Transportation, storage, and installation system for rig utilities

摘要

A transportation, storage and installation device for rig utilities. The device includes a telescoping bridge having an outer frame assembly with an opening therethrough supporting a plurality of cables. The telescoping bridge also includes an inner beam assembly receivable within the outer frame assembly opening supporting a plurality of cables, wherein the inner beam assembly may be extended from or retracted into the opening. The device also includes a utility boom having an elongated post terminating in a rotatable boom base, and a boom pivotally connected to the boom base wherein the pivotal connection has an axis transverse to the post. At least one cylinder moves the boom from a storage position substantially perpendicular to the post to a position wherein the boom is at an obtuse angle to the storage position. The device also includes a service arm supporting a plurality of electrical cables. The service arm includes a hinge having an axis transverse to the service arm to permit the arm to swing radially about the axis. The device also includes a pipe trolley mechanism to store high pressure fluid lines for storage and transportation and thereafter to provide a mechanism to interconnect high pressure mud pumps to the base of the mast at the substructure.
