ABSTRACT:
A submarine well drilling and geological exploration station includes an inner pressure hull specially configured for submerged drilling and exploration and an outer fairing hull of conventional submarine design. The pressure hull is divided by an air lock into an atmospheric pressure chamber and a superatmospheric pressure chamber. Ballast tanks are arranged so that the station may be rotated from a horizontal in-transit orientation to a vertical drilling and exploration orientation. The superatmospheric chamber permits exploration and drilling operations therein in the vertical orientation. A tandem propeller system is used to stabilize the station in position while in the vertical orientation and to propel the station from location to location while submerged in the horizontal orientation.
