Control Station ENCLAVE

"Followers' Credo"

The Poseidon Energy Oil Rig served as the primary headquarters of the Enclave, initially as the Presidential Rig, and eventually Control Station ENCLAVE in its own records, also housing the ENCLAVE Vault-Research Control.

Officially, it was simply 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 (N 37° 17', W 124° 23' 24").

Background
The United States won the international race to establish a platform at the location in January 2073, after sabotaging Chinese efforts to do so. The oil deposit was originally thought to be unreachable, due to it being located thousands of feet below the seabed. During the nuclear storm of the Great War, the Enclave's most important members and essential personnel were evacuated to this location.

By March 2077, with the world heading directly for nuclear confrontation, the President of the United States and other members of the Enclave retreated to various fortified areas around the globe. The Poseidon Oil derrick in the Pacific Ocean was chosen as a secret base from which the USA could continue to exist and wage war on China, with the eventual goal of retaking the continental United States. Some members of the Enclave retreated to remote locations in other parts of the world, but when the bombs hit, they lost all contact with the main group. As the world burned and United States disintegrated, its president and the Enclave, remnants of the pre-War American shadow government, Fallout 3 Official Game Guide Game of the Year Edition, page 48: "THE ENCLAVE In the recent past, the Enclave—the remains of the United States government—were evacuated to an oil rig off the coast of California. Little is known about what happened to these forces, although the country has [sic] new commander-in-ch ief  [sic]: President John Henry Eden. However, recent reports and chatter have pinpointed the resurgence of the Enclave, with their base centered on a secure underground facility known as Raven Rock. Initial contact was made there 35 years ago. ''During this time, the new President Eden has been slowly rebuilding his resources, thanks in part to the technology already available at the Raven Rock military base. Vertibirds, weapons, and robots were easy to construct, but human followers were more difficult to find. The answer was to rely on Colonel Autumn, who controls the Enclave soldier forces, as well as creating a propaganda-spewing series of Eyebots sent to roam the Wasteland, spreading hope. Eden could spout his pro-government rhetoric, and promise a return of the pre-war America of legend: a land of white picket fences, baseball, apple pie, and good, old-fashioned American global supremacy.'' ''President Eden's secretive plan all along has been to rule over an America of the "pure," free from any mutation. He has learned of a ridiculously ambitious experiment known as Project Purity, and knew the time to strike had come: His Enclave forces would "reclaim" the Jefferson Memorial. By controlling the purified water, Eden would control the Capital Wasteland, and the rest of the country eventually. What better way to administer modified F.E.V.- which kills anyone infected with any form of mutation-than through the water supply?"'' established themselves as its continuation, claiming authority over the United States mainland.

In late 2077, not long before the Great War, the oil rig received schematics for X-01 power armor and Vertibirds from the Whitespring Congressional Bunker.

In 2242, the Chosen One traveled there via an oil tanker to save his 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 worldwide, in preparation for Enclave's colonization. The Chosen One (aided by Marcus and others recruited to his cause) destroyed the oil rig by overloading its primary reactor and causing a megaton-sized thermonuclear explosion. Enclave survivors never learned the truth behind the rig's destruction.

Overview
The oil rig was, in fact, a disguised, powerful military base with industrial facilities, top notch medical technology, completely self-sufficient and able to provide the Enclave with a power base. Not only was it their main base, it was connected to other Enclave, military and corporate facilities via PoseidoNet (it seems the oil rig's PoseidoNet software was a trial version, ending in 2079).

The usual computer unit used on the Enclave oil rig was a DataPlex 2000 SmarTerminal. Operating systems used on the platform included Fenestra '98, Apricot OS, and Vault-Tec proprietary OS.

