The father of one of the 11 drilling rig workers killed in the Deepwater Horizon explosion in the Gulf of Mexico in 2010 tells a federal judge that British oil giant BP should be forced to pay at least $45 billion to resolve manslaughter and other criminal charges stemming from the disaster.

The figure is 10 times what the company agreed to pay under a deal with the U.S. government to resolve criminal charges as well as related Securities and Exchange Commission charges.
