Abstract: Method and apparatus are provided for replacing a conductor pipe beneath a platform and providing a slot for drilling an additional well. The original conductor pipe is cut off to form a stub at a selected distance above or below the sea floor. Apparatus including a jet sub is assembled and lowered on drill pipe within a replacement conductor pipe. Fluid is pumped down the drill pipe to force the replacement conductor pipe in a selected direction around the top of the stub of the original conductor pipe so as to allow the replacement conductor pipe to pass alongside the top of the stub. An instrument may be lowered down the drill string to determine the direction of the fluid jet and the deflection of the replacement pipe from vertical. An offset tool is provided to assist in bypassing the stub with the replacement pipe. The replacement pipe may then be driven to a selected depth.

Abstract: A template that can be used for drilling subsea wells in proximity at the seafloor is provided. The template is first placed over an existing protuberance above the seafloor, which is usually the conductor casing of an existing well. The template has a plurality of cans or guide slots, of which one has a J-slot that can be engaged by a running tool. The template is placed near the seafloor and plates are released to rest on the seafloor and support the template. After wells are drilled through the slots, the template can be rotated or moved to additional well casings for the drilling of additional wells.

Abstract: A protective covering for subsea well apparatus is provided. The covering is generally a pyramidal structure and includes blades at the corners extending below the base of the structure. The blades are sized to prevent snaring of objects dragged over the covering. The covering may be assembled from sections after transport over a public highway. Methods for transporting and installing the covering and achieving penetration of the blades into the seafloor are also provided.

Abstract: Apparatus and method are provided for applying a force to a movable subsea member to move it into a preferred location for joining to a fixed member while the location of the movable member is monitored. Nozzles in the device are placed in the direction such that fluid exiting the nozzles creates a force so as to move the movable member into the preferred location. Fluid is pumped through the device and out through one or more nozzles. An environmental conductor may be tied back from a subsea wellhead using the apparatus and method by observing the location of the conductor over the subsea wellhead using a remotely operated vehicle (ROV) while fluid is pumped at the pressure and rate so as to move the conductor into position over the wellhead and lowering the conductor into the wellhead.
