Rust Oil Rig Guide 2026: Large vs Small, Every Timer

Updated 31 Oct 2026 Source Cross-checked against whenisforcewiperust.com Large Oil Rig and Oil Rig guide pages (level layout, timers, camera codes, myth corrections, Power Trip Dome pump update of 6 Aug 2026), frozen-rust.com Small and Large Oil Rig monument pages (scientist counts, keycards, recycler status, solo feasibility), rust-survival.com monuments guide (card ladder, heavy scientist behaviour, recycler economy). Note: sources disagree on whether Small Oil Rig has an on-site recycler — flagged in the text rather than resolved, since it has changed across patches. By

The oil rigs are the highest-value PvE loot runs in Rust — and the most contested. Both rigs share the same loop: get there by boat or heli, clear the scientists, hack the locked crate, survive the Chinook that answers it, then get out with the loot before the sirens bring every neighbouring team to your position.

They have also been in the game since 2019, which means a great deal of rig advice has been copied forward without ever being checked. This guide separates what actually happens from what guides keep repeating.

Large vs Small: which rig should you run?

Large Oil RigSmall Oil Rig

Heavy scientists on hack10–12Heavy response by Chinook

Best forTeams of 3+Solo / duo

The locked crate loot pool is the same on both rigs. That is the key fact most players miss: the Large Rig only pays more because of the extra elite and military crates. A duo should usually take the Small Rig instead.

Source disagreement, flagged deliberately: frozen-rust.com lists a recycler on the Small Oil Rig (and none on Large); whenisforcewiperust.com states neither rig has a recycler and attributes the confusion to the research table on Level 6 of Large. We have not resolved this ourselves — it has plausibly changed across patches. Check in game before you rely on it, and plan to carry components home either way.

The run, step by step

  1. Get there. RHIB, rowboat, minicopter or scrap heli. The Large Rig also has a moonpool under the structure (added April 2024) that lets you dock below the waterline and climb a tube to Level 3 with no scientists in it — and it slips past the boat patrol.
  2. Clear the scientists first. Work upward using container cover. Do not start the hack until the deck is clear.
  3. Swipe your cards. On Large: green at Level 3, blue at Level 4, red at Level 6. On Small: a single blue card opens the military-crate room and the hackable crate. All cards are optional extra loot — none of them are needed to hack the crate.
  4. Hack the crate. Hold E. A fixed 15-minute timer starts, sirens sound, and a Chinook drops heavy scientists on the helipad.
  5. Hold low, not the helipad. The heavies land on top and sweep it first. Let them come down to you, and funnel them through a single doorway rather than fighting in the open.
  6. Loot and leave. Grab the crate at 0:00, plus military and elite crates and scientist drops.

Every timer that matters

TimerDurationWhy it matters
Scientist respawn~24 minReturn whether you are there or not — ruins your exit
Normal crates~30–36 minStandard container respawn
Card room crates~65 minTied to the puzzle reset, not the crate timer
Locked crate hack15 minFixed, cannot be sped up or extended
Full rig reset~30 minAfter the last player leaves the area
Anti-camping radiation~45 min after hackOnly once the crate has been looted

The 24-minute scientist respawn is the one that catches people. Hack the crate, spend fifteen minutes hiding, and the scientists you killed on the way up are back before it opens. Your entrance is not your exit.

The crude oil pump to the Dome

Since the Power Trip update (6 August 2026), the rigs are tied to the Dome. Once someone gets the Power Plant to phase 3, the switch inside the Large Oil Rig red card room comes alive. Flip it and the Dome pumps crude for 20 minutes.

Rig switchCrude output
Large Oil Rig~3,000 (full rate)
Small Oil Rig~1,500
Both together~4,500

You cannot pick the crude up by hand. You need a modular car with a tanker module, a hose tool to connect it to the pump, and a car lift to unload it. The October 2026 update also added a short delay before the oil starts flowing after the switch is flipped. Refine it at a refinery at the fixed 1 crude → 3 low grade ratio.

