A transfer system includes a conduit, a support, and a conveyor. The conduit has a first end and a second end and is configured to transfer dry material from the first end to the second end. The support is in contact with at least a portion of the conduit and is configured to maintain the second end of the conduit in a desired position relative to the first end of the conduit during transfer of the dry material from the first end to the second end. The conveyor is adjacent to the conduit and is configured to deliver the dry material to the first end of the conduit from a floating vessel configured to transport the dry material.

Proppant transfer system

A drilling rig includes a tower, a stabilizer for lifting/lowering an injector and BOP stack, and a powered arm adapted to manipulate BHA segments. The tower includes a plurality of interlocking modules and is mounted on two perpendicularly aligned skids. The tower is also provided with an opening that enables the side loading of equipment. The preferred rig includes one module adapted to support a stabilizer that includes hydraulic lifts that can raise the injector and BOP stack off the wellhead. The stabilizer also accommodates the thermal expansion of the BOP stack by rising and lowering the stack during well servicing operations. The powered arm attaches to the tower and includes an articulated gripper for manipulating the bottom hole assembly segments. Preferably, the powered arm is controlled by a general-purpose computer that guides the powered arm through a predetermined sweep.
