members who participate.

“The purpose of all this is all aimed at what can we learn, and determine what some of the best practices are,” Williams said. “The ultimate challenge is having a robust safety culture where everybody is individually responsible.”

They’ve only received the first wave of data in November, he said, and has not been able to use the information yet.

As the country moves toward a so-called “all of the above” energy policy, safety concerns associated with offshore drilling will only persist as the government moves to expand exploration into the Arctic, and possibly the Atlantic coast.

The energy rush has occurred, all while most of the long term effects of the oil spill remain unknown, said Sierra Weaver, a senior attorney with the Southern Environmental Law Center in North Carolina.

“We are extremely concerned about the prospect of drilling off the coast of the Southeast (United States),” Weaver said. “These things tend to be out of sight, out of mind.”

The chances of a government program succeeding, Charter said, depend on motivation.

“The motivation for protecting your corporate image from the visible effects is stronger for airlines than for deepwater drillers,” he said. But when you’re miles out into the Gulf “accidents are generally not visible.”

WWNO: Telltale Rainbow Sheens Show Thousands Of Spills Across The Gulf

The 300,000 wells drilled in Louisiana are connected by tens of thousands of miles of pipelines that are vulnerable to leaks, like this one in a coastal marsh. Gulf Restoration Network

Jonathan Henderson of New Orleans-based Gulf Restoration Network is flying Louisiana’s coast looking for oil. As usual, he’s found some. Just in the last year, I have filed 50 reports for different leaks and spills unrelated to the BP disaster.- Jonathan Henderson, Gulf Restoration Network. “I just noticed something out of the corner of my eye that looks like a sheen that had some form to it,” he says. “We’re going to go take a closer look and see if there’s a rainbow sheen.”

It’s a target-rich environment for Henderson, because more than 54,000 wells were planted in and off this coast – part of the 300,000 wells in the state. They’re connected by thousands of miles of pipelines, all vulnerable to leaks. And leak they do. Louisiana admits to at least 300,000 barrels spilled on its land and in its waters each year, 20 percent of the nation’s total. But those figures come from a system that depends largely on oil companies to self-report.

The problem went mostly unnoticed until the largest spill in U.S. history back on April 20, 2010, drew environmental groups to the coast looking for BP’s oil. “I started noticing, towards the end of 2010, other leaks that were unrelated to the BP disaster,” Henderson says. “I would find wellheads that were leaking or platforms that were leaking. Just in the last year, I have filed 50 reports for different leaks and spills unrelated to the BP disaster.”

Under the Clean Water Act, when a company spills any amount of oil in the water, it must file a report with the National Response Center run by the Coast Guard. But when Henderson checked, he found many of those smaller spills were not making that list. So environmental groups formed the Gulf Monitoring Consortium to get a better count on spills. The partnership is a blend groups of complementary skills.

Gulf Restoration Network, for example, has personnel who can spot spills from the air and file complete reports. SouthWings, a group of volunteer pilots, helps get those spotters aloft. A third member, the West Virginia-based tech group SkyTruth, finds the spills on satellite photographs, then applies a formula used by spill experts to translate the size of the oil sheen into gallons of oil in the water.

SkyTruth spokesman David Manthos says its estimates typically are much higher than what’s been reported. “We found that the spill was usually 10 times larger than had been reported, and that was averaged out across a lot,” he says. “In some, the mismatch was much larger than that.”
The sheer size of the industry here means there’s seldom a quiet day for the consortium. In an average year, the NRC receives 10,000 reports of spills in the Gulf.

It’s a number that surprised even SouthWings Gulf Program Director Meredith Dowling, a veteran of monitoring efforts. “I can’t think of a single instance where our volunteers have flown offshore and not found spills,” Dowling says. “This was something that was really amazing to me when I first moved here … that is was a continuous, absolute failure of business-as-usual practices.”

The partners hope their work educates the public to the scope of the problem, and perhaps gets governments to end the voluntary compliance model and turn to aggressive enforcement by outside groups.

GALVESTON, Texas – An offshore drilling rig is taking on water but is stable after being hit by a large storm wave off the Texas coast.

The U.S. Coast Guard says the rig was drilling for oil and gas in 3,000-foot depths around 10 a.m. Tuesday when the wave hit.

Petty Officer Manda Emery says the platform was knocked 55 feet, and one of three watertight chambers in one of the rig’s six floatation columns began taking on water.

Emery says the platform is being kept level and there is no spill. None of the 116 crew members was injured, and there have been no evacuations.
The rig is about 130 miles from Galveston.

Coast Guard Petty Officer 1st Class Andy Kendrick says the well is being drilled for Houston-based Anadarko Petroleum

Coast Guard monitoring damaged drilling rig in Gulf of Mexico
Apr 15th, 2014 · 0 Comment

HOUSTON – The Coast Guard is overseeing response efforts for an offshore drilling rig that began taking on water into a ballast tank after a large wave hit them in heavy seas more than 100 miles south of Galveston.

Tuesday morning the Coast Guard received a report that the ENSCO 8506, an offshore semi-submersible drilling rig, had been damaged causing one of the rig’s column ballast tanks to take on water. The capacity of the ballast pumps onboard are keeping up with the ingress of water in the column ballast tank. The rig is maintaining an even keel and remains in a stable position without resorting to using the emergency pumps, or performing an emergency disconnect from the riser.

There are no reports of injuries or pollution.

The rig was conducting exploratory operations and did not have any oil product onboard from drilling operations. The drilling rig is operating in an area with a 3,800-foot water depth and was not conducting actual drilling operations when the incident occurred. All rig operations have been suspended and preparations are being made for normal disconnect procedures if necessary to make repairs.

