RE: How much power is enough?

The engines that get 10s of thousands of hours are on a very strict maintenance program because their longevity directly affects the operator's bottom line.
Also, engines are not created equal. One would hope that an operator selects an engine that is designed and suited for the type of work it will do. So the little diesels that are running the refrigeration systems on trucks and railroad cars are designed with this kind of 24/7, constant speed operation in mind. There are a lot of engines that would not hold up for the required length of time under this same application, so it would be dumb to try to use one of them.

Actually, running something like a compressor system is pretty easy on an engine. The load doesn't vary all that much, the rpms are constant, and the hours are predictable with relation to the strict maintenance programs John mentions. In fact, this is what the Ford Dorset engine that was later marinized into the FL120 proved to be ideal for. It was terrible in its intended application as a truck engine because it was underpowered and did not hold up under the constantly varying high loads and higher rpms of highway use. But it proved to be an ideal engine at lower load and constant rpm applications like pumps, generators, cranes, and other industrial and agricultural uses. Which is what made it ideal (at the time) for marine applications.
