LONDON — The British oil company BP said Friday that Cameron International, one of its contractors in the oil well that burst last year in the Gulf of Mexico, had agreed to pay $250 million to settle claims related to the ensuing spill.

Cameron, based in Houston, designed and manufactured the so-called blowout preventer on the drilling rig, which failed to stop the oil from spilling. The settlement, which is BP’s fourth so far with companies that worked on some parts of the well, was not an admission of liability by either party, BP said.

The “settlement allows BP and Cameron to put our legal issues behind us and move forward to improve safety in the drilling industry,” Robert W. Dudley, the BP chief executive, said in the company’s statement. “Unfortunately, other companies persist in refusing to accept responsibility for their roles in the accident and for contributing to restoration efforts.”

BP had already agreed to similar settlements with Anadarko Petroleum; a unit of Mitsui Oil Exploration, MOEX, which had stakes in the well; and Weatherford International, which made a part of the well. Those settlements totaled about $5.1 billion.
