Control Station ENCLAVE

Control Station ENCLAVE also known as Enclave main base, Presidential Rig, and Poseidon Energy oil rig served as the primary headquarters of the Enclave.

Background
The Poseidon Energy oil rig was a pre-War deep sea drilling platform, built over the world's last accessible underwater oil deposit in the Pacific Ocean, 175 miles off the coast of California. The United States won the international race to establish a platform at the location in January 2073, after which the Chinese accused the US of sabotage. The oil deposit was originally thought to be unreachable, due to it being located thousands of feet below the seabed.

In March 2077, the risk of nuclear confrontation resulted in the president of the United States and other members of the Enclave retreating to various fortified areas around the globe, one of which was the oil rig. The oil rig received schematics for X-01 power armor and vertibirds from the Whitespring Congressional Bunker. The oil rig served as the main base and connected to other Enclave facilities via PoseidoNet.

Inhabitants
According to Dr. Curling, there were approximately 1,000 inhabitants on the oil rig. The inhabitants were pale due to the lack of natural sunlight, but otherwise healthy. Evening entertainment consisted of various safety movies.

Citizens wore blue and yellow jumpsuits, identical in design to those of Vault-Tec shelter inhabitants, and carried no weaponry. Members of the science division wore lab coats and carried personal defense weapons such as Wattz 1000 laser pistols, while the military and Secret Service used T-51b power armor and Gauss rifles.

Equipment
The computer unit used on the Enclave oil rig was a DataPlex 2000 SmarTerminal. Vault-Tek operating systems were used on the platform as well as software such as Fenestra '98 and Apricot OS. The oil rig was powered by a Vault-Tec nuclear reactor. Scientific equipment included infrared spectrometers and gear for synthesizing compounds.

As a military base, the oil rig was heavily defended. The rig also had a significant transport vertibird fleet. Apart from Enclave soldiers outfitted with advanced power armor, security turrets and sentry robots were present. Security drills were conducted frequently.

The Chosen One traveled there via an oil tanker to save their tribe and the previous inhabitants of Vault 13, as well as to stop the Enclave and President Richardson from releasing FEV Curling-13 into the world's jet streams, killing all humans outside the Enclave. The Chosen One, aided by Marcus and others recruited to his cause, destroyed the oil rig by overloading its primary reactor. Enclave survivors never learned the truth behind the rig's destruction.

Dock
The entrance to the rig, a large dock illuminated with yellow spotlights. Every arriving vessel docks here, and the PMV Valdez is no exception.

Entry hall
The entrance hall is defended by auto-turrets. The main hall's floor has a small access terminal in the lower left corner. The hall connects via a spiral staircase to the detention/R&D level and the barracks, via a passageway with a waiting room. The final battle with Frank Horrigan is fought here.

Barracks
Connected to the entrance hall, the barracks area housed a storeroom, where T-51b power armors were used instead of forklifts, troop housing, a large gym, lavatories, an armory stocked with explosives, the admin section for the soldiers and their CO's living quarters. A spiral staircase sealed behind flood doors connected to the presidential level.

Detention and research level
Houses the prison cells used to contain the Arroyo villagers and the people kidnapped from Vault 13. Also contains several small labs and medical facilities, and storage areas. It is located south of the entry hall and connects to the trap room.

Access corridor


A series of small rooms with computer-controlled doors and an electrified floor. Unless the right combination of computers are accessed, the doors will trap those attempting. Two small side rooms provide storage and an escape route from the traps. A GECK can be found here in the northeastern room in the left survival locker in the back Survival Gear room. It is south of the detention level and connects to the presidential level.

Presidential level
Home of the offices of President Dick Richardson, Vice-President Bird, and Richardson's secretary. It also contains a bomb, a war room, a conference room, and medical facilities where testing on the FEV is conducted. A rear staircase connects it to the reactor level, and an emergency stairwell connects it to the detention level.

Doctor Charles Curling has his office at the northwestern end. Talking to him gives an opportunity for the Chosen One to convince him that humans on the mainland are part of the same species as the Enclave, potentially triggering a crisis of conscience that leads him to dump FEV Curling-13 into the ventilation that will kill off all non-protected personnel within 30 minutes. He will inoculate the Chosen One and use an aerosol inoculation on the imprisoned tribe members and vault dwellers so that they aren't affected.

Reactor level
The deepest level of the rig, houses the central computer, the rig's power generators, a small barracks and several scientists and citizens to maintain the former two. It is only accessible by a staircase on the presidential level.

Appearances
Control Station ENCLAVE appears in Fallout 2, and is mentioned in Fallout: New Vegas, Fallout 4, and Fallout 76.

Behind the scenes

 * According to Chris Avellone, the number of permanent residents on the oil rig was between 60 and 80.
 * The exact coordinates provided by the central computer for Navarro in-game place the oil rig 135 miles inland, between Fresno and Mariposa, California, in a small pond in Raymond, California.
 * The oil rig is mentioned in the Fallout Bible.
