Sadly, this doesn't seem like a lot, to be honest. Especially, for all the downsides a smaller ship has,

- giraffe_lady 4y agoI think 50 years is at the longer side of ship lifetime but not especially an outlier. The big commissioning fleets sell them after a couple decades and replace them with new. The secondhand owner refits for a different purpose or partially overhaul then runs it for another couple decades. Sometimes a third owner gets some use out of it. They normally go at least 35 years before total decommissioning though, usually longer.
- smorrebrod 4y agoIt depends on ship type. For example methane carriers are expected to hit 40 years of lifetime while some low-end bulk carriers are scrapped after only 15 years.
