In response to each of the incidents BP carried out their own independent investigations which were lead by BP senior managers with appropriate experience based at other BP sites throughout the world. BP followed in-house procedures which required an investigation of incidents of this nature to be carried out and followed internal guidelines for nature and scope of the investigations.
Additional expertise was draughted into the investigation teams either from within the BP organisation or externally if appropriate expertise was not available within (for example an independent specialist in condensation induced water hammer was contracted to provide specialist advice in the MP steam main rupture incident).
Although the focus of the BP incident investigations was different from that of the HSE investigations there was close cooperation between the incident investigation teams and a sharing of information. There was generally a close agreement between the findings of the different investigation teams.
In response to the findings of the BP incident investigation teams the Complex carried out the following actions for each of the incidents.Power distribution failure
BP operating teams conducted appropriate risk assessments before re-establishing power circuits and re-starting plants;
BP set up a new Power Systems team, responsible for power generation, power distribution and power systems development across the whole of the Complex. The work was previously carried out by a number of separate groups.
