CCI Paper is Published in 2020 Edition of GLSA Trenchless Journal
We are pleased to announce that in the 2020 edition of the Great Lakes, St. Lawrence & Atlantic Trenchless Journal, CCI’s Sam Wilson and Jeff Miller along with Adam Van Nood from Marathon Underground had their paper “Shore Approach Horizontal Directional Drill Crossings into the Bay of Fundy, New Brunswick” published. Way to go guys!
Shore Approach Horizontal Directional Drill Crossings into the Bay of Fundy, New Brunswuick
Authors: Sam Wilson P.Eng, CCI Inc, Edmonton, Alberta Jeff Miller E.I.T., CCI Inc, Edmonton, Alberta Adam Van Nood, Marathon Underground, Ottawa, Ontario
Abstract New Brunswick Power Transmission Corporation (NB Power) is constructing the Fundy Isles Transmission Power Line Project which consists of 69 kV Submarine Cables from Deer Island, NB to Campobello Island, NB and from Campobello Island to Grand Manan Island, NB. This project will provide electricity to the islands and will replace existing cables installed in 1978 and nearing the end of their service life.
NB Power requested that the connection between the submarine and the land-based sections of the project be completed utilizing the Horizontal Directional Drill (HOD) methodology to mitigate any concerns of future exposure due to erosion from the large tidal action within the bay. The HOD crossings were to include the installation of three HOPE conduits, one 16-inch 0.0. HOPE conduit along with two spare 3.5-inch HOPE conduits for future corrosion protection measures inside a 24″ common borehole. The project included four shore approach crossings, designed to be progressed through 0-50% ROD Mafic Tuft, Shale bedrock, and overburden materials.
Marathon Underground (Marathon) was successful in the tendering process for the project. CCI Inc. (CCI) was subcontracted to assist with production of feasible designs and provide HOD construction experience and support.
The unique nature of the shore approach methodologies, space constraints, marine activities, and difficult ground conditions at the crossing locations culminated in complicated conditions for HOD installations.
Through comprehensive engineering design, significant combined HOD experience, and Marathon’s ability to adapt to onsite conditions, two of the four crossings were successfully completed by HOD methods and two were completed with open cut methodologies with all completion dates meeting the required in-service date.
This article will discuss the challenges faced during both the design and construction phases of the shore approach crossings.

CCI & Associates Welcomes Neil Smith as Managing Director
— Corporate Announcement —
Welcome to the CCI Group of Companies Neil Smith, Managing Director for CCI & Associates Inc.
Mr. Neil Smith’s role will be to further develop CCI & Associates Engineering and EPC capabilities for specialized projects. He will be based out of our Houston office.
Neil graduated, with honors, with a Bachelor of Science in Civil Engineering from the University of Manchester in 1983. He is a Chartered Engineer and a Member of the Institution of Civil Engineers.
Neil brings, to CCI & Associates and its clients, 30 years’ HDD experience in complex, long and large diameter Horizontal Directional Drilling (HDD) crossings using steel, HDPE and FPVC pipe, at environmentally sensitive sites, in rural and congested urban areas, for shore landings and offshore in open waters. He has been instrumental in enabling the advancement of trenchless technology to benefit the industry and enable optimum project solutions.
Neil has over 30 years’ experience in leading international HDD contracting companies. Before assuming executive management roles, he gained experience in the HDD sector as project engineer, site manager, project manager and general manager. Neil’s accomplishments include building world class companies, delivering many challenging and significant projects (several recognized with industry awards) and the development of niche businesses in marine based HDD crossings (shore approaches and water-to-water crossings).
Neil has won multiple awards for his work with trenchless technology groups. In years past, he has been active in trade specific professional organizations and served as the President of the Directional Crossing Contractors Association.
The CCI Group of Companies are pleased to have Neil join our team.
Slurry Density and Hoop Stress During HDD Installation – Are they Underestimated
CCI & Associates continues to stay at the fore front of Horizontal Directional Drilling methods and designs through continued education and research by the employees. Recently a CCI Project Manager and University of Alberta Ph. D Research Associate, Ashkan Faghih completed a paper; Slurry Density and Hoop Stress During HDD Installation – Are they Underestimated?
The paper was then submitted to a research poster competition held at the NASTT No-Dig Show earlier this year. Ashkan’s poster was judged among 20 North American Universities and awarded second prize!
Ashkan’s paper looks at the importance of assuming a heavy slurry for hoop stress calculations when designing a horizontal direction drill. It also describes that external hoop stress on a pipe product during the pullback process is particularly high and the necessity of including a safety factor to the pipe analysis. Ashkan goes on to refer to data collected at several HDD installation sites and explains how the data “…identifies the need to improve design assumptions”. This type of research is applicable to many engineers designing HDD pullbacks and the increased knowledge betters the industry as a whole.
Research papers like this one, ensure that every horizontal directional drill CCI works on is of the highest standards. At CCI & Associates, the mission continues to be to deliver service excellence in a safe and timely manner through the application of our specialized knowledge and experience.
