What's the average lifespan of an oil rig

I’ve been digging into various statistics about oil rigs and their operations lately. It seems like the average lifespan of a rig can vary widely depending on maintenance, but I’ve seen reports stating they usually last around 20 to 30 years. Has anyone come across more detailed data on how much operational downtime impacts this lifespan? I’m curious about the correlation between efficiency and longevity in the field?

And it’s interesting how maintenance schedules can really affect overall lifespan. I’ve seen rigs that last over 30 years with consistent upkeep and upgrades. While downtime definitely plays a role, optimizing maintenance windows and using predictive analytics can make a huge difference.