The Coast Guard has deployed the Coast Guard Cutter Skipjack, homeported in Galveston, and an aircrew aboard an HU-25 Falcon airplane from Coast Guard Air Station Corpus Christi to provide on-site intelligence and to assist if necessary.

The onscene weather Tuesday afternoon was 20 knot sustained winds and 12 foot seas.

Takepart.com: 6 Horrible Oil Spills Since Deepwater Horizon That You Probably Didn’t Hear About

By Kristine Wong | Takepart.com 17 hours ago Takepart.com

On April 20, 2010, the giant Deepwater Horizon oil rig, owned by Transocean Inc. and operated by BP, exploded some 50 miles off the Louisiana coast, killing 11 crew members before sinking into the Gulf of Mexico two days later. The rig’s underwater well, called Macondo, was 5,000 feet below sea level. The extreme environment-and, critics contend, lax oversight and governmental regulation-made it hard to stanch the flow of oil into the sea. By the time Macondo was finally capped on July 15, more than 210 million gallons of oil had leaked into the Gulf of Mexico, making it one of the largest environmental disasters in United States history.

Though environmentalists pounced on the accident as an occasion to push for an end to our oil-dependent lifestyles, BP and its big oil brethren have continued to rake in outsize earnings. In 2013, BP, Chevron, ConocoPhillips, Exxon Mobil, and Shell took home $93 billion in profits-that’s $177,000 per minute. The accidents haven’t stopped either.

Here are six of the largest oil spills around the world that have occurred since that fateful day nearly four years ago.

Little Buffalo, Alberta
On April 29, 2011, more than 868,000 gallons of crude oil from Plains Midstream Canada’s Rainbow Pipeline spilled into a forest 20 miles from the Lubicon Cree First Nation community of Little Buffalo, Alberta. Three hectares of beaver ponds and swampland were contaminated. Many residents reported experiencing headaches and nausea from the fumes. Two years after the spill, Plains Midstream was fined for violating Canada’s Environmental Protection and Enhancement Act. The spill was considered to be Alberta’s worst in 35 years.

Kalamazoo River, Michigan
A pipeline transporting diluted bitumen-aka tar sands oil-from Ontario, Canada, to Indiana ruptured into Talmadge Creek, a tributary of the Kalamazoo River, on July 26, 2010. The size of the spill was initially reported to be 877,000 gallons. But in 2012, the EPA said that cleanup crews recovered 1.1 million gallons of oil and 200,000 cubic yards of oil-contaminated sediment and debris. Three years after the spill, an oil sheen remained on the river, according to The New York Times. Enbridge, the Alberta-based energy company that owned the ruptured pipeline, was fined $3.7 million by the U.S. Pipeline and Hazardous Materials Safety Administration for the incident. The cost of the oil spill has been estimated to exceed $1 billion. Enbridge now wants to build a pipeline transporting tar sands oil through a pristine boreal forest in Western Canada.

Bonga Oil Field, Nigeria
On Dec. 21, 2011, Royal Dutch Shell’s Bonga oil field in Nigeria leaked 1.24 million gallons of oil into the Niger Delta. The Guardian reported that satellite watchdog organization Skytruth posted photos indicating that the spill was 43.5 miles long and covered 356 square miles. Nigerian activist organization Environmental Rights Action told the newspaper that it did not believe Shell’s 1.24-million-gallon claim, saying that the “company consistently under reports the amounts.” Ever year Shell and other companies spill the equivalent of the Exxon Valdez tanker capacity into the Niger Delta.

Lac-Mégantic, Quebec
A 72-car freight train operated by the Montreal, Maine and Atlantic Railway derailed July 6, 2013, in the town of Lac-Mégantic, Quebec, killing 47 people and spilling 1.5 million gallons of oil. Half the city’s downtown area was destroyed by a subsequent blast. The spill leaked into the Chaudière River, a waterway that flows to the St. Lawrence River. It took crews 36 hours to extinguish the fires. The cleanup has involved siphoning oil from the river and removing more than 25,000 cubic meters of toxic soil. The rebuilding effort will cost an estimated $200 million. A criminal investigation by the Quebec police is ongoing. 2013 was the worst year ever for oil spills from trains in North America.

Guarapiche River, Venezuela
On Feb. 4, 2012 a ruptured pipeline operated by Venezuela’s state-owned oil company PDVSA spilled crude oil into the Guarapiche River, near Maturin. While government officials said they could not determine how much was spilled, one lawmaker (from an opposition party to the government) told media that 1.86 million gallons were spilled. Environment Minister Alejandro Hitcher said that the country had deployed 1,500 workers to clean up the spill. A PDVSA executive later told the state-run news agency AVN that “a good percentage” had been cleaned up, Reuters reported.

Yellow Sea, China
After a pipeline heading to a port in Dalian, China, ruptured on July 16, 2010, the Chinese government said that 461,790 gallons had spilled into the Yellow Sea. But two weeks after the spill, Rick Steiner, a former academic conservationist with the University of Alaska, said that after touring the area, he estimated the volume spilled to be between 18.47 and 27.70 million gallons. That figure, he told The Associated Press, was “at least as large as the official estimate of the Exxon Valdez disaster.” Steiner toured the spill area as a consultant for Greenpeace China, The World Post reported. He calculated his estimates based on his understanding that a 27.7-million-gallon oil storage tanker that had been reportedly filled was destroyed during the incident.
