As a result of the 2010 explosion of the semi-submersible '' Deepwater Horizon '' drilling rig and the subsequent oil spill , informants within BP came forward with allegations that safety practices at '' Atlantis PQ '' were flawed . Specifically , allegations have been laid against the plans and specs used in its construction , maintenance , and operation . Kenneth Abbott , a former BP contractor , reported that up to 80 percent of the engineering plans used to build and operate the installations were never authenticated by even BP engineers for safety and stability , and that over 80 percent of the plans for the underwater welds were never verified . Food & Water Watch , a US-based consumer interest group , filed a complaint with the US district court requesting an injunction to stop production on '' Atlantis PQ '' until these matters have been investigated
