Pasco County Utilities recently tied a record for the longest pullback or length of pipe-line pulled underground on an installation with AMERICAN Ductile Iron Pipes 36-in. Flex-Ring pipe, which was 1,640 ft in length. By Charlie Ingram34 FUSING PIPE IN FLORIDAThis project in the Florida Keys called for a 17-mile transmission system buried along U.S. 1 and a 5,218-ft pipeline was pulled 60 ft under the ocean oor to connect Summerland Key to Ramrod Key. By Susan Hylton36 DCI CONTINUES TO CAPITALIZE ON MARKET POTENTIAL FOR HDD LOCATINGSeattle is perhaps synonymous with innovative companies that display ingenuity in engineering technology. So it is tting that Digital Control Inc., an industry leader in electronic guidance tracking for horizontal directional drilling, is headquartered just south of Seattle in Kent, Wash.By Andrew Farr 40 HDD IN CALIFORNIAThe job began as a relatively straightforward directionally drilled creek crossing to install 600 ft of steel gas pipe. However, a change in the size of pipe, unexpected site restrictions, difcult soil conditions, and limited hours to work made this project far from routine.

The response has been phenomenal! WelovethattheHDDmarketcontinuestotakeholdofand expandintonewmarkets. Andwelovebringingyouthestories within the HDD market, showcasing interesting projects, products and trends in one compact and jam-packed book.Last winter was definitely cruel, with record subzero temperatures andsnowfallputtingmostofNorth Americainanicyvicegripfor the better part of the season, resulting in a slower-than-normal start to the first quarter of the 2014 construction season. But expectations remain high for a strong finish for the year.The HDD market has been on an upward trajectory for the last several years, with a huge catalyst being the oil and gas market. Its all about the pipelines. In 2014, oil and gas continue to be huge drivers of HDD work, with manufacturers working in overdrive to meet the needs of HDD contractors pursuing these projects. The Marcellus and Utica shale plays in New York, Ohio, Pennsylvania and West Virginia, as well as the Bakken shale play in Montana and North Dakota, are providing fertile and profitable ground for HDD contractors. For insightful perspective from manufacturers and contractors, check out assistant editor Mike Kezdis look at todays HDD market, beginning on pg. 12.AsinpastHDDGuides,webringyouinterestingcasestudiesthathighlightdifferent applications of HDD and the different technologies used in those projects. We also have a feature written by associate editor Andrew Farr on the evolution of Digital Control Inc., the industry leader in electronic guidance tracking for the HDD market. Andrew spoke with DCI co-founder John Mercer, who recounts the companys early beginnings and discusses how locating technology has changed over the years. Its a great read that starts on pg. 36.Our HDD Guide wouldnt be complete without two sections: Products Showcase and Drilling Rig Specs. They are both here and bigger than ever. The response to our call for HDD products resulted in an expanded section to present them all to you awesome!

If you need a new rig, this is the place to start!Finally, a sign that the HDD market is on the rise is the number of HDD educational op-portunities. In 2013, we organized an HDD Seminar in Las Vegas the first the industry has had in some time. In 2015, we are teaming with Arizona State Universitys Del E. Webb School of Construction to host the 2015 Horizontal Directional Drilling Academy, a two-day intensive course designed to equip attendees with knowledge of HDD pre-construction, design and ma-terial selection, construction and operations. The seminar covers everything from drilling flu-ids to locating to HDD contracts. Through case studies and industry experts, this conference is a must for HDD contractors! Mark your calendars for Feb. 19-20, 2015, in Tempe, Ariz., for this excellent educational opportunity.

Matthesen points to the numerous gas pipeline hits in recent years, such as the line explosion in San Bruno, Calif., which has developed a renewed focus on pipe-lineintegrityandtheimportanceof damage prevention in the HDD industry.HDD was not created to ll a need. It was created to ll a desire to provide an alternativemethodology.Newinnova-tions are sporadic and largely a surprise comingfrominnovativepeople.They willhappenandtheindustryneedsto be ready to use them, Halderman said. HDD was created by innovators. It still needs that attitude more than ever.This focus on inspection, repair and replacement, also holds true in the mu-nicipal and utility world. As the econo-my turns around, the industry insiders see money coming available for much-needed infrastructure improvements. This potential for growth is not sole-ly in the United States, or North Amer-icaasawhole, Wisniewskipointedto countriesacrosstheglobe.Fromal-ready urbanized locations where infra-structure needs improvement to devel-opingcountrieswhereinfrastructure has yet to be installed.Iamstillverybullishonthefu-tureoftrenchless, Wisniewskisaid.

