Depends on their use, offshore oil, pilot transfers for example are just as constrained in their operations as any jet.
So how does that work with off-shore fuel requirements? Do you always plan to carry the fuel to return to a land base or only if the platform requires an alternate? Are there times when the weather at the land base just makes it impossible to depart with the fuel requirements and payload?
On another point there have been instances of QF aircraft autolanding at PH and SY because they had no fuel to go anywhere else. I don't recall the crew being "punished".