Six myths guides keep repeating

ClaimReality
“Bring an electric fuse”Neither rig needs one. Both are permanently powered and every locked door is a card reader.
“Swipe a red card to hack the crate”The locked crate needs no card at all. The red card opens a separate room next to it.
“Large Rig has a recycler on Level 4”Neither rig has one. The research table on Level 6 of Large is the likely source of the mix-up.
“You need a hazmat for the radiation”There is no radiation during a run. Anti-camping rads start ~45 minutes after a hack, once the crate is looted.
“Other players can extend your timer”They cannot. Player input stopped affecting the countdown.
“You can craft at the Level 3 workbench”The tier 2 bench on the Large Rig is a prop. It does nothing.

Common mistakes that lose rigs

  • Hacking the crate the moment you arrive. Clear, loot the card rooms, then start the timer — otherwise you fight heavies and the patrol at once with a full inventory.
  • Parking at the dock. It is the first place anyone checks. Tuck the boat under the structure.
  • Fighting heavies in the open on the top deck. Every one of them shoots you at once. Take a stairwell.
  • Bringing every card but no meds. Cards are worthless if you die on Level 2.
  • Assuming the rig is empty because it is quiet. A team that already hacked the crate is deliberately silent, waiting out the same fifteen minutes you are.
  • Standing under the Chinook. It touches down on the helipad. Be somewhere else.
  • Planning to recycle on site. Assume there is no recycler. Bring bag space, not optimism.

Heavy scientists are not regular NPCs

They wear far more armour — surviving multiple body hits and demanding several headshots to kill (roughly five versus three for a normal scientist) — and they carry powerful weapons including the M249. Treat them like kitted players: take cover, fight from angles, prioritise headshots. Their drops are the real reason to contest the rigs: rocket launchers, night vision goggles and high-tier medical and weapon loot.

Frequently asked questions

Do you need a keycard to hack the oil rig locked crate?

No. The locked crate on both rigs needs no keycard, no fuse and no puzzle — you hold E and a 15-minute timer starts. Keycards are only for the separate green, blue and red loot rooms elsewhere on the rig.

Do you need an electric fuse for the oil rig?

No. Neither rig requires an electric fuse — both are permanently powered and every locked door on them is a card reader. Guides that tell you to bring a fuse are applying mainland monument rules that do not apply offshore.

How long is the oil rig crate timer?

15 minutes on both rigs, and it is fixed — neither you nor other players can speed it up or extend it. Player input stopped affecting the countdown a long time ago.

How many scientists are on each oil rig?

Small Oil Rig has about 12 patrol scientists, plus heavy scientists dropped by Chinook when you hack the crate. Large Oil Rig has 23 patrol scientists, 10–12 heavy scientists on the hack, 2 elite crates and 8 military crates. A clean Large run is north of 400 scrap; Small is roughly 300+ scrap.

How often do oil rig scientists respawn?

About 24 minutes — and they come back whether you are still there or not. This is the timer that catches people: if you hack the crate and then spend fifteen minutes hiding, the scientists you cleared on the way up are back before the crate opens, and your clean escape route down the stairs is not clean any more.

Is there radiation on the oil rig?

Not during a run. Neither rig has radiation while you loot, so you do not need a hazmat suit or radiation pills. The only rads are an anti-camping measure: about 45 minutes after the crate hack starts, and only once the crate has been looted, radiation ramps up across the rig so campers have to leave. Wear real armour instead.

Can you solo the oil rig?

Small Oil Rig, yes — about a dozen scientists plus the heavy-scientist response is doable solo with a decent rifle, armour and meds. Large Oil Rig is tough but possible for a skilled player; a duo or trio is far safer. If you are learning, start Small.

What CCTV codes work on the Large Oil Rig?

OILRIG2DOCK, OILRIG2HELI, OILRIG2EXHAUST, OILRIG2L1, OILRIG2L2, OILRIG2L3A, OILRIG2L3B, OILRIG2L4, OILRIG2L5, OILRIG2L6A, OILRIG2L6B, OILRIG2L6C, OILRIG2L6D. The codes are the same on every server. Check OILRIG2DOCK and OILRIG2HELI before you burn fuel getting out there.
