Until 2010, everyone referred to them as BP, but after the Macondo disaster Obama consistently called them "British Petroleum" so as to distance his administration from any responsibility for regulatory failure despite the fact that BP America does not operate under any British regulatory regimes or follow any British engineering standards.
The name "British Petroleum" has now stuck, but you rarely saw it before 2010.
Of course BP were culpable for the Macondo disaster as operator but it was fascinating to see the US government protect the regulator from any possible challenge or insight into how this could have happened. It will happen again and we will be shocked next time too.
This is interesting. I've only ever seen it referred to as the "Deepwater Horizon" spill/disaster. It's the differentiation between the rig and the location/prospect. I wonder if that was also tied to a deliberate communications choice.
Like Norways flagship Statoil change to Equinor.
Limp greenwashing
That would be BTUs - British Thermal Units ;)
