🛢️ Offshore Oil Rigs

Oil rigs out in the open sea, an oil terminal on your coast and the ships between them: shuttle tankers bring the crude oil ashore, a supply ship takes the rigs their construction materials.

Three oil rigs on oil fields under the sea, from a jack-up rig to a megaplatform with twin derricks pumping 1,600 crude oil a minute, and deep-sea oil rigs in 8 levels that need no oil field at all, paid for with Unity every month like the game's world map mines.

🛢️ Oil rigs (on an oil field under the sea)

• 🏗️ Oil rig (I): a jack-up drilling rig on three lattice legs, 400 crude oil a minute
• 🏭 Oil production platform (II): process modules, a flare boom, a helideck and two cranes, 800 a minute
• 🔥 Oil megaplatform (III): twin derricks and a bigger flare, 1,600 a minute
• ⬆️ Upgrade in place: each tier upgrades the one before, on the same spot

🌊 Deep-sea oil rigs (no oil field needed)

• 📈 8 levels as in-place upgrades: from 100 up to 1,600 crude oil a minute (level 8 = the megaplatform)
• 💜 Costs Unity every month (0.6 per level), listed with the world map mines; in a month without enough Unity it stands still
• 🎨 The rig models in steel blue and navy instead of yellow and oxide red
• 💰 Expensive to build and upgrade, so a real oil field stays the better deal

🚢 The terminal and its ships

• 🏝️ Oil terminal: a tank farm on the coast with a long jetty, crude oil comes out at port X
• ⛴️ Two shuttle tankers (4,000 oil each) fetch the oil from the rig that has stored the most and pump it ashore
• 🏗️ A supply ship brings the rigs their construction materials from your storages (trucks can't drive out to sea) and brings back what a rig torn down leaves
• 🖱️ Click the ships like vehicles: their window shows the cargo, the trip and why they wait
• 📊 Rig window with the oil stored for the tankers, what its construction still lacks and the ships serving it

How to start

1. Research Offshore drilling (after Heavy oil cracking and Cargo depot).
2. Build an Oil terminal on the coast: the tank farm on land, the jetty out into deep water. Connect a pipe to its port X.
3. Build an Oil rig (I) on an oil field under the sea, or, after the research Deep-sea drilling (after Oil production platforms), a Deep-sea oil rig anywhere in deep sea.
4. The supply ship brings the construction materials; once the rig works, the tankers bring its oil ashore.

Good to know

• 🌍 Speaks all 21 languages of the game.
• Oil rigs (I-III) can only be built where the map has an oil field under the sea; most maps have none, the deep-sea rig works everywhere.
• Levels 5-8 of the deep-sea rig need the research Deep-sea production (after Oil megaplatforms).
• The supply ship does not deliver to a rig whose construction is paused.
• Can be added to existing saves, but not removed once you have built rigs or a terminal.
• Made for Captain of Industry 0.8.7.
