a plurality of extendable fluid lines arranged on the extendable frame and configured for fluid coupling between a utility plant and a drill rig; an expandable and retractable electrical system configured for electrically coupling a utility plant to a drill rig; and a ground engaging portion configured for over-the-road transport of the module. ### Claim 2 (depends on 1) The utility umbilical module of claim 1, wherein the plurality of extendable fluid lines comprises a plurality of telescoping lines. ### Claim 3 (depends on 1) The utility umbilical module of claim 1, wherein the plurality of extendable fluid lines includes a high-pressure drill fluid line. ### Claim 4 (depends on 2) The utility umbilical module of claim 2, wherein the high-pressure drill fluid line comprises a primary portion secured to the frame and a second high-pressure portion secured to the frame with sliding brackets. ### Claim 5 (depends on 4) The utility umbilical module of claim 4, wherein the second high-pressure portion is configured for sliding into alignment with the primary portion when the frame of the module is expanded. ### Claim 6 (depends on 1) The utility umbilical module of claim 1, wherein the expandable and retractable electrical system comprises a drag chain. ### Claim 7 (depends on 1) The utility umbilical module of claim 1, wherein the ground engaging portion comprises front and rear wheel structures comprising rims and tires for highway travel. ### Claim 8 (depends on 7) The utility umbilical module of claim 7, wherein ground engaging portion comprises a front wheel structure including a pivot frame and a hitch. ### Claim 9 (depends on 1) The utility umbilical module of claim 1, wherein the expandable frame comprises a telescoping spine portion. ### Claim 10 (depends on 9) The utility umbilical module of claim 9, wherein the expandable frame comprises a rear portion having a lower cable deck and a cage and a front portion having an upper deck. ### Claim 11 (depends on 10) The utility umbilical module of claim 10, wherein the upper deck is retractable into the cage of the rear portion. ### Claim 12 (depends on 11) The utility umbilical module of claim 11, wherein the cage includes a rail and a rear end of the upper deck is guided during extension and retraction along the rail. ### Claim 13 (depends on 12) The utility umbilical module of claim 12, wherein the rail provides support to the rear end of the upper deck. ### Claim 14 A drill rig system, comprising: a utility plant; a mobile drill rig; and a utility umbilical system configured for placing the utility plant and the drill rig in electrical and fluid communication during drilling and throughout movement of the drill rig on a drilling site, the utility umbilical system, comprising: a plurality of utility umbilical modules, each module comprising: an expandable frame; a plurality of extendable fluid lines arranged on the expandable frame and configured for fluid coupling between a utility plant and a drill rig; an expandable and retractable electrical system configured for electrically coupling a utility plant to a drill rig; and a ground engaging portion configured for over-the-road transport of the module. ### Claim 15 (depends on 14) The drill rig system of claim 14, wherein the plurality of extendable fluid lines comprises a plurality of telescoping lines. ### Claim 16 (depends on 14) The drill rig system of claim 14, wherein the plurality of extendable fluid lines includes a high-pressure drill fluid line. ### Claim 17 (depends on 16) The drill rig system of claim 16, wherein the high-pressure drill fluid line comprises a primary portion secured to the frame and a second high-pressure portion secured to the frame with sliding brackets. ### Claim 18 (depends on 17) The drill rig system of claim 17, wherein the second high-pressure portion is configured for sliding into alignment with the primary portion when the frame of the module is expanded. ### Claim 19 A method of establishing a utility umbilical system, comprising: transporting a utility umbilical module having a ground engaging portion configured for over-the-road transport, by towing the utility umbilical module over the road on the ground engaging portion; electrically and fluidly coupling the utility umbilical module to a utility plant and to a drill rig; extending the utility umbilical module including extending a frame, piping, and electrical lines on the module. ### Claim 20 (depends on 19) The method of claim 19, wherein extending the piping comprises telescopically extending the piping.
