Thank you, Mr. Chairman.
The whole concept of the blowout preventers is to act as a well barrier. It's intended to be one of at least two well barriers that must be in place at all times. The primary well barrier while drilling is in fact the drilling fluid itself, which prevents oil and gas from flowing into the well and keeps the well under control. The BOP stack is routinely tested—function-tested, pressure-tested—in accordance with established standards, so this instance in the Gulf of Mexico is not the first time that a BOP has ever been used or activated. These BOPs come into play throughout the operation of a well, and are routinely function-tested and pressure-tested.
In fact, one of the elements we routinely do, and one of the elements we are going to focus extensively on in respect of the current operations with the Stena Carron, is to provide extensive oversight of that testing, including the blowout preventer itself, as well as the acoustic control system and the ROV intervention system. We're going to have witnesses on board the installation to oversee those activities, including a representative of the certifying authority, and we will examine those records and tests to ensure that they meet prescribed standards. We intend to bring a level of oversight to this operation over and above what is normally exercised.
Thank you.
