Preventing control systems software-related root causes from being overlooked or misdiagnosed streamlines operations. Given that 57% of lost-time injuries occur on the rig floor and drilling control system software manages 75% to 95% of the movement and operation of drill floor equipment, it is clear that software needs to be addressed on today's high-specification assets. Due to the industry-wide shortage of software-experienced personnel, however, many drilling contractors and operators do not have enough in-house knowledge to be able to identify all potential software-related failure modes or conduct thorough root cause analyses. Consequently, when equipment failures occur on high-specification drilling assets, control systems-related issues can be overlooked as potential root causes. The safety and reliability of systems can be improved through incident investigations that identify and address both software- and hardware-related issues.
