The energy industry continues to pore over the shake-up to BP’s safety division, which was announced yesterday, just two days before Bob Dudley takes over as chief executive.

Several, including our energy editor Sylvia Pfeifer, point out Dudley’s focus on safety is hardly revolutionary – Tony Hayward made very similar noises when he took over. Over at Fuel Fix, however, they point to a happier precedent – Exxon’s largely successful attempts to improve its record following the Exxon-Valdez accident.
