Apparently, there were a lot of false alarms. They apparently were annoying and woke up sleeping workers. That’s what a chief technician for Transocean, the company that ran the oil rig, said about the reasons that safety systems were knowingly turned off – which helped lead to the disaster that killed 11 people and caused the ocean to flood with oil. In other oil-company-friendly news, BP got transparent about their Photoshopped images and posted a set of images up on Flickr – the ‘chopped images and the originals. Which is funny, because none of the images needed any Photoshopping at all. source
