The new moratorium applies to any deep-water floating drilling facility but is not based on the water depth where drilling occurs. It will end by 30 November or sooner.The new moratorium applies to any deep-water floating drilling facility but is not based on the water depth where drilling occurs.

"The measurements that will be taken during this test will provide valuable information about the condition of the well below the sea level and help determine whether or not it is possible to shut the well for a period of time," Adm Allen said in a statement."The measurements that will be taken during this test will provide valuable information about the condition of the well below the sea level and help determine whether or not it is possible to shut the well for a period of time," Adm Allen said in a statement.
During testing, the system collecting the leaking oil will be shut down for six to 48 hours while pressure readings are taken to make sure there are no other leaks from the well.During testing, the system collecting the leaking oil will be shut down for six to 48 hours while pressure readings are taken to make sure there are no other leaks from the well.
NEW CAP FOR LEAKING OIL WELL
In June, BP placed a cap, known as an LMRP cap, over the top of the Deepwater Horizon well so oil could be siphoned to the surface. The company has now replaced this with a tightly fitting version - a sealing cap.
NEW CAP FOR LEAKING OIL WELL
On 10 July engineers removed the LMRP cap, meaning oil began to freely leak from the top of the blowout preventer once more, although the Q4000 containment system continued to take some oil to the surface.
NEW CAP FOR LEAKING OIL WELL
Engineers have now bolted a new capping stack onto the blowout preventer (BOP). Valves inside the stack are being closed to test whether, as hoped, it will shut off the flow of oil completely.

BP has also hooked up a floating riser pipe to the Helix Producer ship to provide a further route to the surface for oil. However, both this and the Q4000 systems are being suspended while the tests are carried out.

Engineers have now bolted a new capping stack onto the blowout preventer (BOP). A series of tests will be conducted to see if the flow of oil can be stopped using the newly installed equipment.
NEW CAP FOR LEAKING OIL WELL
During the test the three ram capping stack will be closed and all sub-sea containment systems that are siphoning off oil will be temporarily suspended, effectively shutting the well.
