Negative learning by doing is very easy to explain: as you go, you realise many perils and dangers of this thing that you were not aware of in the beginning, and those result in a lot of safety precautions added in subsequent projects, increasing the costs.

I can't imagine how TCO will not be much lower for subsequent ones, though.

Redundancy generally costs more to maintain not less.

Aka design 1 has 500 pumps, design 2 has 600 and is safer but now there’s more equipment to main and more complex plumbing etc.

I begin to understand the logic behind the US derailings.

The idea here is that maintenance is much, much cheaper than rescue operations. If 100 more pumps let you run for years without a scram, go along and order them.

[Retric]

That assumes it’s actually a benefit.

The point here is the “100 pumps” raise costs and complexity for zero benefit.
