🛢️ Oil Pumps Expanded

Your oil pumps grow with your industry: upgrade them in place to Oil pump II and Oil pump III, no tearing down, no new pipes.

Oil pump II pumps 3 times as much crude oil as the vanilla oil pump (60 / min), Oil pump III with its twin pump jacks 6 times as much (120 / min, twice Oil pump II), on the same 5 x 3 tiles, from the same oil deposit.

Features

  • ⬆️ Upgrades in place: select an oil pump and press Upgrade. It keeps its place, its pipe and its oil deposit; the game delivers the cost difference like for any other upgrade
  • 🛢️ Oil pump II: the game's own pump jack, 1.2 times as big
  • 🛢️🛢️ Oil pump III: two of the game's pump jacks, 1.35 times as big (bigger than Oil pump II), side by side, working half a stroke apart
  • 🎞️ Animated like the vanilla oil pump, while the pump works; the icons are the game's icon, drawn bigger for II and twice for III
  • ⚡ Power: 80 kW → 240 kW → 480 kW, the same power per barrel as the vanilla pump
  • 👷 Workers: 2 for Oil pump II, 3 for Oil pump III
  • 🧱 Costs: Oil pump II takes construction parts II, Oil pump III construction parts III and steel
  • 🔬 Research: two new nodes in the research tree, right after the research they need
  • 🔊 Sound: the vanilla oil pump sound

Oil pump III: two big pump jacks, half a stroke apart

How to start

  1. Research Oil pump II (after Advanced diesel).
  2. Select one of your oil pumps and press Upgrade.
  3. Research Oil pump III (after Oil pump II and Construction III) and upgrade again.

Good to know

  • 🌍 Speaks all 21 languages of the game.
  • A deposit runs dry faster: an Oil pump III empties it 6 times as fast as the vanilla pump.
  • Can be added to existing saves, but not removed once you have built an Oil pump II or III.
  • Made for Captain of Industry 0.8.7.

The models and icons are made from the game's own oil pump while the game runs. No game files included. Contains Harmony 2.4.2 (MIT licence).
