Rules to Disaster versus Insisting on Skin in the Game

Rules Aims to Prevent Offshore Rig Disasters is a reaction to the "Deepwater Horizon" rig explosion of 2010 which begs the question what rule was missing that would have prevented the rig's manager from short cutting safety to meet a schedule?  Currently it's the loss of $50 Billion of BP's shareholder value that prevents BP and other Major Oil Companies from risking disaster.  The article doesn't mention whether the $75 million liability cap on offshore drilling companies is still in place but if it is then good luck trying to get a really limited LLC to clean up a mess similar to BP"s rig explosion.
