The Ozymandias was a ship under the commission of Bysshe Energy Partners, a subsidiary of The Bysshe Company. The vessel was sent to the Point Lookout region to survey natural gas deposits. It was scuttled by Dr. Martin J. Roach, a Bysshe employee posing as an intern. Bysshe was using the Ozymandias to scout the Point Lookout area for viable signs of bio-gas, a potent energy source. The lead geologist, Caroline Saunders, was considered by Bysshe to be dangerous, as she was a "known liberal with academic ties".
The bio-gas was, in reality, formed from methane emissions from decayed corpses. Ms. Saunders, should she figure this out, would ruin Bysshe's chances at profit. They had her under watch, with Dr. Roach reporting back. Eventually, she contacted her academic ties, and Roach was forced to enact Code Blue, running the Ozymandias aground. The ship's wreckage can be seen just off the coast.
The interior is partially filled with water and is tilted from the inside. There are some junk items, along with other miscellaneous items, and at the top right of the ship there's a safe and a terminal to open it (only able to open by completion of the An Antique Land quest).
It is unknown why Ozymandias used the "USS" prefix, given that it is reserved for U.S. Navy vessels, while the Ozymandias was a private research ship. It is possible that the ship is a former navy vessel purchased for use as a private research ship.
As the areas around the cots are irradiated, it is not possible to sleep on them.
The name is a reference to the poem "Ozymandias" by Percy Bysshe Shelley, to whom the Bysshe company similarly references. The poem, its first line being "I met a traveler from an antique land" describes the transient and vainglorious nature of man's hubris, and can be seen as referencing both the Vault Dweller and the entire Fallout universe.
