Software change management on modern drilling rigs must go beyond ‘checking the box’

As an industry, managing software has long been a peripheral concern in rig operations. However, as new rigs with increasingly complex control systems are delivered, effective software change management is critical in avoiding downtime. Software is ubiquitous on modern rigs, controlling everything from dynamic positioning to ram activation and drilling automation. Software regression, malware and cyber-attacks are critical issues that cause NPT and could lead to an LTI or an HSE incident.

Rig injury spurs collaborative development of elevator strap for pipe laydown operations

The oil and gas industry has a history of collaboration between organizations, including operators, contractors, manufacturers and distributors, in efforts to continuously improve efficiency and safety. Incidents are often triggers that lead to this type of collaboration. This article highlights an example where an incident led to a drilling contractor, manufacturer and distributor to work together to design, produce and put in place a tool that will greatly reduce the chances of similar incidents reoccurring and, thus, improve safety on the job. The incident occurred in April on a Sidewinder Drilling rig in Oklahoma during a routine operation. It was 9:30 p.m., and the crews were pulling out of the hole and laying down drill pipe at the end of the well. The drill pipe elevators were fitted with a piece of rope approximately 3 ft in length for the purpose of tripping the elevators open. There were scattered thunderstorms at the time with gusty winds and occasional rain and hail. The rig is equipped with a top drive with a link tilt system and a hydraulic catwalk machine.
