MIAMI -- After being hammered for a year over the Gulf of Mexico oil spill, BP is going on the offensive with multibillion-dollar lawsuits seeking to shift at least part of the blame to those who owned the ill-fated rig or designed a failed safety device or supplied cement that didn't hold.
Those companies -- Transocean, Cameron International and Halliburton -- each filed lawsuits of their own, and it will now be up to the courts to divvy up fault.
BP, which has rebounded remarkably in the year since the April 20, 2010, disaster, will face an uphill battle in trying to shed the albatross of the Gulf oil spill. The lawsuits filed late Wednesday were likely just opening salvos in what's expected to become lengthy negotiations over assigning responsibility and, more importantly, liability. And experts said the companies in the end will most likely reach deals to divide the responsibility and costs.