Well, that is aside from Alice in Chains, Starbucks, a lot of rain, a big Space Needle and the reigning Super Bowl champion Seahawks.But it is tting that Digital Control Inc. (DCI), an industry lead-er in electronic guidance tracking for horizontal directional drill-ing (HDD), is headquartered just south of Seattle in Kent, Wash. The area is closely linked with companies such as Microsoft and Boeing, neither of which are slouches in the engineering depart-ment,andDCI,inaway,combineselementsfromboththose companies. As it happens, DCI has its roots in aviation and its the companyscontinuouspushinsoftwareengineeringforHDD locating that has kept it at the forefront of the market. DCI continues to innovate with new products continuously underdevelopment,sayscompanyco-founderJohnMercer. One reason we are able to do this is that we have a rich pool of talented people to choose from in the Seattle area. Seattle has spawned many startups and has produced, as well as attracted well-trained people to the area. After 23 years in business, DCI is continuing to guide the in-dustry into the next era of groundbreaking directional drilling projects by doing what it does best developing technology that makes the drilling process easier and more efcient. ROOTED IN AVIATION: PRE-DCIDigitalControlsproductshavealwaysbeenbasedoncon-cepts taken from aviation, which can be traced back to the way Mercerandco-founderPeterHamblingapproachedthetech-nology due to their background in ying and aeronautical engi-neering. Today, aviation terminology is still used to describe the movement and position of drill heads during HDD jobs.Mercer worked for a research company involved in aerodynamics and high-pressure water jet cutting.A different branch of the compa-ny had a contract with EPRI to an electric distribution cable replace-ment device.The device required an existing cable to hydraulically pull itself through the ground cutting a hole using high-pressure wa-ter jets.Based on the results of this contract,a new service company called FlowMole was formed to commercialize the device.In 1984, Mercer was brought into FlowMole, which wanted him to develop a separate device that could install cables with-outrequiringanexistingcable. ThedeviceMercerdeveloped wascalledtheGuideDril,whichwasthestartofthemodern HDD drills as they are now produced.Thisdevicewasanearlyhorizontaldrillframethatused keyed drill pipe to push a contoured head through the ground, says Mercer. The head was designed to contain a dipole trans-mitter that was tracked using a cable locator. The tracking op-erator held a paper that had a table relating the depth shown onthelocator,whichwascalibratedforlinelocating,tothe depth of the dipole transmitter. AccordingtoMercer,thedevicewasreallytherstofthe modernHDDtrackingsystems.In1987,Mercerreceivedthe rst ISTT No-Dig award in London on behalf of FlowMole. De-spite success in this area, his time working with FlowMole was Mercers rst introduction to drilling and he still felt unfamiliar with the industry language. FLYING HIGHDCI Continues to Capitalize onMarket Potential for HDD Locating By Andrew FarrThe Right Stuff: DCI founders John Mercer (left) and Peter Hambling with Peters World War II bomber the two often y to visit customers. If we had a business jet, we probably would not get near the attention that we do arriving in a WWII bomber, says Mercer.tti_36-39.indd 36 7/11/2014 1:34:11 PMwww.trenchlessonline.com TRENCHLESS TECHNOLOGYSPECIAL SUPPLEMENT37 Since I had not been involved in the drilling industry prior to working for FlowMole and had an aeronautical background, Ifoundthedrillingorientationtermsawkward,hesays. Ire-placed the drilling terms: tool-face angle, elevation and azimuth with the equivalent aeronautical terms: roll, pitch and yaw. These terms remain today with the HDD industry.In designing the steering head of the boring tool, I saw great similaritybetweentheearthforcesontheheadandtheaero-dynamicforcesonabodyathypersonicspeeds. Whenpeople asked why I left aerodynamics for drilling, I would say the drill-ing is really teradynamics and I saw a lot of similarity.Mercer left FlowMole in 1988 with the goal of developing a more efcient locator.While FlowMoles model had been a targeted HDD locator, the design was still based on cable locating principles. I wanted to design a locator specically for HDD,he says. The main problems with the cable locating technology were the ghost signals that often confused operators and caused cables to be in-stalledatshallowerdepthsthanspeciedandthelackofdepth accuracyastheborebecamedeeper.Ialsowantedtoeliminate the fragile keyed drill rod used to determine roll orientation and I wanted to provide the locating operator with pitch. Holding a drill level was one of the most difcult tasks to train an operator and I knew that knowing pitch would make the training go much faster.Knowing it would take more than just ideas and a basic design to model, Mercer contacted his friend Peter Hambling for help. Hambling, who has a masters degree in aeronautical engineer-ing,wasworkingatthetimeforOrbitalSciences,acompany workingonputtingcommercialsatellitesintoorbit.Hambling joinedMercerinJanuary1991andDigitalControlInc.,began selling its rst product in August of that year.TARGET STEERING AND NEWER MODELSDigitalControlsrstproductwasanimmediatesuccess asproductivityincreaseddrastically,cablelocatorsfaded fromthemarketanddigitallocatingofdrillheadsbecame the new standard. From there, the company continued to im-prove upon early models, one of which included incorporat-ing a radar screen look into a new locator, called the Eclipse. With this model, the boring tools transmitter location under-groundwasshownlikeabliponaradarscreensothatthe operator could walk directly to the target.The Eclipse paved the way for what would become a major milestoneindigitallocatingforthecompanytheintroduc-tionof TargetSteering.

