OCEAN 35

OCEAN 35 shares some intriguing environmental concepts: People in Maine are starting to eat invasive crabs; NYC is experimenting with old toilets to grow oysters; someone developed a thermal powered piston for controlling greenhouse ventilation and why has it taken so long to come up with edible six pack rings? You will also find breaking updates on previous articles: Bees; Hand Sanitizers and Plastic Microbeads. And we also took a closer look at the 1,000 year rainfall event in Louisiana. OCEAN is the environmental education publication of Safe Harbor Environmental Services. This newsletter is intended

Gulf Oil Leak and Safe Harbor

May 25 Update: 

The Gulf Stream Loop Current, which did pick up a tendril of oil, periodically reconfigures itself into an isolated loop. This has just happened, which means the cut off loop may have a lower probability of transmitting oil to the Gulf Stream. An updated, May 25th image is shown directly below and an earlier image is below that.

 

Gulf Oil Leak and Safe Harbor

May 14 Update:

The ambitious Republican governors of Mississippi and Louisiana are a study in contrasts as an oil spill threatens coastal economies still reeling from Hurricane Katrina.

Mississippi's Haley Barbour, a well-connected former Washington lobbyist, has calmly said the oil slick looming offshore is just a sheen in most places and there's no reason for people to panic.

Louisiana's Bobby Jindal, meanwhile, has questioned oil giant BP PLC's response capability and the federal government's plans to clean up crude spewing from a well blown out by an offshore oil rig explosion April 20. He activated the Louisiana National Guard and called on coastal parish leaders to draw up their own response plans after saying he couldn't get answers from BP or the Coast Guard.

BP and government officials have pegged the leak resulting from the Deepwater Horizon rig disaster at 5,000 barrels a day, or about 200,000 gallons. But a scientist who analyzed the video of the gushing pipe said Thursday the oil flow appeared to be much greater.

Soon after the explosion three weeks ago, the government said oil and gas were flowing from the seabed at a rate of 210,000 gallons or 5,000 barrels a day. Now, after viewing the video, some scientists calculate it at 2 million gallons a day or even higher.National Public Radio reported yesterday that there could be 10 times as much oil coming out as the previous estimate of 5,000 barrels per day. Which raises some big questions about whether BP is being honest about the size of the spill.

Safe Harbor and Gulf Oil Leak

MAY 12 UPDATE:

The committee said that there were at least "four significant problems with the blowout preventer" used on the Deepwater Horizondrill rig.

Rep. Bart Stupak, D-Mich., said that a 2001 report by Transocean, which made the device, indicated there can be as many as 260 failure possibilities in the equipment. The device is supposed to be the final safeguard against a well blowout by clamping down and sealing a gushing oil well.

About 325,000 gallons of dispersant have been used, although scientists warn it may kill marine life

A relief well is being drilled but could take many weeks

A huge steel funnel suffered a build-up of ice-like crystals and had to be put aside

They're going to take a bunch of debris, shredded up tyres, golf balls and things like that, and under very high pressure shoot it into the preventer itself and see if they can clog it up and stop the leak," he told CBS television.However, experts have warned that any further damage to the blowout preventer - a huge valve system meant to turn the oil off - could see it shooting out at 12 times the current rate.

Gulf Oil Leak and Safe Harbor

MAY 10 UPDATE:

At the site of the ruptured well a mile underwater, a remote-controlled submarine shot chemicals into the maw of the massive leak to dilute the flow, further evidence that BP expects the gusher to keep erupting into the Gulf for weeks or more.

Crews using the deep-sea robot attempted to thin the oil which is rushing up from the seabed at a pace of about 210,000 gallons per day after getting approval from the Environmental Protection Agency, BP PLC officials said.

Two previous tests were done to determine the potential impact on the environment, and the third round of spraying was to last into early Tuesday.

The EPA said the effects of the chemicals were still widely unknown.

Gulf Oil Leak and Safe Harbor

Spring, 2010 will be remembered not only because we witnessed a lifetime, environmental tragedy unfolding in what appeared to be slow motion in the Gulf of Mexico but we were also forced to witness a level of denial, misrepresentation, self protection and poorly represented science, while a major environmental resource, held in a public trust, was allowed to fall apart before our eyes.

May 1, 2010: Following these sketches you will find our rationale and after that you will find relevant links and continuing updates from the Gulf.

Safe Harbor has developed these innovative, alternative response concepts, following a phone discussion with an engineer from the Gulf of Mexico, who was seeking new ideas for dealing with the overwhelming oil spill.  These concepts were developed over a long weekend by an adhoc group, put together by Safe Harbor. Our concept addressed the request for "Alternate Response Technology" but what we really did was to look at all available, existing materials and technologies and just reconfigure them. These concepts reduce worker exposure to carcinogenic raw oil, reduce effort significantly and provide more effective collection. These conceptual sketches were executed by LEED Certified, Sustainable Architect Joy Cuming of Aline Architecture in Orleans, MA.

For some perspective, about 300 miles of coastline may be directly impacted. The Gulf coastline north of the spill area, stretches more than 800 miles. If the prevailing, seasonal southerly winds continue, much of this coast may be at risk. If southwest winds blow, Florida's 300 mile Gulf Coast will additionally be at risk and IF the wind should blow from the north..the Gulf Coast of Florida may be spared but the Gulf Stream, which loops near the spill, will be impacted and transport oil first to the reefs of the Florida Keys, and then to Miami beaches, followed by the Outer Banks and on into the North Atlantic Ocean and the east coast. Mexico, Cuba and the Bahamas may eventually find this oil in their coastal ecosystems and on beaches. Most likely, with 3 different leaks now reported and a long term scenario looming, all of these things may happen. Downplaying these possibilities sort of ignores the truth of possibly a quarter million gallons, or more, being added to the equation each day.

Rationale: In the current scenario, recovery and mitigation require long term, sustainable concepts for collection. Using sustainable and passive principles, we reviewed existing technology, in place materials and available vessels. Our concept considers a reconfiguration of existing elements, which could contribute to increased remediation and reduced effort. This concept would also minimize exposure of emergency workers to carcinogens in recovered oil.

With this concept, floating oil would be delivered, by natural forces, to the collection areas, instead of collection systems chasing oil. Collection booms would be used to direct the floating oil instead of trying to encircle it. This would reduce effort and materials. Conceptual configuration can be left in place for prevailing winds and reconfigured in response to changing winds.

System # 1. Locally available barges from the Gulf Coast would be retrofitted with existing technology oil collection systems, powered by wind energy with a back up generator. Barges (see detail sketches) can operate with a high degree of automation. Collection booms (see concept sketch) can be reconfigured, utilizing wind pressure to drive surface oil to collection system passively. Pairs of barges would be anchored at the head of the crescent shaped containment booms. Collected, reclaimed oil would be stored in tanks and pumped into service tankers for further separation and industrial use ashore.

System # 2. Locally available barges from the Gulf Coast would be fitted with wind generators.  Sustainable energy would power circulation and dispersal systems for cultures of patented bioremediation bacteria. The barges would be anchored in place, with dispersal hoses between them. The bacteria would be maintained at maximum, reproductive temperature by circulation through passive solar, dark painted deck tank. Dispersal system would consist of measured release openings, along lengths of surface floating hoses, balanced by controlled intake of oil/water medium, powered by a circulation pump. This same system could be utilized, by adding 24/7 day lighting, to reintroduce indigenous phytoplankton.
