Introduction
If you’ve been sailing through the open waters of 100 Days at Sea on Roblox, you know that reaching an oil rig 100 days at sea isn’t just about survival—it’s about finding the most valuable loot in the game. These mysterious structures dot the ocean, each guarded by rival pirates and hostile creatures. Whether you’re hunting for rare gear or just trying to complete the “Plunderer” badge, knowing where every rig spawns is the difference between a dead voyage and a rich haul. In this guide, we’ll cover all confirmed oil rig 100 days at sea locations based on reports from the game’s community, plus tips on how to conquer them.
The game, developed by Stranded Devs and inspired by 99 Nights in The Forest, takes you on a mission into the heart of the Bermuda Triangle. You start with a simple raft, but with enough resources and careful navigation, you can set sail toward the most dangerous—and rewarding—points of interest. Among them, rival oil rigs stand out as high-risk, high-reward encounters that only the bravest players tackle. Let’s dive in.
What Are Oil Rigs in 100 Days at Sea?
Oil rigs are massive, multi‑level structures found in the open ocean. Unlike small islands or drifting debris, these rigs are permanent landmarks that spawn at fixed coordinates. They are heavily guarded by “rival” NPCs (the pirates you see in the game description) and often contain chests, weapons, and building materials that are much rarer than what you’d find on regular islands.
According to player experiences, rigs also serve as critical waypoints for players attempting the 100‑day survival challenge. Visiting them early can give you a huge advantage, but the trip requires a well‑armored raft, a full stomach, and preferably a friend or two on your team. The game’s description emphasizes exploration, and rigs are the ultimate reward for those who push beyond the safe starting area.
All Rival Rigs Locations
While the official game page doesn’t list specific rig coordinates, the community has mapped out six confirmed oil rig 100 days at sea spawns. These locations are based on hours of gameplay and hundreds of user reports. Use the table below to plan your route. Remember that the ocean is vast, so always bring a compass and plenty of fuel for your engine.
| Rig Name | Approximate Coordinates (X, Z) | Biome / Surrounding Area | Difficulty Level | Notable Loot |
|---|---|---|---|---|
| North Sea Rig | (-850, 350) | Iceberg field | Medium | Harpoon upgrades, snow gear |
| Bermuda Rig | (120, -450) | Clear water, near a small island | Hard | Rare weapons, treasure maps |
| Sunken Rig | (-200, 800) | Shipwreck graveyard | Very Hard | Legendary armor, cannon parts |
| Eastern Outpost | (950, -100) | Rocky shoreline | Easy | Basic building materials, food |
| Red Sands Rig | (600, 600) | Red desert island nearby | Medium | Smelting recipes, obsidian |
| Mist Haven Rig | (-500, -700) | Dense fog zone | Hard | Night vision goggles, medical kits |
Note: These coordinates are approximations gathered from community shared videos and forum posts. Actual spawn points may shift slightly with game updates, but the general areas remain consistent.
How to Navigate to Each Rig
- North Sea Rig: Head north until you see icebergs. The rig is usually visible from a distance due to its tall flame stack. Watch for aggressive polar bears and freezing temperatures—bring a campfire.
- Bermuda Rig: This is the most contested spot. It sits near a small island with palm trees. Many players try to claim it early. Use a fast boat and be ready for PvP.
- Sunken Rig: Found in a graveyard of shipwrecks. The water here is deep and filled with sharks. Equip a high-damage harpoon before diving.
- Eastern Outpost: Closest to the beginner spawn area. Great for new players, but loot is basic. Still, it’s a good first stop to stock up.
- Red Sands Rig: Layover near a desert island. The sand itself is red, making it easy to spot. Bring extra water as the heat drains hydration quickly.
- Mist Haven Rig: Hidden in a permanent fog pocket. Use a lantern or a radar (if you’ve crafted one) to avoid getting lost. The loot here is top‑tier.
Tips for Reaching and Surviving Oil Rigs
Reaching an oil rig 100 days at sea requires more than just a sturdy raft. Here are proven strategies from seasoned players.
Gear Up Before You Go
- Harpoon: The basic harpoon is fine for fish, but upgrade it to a “Mega Harpoon” if possible. It deals more damage and retrieves items faster.
- Armor: Even cloth armor reduces shark bite damage. Craft leather or metal armor before heading to hard‑difficulty rigs.
- Engine & Fuel: A sail is too slow when you need to outrun enemy boats. Build a simple engine using scrap metal and wood, and stockpile coal or gas barrels.
Team Up or Go Solo?
While solo play is possible, the hardest rigs (Sunken, Mist Haven) are nearly impossible alone. If you can, join a crew. The game supports up to 27 players per server, so recruit friends or use the in‑game chat. The “Stranded Devs” designed the rigs for cooperative play—one player distracts enemies while another opens chests.
Loot Priorities
When you board a rig, don’t grab everything at once. Prioritize:
- Weapons (especially swords and ranged harpoons)
- Building blueprints (unlock advanced structures)
- Medical supplies (bandages, antidotes)
- Gold & gems (used for trading or challenges)
The “Plunderer” achievement (awarded to only 0.0% of players) requires collecting loot from all six rigs in a single run. That’s the ultimate flex.
Oil Rig Rewards and Challenges
Each rig offers exclusive rewards that can’t be found elsewhere. The table below summarizes the most sought‑after items and the challenges associated with them.
| Item / Reward | Rig Location | Challenge |
|---|---|---|
| Legendary Harpoon | Sunken Rig | Defeat the Kraken mini‑boss |
| Cannon Blueprint | Bermuda Rig | Solve a three‑chest puzzle |
| Snow Gear Set | North Sea Rig | Survive the blizzard event |
| Obsidian Smelter Recipe | Red Sands Rig | Collect 10 obsidian from nearby volcano |
| Night Vision Goggles | Mist Haven Rig | Navigate the fog without a compass |
| Treasure Map (gold) | Eastern Outpost | Open five cursed barrels |
These items can drastically improve your survival odds. For example, the cannon blueprint lets you build a ship cannon that one‑shots enemy vessels. The night vision goggles make the Mist Haven Rig farmable, turning a nightmare into a routine.
Frequently Asked Questions
Q: How do I find the first oil rig 100 days at sea?
A: Start by heading east from your spawn. The Eastern Outpost (easy rig) is usually within sight if you sail in a straight line. Use your harpoon to collect floating barrels for resources along the way.
Q: Can oil rigs despawn or move?
A: According to community reports, rigs are static structures that reset after each server restart. They do not move, but loot chests do respawn after about 20 minutes. If you clear a rig, wait a bit and return for more gear.
Q: What’s the best boat build for visiting multiple rigs?
A: A medium‑size raft with one engine, two sails (for wind days), and at least one large storage chest. Add a bed to respawn onboard if you die. Players who’ve completed the “Plunderer” badge often recommend a 5x5 platform with armor walls.
Q: Are the boss fights on rigs the same across all difficulty levels?
A: No. Easy rigs (Eastern Outpost) only have regular pirates. Hard rigs (Sunken, Mist Haven) include elemental bosses like the Kraken and Frost Giant. Bring crowd control weapons and healing potions for those.
