10 maggio 2010 - dopo il fallito tentativo dello scorso weekend and waiting for the well vent (relief well) is completed (we are talking about weeks or even months of excavation), BP asks for help in finding new ways to stem the leakage of crude oil. The ideas are varied, but the question is, will be effective or feasible? We see the main options:
-a second attempt to halt the main hole will be made mid-week by BP, using a smaller dome. After the failure of the last few days confidence in the success of the operation is weak;
-an 'other option involves cutting the exhaust duct (riser pipe) and its replacement with a larger one in order to bring the oil to a ship surface: it is risky, because in bankruptcy the escape of crude oil could increase;
-an 'other option is to cover the cement and mud blowout preventer (BOP) to stop the loss: the operation (known as "top kill") would require 2-3 weeks;
-as reported by the U.S. Coast Guard, a plan, currently under analysis, are even sending waste high pressure (mainly shredded tires) to the wellhead damaged in an attempt to clog the hole.
During the day there will be a summit at the White House with President Obama to do il punto della situazione.

10 maggio 2010 - la mappa, elaborata dal GOHSEP, mostra la probabile estensione della marea nera per mercoledì 12 maggio. Mentre gli esperti cercano soluzioni per arrestare la fuoriuscita di petrolio, l'estensione della macchia continua a crescere e un impatto con vaste aree costiere sembra ormai inevitabile. Cosa succederà se non si riuscirà ad arrestare le perdite o se le condizioni meteorologiche, fin'ora favorevoli, cambieranno improvvisamente? La stagione degli uragani si avvicina e il disastro della DeepWater Horizon rischia di diventare la più grande catastrofe ambientale che gli Stati Uniti (e forse il Mondo) abbiano mai conosciuto. Il 5 maggio l'Ammiraglio della Guardia Costiera americana Thad Allen ha dichiarato che "al momento una stima esatta" delle perdite "è probabilmente impossibile". Da quella data il NOAA e la Guardia Costiera hanno smesso di fornire dati. Tuttavia, considerando la capacità produttiva della DeepWater, la quantità di greggio riversata in mare ogni giorno potrebbe superare i 25000 barili (circa 4 milioni di litri). © GOHSEP - Tutti i diritti riservati
10 maggio 2010 - un elicottero Black Hawk si prepara a scaricare sacchi di sabbia a Elmer's Island, nel tentativo di creare una diga artificiale. Gli sforzi disperati to contain the advance of the spot crude oil continues unabated. After receiving the approval of the EPA, BP has paid directly at the loss by using an underwater vehicle, an unknown amount of dispersing chemical compounds whose effects on the marine ecosystem in recent days have raised a heated debate.
To stop the oil before it reaches the coast , to the Florida police have suggested that along the front of the oil barges filled with hay and compressors to shoot the water, so do the crude aggregate and remove pollutants more easily.
A product chemical called Gladiator, made up largely of silicon, could represent an effective barrier against the advance of oil, especially in areas difficult to access. According to Graham Strachan, Director of Aquatain Products Pty Ltd, Gladiator, used in strategic places, could push the oil through the formation of a surface film and concentrated in such a way as to facilitate their collection. In addition, he says, silicones are safe for the environment, as in a few days break down into silicate compounds common in the crust and the thin film does not interfere with the activities of birds and other aquatic creatures.
E' al vaglio delle autorità federali e dello stato della Louisiana il progetto, annunciato dal governatore Bobby Jindal, di creare un anello di isole artificiali per proteggere le coste. Secondo il quotidiano Washington Post il piano, che le autorità contano di sottoporre alla Casa Bianca entro pochi giorni, prevede la costruzione di un cordone di isole lungo circa 110 chilometri, ottenuto dragando sabbia e fango dal fondale marino e depositando il materiale lungo le coste esterne delle isole della Louisiana.

