The wiki says the pump needs only power and somewhere to store oil, and that it can stop now and then even when the oil containers are not full.

Keep the oil line closed from pump to tank: one player found that an open hose end anywhere on the line spills the oil into the sea. Open ports on connectors do not leak.

What is the best Black Vein setup?
Players run it one of two ways: pump the crude oil into tanks on your boat and refine it somewhere else, or put a Distillation Tower up on the rig itself and pipe the diesel and petrol down to the boat.

Why does the Distillation Tower stop?
The tower makes far more diesel than petrol, about 10 to 1 by two players’ counts, and stops as soon as either side is full. Give both outputs enough tanks, or unplug the side you have too much of.

Both diesel and petrol outlets need somewhere for their output to go. If either side fills up, the Distillation Tower stops; check both output connections and their available storage.

How do you power the station?
The wiki recommends building at least one Medium Battery and a Solar Panel on the rig, because the elevator draws a lot of power.

One player runs power cables straight down the lift, fixing the connectors to its metal back and bending the cable away from the lift at the top and bottom.

Locked Room and Hidden Room
How do you open the locked room at Black Vein Station?
One room on the main level stays locked even when the whole station is powered. Get in from below: go down the stairs at the side of that building into the small rooms underneath and climb up through a hole in the ceiling.