With TargetSteering,theoperatorpro-gramsadesireddepthintothelocator,placesitonthebore path in front of the drill head, and the drill operator then steers directly to the desired position below the locator.Over the years, DCIs transmitters and handheld devices have continuedtoevolve.Inadditiontotransmittingthepitch,roll and depth of a drill head, transmitters are also capable of relay-ing temperature and even uid pressure. One of the companys new remote displays, the DigiTrak Auro-ra, is a remote device that includes wireless and Bluetooth con-nectionsandisthecompanysrstremotedevicetofeaturea color touchscreen interface. Continuing to advance this technol-ogy has been the hard work of longtime employees who have taken Mercer and Hamblings ideas to the next level. Introducing DCIs new products to market falls on the companys sales and marketing team, including product manager Siggi Finnsson.This device (Aurora) is specifically aimed at being exten-sible,saysFinnsson,whohasworkedatDCIfor19years. So as we come up with clever ways of displaying data dif-ferently, [information] will be delivered in forms of applica-Horizontal Directional Drilling GuideDCIs new remote display, the DigiTrak Aurora, is a 10-in. color touchscreen with wireless and Bluetooth connections.

The concept of apps and wireless delivery makes it easy for Aurora to be upgraded and evolve. Aurora also allows the user to set alarms, or threshold points, to alert an operator when the drill headhasreachedacertainpositionorwhentemperatureand pressure have reached certain levels. These alarms lower the num-ber of things a drill operator must actively monitor while on a job.KEYS TO MARKET LEADERSHIP According to Finnsson,DCI doesnt tend to think of itself as com-petingwithothermanufacturersofHDDlocatingdevicesinthe industry, but rather with the innovative technology in any industry.Although all [trenchless] companies are moving the ball for-ward, we tend to think that on this fairly narrow stage of HDD locating, we tend to do more of it than most, he says. I think that one of the key things we do differently than really anybody else,isthatwehavefocusedonlyonHDDlocating. Wedont have other products or other lines that compete with the locat-ing. So anything and everything we do from a research stand-point is focused on advancing that state of the art. Finnsson says the company also has extensive experience in its personnel, who are invaluable in helping the company solve problems and continuing to move the business into the future. Being in Seattle, we also have access to some exceedingly well-qualied engineers, he says.There are ex-Microsoft people at DCI, there are ex-Boeing people at DCI. Not to put too much emphasis on engineering,but it does start with hiring the most capable people.Itsaconstantchallengeaswegetmoresophisticated,to keep the technology operational, he adds. One challenge that weve really been focusing on is the ability to simplify. Ease of use and ease of training has been a huge focus, and thats a chal-lenge to take complex things and present them in such a way that theyre simple.DCI TODAYThese days, John Mercer and Peter Hambling, who also holds thetitleofcompanypresident,arestillverymuchactivein company operations. Mercers son, Matt, is also involved in the business while the elder Mercer spends the majority of his time with a new company that works on developing automatic pilot systems for helicopters. Although maybe not what they expected when they began theircareersinaviation,MercerandHamblingareproudof whattheyvebeenabletoaccomplishinthedirectionaldrill-ing market. Theyve even continued their love of ying as they occasionally use Hamblings World War II bomber to visit cus-tomers.

I think my hands-on involvement, and the fact that my crews see me working as hard as I expect them to work, moti-vates them to do their best. We do qual-ity work; and we do it on time.

ONE BORE, MULTIPLE OBSTACLESLongtimecustomerCrestwoodMid-stream Partners, headquartered in Hous-ton, approached Cline about installing a naturalgasgatheringpipelinethrough the heart of Arkansas rugged, rocky ter-rain.

Theonly hesitancewashisabilitytoprovide Crestwoodwithanaccuratecostesti-mate. At rst I told them [Crestwood] this probably was not the job for me, Cline says. I knew the Vermeer drill was capa-ble of completing a bore of that length and in those conditions. But it was dif-cult to estimate with a lot of certainly the amount of time it would take, given all the unpredictable variables. We real-ly hadnt completed a continuous bore combining all those obstacles and chal-lenges before.ButCrestwoodwaspersistent.Cline hadalwaysbeentheircontractorof choiceonjobslocatedwithinreason-WHERE THERES A WILL, THERES A WAYTreacherous terrain, layers of rock and a cavernous river crossing all in one continuous bore tested the trenchlessskills of an Arkansas underground contractor.By Randy HappelThe drill plan specied a continuous bore of 1,170 ft that included a 100-ft underground river crossing at a depth of 150 ft approximately 480 ft into the route.