11 maggio 2010 - continua la disputa per trovare i responsabili dell'incidente. During a hearing at the Congress leaders of the three involved companies (BP, which owns the platform - the Transocean, maker of the platform - Halliburton, a provider of services for the oil industry) have played the blame game by pointing the finger against a another. Lamar McKay, BP America president, has insisted that the platform and the blowout preventer failed were owned by Transocean.
Steven Newman, president and CEO of Transocean, testified that his team was playing only the directives of the BP and that in any case was a failure of Halliburton.
Halliburton is accused of causing the accident during an oil well cementing in place 20 hours before the fire. Tim Probert, Security Officer of Halliburton, of course, has denied claims by ensuring that all operations were performed in a workmanlike manner and in accordance with applicable federal and oil industry and stressed that at the time of the disaster was just the Transocean, which was carrying out operations on the platform.
According to legal experts is only a matter of time before the Justice Department to initiate criminal investigation.

12 maggio 2010 - un portavoce della BP ha dichiarato che la seconda cupola di contenimento, conosciuta come "top hat" (cappello a cilindro), è arrivata sul luogo del disastro. Le operazioni di posizionamento dovrebbero iniziare nella giornata di giovedì e concludersi entro the end of the week. © BP - All rights reserved
May 12, 2010 - President Obama in recent days (here in a photo taken in Venice, Louisiana, May 2) said want to raise the roof of responsibility for the BP, since cleanup costs have already exceeded the current threshold. BP said Monday that it has already spent $ 350 million to remedy the disaster, about 17.5 million dollars a day, and have paid 295 claims received on 4700. The costs are destined to rise and is a major blow for BP, but as it affects really on the budget of the colossus? Since the beginning of the oil giant made profits estimated at $ 93 million per day: 4 days of profits would then be sufficient to offset the costs incurred so far.
BP probably will survive the crisis without major damage in the long term.

12 maggio 2010 - scavando nel passato recente della BP continuano ad emergere torbide verità: indagini insabbiate, violazioni volontarie della sicurezza, una politica orientata a contenere gli effetti degli incidenti anziché prevenirli (costa meno), etc. Nel 2005, dopo l'esplosione della raffineria a Texas City che costò la vita a 15 persone, l'EPA avviò un'indagine volta a colpire i vertici dell'azienda, ritenuti guilty of knowingly ignored security lapses. The investigation was stopped by the Justice Department and BP solved his troubles by paying a penalty of $ 50 million for violating the Clean Air Act The weight of the BP obtained after years of lobbying, and the familiarity of the Washington with its leaders have allowed the oil giant to survive any crisis, "too big to fail" is the most apt definition for BP, which among its largest customers last year, has the Pentagon. © Miami Herald - All rights reserved

May 12, 2010 - investigations into the cause of the accident are becoming more intricate. Henry Waxman, a Democratic member of Congress, said that the blowout preventer was a loss to a primary hydraulic system a few hours before the disaster and has failed a pressure test. The government engineer in charge of giving approval to the mining operations has admitted that he never required performance tests the device. An informant also revealed that the oil industry has long been that the tests carried out in blowout preventer are invalidated. Mike Mason, who has worked on oil rigs in Alaska for 18 years, claims to have observed cheating in tests at least 100 times, in many wells owned by BP and with company representatives present: providing falsified reports seem almost routine .
The administration has meanwhile decided to reorganize the Mineral Management Service (MMS), the government agency that oversees offshore drilling, is suspected of too close to the oil industry. The Secretary Interior Ken Salazar said that the agency will be divided in two, separating the inspection function to the platforms that oversight of contracts and collection of royalties.

May 13, 2010 - between the various options that technicians and engineers are studying to limit the leakage of oil, if the attempt with the new dome fails, there is the insertion of a tube in the pipe damaged (called "Insertion Riser Tube") to bring the oil to a surface ship support. Other proposals are under consideration on the table for experts. In an article published yesterday in the Russian newspaper Pravda Komsomoloskaya it was suggested, as a last resort disaster, to use an atomic bomb. Controlled nuclear explosion, a technique used for 5 times in Soviet times (including 4 with success - but never under water), may seal the leak, crumbling rocks around the well.

