Big record for small boring

A Robbins Mixed Ground Cutterhead has been used in a record breaking distance for a small boring unit.

Tunnelling around the world

Trenchless International takes a look at some of the exciting tunnelling projects around the world.

Essential infrastructure is being rapidly expanded across China. One of the largest projects, the second West – East Gas Transmission Pipeline, is using Trenchless Technology to protect sensitive environments.

Magnetic steering of CSG wells

Jamie Dorey

The application of Trenchless Technology is common in many important resource sectors including gas and oil. Here we discover how horizontal directional drilling is being used to access coal seam gas.

Journal review

Environmental considerations for pipeline construction with horizontal directional drilling are discussed in the latest edition of The Journal of Pipeline Engineering (JPE). Here, Editor-in-Chief John Tiratsoo outlines an article discussing horizontal directional drilling construction methods.

Crossing the Athabasca River

Fort McMurray is the major urban centre within the Regional Municipality of Wood Buffalo, located in northeast Alberta, Canada, the town is situated just south of a major oilsands development. To service the expansive urban growth in the area, the municipality has invested in major infrastructure upgrades, including twin sanitary sewer forcemain crossing of the Athabasca River.

New certificate for HDD

InfraTrain New Zealand has launched an extensively revised qualification for horizontal directional drilling (HDD), which has been developed in partnership with the trenchless industry.

Renovation of pressure pipelines – quality assurance with ISO standards

Wim Elzink, Product Manager Wavin Overseas B.V.

Pressure pipelines are often in urgent need of rehabilitation. Here Wim Elzink looks at renovation options by lining with plastics pipes – in particular with polyethylene pipes – using a variety of techniques.

Saxony sewer sees the light

The rehabilitation of 146 metres of oval-profile DN 600/900 as part of the comprehensive restoration of Schloss Hubertusburg, a cultural heritage site in Wermsdorf in the German state of Saxony, has been achieved with light cured CIPP.

Sewer rehabilitation using epoxy resin injection

Paul Heenan, KA-TE PMO AG

The evolution in the repair of underground infrastructure such as water and wastewater pipes has resulted in the development of a highly competitive market in relining options. Here Paul Heenan from KA-TE PMO AG reflects on the importance of independent testing in the development and use of new products.

The state of road gully systems in Germany Part 1

Dr-Ing R Stein and Dipl-Ing H Cakmak, S & P Consult Bochum GmbH

The maintenance of road gully systems in Germany is often a neglected component of the wastewater network. This is part one of the analysis of a survey conducted to assess the cleaning, inspection and rehabilitation of road gullies in Germany.

CSM shaft construction

Norman Joyal, Associate, Jacobs Associates

The trenchless industry is technologically advanced and consistently innovative. Cutter soil mixing technology is one such example that has been developed to construct shafts for microtunnelling projects. Norman Joyal reports here about one of the first projects in the United States using this technology to build microtunnelling shafts.

New methods for box culvert pipeline construction

Tomo Morita, Hideki Shimada, Takashi Sasaoka, Kikuo Matsui, Fumihiko Matsumoto and Eiji Sakai

Circular pipes have been used for over a century to construct infrastructure in urban areas. Rectangular pipes, on the other hand, and in particular pipes installed by pipe jacking, are a fairly recent development. In this article the authors describe the development and assessment of a rectangular pipe jacking system.

Crossings: from São Paulo to Rio de Janeiro

GDK is currently completing construction on Petrobras’ GASTAU Project, which includes a 28 inch diameter, 97 kilometre natural gas pipeline extension running from the north coast of Brazil to 760 metre elevated plains between the cities of São Paulo and Rio de Janeiro, involving numerous river and road crossings.

Large-scale pipe bursting in the city of Campinas

A water authority in Campinas, Brazil, has purchased trenchless machinery to replace and enlarge existing drinking water pipelines.

Vacuum sewage disposal taken a step further

Vacuum systems are becoming a popular choice for the drainage of municipal sewage. SEKISUI SPR Europe GmbH has an innovative technology that combines all the advantages of vacuum systems and offers enormous potential for the global wastewater market.

Report from ICPTT 2009: Shanghai, China

The inaugural International Conference on Pipelines and Trenchless Technology (ICPTT), held in Shanghai, China from 19–21 October 2009, provided a forum for 80 presentations addressing the latest projects and technology for the water, sewer, gas and oil industries.

Trenchless Middle East Abu Dhabi 2010 expands

Due to the popularity of Trenchless Middle East Abu Dhabi 2010 the organisers have expanded the exhibition and opened up the East wing of the Great Tunb Hall to accommodate more exhibitors. Record numbers for both the conference and the exhibition are expected.
