Oil giant BP has decided to postpone the final plugging of its blown out oil well in the Gulf of Mexico.
Meanwhile, Transocean, the company which owns the Deepwater Horizon rig that exploded on April 20th, alleges BP is withholding evidence about events leading to what's said to be the worst oil spill in history.
Oil major BP has decided to hold off putting the final plug in its blown out Gulf of Mexico Macondo oil well until September according to the top U.S. government official overseeing the spill cleanup.
Coast Guard Admiral Thad Allen says this revised date for completion has been made to allow a critical piece of seabed equipment to be replaced.
Meanwhile BP is testing the pressure in the well and the seabed equipment already installed.
The company's senior vice president, Kent Wells, said the test should confirm whether or not the cement and seal beneath the blowout preventer will hold during the 24 hour period it will take to install the new seabed equipment.
Meanwhile, Swiss-based Transocean Ltd, which owned the Deepwater Horizon rig that exploded on April 20 has alleged that BP is with-holding evidence about actions that led to the worst offshore oil spill in history.
One which scientists say has left a plume of hydrocarbons 3,000 feet beneath the Gulf's surface, and which could be there for some time.
BP refutes Transocean's claim and says it has cooperated with ongoing federal investigations.
In a further development, Maersk Oil, the petroleum arm of Danish shipping firm A.P Moller-Maersk, is interested in purchasing BP assets the international oil major decides to spin off - so long as they have potential to generate profit.
