Oil Rig
The Oil Rigs are a series of strongholds found across the waters of the Palpagos Islands. As of the Feybreak Update, there are three Oil Rigs.
Barge Oil Rig
The first stronghold was introduced in the Feybreak Update and can be found in the lake to the north of the Sealed Realm of the Frozen Wings waypoint. As the first oil rig encountered, it's a Lv 30 stronghold that lacks the anti-air measures that the later oil rigs have, making it safe to approach by flying Pal. However, it comes with stationary turrets that can tear through underleveled player and Pal alike. Note that these turrets come with two barrels and shoot in a straight line - meaning that they will shoot directly past a carefully moving player on either side. These turrets have a console at the base, which can be interacted with to destroy the turret.
There are three known spawn points for the big chests:
- Inside the tents on the south end of the rig.
- Behind the big Crusher next to the tall tower.
- Inside the blue shack on the west end of the rig.
They may contain a small amount of 
Crude Oil, arrows, training manuals, Skill Fruit, and Schematics.
Enemies will respawn once the player moves sufficiently out of range, whereas chests and turrets will respawn after several in-game days.
Oil Rig
The second Oil Rig stronghold can be found southeast of Marsh Island's waypoint. It was the first Oil Rig added to the game, in the Sakurajima Update, and poses a late-game challenge at Lv 55. The chests and gun turrets will respawn 30 minutes after the large chest is looted.
The Oil Rig is surrounded by anti-air laser turrets that will target players approaching on a Flying Pal. These lasers deal very high damage and can cause even high-level Pals to faint within a few seconds. They do not target swimming players or players riding a Water Pal, such as 
Azurobe or 
Surfent. Hybrid Flying/Land Pals, such as 
Shadowbeak, are also targeted by the laser turrets even if the player is not actively flying. All anti-air laser turrets can be permanently destroyed using the consoles at their base, making return trips on a flying pal much safer.
Many enemies spawn on the Oil Rig, and moving far enough away from killed enemies will cause them to respawn. There are also gun turrets that can be temporarily destroyed either by damaging them or interacting with the consoles at their base.
Without a mount, escaping the oil rig can be difficult, so bringing a 
Homeward Thundercloud or 
Dogen is useful to instantly return to the nearest player base.
Loot
There are two different types of chests found on this Oil Rig, and all have static spawn locations.
The most valuable chest can spawn in one of four preset locations (labelled with apple icons A-D). These spots are often heavily-guarded by large numbers of powerful enemies, such as the 
Syndicate Crusher. The chests may contain 50-200 Crude Oil, Large Lotuses, or end-game Schematics.
12 smaller chests (labelled with chest icons 01-12) containing other valuable loot spawn alongside the large chest. These can contain 5-20 Crude Oil, 15-20 
Dog Coin, Small Lotuses or, rarely, Schematics. Chest 06 can only be acquired with a Flying Pal, as the tower it is on top of cannot be climbed or grappled. All anti-air laser turrets should be destroyed before attempting to loot this chest.
Platform Oil Rig
The third stronghold was introduced in the Feybreak Update and can be found directly to the west of the Feybreak Shipwreck waypoint. Meant as an endgame challenge, the Platform Oil Rig comes in at Lv 60 and, in addition to the turrets and lasers from the previous strongholds, also comes with the Anti-Air platforms found across the camps on the Feybreak island.
