Finally, there’s a problem with fragmentation of responsibility: Deepwater Horizon was BP’s operation. But BP leased the platform from Transocean, and Halliburton was doing the deepwater work when the blowout occurred. “Each of these organizations has fundamentally different goals,” Bea said. “BP wants access to hydrocarbon resources that feed their refinery and distribution network. Halliburton provides oil field services. Transocean drives drill rigs, kind of like taxicabs. Each has different operating processes.”
