WASHINGTON (AP) - A BP executive says BP will learn from its failed attempts to stop the Gulf oil spill and apply those lessons to its next try.

BP managing director Robert Dudley says unmanned submarines working a mile below the surface of the Gulf of Mexico will try to saw through a leaking pipe and then cap it with a funnel-like device built to capture the oil.

This next attempt will be similar to a containment dome that failed to work. Dudley says BP will try to pump warm sea water down the pipe to keep the oil and gas warmer and prevent ice from forming. That was blamed for the earlier failure.

Dudley spoke on "Fox News Sunday" with later appearances on CNN's "State of the Union," ABC's "This Week," NBC's "Meet the Press" and CBS' "Face the Nation."