Power
The oil rig was powered by a Vault-Tec uranium-based nuclear reactor. The entire process was automated, thanks to a supercomputer running recently invented synchronized multi-processors on a tri-processor motherboard, which carefully regulated coolant temperature, intake of seawater for cooling, expending hot water and waste from it, as well as regulating the neutron bombardment on the uranium fuel rods. Seawater was pumped from 500 meters depth, used both to move the turbines and cool the core. Radiated water and miscellaneous toxic byproducts of the operation were disposed of off through a waste conduit, terminating one mile south of the rig, causing irreversible ecological damage to coasts of southern California and Mexico. The biggest flaw in the system was that even the slightest disruption in the supercomputer's operations would lead to a 100 kiloton nuclear explosion within two hours, due to an uncontrolled bombardment of the uranium isotopes. The loss of power would also severely cripple the oil rig, as energy intensive systems would shut down (force fields, for example) and watertight doors would close, to prevent any flooding. Additionally, manually retracting the containment rods would trigger the same reaction, with no hope of restoring control, as putting them down to slow down the reaction would overheat the reactor.

Defenses
As a military base, the oil rig was heavily defended, including external guns to protect against seaborne threats (i.e. everything without a Poseidon IFF transponder). The rig also had a significant transport Vertibird fleet. Internally, apart from Enclave soldiers outfitted with advanced power armor, an extensive network of security turrets (dual .223 caliber miniguns) and sentry robots was present, ready to neutralize any foe. Quite probably, the oil rig was the single most well protected location in the entirety of post-nuclear America.

Industrial and scientific facilities
The oil rig's scientific facilities were outfitted with cutting edge pre-War technology. Equipment present in them included infrared spectrometers and gear for synthesizing compounds - in vast quantities, if need be.

Inhabitants
By 2242, the Enclave expanded its operations to the mainland; the number of permanent residents on the oil rig was between 60 and 80. Taking into account non-permanent residents, the Enclave oil rig was home to between a hundred and as many as a thousand inhabitants.

All inhabitants tended to be pale, due to the lack of natural sunlight. However, they were of good health. Their position in society could be easily determined by their gear. Regular citizens off duty typically wore jumpsuits derived from Vault-Tec designs and didn't carry any weapons. Personnel on duty were usually the science staff (wearing white lab coats and carrying standard issue energy sidearms for personal defense), while soldiers wore power armor and various high end weapons. Lower rank troops stationed on the rig typically wore last generation T-51 power armor and carried M72 Gauss rifles, whereas higher ranking soldiers and members of the Secret Service used advanced power armor and various high end weapons. Finally, the president and vice-president could be easily identified by their pre-War suits and lack of armaments, save for access cards giving them control over the entire Enclave.

Security drills were a regular feature of life on the oil rig. Evening entertainment usually consisted of various safety movies.

Layout
The massive structure of the oil rig probably had many facilities for industrial manufacturing, research and development, Vertibird maintenance, etc. Only a small portion of the Oil Rig is represented in the game. The schematic below shows the area flow. Once the reactor is sabotaged, a special evacuation stairwell opens from the presidential level to the barracks (represented below by a dotted line), while access to detention/research and the access corridor is sealed off.

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 of the rig, lined with powerful auto-turrets that are designed to obliterate everything and everyone foolish enough to attempt an attack on the installation. The main hall's floor is a massive relief with the word Enclave stamped on it, with 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 (together with a large gym and 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 from Vault 13. Also contains several small labs and medical facilities, and storage areas. It is located south from 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 the unfortunate explorer and leave them at the mercy of the floors. Two small side rooms provide storage and a reprieve 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, Richardson's secretary and the Enclave's other elite. It also contains a bomb, a war room, a conference room and medical facilities where testing on the FEV is being done. A rear staircase connects it to the reactor level, and an emergency stairwell connects it to the detention level.

Colonel 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 dumping FEV Curling-13 into the ventilation that will kill off all non-protected personnel (i.e. civilians and scientists, except for named characters) within 30 minutes, allowing the player to loot them with impunity. He will inoculate the Chosen One and use an aerosolized inoculation on the imprisoned tribesmen and Vault dwellers, so that they aren't affected.

Reactor level
The deepest level of the rig, it 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
The Enclave Oil Rig appears in Fallout 2, and is mentioned in Fallout: New Vegas, Fallout 4, Fallout 76, its update Steel Dawn, and the Fallout 3 Official Game Guide.