May 14, 2010 - A satellite photo shows that, over time, the extension of the oil spill is growing more and more. After making a series of tests and have analyzed the data, EPA and NOAA scientists approved, for the first time, the use of chemical dispersants directly into the depths of the sea to prevent the oil from reaching the surface. The news immediately provoked bitter reactions to the possible harm that chemicals might have on the marine ecosystem. The Coast Guard Rear Admiral Mary Landry, however, ruled that although have been tested, the chemical dispersants have not yet been used. CSTARS © - All rights reserved
May 14, 2010 - on Thursday, Jon Pack BP spokesman said that the attempt to position the new dome, called "top hat", will end in a few days or (more likely) next week and no later than this weekend, as previously announced. Today has now begun the operation called "Riser Tube Insertion: via remote-controlled underwater robot engineers are trying to put in these hours of the end of a 1500 meter long pipe in the pipe damaged. If the operation should have the results hoped for, like a straw sucking the oil in a vessel and collecting on the surface, the tube could reduce the overall loss of 75%. © Deepwater Horizon Response - All rights reserved
May 14, 2010 - President Obama angrily and harshly criticized the "ridiculous show" offered by the leaders of BP, Transocean and Halliburton to Congress. "It 's clear that the system has failed," he said. "It has failed badly." The President promised that his administration is too close relationships between federal agencies and the oil industry will end, which shares the anger and frustration of many Americans affected by the crisis and will not rest until it is resolved.

May 15, 2010 - Dr. Erica Miller, the International Bird Rescue Research Center, and his staff clean up a brown pelican covered with oil. So far the oil spill has had a limited impact on the coasts, but scientists on the Pelican Bay have identified the depths of the huge plumes of oil, one of them long and 16 km wide and 100 meters high. "There's a shocking amount of oil in deep water," said Samantha Joye, a researcher at the University of Georgia. The phenomenon is unprecedented and of great concern among experts. Typically, the oil is dispersed only on the sea surface, but this time the phenomenon seems to affect the entire water column. In addition to being extremely toxic to marine life, the crude oil could substantially reduce the oxygen levels endangering the entire ecosystem. According to experts, there seems to be no connection between the phenomenon and the use of chemical dispersants. Greenpeace USA © 2010 - All rights reserved
May 17, 2010 - the gas that comes along with oil from the wellhead is damaged by the burning ship Discoverer Enterprise. The operation "Riser Tube Insertion" was successful, but the results are announced by BP in recent days: the system manages to contain only 20% of the estimated loss (1000 barrels per day - Approximately 160,000 liters) and President Obama said he was "unimpressed". From the day of the disaster that is the first successful attempt to reduce the extent of the leak of crude oil. According to BP spokesman in the coming days (probably early next week) we will proceed with the operation "top kill", which cemented the top of the well, the loss should stop once and for all. © U.S. Coast Guard - All rights reserved
May 24, 2010 - The oil reached the coast of Louisiana. According to the Governor Bobby Jindal more than 65 miles of coastline (105 km) have already been affected by marea nera. © Boston.com - Tutti i diritti riservati
26 maggio 2010 - "Plug the damn hole" (tappate quel maledetto buco), così Barack Obama, durante una riunione privata nello Studio Ovale, avrebbe espresso la propria frustrazione riguardante la mancanza di progressi da parte della BP nell'arginare la fuoriuscita di petrolio nel Golfo. Nella giornata di domani il Presidente dovrebbe annunciare la decisione del governo di imporre nuove e più severe norme di sicurezza e di ispezione per le operazioni estrattive offshore , mentre venerdì si recherà in visita per la seconda volta nei luoghi colpiti dal disastro. Public pressure on the administration Obama is very strong, however, only the BP has the technology and means to remedy the incident, while the federal agencies can look to limit operations to contain the oil spill. © The White House - All rights reserved
May 26, 2010 - second BP spokesman Top Kill the operation was carried out as planned. The heavy fluid in these hours are being pumped into the well should stop flow of oil, but it will take at least 24 hours to see if the method actually worked. E 'can covering the event live from this page offered by CNN. According to BP's technical chances of success are between 60 and 70%. If the operation fails it will attempt to capture the raw with the dome "Top Hat".
