и что здесь long-distance line?

Выражение встречается в следующем контексте:

In default of pressure boosting compressor station and the high kick-off pressure in the
long-distance line, only limited production could take place between 1979 and 1981. Subsequently, the decreased pressure in the long-distance line allowed for larger seasonal production from the reservoirs.
